Accounting Policies [Abstract]
Summary of Accounting Policies	2. Summary of Accounting Policies The Consolidated Financial Statements Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable; revenue recognized under the percentage-of-completion method; recoverability of fixed assets, goodwill, intangible assets, Schlumberger Production Management investments and investments in affiliates; income taxes; multiclient seismic data; contingencies and actuarial assumptions for employee benefit plans. Schlumberger bases its estimates on historical experience and 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. Revenue Recognition Schlumberger recognizes revenue based upon purchase orders, contracts or other persuasive evidence of an arrangement with the customer that include fixed or determinable prices provided that collectibility is reasonably assured. Revenue is recognized for services when they are rendered. Revenue is recognized for products upon delivery and when the customer assumes the risks and rewards of ownership. Revenue is recognized for certain long-term construction-type contracts, primarily in the Cameron Group, based on the percentage-of-completion method. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work progresses on each such contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs. Any expected losses on a project are recorded in full in the period in which they become probable. Progress billings are generally issued upon completion of certain phases of work as stipulated in the contract. Revenue in excess of billings is included within Receivables less allowance for doubtful accounts Consolidated Balance Sheet Accounts payable and accrued liabilities Consolidated Balance Sheet Revenue from seismic contract services performed on a dayrate basis is recognized as the service is performed. Revenue from other 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 from sales of completed multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers with access to such data. Revenue is occasionally generated from contractual arrangements that include multiple deliverables. Revenue from these arrangements is recognized as each item is delivered based on its relative fair value, provided that the delivered items have stand-alone value to the customer. 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. Short-term and Fixed Income Investments The Consolidated Balance Sheet Short-term investments Fixed Income Investments, held to maturity Short-term investments For purposes of the Consolidated Statement of Cash Flows Short-term investments Fixed Income Investments, held to maturity at December 31, 2016 of $238 million mature as follows: $225 million in 2018 and $13 million in 2019. Investments in Affiliated Companies Investments in companies 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 in Interest and other income Accumulated other comprehensive loss Equity and cost method investments as well as investments in publicly traded companies are classified as Investments in Affiliated Companies Consolidated Balance Sheet Multiclient Seismic Data Schlumberger’s multiclient library consists of completed and in-process seismic surveys that are licensed on a nonexclusive basis. Schlumberger capitalizes costs directly incurred in acquiring and processing the multiclient seismic data. Such costs are charged to Cost of revenue 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 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. Schlumberger Production Management Schlumberger Production Management (SPM) projects are focused on developing and managing production on behalf of Schlumberger’s clients under long-term agreements. Schlumberger will invest its own services, products and in some cases cash, into the field development activities and operations. Although in certain arrangements Schlumberger is paid for a portion of the services or products it provides, generally Schlumberger will not be paid at the time of providing its services or upon delivery of its products. Instead, Schlumberger is compensated based upon cash flow generated or on a fee-per-barrel basis. This may include certain arrangements whereby Schlumberger is only compensated based upon incremental production it helps deliver above a mutually agreed baseline. Schlumberger capitalizes its cash investments in a project as well as the direct costs associated with providing services or products for which Schlumberger will be compensated when the related production is achieved. Revenue is recognized as the related production is achieved. These capitalized investments are amortized to the Consolidated Statement of Income The unamortized portion of Schlumberger’s investments in SPM projects was $2.458 billion and $1.829 billion at December 31, 2016 and 2015, respectively. These amounts are included within Other Assets Consolidated Balance Sheet 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, 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. By using derivative financial instruments