PART I

Item 1.    Business.

All references in this report to “Registrant”, “Company”, “Schlumberger”, “we” or “our” refer to Schlumberger Limited and its consolidated subsidiaries.

Founded in 1926, Schlumberger is the world’s leading oilfield services company, supplying technology, project management and information solutions that optimize performance in the oil and gas industry. As of December 31, 2007, the Company employed approximately 80,000 people of over 140 nationalities operating in approximately 80 countries. Schlumberger has principal executive offices in Houston, Paris, and The Hague and consists of two business segments – Schlumberger Oilfield Services and WesternGeco. Schlumberger Oilfield Services is the world’s largest oilfield services company supplying a wide range of technology services and solutions to the international petroleum industry. WesternGeco is the world’s most technologically advanced surface seismic company.

Schlumberger Oilfield Servicesis the world’s leading provider of technology, project management and information solutions to the international oil and gas exploration and production industry. Schlumberger Oilfield Services manages its business through 31 GeoMarket* regions, which are grouped into four geographic areas: North America, Latin America, Europe/CIS/Africa and Middle East & Asia. The GeoMarket structure offers customers a single point of contact at the local level for field operations and brings together geographically focused teams to meet local needs and deliver customized solutions.

Schlumberger invented wireline logging as a technique for obtaining downhole data in oil and gas wells. Today, Schlumberger Oilfield Services operates in each of the major oilfield service markets, providing services that cover the entire life cycle of the reservoir. These services, in which Schlumberger holds a number of market leading positions, are organized into a number of technology-based product and service lines, or Technologies, to capitalize on technical synergies and introduce innovative solutions within the GeoMarket regions. The Technologies are also responsible for overseeing operational processes, resource allocation, personnel and quality, health, safety and environmental matters in the GeoMarket.

The Technologies are:

· Wireline – provides the information necessary to evaluate the subsurface formation rocks and fluids to plan and monitor well construction, and to monitor and evaluate well production. Wireline offers both open-hole and cased-hole services.

· Drilling & Measurements – supplies directional-drilling, measurement-while-drilling and logging-while-drilling services for all well profiles.

· Well Testing – provides exploration and production pressure and flow-rate measurement services both at the surface and downhole. The Technology also provides tubing-conveyed perforating services.

· Well Services – provides services used during oil and gas well drilling and completion as well as those used to maintain optimal production throughout the life of a well. The services include pressure pumping, well cementing and stimulation operations as well as intervention activities. The Technology also develops coiled-tubing equipment and services.

· Completions – supplies well completion services and equipment that include gas-lift and safety valves as well as a range of intelligent well completions technology and equipment.

· Artificial Lift – provides production optimization services using electrical submersible pumps and associated equipment.

3

Part I, Item 1 

· Data & Consulting Services – supplies interpretation and integration of all exploration and production data types, as well as expert consulting services for reservoir characterization, production enhancement, field development planning and multi-disciplinary reservoir and production solutions.

· Schlumberger Information Solutions – provides consulting, software, information management and IT infrastructure products and services that support core oil and gas industry operational processes.

One other service line, Integrated Project Management (IPM), provides consulting, project management and engineering services for use in well construction and production management projects to leverage Schlumberger technology expertise.

Supporting the Technologies are 20 research and engineering centers. Through this organization, Schlumberger is committed to advanced technology programs that enhance oilfield efficiency, lower finding and producing costs, improve productivity, maximize reserve recovery and increase asset value while accomplishing these goals in a safe and environmentally sound manner.

Schlumberger Oilfield Services uses its own personnel to market its products and services. The customer base, business risks and opportunities for growth are essentially uniform across all services. There is a sharing of manufacturing and engineering facilities as well as research centers, and the labor force is interchangeable. Technological innovation, quality of service, and price differentiation are the principal methods of competition, which varies geographically with respect to the different services offered. While there are numerous competitors, both large and small, Schlumberger believes that it is an industry leader in providing wireline logging, well testing, measurement-while-drilling, logging-while-drilling and directional-drilling services, as well as fully computerized logging and geoscience software and computing services. A large proportion of Schlumberger offerings are non-rig related; consequently, revenue does not necessarily correlate to rig count fluctuations.

Schlumberger is a 40% owner in M-I Drilling Fluids—a joint venture with Smith International—which offers the drilling and completion fluids used to stabilize subsurface rock strata during the drilling process and minimize formation damage during completion and workover operations.

WesternGeco,the world’s most technologically advanced seismic company, provides comprehensive reservoir imaging, monitoring and development services with the most extensive seismic crews and data processing centers in the industry as well as a leading multiclient seismic library. Services range from 3D and time-lapse (4D) seismic surveys to multi-component surveys for delineating prospects and reservoir management. WesternGeco benefits from full access to the Schlumberger research, development and technology organization and shares similar business risks, opportunities for growth, principal methods of competition and means of marketing as Schlumberger Oilfield Services. Seismic solutions include proprietary Q* technology for enhanced reservoir description, characterization and monitoring throughout the life of the field—from exploration through enhanced recovery. Other WesternGeco solutions include development of controlled-source electromagnetic and magneto-telluric surveys and their integration with seismic data.

Positioned for meeting a full range of customer needs in land, marine and shallow-water transition-zone services, WesternGeco offers a wide scope of technologies and services:

· Land Seismic – provides comprehensive resources for seismic data acquisition on land and across shallow-water transition zones.

· Marine Seismic – provides industry-standard marine seismic acquisition and processing systems as well as a unique industry-leading, fully calibrated single-sensor marine seismic system that delivers the seismic technology needed for new-generation reservoir management.

· Multiclient Services – supplies high-quality seismic data from the multiclient library, including industry-leading Q technology data.

4

Part I, Item 1 

· Reservoir Services – provides people, tools and technology to help customers capture the benefits of a completely integrated approach to locating, defining and monitoring the reservoir.

· Data Processing – offers extensive seismic data processing centers for complex data processing projects.

· Electromagnetics – provides controlled-source electromagnetic and magneto-telluric data acquisition and processing.

Acquisitions

Information about acquisitions made by Schlumberger appears in Note 4 of theConsolidated Financial Statements.

GENERAL

Research Centers

Research to support the engineering and development efforts of Schlumberger activities is principally conducted at Cambridge, Massachusetts, United States; Cambridge, England; Stavanger, Norway; Moscow, Russia; and Dhahran, Saudi Arabia.

Patents

While Schlumberger seeks and holds numerous patents covering various products and processes, no particular patent or group of patents is considered material to Schlumberger’s business.

Seasonality

Although weather and natural phenomena can temporarily affect delivery of oilfield services, the widespread geographic location of such services precludes the overall business from being characterized as seasonal. However, because oilfield services are provided predominantly in the Northern Hemisphere, severe weather can temporarily affect the delivery of such services and products.

Customers and Backlog of Orders

No single customer exceeded 10% of consolidated revenue. Oilfield Services has no significant backlog due to the nature of its business. The WesternGeco backlog at December 31, 2007 was $1.2 billion (2006: $1.1 billion), the majority of which is expected to be realized in 2008.

Government Contracts

No material portion of Schlumberger’s business is subject to renegotiation of profits or termination of contracts by the United States or other governments.

Employees

As of December 31, 2007, Schlumberger had approximately 80,000 employees.

Financial Information

Financial information by business segment for the years ended December 31, 2007, 2006 and 2005 is provided in Note 18 of theConsolidated Financial Statements.

Item 1A.    Risk Factors.

The following discussion of risk factors contains “forward-looking statements,” as discussed immediately following Item 7A. of this Report. These risk factors may be important to understanding any statement in this Report or elsewhere. The following information should be read in conjunction with Management’s Discussion and Analysis, and the consolidated financial statements and related notes incorporated by reference in this Report.

We urge you to carefully consider the risks described below, as well as in other reports and materials that we file with the SEC and the other information included or incorporated by reference in this Report. If any of the risks described below or elsewhere in this Report were to materialize, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also adversely affect our business and operations.

Demand for the majority of our oilfield services is substantially dependent on the level of expenditures by the oil and gas industry. A substantial or an extended decline in oil or gas prices could result in lower expenditures by the oil and gas industry and reduce our operating revenue.

6

Part I, Item 1A 

Demand for the majority of our oilfield services is substantially dependent on the level of expenditures by the oil and gas industry for the exploration, development and production of crude oil and natural gas reserves, which are sensitive to oil and natural gas prices and generally dependent on the industry’s view of future oil and gas prices. Oil and gas prices have historically been volatile and are affected by numerous factors, including:

· demand for energy, which is affected by worldwide population growth, economic development and general economic and business conditions;

· the ability of the Organization of Petroleum Exporting Countries, or OPEC, to set and maintain production levels for oil;

· oil and gas production by non-OPEC countries;

· political and economic uncertainty and socio-political unrest;

· the level of worldwide oil exploration and production activity;

· the cost of exploring for, producing and delivering oil and gas;

· technological advances affecting energy consumption; and

· weather conditions.

The oil and gas industry has historically experienced periodic downturns, which have been characterized by diminished demand for our oilfield services and downward pressure on the prices we charge. A significant downturn in the oil and gas industry could result in a reduction in demand for oilfield services and could adversely impact our operating results.

A significant portion of our revenue is derived from our non-United States operations, which exposes us to risks inherent in doing business in each of the approximately 80 countries in which we operate.

Our non-United States operations accounted for approximately 76% of our consolidated revenue in 2007, 73% in 2006 and 75% in 2005. Operations in countries other than the United States are subject to various risks, including:

· unsettled political and economic conditions in certain areas;

· exposure to possible expropriation or other governmental actions;

· social unrest, acts of terrorism, war or other armed conflict;

· confiscatory taxation or other adverse tax policies;

· deprivation of contract rights;

· trade restrictions or embargoes imposed by the United States or other countries;

· restrictions on the repatriation of income or capital;

· exchange controls;

· inflation; and

· currency fluctuations and devaluations.

In addition, we are subject to risks associated with our operations in countries, including Iran, Syria, Sudan and Cuba, which are subject to trade and economic sanctions or other restrictions imposed by the United States or other governments or organizations.

7

Part I, Item 1A 

If any of the risks described above materialize, it could reduce our earnings and our cash available for operations.

We are also subject to risks related to investment in our common stock in connection with certain US state divestment or investment limitation legislation applicable to companies with operations in these countries, and similar actions by some private investors, which could adversely affect the market for our common stock.

Environmental compliance costs and liabilities could reduce our earnings and cash available for operations.

We are subject to increasingly stringent laws and regulations relating to importation and use of hazardous materials, radioactive materials and explosives, environmental protection, including laws and regulations governing air emissions, water discharges and waste management. We incur, and expect to continue to incur, capital and operating costs to comply with environmental laws and regulations. The technical requirements of these laws and regulations are becoming increasingly expensive, complex and stringent. These laws may provide for “strict liability” for damages to natural resources or threats to public health and safety. Strict liability can render a party liable for damages without regard to negligence or fault on the part of the party. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances.

We use and generate hazardous substances and wastes in our operations. In addition, many of our current and former properties are or have been used for industrial purposes. Accordingly, we could become subject to potentially material liabilities relating to the investigation and cleanup of contaminated properties, and to claims alleging personal injury or property damage as the result of exposures to, or releases of, hazardous substances. In addition, stricter enforcement of existing laws and regulations, new laws and regulations, the discovery of previously unknown contamination or the imposition of new or increased requirements could require us to incur costs or become the basis of new or increased liabilities that could reduce our earnings and our cash available for operations. We believe we are currently in substantial compliance with environmental laws and regulations.

We could be subject to substantial liability claims, which would adversely affect our results and financial condition.

Certain equipment used in the delivery of oilfield services, such as directional drilling equipment, perforating systems, subsea completion equipment, radioactive materials and explosives and well completion systems, are used in hostile environments, such as exploration, development and production applications. An accident or a failure of a product could cause personal injury, loss of life, damage to property, equipment or the environment, and suspension of operations. Our insurance may not adequately protect us against liability for some kinds of events, including events involving pollution, or against losses resulting from business interruption. Moreover, in the future we may not be able to maintain insurance at levels of risk coverage or policy limits that we deem adequate. Substantial claims made under our policies could cause our premiums to increase. Any future damages caused by our products that are not covered by insurance, or are in excess of policy limits or are subject to substantial deductibles, could reduce our earnings and our cash available for operations.

If we are unable to maintain technology leadership in the form of services and products, this could affect any competitive advantage we hold.

If we are unable to develop and produce competitive technology or deliver them to our clients in the form of services and products in a timely and cost-competitive manner in the various markets we serve, it could materially reduce our operating revenue and net income.

8

Part I, Item 1A, 1B, 2 

Limitations on our ability to protect our intellectual property rights, including our trade secrets, could cause a loss in revenue and any competitive advantage we hold.

Some of our products or services, and the processes we use to produce or provide them, have been granted United States patent protection, have patent applications pending or are trade secrets. Our business may be adversely affected if our patents are unenforceable, the claims allowed under our patents are not sufficient to protect our technology, our patent applications are denied, or our trade secrets are not adequately protected. Our competitors may be able to develop technology independently that is similar to ours without infringing on our patents or gaining access to our trade secrets.

We may be subject to litigation if another party claims that we have infringed upon its intellectual property rights.

The tools, techniques, methodologies, programs and components we use to provide our services may infringe upon the intellectual property rights of others. Infringement claims generally result in significant legal and other costs and may distract management from running our core business. Royalty payments under licenses from third parties, if available, would increase our costs. If a license were not available we might not be able to continue providing a particular product or service, which would reduce our operating revenue. Additionally, developing non-infringing technologies would increase our costs.

Failure to obtain and retain skilled technical personnel could impede our operations.

We require highly skilled personnel to operate and provide technical services and support for our business. Competition for the personnel required for our businesses intensifies as activity increases. In periods of high utilization it may become more difficult to find and retain qualified individuals. This could increase our costs or have other adverse effects on our operations.

Severe weather conditions may affect our operations.

Our business may be materially affected by severe weather conditions in areas where we operate. This may entail the evacuation of personnel and stoppage of services. In addition, if particularly severe weather affects platforms or structures, this may result in a suspension of activities until the platforms or structures have been repaired. Any of these events may have a material adverse effect on our operating revenue.

Item 1B.    Unresolved Staff Comments.

None.

Item 2.    Properties.

Schlumberger owns or leases manufacturing facilities, administrative offices, service centers, research centers, data processing centers, sales offices and warehouses throughout the world. No significant lease is scheduled to terminate in the near future, and Schlumberger believes comparable space is readily obtainable should any lease expire without renewal. Schlumberger believes its properties are generally well maintained and adequate for the intended use.

