                       REPORT OF INDEPENDENT AUDITORS



To the Shareholders Representatives Committee and Owners of
WesternGeco



In our opinion, the accompanying combined balance sheets and the related
combined statements of operations and comprehensive income, of owners' net
investment and of cash flows present fairly, in all material respects, the
financial position of WesternGeco (the "Venture") at December 31, 2003 and 2002,
and the results of its operations and its cash flows for each of the three years
in the period ended December 31, 2003, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Venture's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes 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.
We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 2 to the combined financial statements, effective January
1, 2002, the Company changed its method of accounting for goodwill in accordance
with Statement of Financial Accounting Standards No. 142, Goodwill and Other
Intangible Assets.

As discussed in Note 10 and Note 12 to the combined financial statements, the
Venture has significant transactions with related parties.

1.    BUSINESS AND ORGANIZATION

      WesternGeco is comprised of WesternGeco LLC, a Delaware limited liability
      company, WesternGeco Ltd., a United Kingdom limited liability company,
      WesternGeco Seismic Holdings ("B.V.I.") Ltd., a British Virgin Islands
      company, WesternGeco B.V., a Netherlands company, and WesternGeco Canada,
      a Canadian partnership, together with their respective subsidiaries
      (collectively, "WesternGeco" or the "Venture").

      WesternGeco was formed on December 1, 2000, with the contribution by
      Schlumberger Limited ("Schlumberger") and Baker Hughes Incorporated
      ("BHI") of their seismic operations. Concurrently, Schlumberger paid
      $500,000 to BHI in exchange for a 70 percent interest in the Venture.
      WesternGeco Canada was formed on November 1, 2003, with a $75 cash
      contribution by Schlumberger and BHI. The five entities that comprise
      WesternGeco are each 70 percent owned by Schlumberger and affiliated
      companies and 30 percent owned by BHI and affiliated companies
      (collectively, the "Owners"). Specific terms and conditions of the venture
      are included, or referred to, in a Master Formation Agreement dated
      September 6, 2000.

      WesternGeco provides comprehensive worldwide reservoir imaging,
      monitoring, and development services, with extensive seismic crews and
      data processing centers, as well as having a multiclient seismic library
      available for licensing. Services range from 2D, 3D and time-lapse (4D)
      seismic surveys to multicomponent surveys for delineating prospects and
      reservoir management.


2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

      The combined financial statements include accounts of the Venture and all
      majority-owned subsidiaries. All significant intercompany accounts and
      transactions have been eliminated.

      Individual assets and liabilities initially contributed to the Venture by
      Schlumberger, including goodwill contributed to the Venture from previous
      transactions, were recorded using their respective historical carrying
      values at the date of contribution. Individual assets and liabilities
      contributed to the Venture by BHI were recorded using their respective
      fair values at the date of contribution. The excess of purchase price over
      the estimated fair value of the net assets at contribution was $126,000,
      which has been recorded as goodwill and was being amortized over 15 years
      prior to the adoption of Statement of Financial Accounting Standards No.
      142, Goodwill and Other Intangible Assets ("SFAS No. 142") in 2002.

      USE OF ESTIMATES

      The preparation of financial statements in conformity with accounting
      principles generally accepted in the United States of America 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. Actual
      results could differ from those estimates.

      TRANSLATION OF FOREIGN CURRENCIES

      The Venture's foreign subsidiaries predominately have the U.S. dollar
      designated as their functional currency. Financial statements of these
      foreign subsidiaries are remeasured to U.S. dollars for consolidation
      purposes using current rates of exchange for monetary assets and
      liabilities and historical rates of exchange for nonmonetary assets and
      related elements of expense. Revenue and other expense elements are
      remeasured at rates that approximate the rates in effect on the
      transaction dates. Remeasurement gains and losses are included in the
      Venture's combined statement of operations. Certain foreign subsidiaries
      designate the local currency as their functional currency and the related
      cumulative translation adjustments are included as a component of
      accumulated other comprehensive income.