to hedge certain exposures, Schlumberger exposes itself to some credit risk. Schlumberger minimizes this credit risk by entering into transactions with high-quality counterparties, limiting the exposure to each counterparty and monitoring the financial condition of its counterparties. Schlumberger operates in more than 85 countries and as such, its accounts receivable are spread over many countries and customers. The United States, Venezuela and Ecuador each represented approximately 11%, 12% and 12% of Schlumberger’s accounts receivable balance at December 31, 2016. No other country accounted for greater than 10% of Schlumberger’s accounts receivable balance. Schlumberger has continued to experience delays in payment from its national oil company customer in Venezuela. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectibility and performs ongoing credit evaluations of its customers’ financial condition. If the financial condition of its customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required. Earnings per Share The following is a reconciliation from basic to diluted earnings per share from continuing operations of Schlumberger for each of the last three years: (Stated in millions, except per share amounts) Schlumberger Income (Loss) from Continuing Operations Average Shares Outstanding Earnings (Loss) per Share from Continuing Operations 2016: Basic $ (1,687 ) 1,357 $ (1.24 ) Assumed exercise of stock options - - Unvested restricted stock - - Diluted $ (1,687 ) 1,357 $ (1.24 ) 2015: Basic $ 2,072 1,267 $ 1.63 Assumed exercise of stock options - 4 Unvested restricted stock - 4 Diluted $ 2,072 1,275 $ 1.63 2014: Basic $ 5,643 1,295 $ 4.36 Assumed exercise of stock options - 9 Unvested restricted stock - 4 Diluted $ 5,643 1,308 $ 4.31 Employee stock options to purchase 47 million shares of common stock as well as 5 million unvested restricted stock units were outstanding at December 31, 2016, but were not included in the computation of diluted loss per share as their effect, if included, would have been anti-dilutive.

Restructuring And Related Activities [Abstract]
Charges and Credits	3. Charges and Credits Schlumberger recorded the following charges and credits in continuing operations during 2016, 2015 and 2014: 2016 • Schlumberger reduced its headcount during the second quarter of 2016 as a result of persistent unfavorable oil and gas industry market conditions and the expected impact on customer activity levels. Schlumberger recorded a $646 million charge during the second quarter of 2016 associated with this headcount reduction. During the fourth quarter of 2016, Schlumberger decided to further reduce its headcount in order to streamline its support cost structure. Schlumberger recorded an additional $234 million charge during the fourth quarter associated with these actions. Approximately $400 million of the costs remain unpaid as of December 31, 2016. • During the fourth quarter of 2016, Schlumberger recorded $302 million of restructuring charges consisting of the following: $165 million of facility closure costs due to the expected sale of certain owned properties and the termination of certain facility leases; $98 million of asset write-offs associated with exiting certain activities; and $39 million of contract termination costs. • During the fourth quarter of 2016, the Central Bank of Egypt took the decision to float its currency and the Egyptian pound devalued relative to the US dollar. As a result, Schlumberger recorded a $63 million devaluation charge during the fourth quarter of 2016. • As a result of the persistent unfavorable oil and gas industry market conditions that continued to deteriorate in the first half of 2016, and the related impact on first half operating results and expected customer activity levels, Schlumberger determined that the carrying values of certain assets were no longer recoverable and also took certain decisions that resulted in the following impairment and other charges during the second quarter of 2016: - $209 million impairment of pressure pumping equipment in North America. - $165 million impairment of facilities in North America. - $684 million of other fixed asset impairments primarily relating to underutilized equipment. - $616 million write-down of the carrying value of certain inventory to its net realizable value. - $198 million impairment of certain multiclient seismic data, largely related to the US Gulf of Mexico. - $55 million of other restructuring costs. The fair value of the impaired fixed assets and multiclient seismic data was estimated based on the projected present value of future cash flows that these assets are expected to generate. Such estimates included unobservable inputs that required significant judgments. Additional charges may be required in future periods should industry conditions worsen. The above items are classified in Impairments & other Consolidated Statement of Income • In connection with Schlumberger’s April 2016 acquisition of Cameron International Corporation (“Cameron”) (see