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis contains forward-looking statements including, without limitation, statements relating to our plans, strategies, objectives, expectations, intentions and resources. Such forward-looking statements should be read in conjunction with our disclosures under “Item 1A. Risk Factors” of this Report.

Executive Overview

Oil markets exhibited considerable variation in 2007. The OPEC production cuts of November 2006 that provoked the recovery in the price per barrel entering the winter period in the Northern Hemisphere were overweighed by mild early winter weather conditions that lead to WTI (West Texas Intermediate) falling to the year low of $50.50-per-barrel by mid-January. However, price for WTI ending the year within striking distance of $100-per-barrel. Market fundamentals supported this upwards trend as evidenced by the need for an OPEC production increase in September and by the reduction in the days of forward cover of OECD (Organization for Economic Co-operation and Development) oil stocks which had fallen below 53 days by the end of year. Spare production margins remained narrow, driven by geopolitical events and inherent production decline, while non-OPEC production levels continued to be revised downwards as project delays added further uncertainty to performance.

In natural gas markets, the weak prices seen at the beginning of 2007 strengthened significantly as colder weather drove demand in North America. The region’s gas supply results from four separate components that include domestic production, LNG (Liquefied Natural Gas) imports, Canadian exports to the US, and US exports to Mexico. Changes in any of these affect overall supply and during the year higher production and higher imports, particularly of LNG, led to above-average levels of natural-gas storage in the US with consequent weaker commodity pricing later in the year.

Maintaining the production base for both oil and natural gas continues to face challenges. In both cases, the aging of reservoirs that have been in production for many decades gives rise to increasing production decline rates that require constant stemming, while weak reserves replacement ratios and heightened resource nationalism dictate that exploration for new hydrocarbon deposits—in increasingly more remote areas and complex geologies—must increase.

Within this context, Schlumberger revenue in 2007 grew by 21%, driven by strong demand for oilfield services, particularly overseas. Year-on-year growth rates reached 31% in Middle East & Asia, 30% in Europe/CIS/Africa and 29% in Latin America. In North America however, revenue was essentially flat relative to 2006. All Oilfield Services Technologies showed double-digit improvement, with Drilling & Measurements, Well Testing and Integrated Project Management recording the highest overall growth rates year-on-year.

The business pattern that emerged in 2007—with significant differences in growth inside and outside North America—marked a change in the oil and gas industry growth cycle. There were two reasons for this. North American activity is largely driven by natural gas exploration and production and the number of active drilling rigs proved sufficient to maintain satisfactory levels of production—at least in the short term. In addition, the strong international growth was mainly directed to oil and primarily land-based as the available offshore rig fleet reached full utilization—particularly in deep water.

New Schlumberger products and services contributed to growth in 2007. In line with the need for improved well performance for example, particularly through stimulation of natural gas wells, Schlumberger introduced the Contact* family of staged fracturing and completion services early in the year. These services penetrated a number of key markets with a broad range of efficient and effective stimulation technologies. In North America, Contact services demonstrated their ability to place fracture treatments more accurately while stimulating multiple productive sands in a single operation to increase production and lower cost. Contact technologies were also demonstrated and deployed in Gabon, Kuwait and Saudi Arabia, with significant production improvements in every case.

Part II, Item 7 

Within this landscape, Schlumberger made further progress in areas where competitive advantage exists in technology and business model. In Russia, Schlumberger further expanded operations through the acquisition of TyumenPromGeofizika, a West Siberian wireline logging company. Elsewhere in Siberia, manufacturing activities increased as Wireline and Well Services began assembly of perforating and pumping equipment in Tyumen. Research and engineering activity accelerated with the opening of the new Moscow research center and the extension of the engineering center in Novosibirsk. And to address the needs of the increased staff in Russia, the Siberian Training Center partially opened for a number of training courses at the end of the year with full operation expected early in 2008.

Russia also benefited from expanding take-up of Integrated Project Management services in Siberia. Similar operations began in other GeoMarket regions in Europe/CIS/Africa, and there was further strong growth in the well construction businesses in Latin America, where a new phase of deeper, hotter and more complex operations started in Mexico. These events are consistent with our goal of growing project management services at a much higher rate than the rest of the business.

Growth at WesternGeco, where full-year 2007 revenue increased by 20% over 2006, matched the overall trend set by Oilfield Services. This was driven by demand for marine seismic and multiclient data sales while Q-Technology* revenue increased again to a new high of $1.14 billion, up 57% versus 2006. Vessel utilization for the year reached 93%, with half of the marine fleet now equipped with Q-Technology systems. The strength of the seismic market, particularly in marine services, led us to review our long-term plans for the fleet, resulting in the acquisition of Eastern Echo in November. The six new high-performance, high-capacity vessels on order are ideally suited to the exploration and development markets of the future, and all six will be fitted with Q-Technology equipment.

In addition to the acquisitions of TyumenPromGeofizika and Eastern Echo, technology-based growth was furthered through a number of smaller acquisitions made during the year. These included Insensys Oil & Gas fiber-optic technology for the expanding subsea market, VIPS reservoir software and interpretation expertise to accelerate Schlumberger strength in geomechanics, InnerLogix information management technology for data quality improvement and Geosystem electromagnetic technology to expand WesternGeco electromagnetics solutions. The technology portfolio was also boosted by the acquisition of a further 5.5% share in Framo Engineering AS to take the Schlumberger holding to a majority 52.75%. Framo is a Norwegian-based company providing multiphase booster pumps, flow metering equipment and swivel stack systems. We will begin consolidating the results of Framo in the first quarter of 2008.

In early 2007, we reiterated our view that while Schlumberger would continue to see high growth through the end of the present decade, growth rates would ultimately slow from the breakneck pace of the earlier part of 2006. Strong growth was indeed seen in 2007, but the shorter-term outlook for 2008 has become more complex, with several factors set to influence the business in the coming year. On the positive side, growth in land activity outside North America will remain strong, and seismic exploration services worldwide will remain in high demand on land and offshore as the industry gears up for an expanded exploration phase. However, in North America we do not expect levels of natural gas drilling to vary greatly in the absence of severe winter weather. Overall growth will also be restricted by the high utilization of the existing offshore rig fleet and the fact that only limited new builds will enter the market over the next 12 months. This will make activity vulnerable to operating efficiency.

Maintaining and increasing the production base for both oil and natural gas will continue to be challenging. The aging of reservoirs that have been in production for many decades requires high levels of activity in order to stem decline, while weak reserves replacement ratios and heightened resource nationalism dictate that exploration for new hydrocarbon deposits—in ever more remote areas and complex geologies—must increase.

In the longer term, current levels of drilling are insufficient to meaningfully slow decline rates, improve reservoir recovery or add sufficient new production capacity. The explosion in exploration licenses awarded in the last three years, the continual expansion of the number of new offshore rigs being ordered for delivery

Oilfield Services

Fourth Quarter 2007 Results

Fourth-quarter revenue of $5.44 billion was 6% higher sequentially and 18% higher as compared to the fourth quarter of 2006. Sequential revenue increases were highest in the Middle East & Asia Area led by the Arabian, China/Japan/Korea and India GeoMarkets*, followed by the Latin America Area where growth was strongest in the Mexico/Central America, Latin America South and Peru/Colombia/Ecuador GeoMarkets. In the Europe/CIS/Africa Area, increases were led by the North Sea, Caspian and Continental Europe GeoMarkets. Growth was also recorded in North America, led primarily by the Canada and US Gulf Coast GeoMarkets. Among Schlumberger Technologies, Artificial Lift Systems, Completions Systems and Schlumberger Information Solutions (SIS) registered strong growth due to seasonal end-of-year product sales.

Fourth-quarter pretax operating income of $1.54 billion increased 2% sequentially and 16% as compared to the fourth quarter of 2006. Sequentially, growth was driven by demand for higher-margin Drilling & Measurements services in the Middle East & Asia Area and by increased product sales in Artificial Lift Systems in Europe/CIS/Africa and Middle East & Asia, and by Completions Systems product sales in the Middle East & Asia and Latin America. However, these increases were offset by pricing erosion for well stimulation related activities on land in the US; exceptional weather-related and operational delays in Mexico/Central America; and weather and seasonal effects in the US West, North Sea and East Russia GeoMarkets. These events resulted in an overall pretax operating margin in the fourth quarter of 28.2% as compared to 29.4% in the third quarter of 2007.

19

Part II, Item 7 

North America

Revenue of $1.33 billion increased 3% sequentially but decreased 7% as compared to the fourth quarter of 2006. Pretax operating income of $338 million decreased 3% sequentially and 23% year-on-year.

Sequentially, revenue in the Canada GeoMarket continued to grow led by demand for Well Services and Wireline technologies. In the US Gulf Coast GeoMarket, activity partially recovered from the slowdown experienced during the hurricane season of the third quarter with higher demand for Wireline, Well Testing and Well Services technologies. In addition, higher SIS product sales were recorded across the Area. This performance was largely offset by the continuing pricing erosion in well stimulation related activities in the US land GeoMarkets, seasonal land access constraints in the west, and by lower activity in Alaska.

Pretax operating margin for the Area declined sequentially from 26.9% to 25.4% due to the lower pricing environment for well stimulation related services in the US land and Canada GeoMarkets, as well as lower operating leverage in Alaska and Canada. This was partially offset by a more favorable activity mix and higher operating efficiency in the US Gulf Coast GeoMarket together with the Area-wide SIS product sales.

Latin America

Revenue of $943 million increased 9% sequentially and 40% as compared to the fourth quarter of 2006. Pretax operating income of $208 million increased 2% sequentially and 47% year-on-year.

Sequential revenue growth was recorded in all GeoMarkets primarily driven by IPM activities in Mexico/Central America, Peru/Colombia/Ecuador and Venezuela/Trinidad & Tobago. Increased demand for Well Testing technologies and higher sales of Artificial Lift Systems, Completions Systems and SIS products in Latin America South, together with higher sales of Artificial Lift Systems and Completions Systems products in the Mexico/Central America and Peru/Colombia/Ecuador GeoMarkets, also contributed to growth.

Pretax operating margin declined sequentially from 23.7% to 22.1% primarily due to the activity mix in the Mexico/Central America GeoMarket, which was affected by higher IPM project startup and third-party costs as well as by flooding in the south and operational delays offshore. These startup costs are expected to continue for the next few quarters. A lower mix of higher-margin Drilling & Measurements activity in Venezuela/Trinidad & Tobago and higher-margin Wireline technology in Peru/Colombia/Ecuador also contributed to this result.

Europe/CIS/Africa

Revenue of $1.77 billion increased 4% sequentially and 23% as compared to the fourth quarter of 2006. Pretax operating income of $493 million was flat sequentially but increased 28% year-on-year.

Sequentially, the North Sea GeoMarket recorded the highest revenue growth driven by increased demand for Wireline and Well Services technologies together with higher Artificial Lift Systems and SIS product sales. Higher demand for Drilling & Measurements technologies in the Caspian GeoMarket, increased Artificial Lift Systems product sales in North Russia, and high demand for Drilling & Measurements, Well Services and Well Testing technologies in Continental Europe also contributed to growth. This performance was partially offset by the seasonal slowdown in Sakhalin and subdued activity in Nigeria.

Pretax operating margin declined sequentially from 29.2% to 27.9% due to the seasonal slowdown in Sakhalin, and to weather-related delays which led to reduced demand for higher- margin Drilling & Measurements and Well Testing technologies in the North Sea. A less favorable activity mix in the West & South Africa and North Africa GeoMarkets also contributed to this result.

Middle East & Asia

Revenue of $1.35 billion increased 10% sequentially and 30% as compared to the fourth quarter of 2006. Pretax operating income of $473 million increased 8% sequentially and 40% year-on-year.

20

Part II, Item 7 

The sequential growth in revenue resulted from high demand for Drilling & Measurements and Wireline technologies together with higher Completions Systems, Artificial Lift Systems and SIS product sales in the Arabian GeoMarket; higher demand for exploration-related Drilling & Measurements technologies and for Artificial Lift Systems products in Qatar; increased demand for Drilling & Measurements and Well Testing services in China/Japan/Korea; and higher deepwater exploration-driven demand for Wireline and Drilling & Measurements technologies together with higher SIS product sales in India.

The pretax operating margin of 35.0% as compared to 35.7% in the third quarter resulted from the more favorable activity mix in the Arabian and India GeoMarkets being offset by reduced demand for higher-margin Wireline, Well Services and Well Testing technologies in the Indonesia, Thailand/Vietnam and Australia/Papua New Guinea GeoMarkets.

Total Year 2007 Results

Full-year 2007 revenue of $20.31 billion increased 21% versus 2006, led by Area growth of 31% in the Middle East & Asia, followed by 30% in Europe/CIS/Africa and 29% in Latin America while North America remained essentially flat. Pretax operating income of $5.96 billion in 2007 was 28% higher than 2006.

Pretax operating margins of 29.3% improved 164 basis points (bps) in 2007 versus 2006. Higher activity and expansion of higher-margin new technology deployment across Europe/CIS/Africa, Middle East & Asia and Latin America Areas were the principal contributors to this performance. In North America, pricing erosion in pressure-pumping well-stimulation activities moderated year-on-year margin growth within the Area.

Among the GeoMarkets, the greatest increases in revenue were recorded in the North Sea, followed by Mexico, West & South Africa, Arabian and Venezuela/Trinidad & Tobago GeoMarkets.

Significant demand was seen for all Technologies led by Drilling & Measurements, Wireline, Well Testing, and Completions Systems as customers continued to improve exploration and production performance in the search for new hydrocarbon reserves and in the need to increase production and boost recovery from existing fields.

To adapt the existing Schlumberger GeoMarket structure to expanding activity levels worldwide, Qatar was established as a separate GeoMarket and new GeoMarkets were established in Russia and on land in the US, bringing the total number of GeoMarkets to 31.

North America

Revenue of $5.34 billion increased marginally over 2006 primarily due to higher demand for Drilling & Measurements, Well Testing and Wireline activities in the US Land Central, US Land North and the US Gulf Coast GeoMarkets. However, this performance was offset by pricing erosion in well stimulation activities across the Area.

Activity across US Land continued to grow driven by the increase in rig count and higher service intensity in unconventional natural gas reservoirs. However, weakness in natural gas prices and excess well stimulation-related pressure pumping capacity led to a year-on-year decline in pricing in stimulation related activities. The US Gulf Coast GeoMarket continued to grow driven by demand for exploration related activities.