      DERIVATIVE FINANCIAL INSTRUMENTS

      Derivative financial instruments are recognized at fair value. The Venture
      uses derivative financial instruments, such as foreign currency forward
      contracts, to mitigate the impact of changes in foreign currency exchange
      rates. The accounting for realized and unrealized gains and losses from
      derivative financial instruments depends upon the intended use of the
      derivative and the resulting designation. For derivative financial
      instruments designated as cash flow hedges, gains and losses, to the
      extent the hedge is effective, are recognized in other comprehensive
      income until the hedged item is recognized in earnings in other income and
      expense, net. Any change in fair value resulting from ineffectiveness is
      recognized immediately in earnings in other expense and income, net. At
      December 31, 2003, no contracts designated as cash flow hedges were
      outstanding. At December 31, 2002, contracts with a notional value of
      $22,572 were outstanding for the Norwegian kroner and U.K. pound. At
      December 31, 2003 and 2002, $0 and $2,417 were deferred in accumulated
      other comprehensive income, respectively. For derivative financial
      instruments entered to offset the change in foreign currency exchange
      rates related to the future settlement of assets and liabilities
      denominated in other than the functional currency, gains and losses are
      recognized when the currency exchange rates fluctuate, resulting in an

      At December 31, 2003 and 2002, $3,991 and $5,829, respectively, was
      included in other assets relating to derivate financial instruments.

      FAIR VALUE OF FINANCIAL INSTRUMENTS

      The reported amounts of financial instruments such as cash, short-term
      investments, receivables and accounts payable approximate fair value
      because of their short maturities. The reported amounts of debt
      approximate fair values because of their variable interest rates.

      RISKS AND UNCERTAINTIES

      Since the Venture operates in many countries, the business is subject to
      varying degrees of risk and uncertainty. The Venture insures its business
      and assets against insurable risks in a manner that it deems appropriate.
      Because of its diversity, the Venture believes that the risk of loss from
      uninsured events in any one country would not have a material, adverse
      effect on its operations as a whole. Additionally, management believes
      there is no material concentration of risk within any single customer or
      supplier, or small group of customers or suppliers, whose failure or
      nonperformance would materially affect the Venture's financial position.
      For the year ended December 31, 2003, revenue from one customer accounted
      for 12 percent of total revenue. For the years ended December 31, 2002 and
      2001, no customer accounted for more than 10 percent of total revenue. At
      December 31, 2003, the Company had receivables outstanding from two
      customers that comprised 13 percent and 10 percent of total trade
      receivables, respectively. At December 31, 2002, no customer had an
      outstanding balance greater than 10 percent of total trade receivables.

      REVENUE RECOGNITION

      Revenues from contract services performed on a dayrate basis are
      recognized as the service is performed. Revenues from other contract
      services are recognized as the seismic data is acquired or processed.
      Multiclient data surveys are licensed to customers on a nontransferable
      basis. Revenues on completed multiclient data surveys are recognized upon
      obtaining a signed license agreement and providing customers access to
      such data. Revenues on in-process multiclient data surveys are recognized
      after obtaining a signed licensing agreement as the seismic data is
      acquired and processed, similar to other contract services.

      RESEARCH AND ENGINEERING COSTS

      Research and engineering costs are expensed as incurred.

      CASH

      Cash includes cash on hand and demand deposits with banks.

      SHORT-TERM INVESTMENTS

      Short-term investments are held to maturity and stated at cost plus
      accrued interest, which approximates market value, and comprise primarily
      certificates of deposit and time deposits. Short-term investments include
      certain time deposits that are held through an affiliate in the amounts of
      $119,544 and $174,984 at December 31, 2003 and 2002, respectively.

      INVENTORIES

      Inventories consist of parts and raw materials and are stated at the lower
      of cost or market, cost being determined on the average cost basis.

      MULTICLIENT LIBRARY

      The multiclient library consists of completed and in-process seismic
      surveys that are licensed on a nonexclusive basis. All capitalizable costs
      associated with acquiring and processing the data are capitalized into the
      multiclient library. Costs capitalized during the years ended December 31,
      2003, 2002 and 2001, were $149,767, $344,705 and $458,188, respectively.
      Such costs are charged to multiclient amortization based on the percentage
      of the total costs to estimated total revenue that the Venture expects to
      receive from multiclient surveys. Additionally, each survey is amortized
      over a maximum of 4 years. No individual survey carries a net book value
      above the straight-line amortized value.