Note 4 - Acquisitions Merger & integration Consolidated Statement of Income The following is a summary of these charges and credits, of which $3.172 billion were classified as Impairments & other Merger & integration Consolidated Statement of Income (Stated in millions) Pretax Tax Net Workforce reductions $ 880 $ 69 $ 811 Other fixed asset impairments 684 52 632 Inventory write-downs 616 49 567 Amortization of inventory fair value adjustment 299 90 209 Facility closure costs 226 53 173 North America pressure pumping asset impairments 209 67 142 Multiclient seismic data impairment 198 62 136 Facility impairments 165 58 107 Other merger and integration-related 160 28 132 Costs associated with exiting certain activities 98 23 75 Merger-related employee benefits 83 13 70 Currency devaluation loss in Egypt 63 - 63 Other restructuring charges 55 - 55 Professional fees 45 10 35 Contract termination costs 39 9 30 $ 3,820 $ 583 $ 3,237 2015 • Schlumberger reduced its headcount during the first quarter of 2015 as a result of the severe fall in activity in North America, combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. Schlumberger recorded a $390 million charge during the first quarter associated with this headcount reduction as well as an incentivized leave of absence program. Based on the activity outlook for 2016, as well as to further streamline its support structure, Schlumberger decided to further reduce its headcount and expand its incentivized leave of absence program during the fourth quarter of 2015. Schlumberger recorded an additional $530 million charge during the fourth quarter associated with these actions. • As a result of unfavorable oil and gas industry market conditions that continued to deteriorate and their impact on the activity outlook, Schlumberger determined that the carrying values of certain assets were no longer recoverable and also took certain decisions that resulted in the following impairment and restructuring charges during the fourth quarter of 2015: - $776 million of fixed asset impairments primarily related to underutilized pressure pumping and other equipment in North America, as well as certain lower-tier drilling rigs. - $269 million to write-down the carrying value of certain inventory, primarily in North America. - $182 million to reduce the carrying value of an investment in an SPM project to its estimated fair value, as a result of the decline in commodity prices and considering this project is approaching the end of its contractual term. - $177 million associated with certain of Schlumberger’s owned and leased facilities, including the expected sale of certain properties and the termination of certain leases. - $77 million relating to assets that are no longer recoverable as a result of geopolitical issues in certain countries in the Middle East. - $41 million relating to contract termination costs. - $84 million of other charges associated with current market conditions, including $40 million relating to an other-than-temporary impairment of marketable securities and $15 million relating to the impairment of an equity-method investment. Certain of these impairment charges were estimated based on the projected present value of future cash flows, which included unobservable inputs that required significant judgments . • In February 2015, the Venezuelan government replaced the SICAD II exchange rate (described in further detail below) with a new foreign exchange market system known as SIMADI. The SIMADI exchange rate was approximately 192 Venezuelan Bolivares fuertes to the US dollar as of March 31, 2015. As a result, Schlumberger recorded a $49 million devaluation charge during the first quarter of 2015, reflecting the adoption of the SIMADI exchange rate. This change results in a reduction in the US dollar reported amount of local currency denominated revenues, expenses and, consequently, income before taxes and net income in Venezuela. If Schlumberger had applied an exchange rate of 192 Venezuelan Bolivares fuertes to the US dollar throughout 2014, it would have reduced Schlumberger earnings by approximately $0.09 per share. The following is a summary of these charges and credits, all of which were classified as Impairments & other Consolidated Statement of Income (Stated in millions) Pretax Tax Net Workforce reductions $ 920 $ 107 $ 813 Fixed asset impairments 776 141 635 Inventory write-downs 269 27 242 Impairment of SPM project 182 36 146 Facility closures 177 37 140 Geopolitical events 77 - 77 Currency devaluation loss in Venezuela 49 - 49 Contract termination costs 41 2 39 Other 84 7 77 $ 2,575 $ 357 $ 2,218 2014 • During the fourth quarter of 2014, Schlumberger restructured its WesternGeco marine seismic fleet in order to lower its operating costs. Three previous-generation acquisition vessels with lower towing capacity and higher operating costs will be converted to source vessels, allowing for the termination of two third-party source vessel leases and the retirement of two owned source vessels. As a result of this