In Canada year-on-year revenue declined sharply due to operator slowdown driven by weakness in natural gas prices and uncertainty over the fiscal regime.

Pretax operating margin declined by 167 bps to 28.8% primarily due to lower pricing in well stimulation related activities across the Area together with lower activity in Canada.

21

Part II, Item 7 

Latin America

Revenue of $3.30 billion in 2007 increased 29% over 2006 led by a surge in IPM related activity in Mexico following the budget-related slowdowns in the previous year, followed by the growth in exploration-related activities in the Peru/Columbia/Ecuador and Latin America South GeoMarkets. The Venezuela/Trinidad & Tobago GeoMarket also grew with higher rig count-driven activity in addition to finalization of the contracts related to drilling barges.

The Mexico GeoMarket recorded robust growth with the start of several integrated projects. Peru/Columbia/Ecuador and Latin America South witnessed strong growth in exploration-related activities. Demand was strong for all Technologies led by IPM, followed by Drilling & Measurements, Wireline and Well Testing services.

Pretax operating margin increased strongly by 358 bps to reach 22.9%. This increase resulted mainly from a favorable activity mix and improved pricing.

Europe/CIS/Africa

Revenue of $6.59 billion in 2007 increased 30% over 2006 with the highest growth recorded in the North Sea, West & South Africa and North Africa GeoMarkets.

Strong revenue increases were recorded in the North Sea, West & South Africa and North Africa driven by the expansion of exploration-related activities. GeoMarkets in Russia continued to grow strongly due to a combination of organic growth and the completion of the acquisition of Tyumenpromgeofizika during the second quarter of the year.

Pretax operating margins increased by 299 bps to reach 28.5%. This performance was due to a combination of increased activity, improved pricing and accelerated new technology deployment across most GeoMarkets partially offset by a pricing decline in well stimulation activities in the East Russia and subdued activity in Nigeria.

Middle East & Asia

Revenue of $4.88 billion in 2007 increased 31% over 2006 with the largest increases recorded in the Arabian GeoMarket, followed by East Mediterranean, Australia/Papua New Guinea, Qatar, Gulf and India.

The Australia/Papua New Guinea GeoMarket recorded the highest growth rate in the Area driven by higher exploration related activity. Growth in East Mediterranean, Qatar, Gulf and India resulted from higher exploration and development activity while the Arabian GeoMarket continued to grow, albeit at a lower rate than the previous year, as new rig additions slowed down in Saudi Arabia.

Pretax operating margin increased by 299 bps to an impressive 35.1%. This performance was driven by continued increase in activity and pricing increases together with deployment of higher-margin Wireline and Drilling & Measurements new technologies.

Total Year 2006 Results

Revenue of $16.76 billion increased 33% in 2006 versus 2005 driven by growth in oilfield services activities as operators responded strongly to increasing global hydrocarbon demand through renewed exploration and increased focus on production operations. Within the geographic Areas, North America revenue increased 40%, Europe/CIS/Africa increased 36%, Middle East & Asia increased 31% and Latin America increased 16%.

Pretax operating income of $4.64 billion in 2006 grew by 64% over 2005 resulting in operating margins climbing by 535 bps to reach 27.57%. Stronger activity, accelerating higher-margin new technology deployment and increased pricing across all Areas were the principal contributors to this performance.

22

Part II, Item 7 

Among the GeoMarkets, the greatest increases in revenue were recorded in US Land, followed by the Arabian, Russian, North Sea, US Gulf Coast, Canada, West & South Africa, Nigeria and North Africa GeoMarkets. The growth in Russia was driven by a combination of activity within the established GeoMarkets and the impact of the acquisition of PetroAlliance Services.

Significant demand was seen for all Technologies as customers sought to improve exploration and production performance while mitigating technical risk in the search for new hydrocarbon reserves and in the need to increase production and boost recovery from existing fields.

A number of key acquisitions were made during the year. These included the acquisition of the outstanding 49% of PetroAlliance Services in Russia; as well as TerraTek – a global leader in geomechanics measurements and analysis; Odegaard – a leader in advanced surface seismic data inversion software; and Reslink – a leading supplier of advanced completion solutions which offer a broad spectrum of engineering applications and products for sand management, zonal isolation and intelligent well completions.

North America

Revenue of $5.27 billion increased 40% over 2005 mainly driven by the US Land and US Gulf Coast GeoMarkets, which benefited from strong Well Services, Drilling & Measurements and Wireline activities coupled with continued pricing improvements. Increasing demand for Well Testing activities offshore also contributed to growth.

Sharply increased activity in the US Land GeoMarket led to strong equipment and personnel utilization, higher pricing and increased demand for high-tier, new-technology services. The US Gulf Coast GeoMarket rebounded strongly from the effects of the disastrous 2005 hurricane season with growth driven by a combination of new exploration and increased production-related activities.

Canada continued to grow due to strong demand for Drilling & Measurements and Wireline technologies. Growth was somewhat offset by lower Well Services activity in the coal bed methane and shallow gas areas in the second half of the year.

Pretax operating income of $1.60 billion was 72% higher than in 2005 led by the US Land and US Gulf of Mexico GeoMarkets. The steep growth was primarily due to continuing strength in pricing, particularly for Well Services, Wireline and Drilling & Measurements technologies, and a more favorable activity mix resulting from the deployment of higher-margin new-technology Drilling & Measurements, Wireline and Well Testing services.

Latin America

Revenue of $2.56 billion in 2006 increased 16% over 2005 led by the Venezuela/Trinidad & Tobago GeoMarket, followed by the Latin America South and Peru/Colombia/Ecuador GeoMarkets. Growth in the Area was impacted by budget-related activity slowdowns in Mexico together with geopolitical concerns in other parts of the region.

The Venezuela/Trinidad & Tobago GeoMarket recorded strong growth due to solid demand for Drilling & Measurements technologies. Well Services, Wireline, Completions and Artificial Lift technologies also contributed to growth. In Venezuela, discussions regarding new contracts for the drilling barges work and the settlement of certain outstanding receivables had progressed at the end of the year. Pending finalization of these new contracts, revenue recognition was deferred on certain work performed in the third and fourth quarters. As the costs associated with this work were also deferred, this did not have a significant impact on the Area’s pretax operating income.

The Latin America South GeoMarket registered strong growth due primarily to increased Well Services, Drilling & Measurements, IPM and Well Testing activities, while growth in the Peru/Colombia/Ecuador GeoMarket resulted from significant demand for Drilling & Measurements, Wireline and Artificial Lift technologies.

Part II, Item 7 

Pretax operating income of $495 million in 2006 increased 50% versus 2005. This increase resulted mainly from a favorable activity mix in IPM projects and improved operating efficiencies in Drilling & Measurements and Well Testing services.

Europe/CIS/Africa

Revenue of $5.05 billion in 2006 increased 36% over 2005 with the highest growth recorded in the North Sea, North Africa, Nigeria GeoMarkets and in Russia.

Strong revenue increases were recorded in Russia and other CIS countries despite the weather-related slowdown in the first quarter, due to a combination of organic growth within Schlumberger Technology lines and the impact of the acquisition of PetroAlliance Services. Renewed customer focus on exploration resulted in steep growth in the North Sea and North Africa GeoMarkets, while the West & South Africa and Nigeria GeoMarkets maintained a robust growth momentum.

Pretax operating income of $1.29 billion in 2006 increased 67% compared to 2005. All GeoMarkets contributed significantly through increased activity, improved pricing and accelerated new technology deployment.

Middle East & Asia

Revenue of $3.72 billion in 2006 increased 31% over 2005 with the largest increases recorded in the Arabian, East Africa & East Mediterranean and Gulf GeoMarkets.

Saudi Arabia continued aggressive growth rates as activity increased rapidly, distinguishing the Arabian GeoMarket as the fastest growing of all of the GeoMarkets.

Growth in the East Africa & East Mediterranean and Gulf GeoMarkets was principally attributed to higher activity in Drilling & Measurements and Wireline services. The Brunei/Malaysia/Philippines, Australia Papua New Guinea and Thailand/Vietnam/Myanmar GeoMarkets also contributed to growth.

All Technologies witnessed solid growth as activity increased and demand for new technology increased with significant progress in the deployment of Drilling & Measurements PowerDrive* and Scope* technologies to enable successful drilling of a number of complex borehole trajectories.

Pretax operating income of $1.20 billion in 2006 increased 49% compared to 2005. The steady increase in operating income and operating margins throughout the year was due to activity improvement across all GeoMarkets, significant price increases and accelerated new technology deployment.

WesternGeco

Fourth Quarter 2007 Results

Fourth-quarter revenue of $798 million increased 1% over the prior quarter and increased 11% compared to the same period last year. Pretax operating income of $272 million decreased 11% sequentially but increased 4% year-on-year.

Sequentially, Multiclient revenue increased 83% due to higher sales in North America, Africa and Asia. However, this increase was largely offset by a decrease in Marine revenue due to vessel transits between projects, several vessel dry docks, and lower vessel utilization.

Pretax operating margin declined sequentially from 38.6% to 34.1% as the high-margin Multiclient activity was more than offset by the lower Marine vessel utilization.

Part II, Item 7 

Total Year 2007 Results

Full-year 2007 revenue of $2.96 billion increased 20% versus 2006. Pretax operating income of $1.06 billion in 2007 was 31% higher than 2006. Pretax operating margin reached 35.8%—an increase of 299 bps in 2007 versus 2006—demonstrating continued high vessel utilization, pricing increases in Marine and accelerating demand for exploration-driven seismic services. Q-Technology revenue reached $1.14 billion, representing 38% of 2007 full-year revenue.

Revenue backlog reached $1.2 billion at the end of 2007 compared to $1.1 million at the end of 2006.

Marine revenue grew 17% due mainly to strong activity in Asia, Middle East, India, Europe and North America as operators continued to focus on new exploration horizons. High vessel utilization, continued adoption of Q-Technology and improved pricing contributed to this performance.

Multiclient revenue increased 30% driven by higher sales in North America as the demand for E-Dog and E-Cat surveys remained strong during the first half of the year augmented by strong demand for E-Octopus surveys during the second half.

Data Processing revenue increased 26%, reflecting higher acquisition volumes, higher levels of Q processing, and higher activity in India, Asia, North Africa, Europe and the Caspian.

Land revenue increased 6% with the continued adoption of Q-Land* technology in Africa and in the Middle East.

During the second quarter of the year, the seventh Q-Technology equipped vessel—the Western Spirit—was launched. The eighth and ninth Q vessels will be launched, as previously announced, in 2008 and 2009, respectively.

As previously discussed, Schlumberger acquired Eastern Echo to meet demand for market-leading WesternGeco Q-Marine* seismic technology services.

Total Year 2006 Results

Operating revenue of $2.48 billion increased 49% in 2006 versus 2005. This strong performance was due to the continued market acceptance of Q-Technology* services and strong performance from Marine, Land, Data Processing and Multiclient services. During the second quarter, Schlumberger acquired the remaining Baker Hughes 30% minority interest in WesternGeco from Baker Hughes Incorporated.

Revenue backlog reached $1.1 billion at the end of 2006 compared to $790 million at the end of 2005, reflecting increasing exploration and production activity.

Q-Technology revenues reached $726 million in 2006, representing 29% of total revenue in 2006, significantly in excess of the $399 million revenue achieved in 2005. Utilization of the six Q-equipped vessels reached 100% in the fourth quarter of 2006.

Multiclient sales increased 51% to $770 million, mainly in the US Gulf of Mexico due to strong sales of the world’s largest and most complex depth migration project—known as E-Dog—which covers an area of 20,250 sq km and extends over 800 blocks in the deepwater Gulf of Mexico. Also contributing to the strong increase were higher sales in Latin America, Asia and West Africa—reflecting the strengthening exploration activity.

Marine revenue grew 65% due mainly to strong activity in Asia, Middle East, India, Europe and North America. Higher vessel utilization, accelerated adoption of Q-Technology and increasing prices contributed to this performance.

Land revenue increased 28% driven by higher sales of Q-Land, strong activity in the Middle East and South America, and a steep growth in North Africa.

25

Part II, Item 7 

Data Processing revenue increased 22%, reflecting higher acquisition volumes, higher levels of Q processing, and higher activity in India, Asia, North Africa, Europe and the Caspian. During the year, WesternGeco opened a new data processing and reservoir services center in Mumbai, India. The new center, staffed with more than 40 geologists and geophysicists, is one of the most powerful WesternGeco computing facilities worldwide. The center is equipped to provide customers with a full suite of advanced data processing services, including depth imaging and reservoir seismic services such as reservoir characterization and 4D (time-lapse) processing and analysis.

Pretax operating income reached $812 million in 2006 compared to $295 million in 2005 due to accelerating demand for Q technology coupled with improved pricing and increased vessel utilization, together with strong Multiclient sales.

Increased demand for Q-Marine services led to the commissioning of the sixth Q-Technology equipped vessel—the Western Monarch—during the second quarter. In addition, and in response to further demand, WesternGeco announced the launch of the seventh, eighth and ninth Q vessels in 2007, 2008 and 2009, respectively.

The average return on investments increased to 5.2% in 2007 from 4.5% in 2006 and the weighted average investment balance of $3.1 billion in 2007 increased $531 million compared to 2006.

The average return on investments increased to 4.5% in 2006 from 3.3% in 2005 and the weighted average investment balance of $2.6 billion in 2006 decreased $452 million compared to 2005.

Equity in Net Earnings of Affiliated Companies

The equity in net earnings of affiliated companies primarily represents Schlumberger’s share of the results of its 40% interest in the M-I SWACO drilling fluids joint venture with Smith International Inc.

Interest Expense

Interest expense of $275 million in 2007 increased by $40 million compared to 2006. The weighted average borrowing rates of 5.0% increased in 2007 from 4.6% in 2006. The weighted average debt balance of $5.5 billion in 2007 increased by $420 million compared to 2006, primarily due to the funding, in the second quarter of 2006, of the WesternGeco transaction described in Note 4 to theConsolidated Financial Statements.

26

Part II, Item 7 

Interest expense of $235 million in 2006 increased by $38 million compared to 2005. The weighted average borrowing rates of 4.6% increased in 2006 from 4.4% in 2005. The weighted average debt balance of $5.1 billion in 2006 increased by $609 million compared to 2005, primarily due to the funding, in the second quarter of 2006, of the WesternGeco transaction described in Note 4 to theConsolidated Financial Statements.