(in thousands of dollars)

      The carrying value of the multiclient library is periodically reviewed to
      determine whether there has been a permanent impairment of value.
      Adjustments to the value are recorded when it is determined that estimated
      sales would not be sufficient to recover the carrying value of the asset
      (Note 3).

      PROPERTY, PLANT AND EQUIPMENT

      Property, plant and equipment are stated at cost, less accumulated
      depreciation. Depreciation is computed using the straight-line method over
      the estimated useful lives of the assets which are as follows:

      
      
                                                                                  YEARS

      Other equipment                                                             2 - 15
      Furniture, fixtures and office equipment                                    5 - 12
      

      Maintenance and repairs are charged to operating expenses as incurred.

      TAXES ON INCOME

      The Venture accounts for income taxes using the asset and liability
      approach. The asset and liability approach requires the recognition of
      deferred tax assets and liabilities for the expected future tax
      consequences of temporary differences between the carrying amounts and the
      tax basis of certain assets and liabilities. The income tax provision and
      related accounts in the accompanying combined financial statements are
      primarily related to operations outside the United States ("U.S."). The
      Owners or their affiliates are directly responsible for U.S. income taxes
      on WesternGeco LLC earnings and Canadian income taxes on WesternGeco
      Canada earnings. Therefore, no such taxes are provided on the U.S.
      earnings of WesternGeco LLC and the Canadian earnings of WesternGeco
      Canada in the combined financial statements. Valuation allowances are
      recorded to reduce deferred tax assets when it is more likely than not
      that a deferred tax asset will not be realized by the Venture.

      GOODWILL

      The excess purchase price over the fair value of assets acquired is
      recorded as goodwill. Beginning in 2002 with the adoption of SFAS No. 142,
      goodwill is no longer amortized, but is tested for impairment annually and
      when an event occurs or circumstances change that would cause the fair
      value of a reporting unit to be below its carrying amount. Prior to 2002,
      goodwill was amortized using the straight-line method over its estimated
      period of benefit of 15-25 years. Accumulated amortization was $9,896 at
      December 31, 2003 and 2002.

      OTHER INTANGIBLE ASSETS

      Other intangible assets, which are stated at cost less accumulated
      amortization, consist primarily of purchased software. The purchased
      software is amortized over 15 years, which is the expected useful life.
      Other intangible assets are amortized over 5 to 20 years. Accumulated
      amortization was $16,010, $9,806 and $3,946 at December 31, 2003, 2002 and
      2001, respectively. Amortization expense for the years ended December 31,
      2003, 2002 and 2001 was $6,204, $5,860 and $6,085, respectively.
      Amortization expense for the next five years is estimated to be:

      IMPAIRMENT OF LONG LIVED ASSETS

      In accordance with Statement of Financial Accounting Standards No. 144,
      Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS No.
      144"), the Venture assesses potential impairments of long-lived assets and
      identifiable intangible assets when there is evidence that events or
      changes in circumstances may have made recovery of an asset's carrying
      value uncertain. For assets held and used, an impairment loss is
      recognized when the sum of the expected, future undiscounted net cash flow
      is less than the carrying amount of the asset.

      MOBILIZATION COSTS

      Transportation and other expenses incurred prior to commencement of
      seismic operations where a customer contract already exists are deferred
      and amortized over the term of the related contract. Transportation or
      other expenses incurred prior to commencement of seismic operations for a
      multiclient project are capitalized as a part of the multiclient library.
      Expenses incurred to relocate seismic units not under contract are
      expensed as incurred.

      RECENT ACCOUNTING PRONOUNCEMENTS

      In July 2002, the Financial Accounting Standards Board ("FASB") issued
      Statement of Financial Accounting Standards No. 146, Accounting for Exit
      or Disposal Activities ("Statement No. 146"). Statement No. 146 addresses
      issues regarding the recognition, measurement and reporting of costs that
      are associated with exit and disposal activities, including restructuring
      activities. The scope of Statement No. 146 also includes (1) costs related
      to terminating a contract that is not a capital lease and (2) termination
      benefits that employees who are involuntarily terminated receive under the
      terms of a one-time benefit arrangement that is not an ongoing benefit
      arrangement or an individual deferred compensation contract. Statement No.
      146 was effective for exit or disposal activities that were initiated
      after December 31, 2002. The Company adopted Statement No. 146 effective
      January 1, 2003, with no impact upon its financial position or results of
      operations.