restructuring, Schlumberger performed an impairment test and determined that the carrying values of certain of its vessels exceeded their respective fair values by $590 million. This impairment charge related to the six Explorer-class vessels that were acquired at a premium in Schlumberger’s 2007 acquisition of Eastern Echo Holdings Plc. The fair value of these vessels was estimated primarily based on the replacement cost method, which was largely based on unobservable inputs that required significant judgments. In addition to the $590 million impairment charge relating to these six vessels, Schlumberger also recorded an $85 million impairment charge relating to a seismic intangible asset and $131 million of other charges primarily related to lease termination costs and other seismic assets as a result of the restructuring. Schlumberger did not incur any significant cash expenditures as a result of these charges. • During 2014, Venezuela enacted certain changes to its foreign exchange system such that, in addition to the official rate of 6.3 Venezuelan Bolivares fuertes per US dollar, there were two other legal exchange rates that could be obtained via different exchange rate mechanisms at the time. These changes included the expansion of what was known as the SICAD I auction rate and the introduction of the SICAD II auction process. The SICAD I and SICAD II exchange rates were approximately 11 and 50 Venezuelan Bolivares fuertes to the US dollar, respectively, at December 31, 2014. Schlumberger had historically applied the official exchange rate to remeasure local currency transactions and balances into US dollars. Effective December 31, 2014, Schlumberger concluded that it was appropriate to apply the SICAD II exchange rate as it believed that rate best represented the economics of Schlumberger’s business activity in Venezuela. As a result, Schlumberger recorded a $472 million devaluation charge during the fourth quarter of 2014. • In response to lower commodity pricing and anticipated lower exploration and production spending in 2015, Schlumberger decided during the fourth quarter of 2014 to reduce its overall headcount primarily to better align with anticipated activity levels for 2015. As a result of these reductions, Schlumberger recorded a charge of $296 million in the fourth quarter of 2014. • During the fourth quarter of 2014, Schlumberger determined that, primarily as a result of the recent decline in commodity prices, the carrying value of its investment in an SPM development project in the Eagle Ford Shale was in excess of its fair value. Accordingly, Schlumberger recorded a $199 million impairment charge. The fair value of this investment was estimated based on the projected present value of future cash flows.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions Cameron On April 1, 2016, Schlumberger acquired all of the outstanding shares of Cameron, a leading provider of flow equipment products, systems and services to the oil and gas industry worldwide. The acquisition is expected to create technology-driven growth by integrating Schlumberger reservoir and well technologies with Cameron wellhead and surface equipment, flow control and processing technology. The combination of the two complementary technology portfolios provides the industry’s most comprehensive range of products and services, from exploration to production and integrated pore-to-pipeline solutions that optimize hydrocarbon recovery to deliver reservoir performance. Under the terms of the merger agreement, Cameron became a wholly-owned subsidiary of Schlumberger. Each share of Cameron common stock issued and outstanding immediately prior to the effective time of the merger was converted into the right to receive 0.716 shares of Schlumberger stock and $14.44 in cash. Calculation of Consideration Transferred The following details the fair value of the consideration transferred to effect the acquisition of Cameron: (stated in millions, except exchange ratio and per share amounts) Equity consideration: Number of shares of Cameron stock outstanding 192 Exchange ratio 0.716 Schlumberger shares of common stock issued 138 Schlumberger closing stock share price on April 1, 2016 $ 72.12 Equity consideration $ 9,924 Cash consideration: Number of shares of Cameron stock outstanding 192 Cash consideration per Cameron share $ 14.44 Cash consideration 2,776 Other: Fair value of replacement equity awards 103 Total fair value of the consideration transferred $ 12,803 Certain amounts reflect rounding adjustments Preliminary Allocation of Consideration Transferred to Net Assets Acquired The following amounts represent the preliminary estimates of the fair value of assets acquired and liabilities assumed in the merger. The final determination of fair value for certain assets and liabilities will be completed as soon as the information necessary to complete the analysis is obtained. These amounts, which are not expected to differ materially from current estimates, will be finalized in the first quarter of 2017.