Other

Gross margin was 33.5%, 31.4% and 25.7% in 2007, 2006 and 2005, respectively. The increases in gross margins are primarily due to record activity levels in 2007 and 2006, increased pricing, stronger demand for higher-margin technologies, and operating efficiency improvements.

As a percentage of revenue, Research & engineering, Marketing and General & administrative expenses are as follows:

	2007		2006		2005
Research & engineering	3.1	%	3.2	%*	3.5	%
Marketing	0.4	%	0.4	%	0.4	%

2. Includes $16 million of cost in 2006 associated with Schlumberger’s relocation of its United States research center from Ridgefield to Boston.

Income Taxes

The reported effective tax rate, including Charges and Credits,was 21.9% in 2007, 24.0% in 2006 and 22.9% in 2005. The Charges and Credits noted below decreased the effective rate by 1.5% in 2005. The impact of Charges and Credits on the effective tax rate in 2007 and 2006 was not significant.

The decrease in the effective tax rate in 2007, as compared to 2006, was primarily attributable to the geographic mix of earnings. Both Oilfield Services and WesternGeco had a lower proportion of pretax earnings in North America. Outside North America, various GeoMarkets with lower tax rates contributed a greater percentage to pretax earnings.

The effective tax rate in 2005 reflects the impact of the $163 million gain on the sale of the Montrouge facility. This transaction allowed for the utilization of a deferred tax asset that was previously offset by a valuation allowance and had the effect of lowering the effective tax rate during 2005 by 1.3%. Excluding the impact of this transaction, the effective tax rate was relatively flat in 2006 as compared to 2005.

Charges and Credits

During each of 2007, 2006 and 2005, Schlumberger recorded significant charges and credits. These charges and credits, which are summarized below, are more fully described in Note 3 to theConsolidated Financial Statements.

Stock-based Compensation and Other

Stock-based compensation expense was $136 million in 2007 compared to $114 million in 2006 and $40 million in 2005.

The $22 million increase in stock-based compensation expense in 2007, as compared to 2006, was attributable to (i) the fact that Schlumberger began granting restricted stock in 2006 to a targeted population of employees in order to promote retention and the fair value of the restricted stock is expensed over the vesting period, which is generally three years and (ii) the impact of increased valuations of stock-based compensation awards due to the upward movement in Schlumberger’s stock price as compared to prior years.

The $74 million increase in stock-based compensation expense in 2006, as compared to 2005, was primarily attributable to (i) the impact of Schlumberger’s adoption of FAS 123R and FAS 123 as discussed in Note 14 to theConsolidated Financial Statements, (ii) valuations of stock-based compensation awards increasing due to the upward movement in Schlumberger’s stock price as compared to prior years and (iii) the impact of the implementation of the restricted stock program in 2006.

Stock-based compensation expense is currently estimated to be approximately $180 million in 2008. This represents an increase of $44 million as compared to 2007 and will be primarily attributable to increased valuations of stock-based compensation awards due to Schlumberger’s higher stock price in recent years as compared to prior years, as well as the continued effect of the restricted stock program.

During 2006, Schlumberger relocated its United States corporate office from New York to Houston and its United States research center from Ridgefield to Boston. Schlumberger incurred approximately $30 million of incremental expenses in connection with these moves in 2006. The vast majority of these costs were incurred in the third and fourth quarters of 2006 ($10 million in the third quarter; $15 million in the fourth quarter).

Key liquidity events during 2007, 2006 and 2005 included:

· On December 10, 2007, Schlumberger completed the acquisition of Eastern Echo for $838 million in cash. Net assets acquired included $320 million of cash and investments and $182 million of long-term debt.

· On April 28, 2006, Schlumberger acquired the remaining 30% minority interest in WesternGeco from Baker Hughes Incorporated for $2.4 billion in cash. Approximately 50% of the purchase price was funded from Schlumberger’s cash and investments. The remaining 50% was financed through existing Schlumberger credit facilities.

29

Part II, Item 7 

· In September 2006, Schlumberger Finance B.V. issued €400 million Guaranteed Floating Rate Notes due 2009. Interest is payable quarterly at the rate of 10 basis points over 3-month Euribor. Schlumberger entered into an agreement to swap these Euro notes for US dollars on the date of issue until maturity, effectively making this US dollar denominated debt on which Schlumberger Finance B.V. will pay interest in US dollars at the rate of 3-month LIBOR plus 0.0875%. The proceeds from these notes were used to repay commercial paper borrowings.

· On July 22, 2004, the Board of Directors of Schlumberger approved a share repurchase program of up to 30 million shares of common stock to be acquired in the open market before December 2006, subject to market conditions. This program was completed during the first quarter of 2006. On April 20, 2006, the Board of Directors of Schlumberger approved another share repurchase program of up to 40 million shares of common stock to be acquired in the open market before April 2010, subject to market conditions, of which approximately 29.9 million shares of common stock have been repurchased as of December 31, 2007. The following table summarizes the activity under these share repurchase programs during 2007, 2006 and 2005:

(Stated in thousands except per share amounts and prices)
	Total cost of shares purchased		Total number of shares purchased	Average price paid per share
2007	$	1,355,000	16,336.1	$	82.95
2006	$	1,067,842	17,992.7	$	59.35
2005	$	611,641	15,274.8	$	40.04

· During 2007, 2006 and 2005, Schlumberger announced that its Board of Directors had approved increases in the quarterly dividend of 40%, 19% and 12%, respectively. On January 18, 2008, Schlumberger announced that its Board of Directors approved a 20% increase in the quarterly dividend to $0.21 per share effective commencing with the dividend payable on April 4, 2008. Total dividends paid during 2007, 2006 and 2005 were approximately $771 million, $568 million and $482 million, respectively.

· Cash flow provided by operations was $6.3 billion in 2007, $4.8 billion in 2006 and $3.0 billion in 2005. These improvements were driven by the significant revenue and net income increases experienced in 2007 and 2006.

· Capital expenditures, including multiclient seismic data costs, were $3.2 billion in 2007, $2.6 billion in 2006 and $1.7 billion in 2005. These increases were a result of the increased activity levels experienced in recent years. Capital expenditures, including multiclient seismic data costs, are expected to approach $4.2 billion in 2008.

Schlumberger believes that at December 31, 2007, cash and short-term investments of $3.2 billion and available and unused credit facilities of $2.3 billion were sufficient to meet future business requirements for at least the next twelve months.

1. Excludes future payments for interest. Includes amounts relating to the $769 million of Convertible Debentures which are described in Note 11 of theConsolidated Financial Statements.

2. Represents an estimate of contractual obligations in the ordinary course of business. Although these contractual obligations are considered enforceable and legally binding, the terms generally allow Schlumberger the option to reschedule and adjust their requirements based on business needs prior to the delivery of goods.

Refer to Note 19 of theConsolidated Financial Statements for details regarding Schlumberger’s pension and other postretirement benefit obligations.

As discussed in Note 15 of theConsolidated Financial Statements, included in the SchlumbergerConsolidated Balance Sheet at December 31, 2007 is approximately $858 million of liabilities associated with uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business. Due to the uncertain and complex application of tax regulations, combined with the difficulty in predicting when tax audits throughout the world may be concluded, Schlumberger cannot make reliable estimates of the timing of cash outflows relating to these liabilities.

Schlumberger has outstanding letters of credit/guarantees which relate to business performance bonds, custom/excise tax commitments, facility lease/rental obligations, etc. These were entered into in the ordinary course of business and are customary practices in the various countries where Schlumberger operates.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires Schlumberger to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. The following accounting policies involve “critical accounting estimates” because they are particularly dependent on estimates and assumptions made by Schlumberger about matters that are inherently uncertain. A summary of all of Schlumberger’s significant accounting policies is included in Note 2 to theConsolidated Financial Statements.

Schlumberger bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Multiclient Seismic Data

The WesternGeco segment capitalizes the costs associated with obtaining multiclient seismic data. The carrying value of the multiclient seismic data library at December 31, 2007, 2006 and 2005 was $182 million, $227 million and $222 million, respectively. Such costs are charged toCost of goods sold and services based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data. However, except as described below under “WesternGeco Purchase Accounting,” under no circumstances will an individual survey carry a net book value greater than a 4-year straight-line amortized value.

31

Part II, Item 7 

The carrying value of surveys is reviewed for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Adjustments to the carrying value are recorded when it is determined that estimated future revenues, which involve significant judgment on the part of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period. For purposes of performing the annual impairment test of the multiclient library, future cash flows are analyzed based on two pools of surveys: United States and non-United States. The United States and non-United States pools were determined to be the most appropriate level at which to perform the impairment review based upon a number of factors including (i) various macroeconomic factors that influence the ability to successfully market surveys and (ii) the focus of the sales force and related costs.

WesternGeco Purchase Accounting

As described in Note 4 to theConsolidated Financial Statements, on April 28, 2006, Schlumberger acquired the remaining 30% minority interest in WesternGeco from Baker Hughes Incorporated for $2.4 billion in cash. As a result of this transaction, Schlumberger attained 100% ownership of WesternGeco.

During the process of allocating the purchase price to the proportionate share of net assets acquired based upon their estimated fair values, Schlumberger made certain significant estimates and assumptions relating to the accounting for WesternGeco’s vessels and multiclient seismic data.

In analyzing the fair value of the WesternGeco vessels, it was determined that the remaining estimated useful lives of these assets exceeded the remaining estimated life currently being used to calculate depreciation expense. Therefore, the estimated remaining useful lives of the vessels were extended an additional 4 years (on a weighted average basis) as of the date of the acquisition. The impact of the fair value adjustments for all fixed assets, combined with the change in estimate regarding the depreciable lives of the vessels, resulted in a net reduction in depreciation expense of approximately $2 million in 2006.

The carrying value of the multiclient library immediately after the acquisition increased to $243 million from $202 million, reflecting the impact of a $41 million fair value adjustment. These capitalized costs are being charged toCost of goods sold and services based on the percentage of the total costs on the balance sheet to the estimated total revenue that Schlumberger expects to receive from the sales of such data. Schlumberger’s policy has been that under no circumstance will an individual survey carry a net book value greater than a 4-year straight-line amortized value. After consideration of the estimated number of future years that revenues are expected to be derived from the multiclient seismic data at the time of the acquisition, Schlumberger concluded that the remaining minimum amortization period should be 3 years for all surveys in the multiclient seismic library at the time of the transaction, effectively resetting the minimum amortization period. Therefore, the $243 million of capitalized multiclient seismic data costs will be charged to expense over a period no longer than the next 3 years from the date of the transaction. Surveys comprising the $202 million of multiclient seismic data costs prior to this transaction had a weighted average remaining life for purposes of computing the minimum amortization of approximately 1.8 years. Given the current emphasis on requiring multiclient projects to be significantly prefunded before a project commences, Schlumberger currently estimates that the majority of revenues to be derived from sales of new surveys will be achieved within a 4-year period. Therefore, Schlumberger will continue its policy that under no circumstance will an individual survey carry a net book value greater than a 4-year straight-line amortized value for all surveys added to the library after the date of this transaction.

The net impact of the $41 million fair value adjustment combined with the resetting of the minimum amortization period resulted in an approximate $28 million net reduction in multiclient amortization expense in 2006 as compared to what multiclient amortization expense would have been had this transaction not been consummated.

Part II, Item 7 

Allowance for Doubtful Accounts

Schlumberger maintains an allowance for doubtful accounts in order to record accounts receivable at their net realizable value. A significant amount of judgment is involved in recording and making adjustments to this reserve. Allowances have been recorded for receivables believed to be uncollectible, including amounts for the resolution of potential credit and other collection issues such as disputed invoices, customer satisfaction claims and pricing discrepancies. Depending on how such potential issues are resolved, or if the financial condition of Schlumberger’s customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.

Goodwill, Intangible Assets and Long-Lived Assets

Schlumberger records as goodwill the excess of purchase price over the fair value of the tangible and identifiable intangible assets acquired. Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS 142), requires goodwill to be tested for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Goodwill is tested for impairment by comparing the fair value of Schlumberger’s individual reporting units to their carrying amount to determine if there is a potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value.

For purposes of performing the impairment test for goodwill as required by SFAS 142, Schlumberger’s reporting units are primarily the geographic areas comprising the Oilfield Services segment in addition to the WesternGeco segment. Schlumberger estimates the fair value of these reporting units using a discounted cash flow analysis and/or applying various market multiples. From time to time a third-party valuation expert may assist in the determination of fair value. Determining the fair value of a reporting unit is a matter of judgment and often involves the use of significant estimates and assumptions. Schlumberger’s estimates of the fair value of each of its reporting units were significantly in excess of their respective carrying values at the time of the annual goodwill impairment tests for 2007, 2006 and 2005.

Long-lived assets, including fixed assets and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. In order to estimate the fair value of a long-lived asset, Schlumberger may engage a third-party to assist with the valuation. If there is a material change in economic conditions or other circumstances influencing the estimate of future cash flows or fair value, Schlumberger could be required to recognize impairment charges in the future. Schlumberger evaluates the remaining useful life of its intangible assets on a periodic basis to determine whether events and circumstances warrant a revision to the remaining estimated amortization period.

Part II, Item 7 

Income Taxes

Schlumberger’s tax filings are subject to regular audit by the tax authorities in most of the over 100 jurisdictions in which it conducts business. These audits may result in assessments for additional taxes which are resolved with the authorities or, potentially, through the courts. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. In such an event, Schlumberger will record additional tax expense or tax benefit in the period in which such resolution occurs.

Pension and Postretirement Benefits

Schlumberger’s pension benefit and postretirement medical benefit obligations and related costs are calculated using actuarial concepts, which include critical assumptions related to the discount rate, expected return on plan assets and medical cost trend rates. These assumptions are important elements of expense and/or liability measurement and are updated on an annual basis at the beginning of each fiscal year, or more frequently upon the occurrence of significant events.

The discount rate Schlumberger uses reflects the prevailing market rate of a portfolio of high-quality debt instruments with maturities matching the expected timing of the payment of the benefit obligations. The discount rate utilized to determine both the liability for Schlumberger’s United States pension plans and for Schlumberger’s United States postretirement medical plans was increased from 6.00% at December 31, 2006 to 6.50% at December 31, 2007. The discount rate utilized to determine expense for Schlumberger’s United States pension plans and postretirement medical plans was increased from 5.75% in 2006 to 6.00% in 2007. The change in the discount rate was made to reflect market interest rate conditions. A higher discount rate decreases the present value of benefit obligations and decreases expense.