      In December 2003, the FASB issued Statement of Financial Accounting
      Standards No. 132 (revised 2003) Employers' Disclosures About Pensions and
      Other Postretirement Benefits ("Statement No. 132R"). Statement No. 132R
      requires additional disclosures to those in the original Statement 132
      about the assets, obligations, cash flows, and net periodic benefit cost
      of defined benefit pension plans and other defined benefit postretirement
      plans. The Venture adopted Statement No. 132R for the year ended December
      31, 2003.

      In January 2004, the FASB issued FSP No. FAS 106-1 (Accounting and
      Disclosure Requirements Related to the Medicare Prescription Drug
      Improvement and Modernization Act of 2003). The statement permits the
      deferral of accounting related to the effects of the legislation until the
      earlier of issuance of final accounting guidance by the FASB or a
      significant plan amendment/curtailment event requiring remeasurement,
      occurring after January 31, 2004. The Venture is assessing the impact of
      the new legislation upon future postretirement medical costs.

      RECLASSIFICATIONS

      Certain prior year amounts have been reclassified to conform to current
      year presentation.

      During the year ended December 31, 2002, the Venture's management approved
      a restructuring plan to reduce infrastructure and overhead, remove several
      marine vessels from service, cease all U.S. land acquisition activity and
      writedown certain assets. Employee separation costs were for approximately
      1,700 employees, impacting the majority of business functions, job classes
      and geographic regions. Employee separation benefits included severance,
      medical and other benefits. Other exit costs consisted of vessel stacking,
      de-rigging costs, lease cancellation and other costs primarily related to
      the removal from service of nine vessels and all U.S. land crews. The
      activity related to the restructure action is as follows:

      the U.S. statutory income tax rate and unbenefitted foreign losses of the
      Venture.

      In the course of its business affairs and operations, the Venture is
      subject to possible loss contingencies arising from local laws and
      regulations. Additionally, the Venture is subject to certain litigation
      matters arising from the normal course of business. Management has
      recorded a reserve for these matters to the extent management has
      concluded these matters are probable and can be reasonably estimated. In
      the opinion of management, there are no other matters which could have a
      material adverse effect on the financial position, results of operations
      or cash flows of the Venture.

      The Department of Commerce, Department of the Navy and Department of

      Venture in December 2000. Under the master formation agreement, BHI
      indemnifies the Venture for this matter. The Venture is cooperating fully
      with the U.S. Agencies and with BHI.

10.   RELATED PARTY TRANSACTIONS

      The combined financial statements include costs for certain functions and
      services such as treasury services, information technology services, rent
      and other corporate and infrastructure costs performed or incurred by
      Schlumberger's centralized organizations and directly charged to the
      Venture based on usage. These allocations, which are based on the
      assumptions that Schlumberger's and the Venture's management believes are
      reasonable under the circumstances, resulted in charges of $28,354,
      $26,279 and $21,375 for 2003, 2002 and 2001, respectively.

      The Venture leases certain properties from BHI. Payments made under the
      lease during the years ended December 31, 2003, 2002 and 2001, were
      $4,992, $5,503 and $4,592, respectively. Additionally, certain of the
      Venture's leases are guaranteed by Schlumberger.

      The payables to affiliates balance includes amounts due to Schlumberger
      affiliates relating to asset purchases and direct operating costs.

      During the years ended December 31, 2003, 2002 and 2001, Schlumberger
      granted options to purchase common stock to Venture employees and issued
      common shares to Venture employees under a direct stock purchase program
      (Note 12).

      Certain of the Venture's excess cash funds are held by an affiliated
      entity and are included in the combined balance sheet as short-term
      investments. The balances held by the affiliate on behalf of the Venture
      at December 31, 2003 and 2002, were $119,544 and $174,984, respectively.