Businesses acquired from Cameron contributed revenues of approximately $4 billion and pretax operating income of approximately $0.7 billion for the period from April 1, 2016 through December 31, 2016. The following supplemental pro forma results of operations assume that Cameron had been acquired on January 1, 2015. The supplemental pro forma financial information was prepared based on the historical financial information of Schlumberger and Cameron and has been adjusted to give effect to pro forma adjustments that are both directly attributable to the transaction and factually supportable. The pro forma amounts reflect certain adjustments to amortization expense, interest expense and income taxes resulting from purchase accounting. The pro forma results for the year ended December 31, 2016 reflect adjustments to exclude after-tax merger and integration costs of $285 million and after-tax charges relating to the amortization of the inventory fair value adjustment of $209 million. As required by generally accepted accounting principles, the pro forma results for the year ended December 31, 2015 have been adjusted to include after-tax adjustments for merger and integration costs of $285 million and the after-tax charges relating to the amortization of the inventory fair value adjustment of $209 million. The supplemental pro forma financial information presented below is unaudited and does not include any anticipated cost savings or the expected realization of other synergies associated with this transaction. Accordingly, this supplemental pro forma financial information is presented for informational purposes only and is not necessarily indicative of what the actual results of operations of the combined company would have been had the acquisition occurred on January 1, 2015, nor is it indicative of future results of operations. (Stated in millions, except per share amounts) 2016 2015 Revenue $ 29,438 $ 44,306 Net income (loss) attributable to Schlumberger $ (1,419 ) $ 2,000 Diluted earnings (loss) per share $ (1.02 ) $ 1.42 Other Schlumberger made other acquisitions and investments for cash payments, net of cash acquired, of $407 million during 2016, $443 million during 2015, and $1.008 billion during 2014. Additionally, during 2014 Schlumberger issued 2.1 million shares of its common stock, valued at $213 million, in connection with an acquisition. None of these transactions were significant to Schlumberger’s consolidated financial statements, either individually or in the aggregate.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	11. Derivative Instruments and Hedging Activities Schlumberger is exposed to market risks related to fluctuations in interest rates and foreign currency exchange rates. To mitigate these risks, Schlumberger utilizes derivative instruments. Schlumberger does not enter into derivative transactions for speculative purposes. Interest Rate Risk Schlumberger is subject to interest rate risk on its debt and its investment portfolio. Schlumberger maintains an interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its investment portfolio, and occasionally interest rate swaps, to mitigate the exposure to changes in interest rates. During 2013, Schlumberger entered into a cross currency swap for a notional amount of €0.5 billion in order to hedge changes in the fair value of Schlumberger’s €0.5 billion 1.50% Guaranteed Notes due 2019. Under the terms of this swap, Schlumberger will receive interest at a fixed rate of 1.50% on the euro notional amount and pay interest at a floating rate of three-month LIBOR plus approximately 64 basis points on the US dollar notional amount. This cross currency swap is designated as a fair value hedge of the underlying debt. This derivative instrument is marked to market with gains and losses recognized currently in income to largely offset the respective gains and losses recognized on changes in the fair value of the hedged debt. At December 31, 2016, Schlumberger had fixed rate debt aggregating $14.1 billion and variable rate debt aggregating $5.5 billion, after taking into account the effect of the swap. Short-term investments and , , totaled $6.6 billion at December 31, 2016. The carrying value of these investments approximated fair value, which was