The expected rate of return for our retirement benefit plans represents the average rate of return expected to be earned on plan assets over the period that benefits included in the benefit obligation, are expected to be paid. The expected rate of return for Schlumberger’s United States pension plans has been determined based upon expectations regarding future rates of return for the investment portfolio, with consideration given to the distribution of investments by asset class and historical rates of return for each individual asset class. The expected rate of return on plan assets was 8.50% in 2007 and 2006. A lower expected rate of return would increase pension expense.

Schlumberger’s medical cost trend rate assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. The overall medical cost trend rate assumption utilized in both 2007 and 2006 was 9% graded to 6% over the next four years and 5% thereafter.

The following illustrates the sensitivity to changes in certain assumptions, holding all other assumptions constant, for the United States pension plans:

(Stated in millions)
Change in Assumption	Effect on 2007 Pretax Pension Expense		Effect on Dec. 31, 2007 Liability

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk.

Schlumberger is subject to market risk primarily associated with changes in foreign currency exchange rates and interest rates.

As a multinational company, Schlumberger conducts its business in approximately 80 countries. Schlumberger’s functional currency is primarily the US dollar, which is consistent with the oil and gas industry. Approximately 83% of Schlumberger’s revenue in 2007 was denominated in US dollars. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies. Therefore, when the US dollar weakens in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar-reported expenses will increase.

A 5% change in the average exchange rates of all the foreign currencies in 2007 would have changed revenue by approximately 1%. If the 2007 average exchange rates of the US dollar against all foreign currencies had strengthened by 5%, Schlumberger’s income from continuing operations would have increased by 3%. Conversely, a 5% weakening of the US dollar average exchange rates would have decreased income from continuing operations by 3%.

Schlumberger maintains a foreign-currency risk management strategy that uses derivative instruments to protect its interests from unanticipated fluctuations in earnings and cash flows caused by volatility in currency exchange rates. Foreign currency forward contracts provide a hedge against currency fluctuations either on assets/liabilities denominated in other than a functional currency or on expenses.

At December 31, 2007, contracts were outstanding for the US dollar equivalent of $2.6 billion in various foreign currencies. These contracts mature on various dates in 2008.

Schlumberger is subject to interest rate risk on its debt. Schlumberger maintains an interest rate risk management strategy that uses a mix of variable- and fixed-rate debt together with interest rate swaps, where appropriate, to fix or lower borrowing costs.

At December 31, 2007, Schlumberger had fixed rate debt aggregating approximately $2.6 billion and variable rate debt aggregating approximately $2.9 billion.

Schlumberger’s exposure to interest rate risk associated with its debt is also somewhat mitigated by its investment portfolio. BothShort-term investments andFixed income investments, held to maturity, which totaled approximately $3.4 billion at December 31, 2007, are comprised primarily of eurodollar time deposits, certificates of deposit and commercial paper, euronotes and eurobonds, and are substantially all denominated in US dollars. The average return on investment was 5.2% in 2007.

Total	$	1,672	$	605	$	936	$	736	$	1,495	$	5,444

The fair market value of the outstanding fixed rate debt was approximately $3.9 billion as of December 31, 2007. The weighted average interest rate on the variable rate debt as of December 31, 2007 was approximately 5.3%.

On December 31, 2007, interest rate swap arrangements outstanding were pay floating/receive fixed on US dollar debt of $40 million. These arrangements mature at various dates to December 2009. Interest rate swap arrangements decreased consolidated interest expense in 2007 by $0.4 million.

Schlumberger does not enter into foreign currency or interest rate derivatives for speculative purposes.

Notes to Consolidated Financial Statements

1.    Business Description

Schlumberger Limited (Schlumberger N.V., incorporated in the Netherlands Antilles) and its subsidiaries form the world’s leading oilfield services company, supplying technology, project management, and information solutions that optimize performance in the oil and gas industry. Schlumberger consists of two business segments: Oilfield Services (“OFS”) and WesternGeco. Oilfield Services is the world’s premier oilfield service company, supplying a wide range of technology services and solutions to the international petroleum industry. The Oilfield Services segment provides virtually all exploration and production services required during the life of an oil and gas reservoir. WesternGeco provides comprehensive worldwide reservoir imaging, monitoring, and development services, with extensive seismic crews and data processing centers as well as a large multiclient seismic library. Services range from 3D and time-lapse (4D) seismic surveys to multi-component surveys for delineating prospects and reservoir management.

2.    Summary of Accounting Policies

TheConsolidated Financial Statements of Schlumberger Limited (“Schlumberger”) have been prepared in accordance with accounting principles generally accepted in the United States of America.

Principles of Consolidation

The accompanyingConsolidated Financial Statements include the accounts of Schlumberger, its wholly owned subsidiaries, and subsidiaries over which it exercises a controlling financial interest. All significant intercompany transactions and balances have been eliminated. Investments in entities in which Schlumberger does not have a controlling financial interest, but over which it has significant influence are accounted for using the equity method. Schlumberger’s share of the after-tax earnings of equity method investees is included inInterest and other income. Investments in which Schlumberger does not have the ability to exercise significant influence are accounted for using the cost method. Both equity and cost method investments are classified inInvestments in Affiliated Companies.

Reclassifications

Certain items from prior years have been reclassified to conform to the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable, valuation of inventories and investments, recoverability of goodwill and intangible assets, income taxes, multiclient seismic data, contingencies and actuarial assumptions for employee benefit plans. Schlumberger bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

43

Part II, Item 8 

Revenue Recognition

Oilfield Services

Services and Products Revenue

Schlumberger recognizes revenue for services and products based upon purchase orders, contracts or other persuasive evidence of an arrangement with the customer that include fixed or determinable prices. Revenue is recognized for services when they are rendered and collectibility is reasonably assured. Revenue is recognized for products upon delivery, customer acceptance and when collectibility is reasonably assured.

Software Revenue

Revenue derived from the sale of licenses of Schlumberger software may include installation, maintenance, consulting and training services.

If services are not essential to the functionality of the software, the revenue for each element of the contract is recognized separately based on its respective vendor specific objective evidence of fair value when all of the following conditions are met: a signed contract is obtained, delivery has occurred, the fee is fixed or determinable and collectibility is probable.

If an ongoing vendor obligation exists under the license arrangement, or if any uncertainties with regard to customer acceptance are significant, revenue for the related element is deferred based on its vendor specific objective evidence of fair value. Vendor specific objective evidence of fair value is determined as being the price for the element when sold separately. If vendor specific objective evidence of fair value does not exist for all undelivered elements, all revenue is deferred until sufficient evidence exists or all elements have been delivered.

The percentage of completion method of accounting is applied to contracts whereby software is being customized to a customer’s specifications.

WesternGeco

Revenue from all services is recognized when persuasive evidence of an arrangement exists, the price is fixed or determinable and collectibility is reasonably assured. Revenue from contract services performed on a dayrate basis is recognized as the service is performed. Revenue from other contract services, including pre-funded multiclient surveys, is recognized as the seismic data is acquired and/or processed on a proportionate basis as work is performed. This method requires revenue to be recognized based upon quantifiable measures of progress, such as square kilometers acquired. Multiclient data surveys are licensed or sold to customers on a non-transferable basis. Revenue on completed multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers access to such data.

Multiple Deliverable Arrangements

Revenue in both segments may be generated from contractual arrangements that include multiple deliverables, including certain Integrated Project Management contracts. Revenue from these arrangements is recognized as each item is delivered based on their relative fair value and when the delivered items have stand-alone value to the customer.

Other

Taxes assessed by governmental authorities that are imposed concurrently on specific revenue-producing transaction, such as sales and value added taxes, are excluded from revenue in theConsolidated Statement of Income.

44

Part II, Item 8 

Translation of Non-United States Currencies

Schlumberger’s functional currency is primarily the US dollar. All assets and liabilities recorded in functional currencies other than US dollars are translated at current exchange rates. The resulting adjustments are charged or credited directly to theStockholders’ Equity section of theConsolidated Balance Sheet. Revenue and expenses are translated at the weighted-average exchange rates for the period. All realized and unrealized transaction gains and losses are included in income in the period in which they occur. Transaction losses of $17 million, $20 million, and $13 million were recognized in 2007, 2006 and 2005, respectively.

Investments

TheConsolidated Balance Sheet reflects the Schlumberger investment portfolio separated between current and long term, based on maturity. Under normal circumstances it is the intent of Schlumberger to hold the investments until maturity, with the exception of investments that are considered trading (December 31, 2007—$184 million; December 31, 2006—$164 million). BothShort-term investments andFixed Income Investments, held to maturity are comprised primarily of money market funds, eurodollar time deposits, certificates of deposit and commercial paper, euronotes and eurobonds, and are substantially denominated in US dollars. They are stated at cost plus accrued interest, which approximates market. Short-term investments that are designated as trading are stated at market. The unrealized gains/losses on investments designated as trading were not significant at both December 31, 2007 and 2006.

For purposes of theConsolidated Statement of Cash Flows, Schlumberger does not consider short-term investments to be cash equivalents as a significant portion of them have original maturities in excess of three months.

Long-term fixed income investments of $440 million mature as follows: $152 million in 2009, $81 million in 2010, $84 million in 2011 and $123 million in 2012.

Inventories

Inventories are stated at average cost or at market, whichever is lower. Inventory consists of materials, supplies and finished goods. Costs included in inventories consist of materials, direct labor and manufacturing overhead.

Fixed Assets and Depreciation

Fixed assets are stated at cost less accumulated depreciation, which is provided for by charges to income over the estimated useful lives of the assets using the straight-line method. Fixed assets include the manufacturing cost of oilfield technical equipment manufactured or assembled by subsidiaries of Schlumberger. Expenditures for replacements and improvements are capitalized. Maintenance and repairs are charged to operating expenses as incurred. Upon sale or other disposition, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposal, is charged or credited to income.

Multiclient Seismic Data

The multiclient library consists of completed and in-process seismic surveys that are licensed on a nonexclusive basis. This data may be acquired and/or processed by Schlumberger or subcontractors. Multiclient surveys are primarily generated utilizing Schlumberger resources. Schlumberger capitalizes costs directly incurred in acquiring and processing the multiclient seismic data. Such costs are charged toCost of goods sold and services based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data. However, except as described in Note 4Acquisitions regarding the accounting for multiclient seismic data at the time of the purchase of the WesternGeco minority interest, under no circumstance will an individual survey carry a net book value greater than a 4- year straight-line amortized value.

45

Part II, Item 8 

The carrying value of the multiclient library is reviewed for impairment annually as well as when an event or change in circumstance indicating impairment may have occurred. Adjustments to the carrying value are recorded when it is determined that estimated future cash flows, which involves significant judgment on the part of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period.

Goodwill, Other Intangibles and Long-lived Assets

Schlumberger records as goodwill the excess of purchase price over the fair value of the tangible and identifiable intangible assets acquired. Statement of Financial Accounting Standards 142,Goodwill and Other Intangible Assets (SFAS 142), requires goodwill to be tested for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Goodwill is tested for impairment by comparing the fair value of Schlumberger’s individual reporting units to their carrying amount to determine if there is a potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value.

For purposes of performing the impairment test for goodwill as required by SFAS 142, Schlumberger’s reporting units are primarily the geographic areas comprising the Oilfield Services segment in addition to the WesternGeco segment. Schlumberger estimates the fair value of these reporting units using a discounted cash flow analysis and/or applying various market multiples. From time to time a third-party valuation expert may be utilized to assist in the determination of fair value. Determining the fair value of a reporting unit is a matter of judgment and often involves the use of significant estimates and assumptions. Schlumberger’s estimates of the fair value of each of its reporting units were significantly in excess of their respective carrying values for 2007, 2006 and 2005. Schlumberger performs the annual goodwill impairment test of its WesternGeco reporting unit on October 1^st of every year while the reporting units comprising the Oilfield Services segment are tested as of December 31^st.

Long-lived assets, including fixed assets and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involve significant estimates on the part of management. In order to estimate the fair value of a long-lived asset, Schlumberger may engage a third-party to assist with the valuation. If there is a material change in economic conditions or other circumstances influencing the estimate of future cash flows or fair value, Schlumberger could be required to recognize impairment charges in the future.

Schlumberger capitalizes certain costs of internally developed software. Capitalized costs include purchased materials and services, payroll and payroll related costs. The costs of internally developed software are amortized on a straight-line basis over the estimated useful life, which is principally 5 to 7 years. Other intangible assets consist primarily of technology and customer relationships acquired in business combinations. Acquired technology is generally amortized over periods ranging from 5 to 15 years and acquired customer relationships are generally amortized over periods ranging from 7 years to 20 years.

46

Part II, Item 8 

Taxes on Income

Schlumberger and its subsidiaries compute taxes on income in accordance with the tax rules and regulations of the many taxing authorities where the income is earned. The income tax rates imposed by these taxing authorities vary substantially. Taxable income may differ from pretax income for financial accounting purposes. To the extent that differences are due to revenue or expense items reported in one period for tax purposes and in another period for financial accounting purposes, an appropriate provision for deferred income taxes is made. Any effect of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. When it is more likely than not that a portion or all of the deferred tax asset will not be realized in the future, Schlumberger provides a corresponding valuation allowance against deferred tax assets.

Schlumberger’s tax filings are subject to regular audit by the tax authorities in most of the jurisdictions in which it conducts business. These audits may result in assessments for additional taxes which are resolved with the authorities or, potentially, through the courts. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulation, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. In such an event, Schlumberger will record additional tax expense or tax benefit in the year in which such resolution occurs.

Approximately $12.6 billion of consolidated income retained for use in the business on December 31, 2007 represented undistributed earnings of consolidated subsidiaries and Schlumberger’s share of equity method investees. No provision is made for deferred income taxes on those earnings considered to be indefinitely reinvested or earnings that would not be taxed when remitted.

Concentration of Credit Risk

Schlumberger’s assets that are exposed to concentrations of credit risk consist primarily of cash, short-term investments, fixed income investments held to maturity, and receivables from clients and derivative financial instruments. Schlumberger places its cash, short-term investments and fixed income investments held to maturity with financial institutions and corporations, and limits the amount of credit exposure with any one of them. Schlumberger regularly evaluates the creditworthiness of the issuers in which it invests. The receivables from clients are spread over many countries and customers. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectibility and performs ongoing credit evaluations of its customers’ financial condition. By using derivative financial instruments to hedge exposure to changes in exchange rates and interest rates, Schlumberger exposes itself to credit risk. Schlumberger minimizes the credit risk by entering into transactions with high-quality counterparties, limiting the exposure to each counterparty and monitoring the financial condition of its counterparties.