      The combined financial statements also include interest expense of $235,
      $1,202 and $1,010 associated with debt payable to associated companies and
      interest income of $1,352, $1,642 and $2,950 associated with receivables
      from associated companies for the years ended December 31, 2003, 2002 and
      2001, respectively.

11.   PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

      The Venture sponsors a defined benefit pension plan and a postretirement
      plan in the United States while Schlumberger sponsors a defined benefit
      pension plan in the United Kingdom (U.K.) that covers Venture employees.
      The benefits associated with these benefit plans are based on years of
      service with the Venture combined with years of service with either
      Schlumberger or BHI affiliates and compensation on a career-average pay
      basis. Charges to expense are based upon costs of the plans, as computed
      by independent actuaries. In addition, the Venture has statutory pension
      plans in various other foreign countries. The Venture's total pension
      expense was $16,206, $14,844 and $7,186 for 2003, 2002 and 2001,
      respectively.

      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 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.

      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 at least annually.

      If the assumed medical cost trend rate was increased by one percentage
      point, health care cost in 2003 would have been $10,085, and the
      accumulated postretirement benefit obligation would have been $94,445 on
      December 31, 2003.

      If the assumed medical cost trend rate was decreased by one percentage
      point, health care cost in 2003 would have been $6,371, and the
      accumulated postretirement benefit obligation would have been $59,170 on
      December 31, 2003.

12.   STOCK-BASED COMPENSATION AND OTHER EMPLOYEE BENEFITS

      In addition to the pension and other postretirement benefit plans, the
      Venture has other deferred benefit programs, primarily profit sharing.
      Expenses for these programs for 2003, 2002 and 2001 were $3,259, $8,300
      and $21,790, respectively.

      The Venture's employees are eligible to participate in Schlumberger's
      employee discounted stock purchase plan under which an employee can choose
      each year to have up to 10 percent of their annual earnings withheld to
      purchase Schlumberger common stock. The purchase price of the stock is 85
      percent of the lower of its beginning or end of the plan year market
      price. During the year ended December 31, 2003, Schlumberger recognized
      stock-based compensation expense of approximately $1,536 related to
      Venture employees' participation in the stock purchase plan. As a result,
      the Venture recognized stock-based compensation of $1,536 as selling,
      general and administrative expense during the year ended December 31,
      2003. The expense was treated as a capital investment from Schlumberger
      and was allocated to Schlumberger's owners' net investment balance. Since
      Schlumberger did not record compensation expense for stock purchased by
      employees of the Venture under the stock purchase plan during the years
      ended December 31, 2002 and 2001, no compensation expense has been
      recorded in the Venture's combined financial statements for the years
      ended December 31, 2002 and 2001.

      The Venture's employees may be awarded options to purchase Schlumberger
      common stock on a periodic basis. In January and July 2003, Schlumberger
      granted options to purchase 9,000 and 184,250 shares of Schlumberger
      common stock, respectively, to Venture employees at exercise prices of
      $41.30 and $46.02 per share, respectively. In April 2002, 220,250
      Schlumberger stock options were granted to Venture employees at an
      exercise price of $55.75. In January and October 2001, Schlumberger
      granted options to purchase 177,750 and 33,500 shares of Schlumberger
      common stock, respectively, to Venture employees at exercise prices of
      $77.06 and $46.25 per share, respectively. For all of the stock options
      granted, the exercise price equals the market price of Schlumberger common
      stock on the date of grant. Each option's maximum term is ten years, and
      options generally vest in 20 percent increments over five years. During
      the year ended December 31, 2003, Schlumberger recognized stock-based
      compensation expense of approximately $200 related to options to purchase
      Schlumberger common stock granted to Venture employees. As a result, the
      Venture recognized stock-based compensation of $200 as selling, general
      and administrative expense during the year ended December 31, 2003. The
      expense was treated as a capital investment from Schlumberger and was
      allocated to Schlumberger's owners' net investment balance. Since
      Schlumberger did not record compensation expense for any of the options
      granted to employees of the Venture during the years ended December 31,
      2002 and 2001, no compensation expense has been recorded in the Venture's
      combined financial statements during these years.