estimated using quoted market prices for those or similar investments. Foreign Currency Exchange Rate Risk As a multinational company, Schlumberger conducts its business in over 85 countries. Schlumberger’s functional currency is primarily the US dollar. Approximately 77% of Schlumberger’s revenues in 2016 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 (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar–reported expenses will increase (decrease). Schlumberger is exposed to risks on future cash flows to the extent that the local currency is not the functional currency and expenses denominated in local currency are not equal to revenues denominated in local currency. Schlumberger is also exposed to risks on future cash flows relating to certain of its fixed rate debt that is denominated in currencies other than the functional currency. Schlumberger uses foreign currency forward contracts to provide a hedge against a portion of these cash flow risks. These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet Accumulated Other Comprehensive Loss. Accumulated Other Comprehensive Loss At December 31, 2016, Schlumberger recognized a cumulative net $19 million loss in Accumulated other comprehensive loss Schlumberger is exposed to changes in the fair value of assets and liabilities that are denominated in currencies other than the functional currency. While Schlumberger uses foreign currency forward contracts to economically hedge this exposure as it relates to certain currencies, these contracts are not designated as hedges for accounting purposes. Instead the fair value of the contracts are recorded on the Consolidated Balance Sheet Consolidated Statement of Income Consolidated Statement of Income Charges and Credits At December 31, 2016, contracts were outstanding for the US dollar equivalent of $5.5 billion in various foreign currencies, of which $1.1 billion relates to hedges of debt denominated in currencies other than the functional currency.

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: 2016 2015 2014 Dividend yield 2.7 % 2.3 % 1.6 % Expected volatility 30 % 36 % 37 % Risk-free interest rate 1.7 % 1.7 % 2.2 % Expected option life in years 7.0 7.0 7.0 Weighted-average fair value per share $ 17.45 $ 25.96 $ 34.20 The following table summarizes information related to options outstanding and options exercisable as of December 31, 2016: (Shares stated in thousands) Options Outstanding Options Exercisable Weighted- Average Remaining Weighted- Weighted- Options Contractual Life Average Options Average Exercise prices range Outstanding (in years) Exercise Price Exercisable Exercise Price $37.85 - $67.87 6,526 5.2 $ 55.58 4,524 $ 52.78 $68.51 - $72.00 7,501 5.3 $ 70.08 5,761 $ 69.79 $72.11 - $79.85 8,767 6.3 $ 74.01 5,108 $ 72.82 $80.53 - $84.93 12,375 5.9 $ 82.72 7,093 $ 84.17 $88.61 - $114.83 11,333 6.9 $ 95.37 4,859 $ 95.89 46,502 6.0 $ 78.31 27,345 $ 75.91 The weighted-average remaining contractual life of stock options exercisable as of December 31, 2016 was 4.5 years.

The total intrinsic value of options exercised during the years ended December 31, 2016, 2015 and 2014 was $45 million, $62 million and $314 million, respectively. Restricted Stock Schlumberger grants performance share units to certain executives. The number of shares earned is determined at the end of each performance period, which is generally three years, based on Schlumberger’s achievement of certain predefined targets as defined in the underlying performance share unit agreement. In the event Schlumberger exceeds the predefined target, shares for up to the maximum of 250% of the target award may be granted. In the event Schlumberger falls below the predefined target, a reduced number of shares may be granted. If Schlumberger falls below the threshold award performance level, no shares will be granted. As of December 31, 2016, 1.0 million performance share units All other restricted stock awards generally vest at the end of three years. Restricted stock awards do not pay dividends or have voting rights prior to vesting. Accordingly, the fair value of a restricted stock award is the quoted market price of Schlumberger’s stock on the date of grant less the present value of the expected dividends not received prior to vesting.