Research & Engineering

All research and engineering expenditures are expensed as incurred, including costs relating to patents or rights that may result from such expenditures.

47

Part II, Item 8 

Earnings per Share

Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings per share is calculated by first adding back to net income the interest expense on the convertible debentures and then dividing this adjusted net income by the sum of (i) unvested restricted stock units; and (ii) the weighted average number of common shares outstanding assuming dilution. The weighted average number of common shares outstanding assuming dilution assumes (a) that all stock options which are in the money are exercised at the beginning of the period and that the proceeds are used by Schlumberger to purchase shares at the average market price for the period, and (b) the conversion of the convertible debentures.

If the impact of adding the interest expense on the convertible debentures back to net income and including the shares from the assumed conversion of the convertible debentures has an anti-dilutive effect on the diluted earnings per share calculation, then the effects of the convertible debentures are excluded from the calculation.

The following is a reconciliation from basic earnings per share to diluted earnings per share from continuing operations for each of the last three years:

(Stated in thousands except per share amounts)
	Income from Continuing Operations		Weighted Average Shares Outstanding	Earnings Per Share from Continuing Operations
2007:
Basic	$	5,176,516	1,187,944	$	4.36
Assumed conversion of debentures		23,671	28,986
Assumed exercise of stock options		–	20,868
Unvested restricted stock		–	877
Diluted	$	5,200,187	1,238,675	$	4.20
2006:
Basic	$	3,709,851	1,181,683	$	3.14
Assumed conversion of debentures		28,788	38,210
Assumed exercise of stock options		–	21,874
Unvested restricted stock		–	429
Diluted	$	3,738,639	1,242,196	$	3.01
2005:
Basic	$	2,198,995	1,178,576	$	1.87
Assumed conversion of debentures		28,788	38,210
Assumed exercise of stock options		–	12,930
Diluted	$	2,227,783	1,229,716	$	1.81

Employee stock options to purchase approximately 809,500 and 628,000 shares of common stock at December 31, 2007 and 2006, respectively, were outstanding but not included in the computation of diluted earnings per share because the option exercise price was greater than the average market price of the common stock, and therefore, the effect on diluted earnings per share would have been anti-dilutive. At December 31, 2005 the average market price was greater than the exercise price of all outstanding stock options, therefore there were no options excluded from the computation of diluted earnings per share for 2005.

48

Part II, Item 8 

Recently Issued Accounting Pronouncements

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS 141 (revised 2007),Business Combinations (“SFAS 141(R)”). SFAS 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed, and any noncontrolling interest (previously referred to as minority interest) in the acquiree. The provisions of SFAS 141(R) are effective for business combinations occurring on or after January 1, 2009.

In December 2007, the FASB issued SFAS 160,Noncontrolling Interests in Consolidated Financial Statements, an Amendment of ARB No. 51(“SFAS 160”). This statement amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the loss of control of a subsidiary. Upon its adoption on January 1, 2009, noncontrolling interests will be classified as equity in the Schlumberger financial statements.

SFAS 160 also changes the way the consolidated income statement is presented by requiring net income to include the net income for both the parent and the noncontrolling interest, with disclosure of both amounts on the consolidated statement of income. The calculation of earnings per share will continue to be based on income amounts attributable to the parent. The provisions of this standard must be applied retrospectively upon adoption.

3.    Charges and Credits

Schlumberger recorded the following Charges and Credits in 2007, 2006 and 2005:

2007

Fourth quarter of 2007:

· Schlumberger sold certain workover rigs for $32 million, resulting in a pretax gain of $25 million ($17 million after-tax) which is classified inInterest and other income in theConsolidated Statement of Income.

2006

Second quarter of 2006:

· As discussed in further detail in Note 4 Acquisitions, Schlumberger acquired the remaining 30% minority interest in WesternGeco held by Baker Hughes Incorporated for $2.4 billion in cash during the second quarter of 2006. In connection with this transaction, a pretax and after-tax charge of $21 million was recorded, representing the portion of the purchase price that was allocated to in-process research and development. Schlumberger recorded an additional $6 million of in-process research and development charges, primarily related to a small acquisition which was also completed in the second quarter of 2006. These amounts were determined by identifying research and development projects that had not yet reached technological feasibility at the time of the acquisition. These charges are classified inResearch & engineering in theConsolidated Statement of Income.

· Schlumberger recorded a pretax and after-tax loss of $9 million relating to the liquidation of certain investments in connection with the funding of the previously mentioned WesternGeco transaction. These losses are classified inInterest and other income in theConsolidated Statement of Income.

· In connection with the settlement of the WesternGeco visa matter described in Note 17Contingencies, a pretax charge of $10 million ($7 million after-tax and minority interest) was recorded in the second quarter of 2006 and is classified inCost of goods sold and services in theConsolidated Statement of Income.

Third quarter of 2005:

Schlumberger recorded a pretax and after-tax gain of approximately $18 million relating to the resolution of a contingency associated with the March 2005 sale of its facility in Montrouge, France. This gain is classified inInterest and other income in theConsolidated Statement of Income.

First quarter of 2005:

In March 2005, Schlumberger sold its facility in Montrouge, France for $230 million, resulting in a pretax and after-tax gain of $146 million, which is classified inInterest and other income in theConsolidated Statement of Income. Schlumberger also recorded other real estate related pretax charges of $12 million ($11 million after-tax), which are classified inCost of goods sold and services in theConsolidated Statement of Income.

4.    Acquisitions

Acquisition of Eastern Echo Holding Plc

On December 10, 2007, Schlumberger completed the acquisition of Eastern Echo Holding Plc (“Eastern Echo”) for $838 million in cash. Eastern Echo is a Dubai-based marine seismic company that does not currently have any operations, but has signed contracts for the construction of six seismic vessels. The first four vessels are scheduled to be delivered in January, March, May and July of 2009, while the remaining two are scheduled to be delivered January and March of 2010.

50

Part II, Item 8 

The purchase price has been allocated to the net assets acquired based upon their estimated fair values as follows:

(Stated in millions)
Cash and short-term investments	$	266
Other current assets		23
Fixed income investments, held to maturity		54
Vessels under construction		735
Accounts payable and accrued liabilities		(17	)
Long-term debt		(182	)
Deferred tax liability		(41	)
Total purchase price	$	838

Acquisition of WesternGeco Minority Interest

On April 28, 2006, Schlumberger acquired the remaining 30% minority interest in WesternGeco from Baker Hughes Incorporated for $2.4 billion in cash. Schlumberger also incurred direct acquisition costs of $6 million in connection with this transaction. As a result of this transaction, Schlumberger owns 100% of WesternGeco.

The purchase price has been allocated to the proportionate share of net assets acquired based upon their estimated fair values as follows:

(Stated in millions)
Book value of minority interest acquired	$	460
Fair value adjustments:
Technology (weighted average life of 15 years)		293
Customer relationships (life of 20 years)		153
Vessels (weighted average remaining life of 11 years)		84
Other fixed assets (weighted average remaining life of 3 years)		10
Multiclient seismic data (maximum life of 3 years)		41
Other identifiable intangible assets (life of 15 years)		49
In-process research and development (expensed immediately – see Note 3)		21
Deferred income taxes		(43	)
Goodwill		1,338
Total purchase price	$	2,406

The amount allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired. Approximately $0.8 billion of the $1.3 billion of goodwill is estimated to be tax deductible. In addition, approximately $650 million of the goodwill created as a result of this transaction has been allocated to the Oilfield Services business segment in recognition of the estimated present value of future synergies paid for in this transaction that will directly benefit that segment.

Vessels and other fixed assets

In analyzing the fair value of the WesternGeco vessels, it was determined that the remaining estimated useful lives of these assets exceeded the remaining estimated life currently being used to calculate depreciation expense. Therefore, the estimated remaining useful lives of the vessels were extended an additional 4 years (on a weighted average basis) as of the date of the acquisition. The impact of the fair value adjustments for all fixed assets, combined with the change in estimate regarding the depreciable lives of the vessels, resulted in a net reduction in depreciation expense of approximately $2 million in 2006.

51

Part II, Item 8 

Multiclient seismic data

The carrying value of the multiclient library immediately after the acquisition increased to $243 million from $202 million, reflecting the impact of the $41 million fair value adjustment. These capitalized costs will be charged toCost of goods sold and services based on the percentage of the total costs on the balance sheet to the estimated total revenue that Schlumberger expects to receive from the sales of such data. Schlumberger policy has been that under no circumstance will an individual survey carry a net book value greater than a 4-year straight-line amortized value. After consideration of the estimated number of future years that revenues are expected to be derived from the multiclient seismic data at the time of the acquisition, Schlumberger concluded that the remaining minimum amortization period should be 3 years for all surveys in the multiclient seismic library at the time of the transaction, effectively resetting the minimum amortization period. Therefore, the $243 million of capitalized multiclient seismic data costs will be charged to expense over a period no longer than the next 3 years from the date of the transaction. Surveys comprising the $202 million of multiclient seismic data costs prior to this transaction had a weighted average remaining life for purposes of computing the minimum amortization of approximately 1.8 years. Given the current emphasis on requiring multiclient projects to be significantly prefunded before the project commences, Schlumberger currently estimates that the majority of revenues to be derived from sales of new surveys will be achieved within a 4-year period. Therefore, Schlumberger will continue its policy that under no circumstance will an individual survey carry a net book value greater than a 4-year straight-line amortized value for all surveys added to the library after the date of this transaction.

The net impact of the $41 million fair value adjustment combined with the resetting of the minimum amortization period resulted in an approximate $28 million net reduction in multiclient amortization expense in 2006 as compared to what multiclient amortization expense would have been had this transaction not been consummated.

Acquisition of PetroAlliance Minority Interest

On December 9, 2003, Schlumberger announced that it had signed an agreement to acquire PetroAlliance Services Company Limited (“PetroAlliance Services”) over a 3-year period based on a formula determined at that time. Schlumberger acquired 26% of PetroAlliance Services in the second quarter of 2004 for $12 million in cash and 843,740 shares of Schlumberger common stock valued at $24 million. During the second quarter of 2005, Schlumberger acquired an additional 25% of PetroAlliance Services for $40 million in cash and 2,300,646 shares of Schlumberger common stock valued at $79 million bringing its total ownership interest to 51%. During the second quarter of 2006, Schlumberger acquired the remaining 49% of PetroAlliance Services that it did not own for $165 million in cash and 4,730,960 shares of Schlumberger common stock valued at approximately $330 million. The aggregate purchase price paid for PetroAlliance Services over the 3-year period was $650 million.

Schlumberger began consolidating the results of PetroAlliance Services in the second quarter of 2005. This investment had previously been accounted under the equity method.

The $495 million purchase price paid in the second quarter of 2006 has been allocated to the proportionate share of net assets acquired based upon their estimated fair values as follows:

(Stated in millions)
Book value of minority interest acquired	$	33
Fair value adjustments:
Customer relationships (life of 12 years)		69
Other identifiable intangible assets (life of 5 years)		7
Deferred income taxes		(18	)
Goodwill		404
Total purchase price	$	495

52

Part II, Item 8 

The amount allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired. The goodwill is not tax deductible.

Other Acquisitions

Schlumberger has made other acquisitions and minority interest investments, none of which were significant on an individual basis, for cash payments of $306 million during 2007, $356 million during 2006, and $56 million during 2005.

Under the terms of certain past acquisitions, Schlumberger had obligations to pay additional consideration if specific conditions were met. Schlumberger made cash payments of $63 million during 2006 and $21 million during 2005, with respect to certain transactions that were consummated in prior years, which were recorded as additional goodwill.

Pro forma results pertaining to the above acquisitions, including the WesternGeco and PetroAlliance Services transactions, are not presented as the impact was not significant.

5.    Investments in Affiliated Companies

The MI-SWACO drilling fluids joint venture is owned 40% by Schlumberger and 60% by Smith International, Inc. Schlumberger records income relating to this venture using the equity method of accounting. Schlumberger’s investment in the joint venture on December 31, 2007 and 2006 was $1.2 billion and $970 million, respectively. Schlumberger’s equity income from this joint venture in 2007 was $174 million, $135 million in 2006 and $83 million in 2005. Schlumberger received cash distributions from the joint venture of $40 million in 2007 and $28 million in 2005. There were no such distributions in 2006.

Schlumberger’s joint venture agreement with Smith International, Inc. contains a provision under which either party to the joint venture may offer to sell its entire interest in the venture to the other party at a cash purchase price per percentage interest specified in an offer notice. If the offer to sell is not accepted, the offering party will be obligated to purchase the entire interest of the other party at the same price per percentage interest as the prices specified in the offer notice.

Intangible assets principally comprise software, technology and customer relationships. At December 31, the gross book value and accumulated amortization of intangible assets were as follows:

(Stated in millions)
	2007						2006
	Gross Book Value		Accumulated Amortization		Net Book Value		Gross Book Value		Accumulated Amortization		Net Book Value

Amortization expense was $124 million in 2007, $113 million in 2006 and $75 million in 2005.

The weighted average amortization period for all intangible assets is approximately 12 years.

Amortization expense for the subsequent five years is estimated to be as follows: 2008 – $122 million, 2009 – $99 million, 2010 – $87 million, 2011– $82 million and 2012 – $79 million.

11.    Long-term Debt and Debt Facility Agreements

Convertible Debentures

During 2003, Schlumberger Limited issued $975 million aggregate principal amount of 1.5% Series A Convertible Debentures due June 1, 2023 and $450 million aggregate principal amount of 2.125% Series B Convertible Debentures due June 1, 2023.

The Series A debentures and the Series B debentures are convertible, at the holders’ option, into shares of common stock of Schlumberger Limited. Holders of the Series A debentures may convert their debentures into common stock at a conversion rate of 27.651 shares for each $1,000 principal amount of Series A debentures (equivalent to an initial conversion price of $36.165 per share). Holders of the Series B debentures may convert their debentures into common stock at a conversion rate of 25.000 shares for each $1,000 principal amount of Series B debentures (equivalent to an initial conversion price of $40.00 per share). Each conversion rate may be adjusted for certain events, but it will not be adjusted for accrued interest.