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: 2016 2015 2014 Dividend yield 2.7 % 2.3 % 1.6 % Expected volatility 25 % 27 % 19 % Risk-free interest rate 0.5 % 0.2 % 0.1 % Weighted-average fair value per share $ 10.37 $ 12.45 $ 12.67 Total Stock-based Compensation Expense The following summarizes stock-based compensation expense recognized in income: (Stated in millions) 2016 2015 2014 Stock options $ 175 $ 176 $ 177 Restricted stock 47 107 114 DSPP 45 43 38 $ 267 $ 326 $ 329 At December 31, 2016, there was $480 million of total unrecognized compensation cost related to nonvested stock-based compensation arrangements, of which $212 million is expected to be recognized in 2017, $157 million in 2018, $74 million in 2019, $31 million in 2020 and $6 million in 2021. As of December 31, 2016, approximately 20 million shares of Schlumberger common stock were available for future grants under Schlumberger’s stock-based compensation programs.

Income (loss) from continuing operations before taxes subject to United States and non-United States income taxes were as follows: (Stated in millions) 2016 2015 2014 United States $ (3,103 ) $ (691 ) $ 1,990 Outside United States 1,198 3,572 5,649 $ (1,905 ) $ 2,881 $ 7,639 Schlumberger recorded pretax charges of $3.820 billion in 2016 ($1.848 billion in the US and $1.972 billion outside of the US); $2.575 billion in 2015 ($883 million in the US and $1.692 billion outside the US); and $1.773 billion in 2014 ($289 million in the US and $1.484 billion outside the US). These charges and credits are included in the table above and are more fully described in Note 3 – Charges and Credits The components of net deferred tax assets (liabilities) were as follows: (Stated in millions) 2016 2015 Postretirement benefits $ 253 $ 266 Intangible assets (2,869 ) (1,418 ) Investments in non-US subsidiaries (271 ) (152 ) Fixed assets, net (79 ) (176 ) Inventories 248 159 Other, net 838 454 $ (1,880 ) $ (867 ) The above deferred tax balances at December 31, 2016 and 2015 were net of valuation allowances relating to net operating losses in certain countries of $186 million and $162 million, respectively. Schlumberger generally does not provide for taxes relating to undistributed earnings because such earnings would not be taxable when remitted or they are considered to be indefinitely reinvested. In connection with Schlumberger’s 2016 acquisition of Cameron, certain non-US subsidiaries of Cameron are now either wholly or partially owned by a US subsidiary of Schlumberger. Undistributed earnings of these non-US subsidiaries that are indefinitely invested outside the US are approximately $3 billion. Such earnings would be subject to US taxes if they were to be repatriated to the US. However, determination of the unrecognized deferred tax liability that would be incurred if such amounts were repatriated to the US is not practicable.

Schlumberger’s tax filings are subject to regular audit by the tax authorities. These audits may result in assessments for additional taxes that are resolved with the tax authorities or, potentially, through the courts. Tax liabilities are recorded based on estimates of additional taxes that will be due upon the conclusion of these audits. Due to the uncertain and complex application of tax regulations, the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. A reconciliation of the beginning and ending amount of liabilities associated with uncertain tax positions for the years ended December 31, 2016, 2015 and 2014 is as follows: (Stated in millions) 2016 2015 2014 Balance at beginning of year $ 1,285 $ 1,402 $ 1,452 Additions based on tax positions related to the current year 70 140 154 Additions for tax positions of prior years 119 136 96 Additions related to acquisitions 127 5 43 Impact of changes in exchange rates (25 ) (78 ) (62 ) Settlements with tax authorities (45 ) (99 ) (27 ) Reductions for tax positions of prior years (85 ) (203 ) (212 ) Reductions due to the lapse of the applicable statute of limitations (27 ) (18 ) (42 ) Balance at end of year $ 1,419 $ 1,285 $ 1,402 The amounts above exclude accrued interest and penalties of $178 million, $176 million and $243 million at December 31, 2016, 2015 and 2014, respectively. Schlumberger classifies interest and penalties relating to uncertain tax positions within Taxes on income (loss) Consolidated Statement of Income 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: Brazil 2011 - 2016 Canada 2009 - 2016 Ecuador 2013 - 2016 Mexico 2010 - 2016 Norway 2013 - 2016 Russia 2013 - 2016 Saudi Arabia 2004 - 2016 United Kingdom 2014 - 2016 United States 2014 - 2016 In certain of the jurisdictions noted above, Schlumberger operates through more than one legal entity, each of which may have 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.