On or after June 6, 2008 (in the case of the Series A debentures) or June 6, 2010 (in the case of the Series B debentures), Schlumberger may redeem for cash all or part of the applicable series of debentures, upon notice to the holders, at the redemption prices of 100% of the principal amount of the debentures, plus accrued and unpaid interest to the date of redemption. On June 1, 2008, June 1, 2013, and June 1, 2018, holders of Series A debentures may require Schlumberger to repurchase their Series A debentures. On June 1, 2010, June 1, 2013 and June 1, 2018, holders of Series B debentures may require Schlumberger to repurchase their Series B debentures. The repurchase price will be 100% of the principal amount of the debentures plus accrued and unpaid interest to the repurchase date. The repurchase price for repurchases on June 1, 2008 (in the case of the Series A debentures) and June 1, 2010 (in the case of the Series B debentures) will be paid in cash. On the other repurchase dates, Schlumberger may choose to pay the repurchase price in cash or common stock or any combination of cash and common stock. In addition, upon the occurrence of a Fundamental Change (defined as a change in control or a termination of trading of Schlumberger’s common stock), holders may require Schlumberger to repurchase all or a portion of their debentures for an amount equal to 100% of the principal amount of the debentures plus accrued and unpaid interest to the repurchase date. The repurchase price may be paid in cash, Schlumberger common stock (or if Schlumberger is not the surviving entity in a merger, the securities of the surviving entity) or a combination of cash and the applicable securities, at Schlumberger’s option. The applicable securities will be valued at 99% of their market price.

55

Part II, Item 8 

Schlumberger’s option to pay the repurchase price with securities is subject to certain conditions. The debentures will mature on June 1, 2023 unless earlier redeemed or repurchased.

During 2007, $622 million of the Series A debentures and $34 million of the Series B debentures were converted into 18 million shares of Schlumberger common stock.

At December 31, 2007, there were $353 million of the Series A debentures and $416 million of the Series B debentures outstanding. The fair value of the Series A and Series B debentures at December 31, 2007 was $956 million and $1.02 billion, respectively.

In September 2006, Schlumberger Finance B.V. issued €400 million Guaranteed Floating Rate Notes due 2009. Interest is payable quarterly at the rate of 10 basis points over 3-month Euribor. Schlumberger entered into an agreement to swap these Euro notes for US dollars on the date of issue until maturity, effectively making this US dollar denominated debt on which Schlumberger Finance B.V. will pay interest in US dollars at the rate of 3-month LIBOR plus 0.0875%. The carrying value of these Notes approximated their fair value at December 31, 2007.

The fair value of the $647 million of Schlumberger Technology Corporation 6.5% Notes due 2012 was $689 million at December 31, 2007.

The fair value of the $372 million of Schlumberger SA euro denominated 5.875% Guaranteed Bonds due 2011 was $386 million at December 31, 2007.

The fair value of the $255 million of Schlumberger Canada Limited 5.14% Guaranteed Notes due 2010, which are Canadian dollar denominated, approximated its carrying value as at December 31, 2007.

56

Part II, Item 8 

In connection with the Eastern Echo acquisition (see Note 4,Acquisitions), Schlumberger assumed 10.875% Senior Secured Bonds due May 2012 with par value of $160 million. The fair value of these both at the time of the acquisition was approximately $182 million and the carrying value approximated their fair value at December 31, 2007. These bonds can be redeemed at the following defined dates at the following multiples of par value:

May 2009 – May 2010	106	%
May 2010 – May 2011	104	%
May 2011 – Maturity	102	%

Commercial paper borrowings are classified as long-term debt to the extent of their backup by available and unused committed credit facilities maturing in more than one year and Schlumberger’s intent to maintain these obligations for longer than one year.

Commercial paper borrowings outstanding at December 31, 2007 and 2006 include certain notes issued in currencies other than the US dollar which were swapped for US dollars on the date of issue until maturity.

The weighted average interest rate on variable rate debt as of December 31, 2007 was 5.1%.

Other Long-term Debt as of December 31, 2007, which excludes the Convertible Debentures, is due as follows: $606 million in 2009, $520 million in 2010, $737 million in 2011 and $1.516 billion in 2012.

Debt Facility Agreements

On December 31, 2007, wholly-owned subsidiaries of Schlumberger had separate debt facility agreements aggregating $4.6 billion with commercial banks, of which $3.8 billion was committed and $2.3 billion was available and unused. This included $2.5 billion of committed facilities which support commercial paper programs in the United States and Europe, and mature in April 2012. Interest rates and other terms of borrowing under these lines of credit vary from country to country.

12.    Derivative Instruments and Hedging Activities

Schlumberger uses derivative instruments such as interest rate swaps, currency swaps, forward currency contracts and foreign currency options.

Schlumberger maintains a foreign-currency risk management strategy that uses derivative instruments to protect its interests from unanticipated fluctuations in earnings and cash flows caused by volatility in currency exchange rates. Forward currency contracts provide a hedge against currency fluctuations either on assets/liabilities denominated in other than a functional currency or on expenses. Schlumberger also maintains an interest rate risk management strategy that uses a mix of variable- and fixed-rate debt together with interest rate swaps, where appropriate, to fix or lower borrowing costs.

Schlumberger does not enter into foreign currency or interest rate derivatives for speculative purposes.

On December 31, 2007, interest rate swap arrangements outstanding were pay floating/receive fixed on US dollar debt of $40 million. These arrangements mature at various dates to December 2009. Interest rate swap arrangements decreased consolidated interest expense in 2007 by $0.4 million.

Currency exchange contracts are entered into as a hedge against the effect of future settlement of assets and liabilities denominated in other than the functional currency of the individual businesses. Gains or losses on the contracts are recognized when the currency exchange rates fluctuate, and the resulting charge or credit offsets the unrealized currency gains or losses on those assets and liabilities. On December 31, 2007, contracts were outstanding for the US dollar equivalent of $2.6 billion in various foreign currencies. These contracts mature on various dates in 2008.

At December 31, 2007, Schlumberger recognized a cumulative net $32 million gain in Stockholders’ Equity relating to derivative instruments and hedging activities. This gain was primarily due to the revaluation of foreign currency forward contracts at December 31, 2007.

Part II, Item 8 

13.    Capital Stock

Schlumberger is authorized to issue 3,000,000,000 shares of common stock, par value $0.01 per share, of which 1,195,616,324 and 1,177,893,459 shares were outstanding on December 31, 2007 and 2006, respectively. Schlumberger is also authorized to issue 200,000,000 shares of preferred stock, par value $0.01 per share, which may be issued in series with terms and conditions determined by the Board of Directors. No shares of preferred stock have been issued. Holders of common stock are entitled to one vote for each share of stock held.

14.    Stock Compensation Plans

Schlumberger has three types of stock-based compensation programs: stock options, a restricted stock and restricted stock unit program (collectively referred to as “restricted stock”) and a discounted stock purchase plan (“DSPP”).

Effective January 1, 2003, Schlumberger adopted the fair value recognition provisions of SFAS Nos. 123 (Accounting for Stock-Based Compensation) and 148 (Accounting for Stock-Based Compensation-Transition and Disclosure – an amendment of FASB Statement No. 123). Accordingly, Schlumberger began recording stock option and DSPP expense in theConsolidated Statement of Income on a prospective basis for grants after January 1, 2003.

In December 2004, the FASB issued SFAS 123R(Share-Based Payment).The standard amends SFAS 123 and concludes that services received from employees in exchange for stock-based compensation results in a cost to the employer that must be recognized in the financial statements. The cost of such awards should be measured at fair value at the date of grant.

Schlumberger adopted SFAS 123R effective January 1, 2006, and is applying the modified prospective method, whereby compensation cost will be recognized for the unvested portion of awards granted during the period from January 1, 1995 to December 31, 2002. Such costs are recognized in the financial statements of Schlumberger over the remaining vesting periods. Under this method, prior periods are not revised for comparative purposes.

Had compensation cost for stock-based awards granted prior to January 1, 2003 been determined based on the fair value at the grant dates, consistent with the fair value method of SFAS 123, Schlumberger’s net income and earnings per share in 2005 would have been the pro forma amounts indicated below:

Part II, Item 8 

Stock Options

Key employees are granted stock options under Schlumberger stock option plans. For all of the stock options granted, the exercise price of each option equals the average of the high and low sales prices of Schlumberger stock on the date of grant; an option’s maximum term is generally ten years, and options generally vest in increments over four or five years. The gain on the awards granted during the period from July 2003 to January 2006 is capped at 125% of the exercise price. Awards granted subsequent to January 2006 do not have a cap on any potential gain and generally vest in increments over five years.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions and resulting weighted-average fair value per share:

	2007			2006			2005
Dividend yield		1.1	%		0.8	%		1.3	%
Expected volatility		33	%		33	%		31	%
Risk free interest rates		4.7	%		4.3	%		3.8	%
Expected option life		6.9 years			6.1 years			4.5 years
Weighted-average fair value per share	$	25.94		$	20.03		$	7.12

The following table summarizes information concerning outstanding and exercisable options by five ranges of exercise prices as of December 31, 2007:

	OPTIONS OUTSTANDING				OPTIONS EXERCISABLE

The weighted average remaining contractual life of stock options exercisable as of December 31, 2007 was 4.46 years.

The following table summarizes stock option activity during the years ended December 31, 2007, 2006 and 2005:

The aggregate intrinsic value of stock options outstanding as of December 31, 2007 was approximately $2.1 billion. The aggregate intrinsic value of stock options exercisable as of December 31, 2007 was approximately $1.3 billion.

The total intrinsic value of options exercised during the years ended December 31, 2007, 2006 and 2005, was approximately $607 million, $366 million and $193 million, respectively.

Part II, Item 8 

Restricted Stock

On April 12, 2006, the stockholders of Schlumberger approved amendments to Schlumberger’s 2005 Stock Option Plan. These amendments included providing for the grant of restricted stock with respect to up to 3,000,000 shares of common stock, and providing that restricted stock may not be granted to executive officers of Schlumberger unless the grants are subject to performance-based vesting.

Restricted stock awards generally vest at the end of three years, with the exception of certain grants which vest over a two-year period with a two-year holding period. There have not been any grants to date that are subject to performance-based vesting.

The following table summarizes information about restricted stock transactions:

	2007				2006

Unvested at end of year	884,600		$	65.14	636,800		$	65.21

Discounted Stock Purchase Plan

Under the terms of the DSPP, employees can choose to have up to 10% of their annual earnings withheld to purchase Schlumberger common stock. The purchase price of the stock is 92.5% of the lower of the stock price at the beginning or end of the plan period at six-month intervals.

The fair value of the employees’ purchase rights under the DSPP was estimated using the Black-Scholes model with the following assumptions and resulting weighted average fair value per share:

	2007			2006			2005
Dividend yield		0.9	%		1.1	%		1.4	%

15.    Income Tax Expense

Schlumberger and its subsidiaries operate in more than 100 taxing jurisdictions where statutory tax rates generally vary from 0% to 50%.

As more fully described in Note 3Charges and Credits, Schlumberger recorded a pretax credit outside the United States in 2007 of $25 million, pretax charges in 2006 of $46 million ($19 million in the United States; $27 million outside the United States) and net pretax credits in 2005 of $172 million ($19 million of net credits in the United States; $153 million of credits outside the United States).

Pretax book income subject to United States and non-United States income taxes for each of the three years ended December 31, was as follows:

(Stated in millions)
	2007		2006		2005
United States	$	1,754	$	1,582	$	892
Outside United States		4,870		3,366		2,080
Pretax income	$	6,624	$	4,948	$	2,972

The components of net deferred tax assets were as follows:

Postretirement and other long-term benefits	$	244	$	394
Current employee benefits		29		31
Fixed assets, inventory and other		124		151
	$	397	$	576

The above deferred tax assets at December 31, 2007 and 2006 are net of valuation allowances relating to net operating losses in certain countries of $214 million and $218 million, respectively. The deferred tax assets are also net of valuation allowances relating to a capital loss carryforward of $144 million at December 31, 2007 ($151 million at December 31, 2006) which expires in 2009 and 2010, and a foreign tax credit carryforward of $55 million at December 31, 2007 ($55 million at December 31, 2006) which expires in 2009 through 2012.

The components of consolidated income tax expense were as follows:

Schlumberger adopted the provisions of FASB Interpretation No. 48,Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109 (“FIN 48”) on January 1, 2007. This interpretation clarifies the accounting for uncertain tax positions and requires companies to recognize the impact of a tax position in their financial statements, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The adoption of FIN 48 did not have any impact on the total liabilities or stockholders’ equity of Schlumberger.

A reconciliation of the beginning and ending amount of liabilities associated with uncertain tax positions is as follows:

(Stated in millions)
Balance at January 1, 2007	$	730
Additions based on tax positions related to the current year		187
Additions for tax positions of prior years		16
Impact of changes in exchange rates		21
Settlements with tax authorities		(8	)
Reductions for tax positions of prior years		(55	)
Reductions due to the lapse of the applicable statute of limitations		(33	)
Balance at December 31, 2007	$	858

Included in the SchlumbergerConsolidated Balance Sheet at December 31, 2007 is approximately $858 million of liabilities associated with uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business, a number of which have tax laws that are not fully defined and are evolving. This amount excludes $130 million of accrued interest and penalties. All but $25 million of the unrecognized tax benefits, if recognized, would impact the Schlumberger effective tax rate.

Schlumberger classifies interest and penalties relating to uncertain tax positions withinTaxes on income in theConsolidated Statement of Income. During 2007, Schlumberger recognized approximately $36 million in interest and penalties.

The following table summarizes the tax years that are either currently under audit or remain open and subject to examination by the tax authorities in the most significant jurisdictions in which Schlumberger operates:

Canada	2002 – 2007
Mexico	2002 – 2007
Russia	2004 – 2007
Saudi Arabia	2001 – 2007
United Kingdom	2004 – 2007
United States	2003 – 2007

62

Part II, Item 8 

In certain of the jurisdictions noted above, Schlumberger operates through more than one legal entity, each of which has different open years subject to examination. The table above presents the open years subject to examination for the most material of the legal entities in each jurisdiction. Additionally, it is important to note that tax years are technically not closed until the statute of limitations in each jurisdiction expires. In the jurisdictions noted above, the statute of limitations can extend beyond the open years subject to examination.

Due to the geographic breadth of the Schlumberger operations, numerous tax audits may be ongoing throughout the world at any point in time. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. In such an event, Schlumberger will record additional tax expense or tax benefit in the period in which such resolution occurs.

16.    Leases and Lease Commitments

Total rental expense was $913 million in 2007, $686 million in 2006, and $532 million in 2005. Future minimum rental commitments under noncancelable operating leases for each of the next five years are as follows:

(Stated in millions)
2008	$	213
2009		165
2010		110
2011		77
2012		58
Thereafter		279
	$	902

17.    Contingencies

TheConsolidated Balance Sheet includes accruals for estimated future expenditures, relating to contractual obligations associated with business divestitures that have been completed. It is possible that the ultimate expenditures may differ from the amounts recorded. In the opinion of management, such differences are not expected to be material relative to Schlumberger’s consolidated liquidity, financial position or future results of operations.

In July 2007, Schlumberger received an inquiry from the United States Department of Justice (“DOJ”) related to the DOJ’s investigation of whether certain freight forwarding and customs clearance services of Panalpina, Inc., and other companies provided to oil and oilfield service companies, including Schlumberger, violated the Foreign Corrupt Practices Act. Schlumberger is cooperating with the DOJ and is conducting its own investigation with respect to these services.

In December 2004, WesternGeco L.L.C. and Schlumberger Technology Corporation received federal grand jury subpoenas issued by the United States District Court for the Southern District of Texas. The subpoenas sought documents relating to possible fraud in obtaining visas for foreign crewmembers working on vessels operating on the Outer Continental Shelf of the Gulf of Mexico. On June 16, 2006, WesternGeco L.L.C. entered into an agreement with the United States Attorney’s Office for the Southern District of Texas resolving the issues raised in the federal investigation. Under the terms of the agreement, WesternGeco L.L.C. accepted responsibility for U.S. visa violations and agreed to pay a monetary penalty of $18 million and reimburse the United States Government for $1.6 million in investigation expenses. Additionally, WesternGeco L.L.C. entered into a twelve-month Deferred Prosecution Agreement (“DPA”), during which time its Gulf of Mexico activities were subject to monitoring by the United States Government. At the conclusion of this twelve-month period on

63

Part II, Item 8 

June 16, 2007, WesternGeco L.L.C. was determined to have complied with the terms of the DPA. As a result, the DPA expired and no prosecution arising from the investigation will be brought. Moreover, WesternGeco has developed and implemented a comprehensive visa and immigration compliance program designed to prevent a recurrence of improper visa practices.

Schlumberger and its subsidiaries are party to various legal proceedings. A liability is accrued when a loss is both probable and can be reasonably estimated. At this time the ultimate disposition of these proceedings is not presently determinable and therefore, it is not possible to estimate the amount of loss or range of possible losses that might result from an adverse judgment or settlement in any of these matters. However, in the opinion of management, any liability that might ensue would not be material in relation to Schlumberger’s consolidated liquidity, financial position or future results of operations.

18.    Segment Information

Schlumberger operates two business segments: Oilfield Services and WesternGeco.

The Oilfield Services segment falls into four clearly defined economic and geographical areas and is evaluated on the following basis: North America is a major self-contained market; Latin America comprises regional markets that share a common dependence on the oil and gas industry; Europe is a major self-contained market that includes the CIS and Africa, whose economy is increasingly linked to that of Europe; Middle East & Asia includes the remainder of the Eastern Hemisphere, which consists of many countries at different stages of economic development that share a common dependence on the oil and gas industry. The OFS segment provides virtually all exploration and production services required during the life of an oil and gas reservoir.

The WesternGeco segment provides comprehensive worldwide reservoir imaging, monitoring, and development services, with extensive seismic crews and data processing centers, as well as a large multiclient seismic library. Services range from 3D and time-lapse (4D) seismic surveys to multi-component surveys for delineating prospects and reservoir management.

Effective January 1, 2007, a component of the Middle East & Asia Area has been reallocated to the Europe/CIS/Africa Area and certain activities have been reallocated between OFS and WesternGeco. Historical segment information has been reclassified to conform to the new presentation.

Effective January 1, 2008, a component of the Middle East & Asia Area has been reallocated to the Europe/CIS/Africa Area. Commencing with Schlumberger’s Form 10-Q and earnings press release for the quarter ending March 31, 2008, historical segment information will be reclassified to conform to the new presentation.

Oilfield Services Elims/Other include certain headquarters administrative costs which are not allocated geographically, manufacturing and certain other operations, and costs maintained at the Oilfield Services level.

Corporate items principally comprise nonoperating expenses, such interest on postretirement benefits, stock-based compensation costs, corporate expenses and interest expense (except as shown above), which are not included in the segments’ income. Corporate assets largely comprise short-term investments and fixed income investments, held to maturity.

During the three years ended December 31, 2007, no single customer exceeded 10% of consolidated revenue.

Schlumberger did not have revenue from third-party customers in its country of domicile during the last three years. Revenue in the United States in 2007, 2006 and 2005 was $5.6 billion, $5.2 billion and $3.5 billion, respectively.

Interest expense excludes amounts which are included in the segments’ income (2007 – $7 million: 2006 –$6 million: 2005 – $10 million).

Depreciation & Amortization and Capital Expenditure include Multiclient seismic data costs.

Part II, Item 8 

19.    Pension and Other Benefit Plans

Adoption of SFAS 158

Effective December 31, 2006, Schlumberger adopted the provisions of SFAS 158 (Employer’s Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R)). SFAS 158 requires Schlumberger to recognize the funded status (i.e., the difference between the fair value of plan assets and the benefit obligation) of its defined benefit pension and other postretirement plans (collectively “postretirement benefit plans”) in itsConsolidated Balance Sheet, with a corresponding adjustment toAccumulated Other Comprehensive Income, net of tax.

The adjustment toAccumulated Other Comprehensive Income at adoption represents the net unrecognized actuarial losses and unrecognized prior service costs which were previously netted against Schlumberger’s postretirement benefit plans’ funded status in theConsolidated Balance Sheet pursuant to the provisions of SFAS 87 (Employers’ Accounting for Pensions)and SFAS 106 (Employer’s Accounting for Postretirement Benefits Other Than Pensions). These amounts are subsequently recognized as net periodic postretirement cost consistent with Schlumberger’s historical accounting policy for amortizing such amounts. The adoption of SFAS 158 had no effect on Schlumberger’sConsolidated Statement of Income for any prior periods, and it will not affect Schlumberger’s operating results in future periods.

Upon the adoption of SFAS 158 on December 31, 2006, Schlumberger’s total liabilities increased by approximately 2% and stockholders’ equity decreased by approximately 3%. The impact on Schlumberger’s total assets was insignificant.

United States Defined Benefit Pension Plans

Schlumberger and its United States subsidiary sponsor several defined benefit pension plans that cover substantially all employees hired prior to October 1, 2004. The benefits are based on years of service and compensation on a career-average pay basis. The funding policy with respect to qualified pension plans is to annually contribute amounts that are based upon a number of factors including the actuarial accrued liability, amounts that are deductible for income tax purposes, legal funding requirements and available cash flow.

The assumed discount rate, compensation increases and return on plan assets used to determine pension expense were as follows:

	2007		2006		2005
Assumed discount rate	6.00	%	5.75	%	6.00	%
Compensation increases	4.00	%	3.00	%	3.00	%
Return on plan assets	8.50	%	8.50	%	8.50	%

Net pension cost in the United States for 2007, 2006 and 2005, included the following components:

(Stated in millions)
	2007			2006			2005
Service cost – benefits earned during the period	$	58		$	59		$	53
Interest cost on projected benefit obligation		120			112			108
Expected return on plan assets [actual return: 2007 – $212; 2006 – $224; 2005 – $132]		(147	)		(134	)		(109	)
Amortization of prior service cost		7			8			8
Amortization of net loss		26			27			25
Net pension cost	$	64		$	72		$	85

Part II, Item 8 

Included inAccumulated Other Comprehensive Income at December 31, 2007 are the following non-cash pretax charges which have not yet been recognized in net periodic pension cost. Also presented is the estimated portion of each component ofAccumulated Other Comprehensive Income which is expected to be recognized as a component of net periodic benefit cost during the year ending December 31, 2008.

The changes in the projected benefit obligation, plan assets and funded status of the plans on December 31, 2007 and 2006, were as follows:

(Stated in millions)
	2007			2006
Projected benefit obligation at beginning of the year	$	2,006		$	1,984
Service cost		58			59
Interest cost		120			112
Actuarial (gain)/losses		(57	)		(89	)
Benefits paid		(97	)		(95	)
Amendments		–			2
Other		–			33
Projected benefit obligation at end of the year	$	2,030		$	2,006
Plan assets at market value at beginning of the year	$	1,913		$	1,588
Actual return on plan assets		212			224
Contributions		152			204
Benefits paid		(97	)		(95	)
Administrative expense		(10	)		(8	)
Plan assets at market value at end of the year	$	2,170		$	1,913
Overfunded/(underfunded) position at end of year	$	140		$	(93	)

The overfunded/(underfunded) position represents the difference between the plan assets and the projected benefit obligation (“PBO”). The PBO represents the actuarial present value of benefits based on employee service and compensation and includes an assumption about future compensation levels.

The $140 million overfunded position of the United States defined benefit pension plan at December 31, 2007 is included inOther Assets in the accompanyingConsolidated Balance Sheet.

The $93 million underfunded position at December 31, 2006 is included inPostretirement Benefits in the accompanyingConsolidated Balance Sheet.

The assumed discount rate, the rate of compensation increases and the expected long-term rate of return on plan assets used to determine the projected benefit obligations were as follows:

	2007		2006
Assumed discount rate	6.50	%	6.00	%
Compensation increases	4.00	%	3.00	%
Return on plan assets	8.50	%	8.50	%

Part II, Item 8 

The following is a breakdown of the plan assets:

(Stated in millions)
	2007		2006
US equity securities	$	990	$	905
Non-US equity securities		433		449
Fixed income securities		563		374
Cash and cash equivalents		38		85
Other investments		146		100
	$	2,170	$	1,913

The asset allocation objectives are to diversify the portfolio among several asset classes to reduce volatility while maintaining an asset mix that provides the highest expected rate of return consistent with an acceptable level of risk. The investment strategies include a rebalancing of the asset mix as necessary to the previously defined levels and reassessing funding levels and asset allocation strategy at least annually.

As at December 31, 2007, there was no investment of plan assets in Schlumberger common stock.

The expected long-term rate of return on assets is 8.5%. This assumption represents the rate of return on plan assets reflecting the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation. The assumption has been determined by reflecting expectations regarding future rates of return for the portfolio considering the asset distribution and related historical rates of return. The appropriateness of the assumption is reviewed annually.

The expected benefits to be paid under the plan are as follows:

(Stated in millions)
2008	$	99
2009	$	100
2010	$	102
2011	$	105
2012	$	109
2013 – 2017	$	616

No plan assets are expected to be returned to Schlumberger during the year ending December 31, 2008.

Although not required to make any contributions to its US qualified pension plans in 2008, Schlumberger currently expects to make contributions in 2008 of between $50 million and $100 million.

Other Defined Benefit Pension Plans

In addition to the previously disclosed United States defined benefit pension plans, Schlumberger sponsors several other defined benefit pension plans. Charges to expense for these plans were $58 million, $49 million and $50 million in 2007, 2006 and 2005, respectively, and are based upon costs computed by actuaries.

The most significant of these other defined benefit pension plans is in the UK, which covers employees hired prior to April 1, 1999.

The assumed discount rate, compensation increases and return on plan assets used to determine pension expense were as follows:

	2007		2006		2005
Assumed discount rate	5.20	%	4.90	%	5.40	%
Compensation increases	4.50	%	4.20	%	4.10	%
Return plan assets	8.00	%	8.00	%	8.00	%

Net pension cost in the UK plan for 2007, 2006 and 2005 (translated into US dollars at the average exchange rate for the periods), included the following components:

Other Deferred Benefits

In addition to providing defined pension benefits, Schlumberger and its subsidiaries have other deferred benefit programs, primarily profit sharing and defined contribution pension plans. Expenses for these programs were $408 million, $351 million and $280 million in 2007, 2006 and 2005, respectively.

The costs of providing these benefits are expensed when incurred, and aggregated $80 million, $72 million and $65 million in 2007, 2006 and 2005, respectively. Outside the United States, such benefits are mostly provided through government-sponsored programs.

Postretirement Benefits Other than Pensions

Schlumberger and its United States subsidiary provide certain health care benefits to former employees who have retired.

The principal actuarial assumptions used to measure costs were a discount rate of 6.00% in 2007, 5.75% in 2006 and 6.00% in 2005. The overall medical cost trend rate assumption is 9% graded to 6% over the next four years and 5% thereafter.

Retirees	$	403	$	418
Fully eligible		255		217
Actives		134		150
	$	792	$	785

The assumed discount rate used to determine the accumulated postretirement benefit obligation was 6.50% for 2007 and 6.00% for 2006.

The overall medical cost trend rate assumption used to determine the accumulated postretirement benefit obligation for both 2007 and 2006 was 9% graded to 6% over the next four years and 5% thereafter.

If the assumed medical cost trend rate was increased by one percentage point per annum, health care cost in 2007 would have been $68 million, and the accumulated postretirement benefit obligation would have been $929 million on December 31, 2007.

If the assumed medical cost trend rate was decreased by one percentage point per annum, health care cost in 2007 would have been $45 million, and the accumulated postretirement benefit obligation would have been $712 million on December 31, 2007.

Part II, Item 8

Management’s Report on Internal Control Over Financial Reporting

The management of Schlumberger Limited is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a – 15(f) of the Securities Exchange Act of 1934, as amended. Schlumberger Limited’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Schlumberger Limited management assessed the effectiveness of our internal control over financial reporting as of December 31, 2007. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) inInternal Control – Integrated Framework. Based on our assessment we have concluded that, as of December 31, 2007, our internal control over financial reporting is effective based on those criteria.

The effectiveness of Schlumberger Limited’s internal control over financial reporting as of December 31, 2007, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Part II, Item 8

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

of Schlumberger Limited

In our opinion, the accompanying consolidated balance sheet and the related consolidated statements of income, of stockholders’ equity and of cash flows present fairly, in all material respects, the financial position of Schlumberger Limited and its subsidiaries at December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2007 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing on page 74 of this Annual Report on Form 10-K. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 14 to the consolidated financial statements, the Company changed its method of accounting for stock-based compensation on January 1, 2006. Additionally, as discussed in Note 19 to the consolidated financial statements, the Company changed its method of accounting for defined benefit pension and other postretirement plans on December 31, 2006. Furthermore, as discussed in Note 15 to the consolidated financial statements, the Company changed its method of accounting for uncertainty in income taxes on January 1, 2007.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

75

Part II, Item 8

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