Contingencies	16. Contingencies Schlumberger and its subsidiaries are party to various legal proceedings from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote. However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.

Compensation And Retirement Disclosure [Abstract]
Pension and Other Benefit Plans	18. Pension and Other Benefit Plans Pension Plans Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired prior to October 1, 2004. The benefits are based on years of service and compensation, on a career-average pay basis. In addition to the US defined benefit pension plans, Schlumberger sponsors several other international defined benefit pension plans. The most significant of these international plans are the International Staff Pension Plan and the UK pension plan (collectively, the “International plans”). The International Staff Pension Plan covers certain international employees hired prior to July 1, 2014 and is based on years of service and compensation on a career-average pay basis. The UK plan covers employees hired prior to April 1, 1999, and is based on years of service and compensation, on a final salary basis. The weighted-average assumed discount rate, compensation increases and the expected long-term rate of return on plan assets used to determine the net pension cost for the US and International plans were as follows: US International 2016 2015 2014 2016 2015 2014 Discount rate 4.50 % 4.15 % 4.85 % 4.36 % 4.07 % 4.76 % Compensation increases 4.00 % 4.00 % 4.00 % 4.80 % 4.79 % 4.80 % Return on plan assets 7.25 % 7.25 % 7.25 % 7.40 % 7.40 % 7.50 % Net pension cost for 2016, 2015 and 2014 included the following components: (Stated in millions) US International 2016 2015 2014 2016 2015 2014 Service cost - benefits earned during the period $ 62 $ 86 $ 72 $ 110 $ 167 $ 126 Interest cost on projected benefit obligation 177 170 164 311 297 288 Expected return on plan assets (235 ) (229 ) (208 ) (517 ) (498 ) (450 ) Amortization of prior service cost 12 12 12 122 121 120 Amortization of net loss 79 123 82 78 170 94 $ 95 $ 162 $ 122 $ 104 $ 257 $ 178 The weighted-average assumed discount rate and compensation increases used to determine the projected benefit obligations for the US and International plans were as follows: US International 2016 2015 2016 2015 Discount rate 4.20 % 4.50 % 4.13 % 4.36 % Compensation increases 4.00 % 4.00 % 4.81 % 4.80 % The changes in the projected benefit obligation, plan assets and funded status of the plans were as follows: (Stated in millions) US International 2016 2015 2016 2015 Change in Projected Benefit Obligations Projected benefit obligation at beginning of year $ 4,025 $ 4,137 $ 7,340 $ 7,249 Service cost 62 86 110 167 Interest cost 177 170 311 297 Contribution by plan participants - - 117 143 Actuarial (gains) losses 137 (205 ) 477 (203 ) Currency effect - - (290 ) (66 ) Benefits paid (183 ) (163 ) (272 ) (247 ) Other 22 - - - Projected benefit obligation at end of year $ 4,240 $ 4,025 $ 7,793 $ 7,340 Change in Plan Assets Plan assets at fair value at beginning of year $ 3,467 $ 3,549 $ 6,832 $ 6,830 Actual return on plan assets 320 (1 ) 715 (5 ) Currency effect - - (318 ) (69 ) Company contributions 4 82 130 198 Contributions by plan participants - - 107 125 Benefits paid (183 ) (163 ) (272 ) (247 ) Other 17 - - - Plan assets at fair value at end of year $ 3,625 $ 3,467 $ 7,194 $ 6,832 Unfunded Liability $ (615 ) $ (558 ) $ (599 ) $ (508 ) Amounts Recognized in Balance Sheet Postretirement Benefits $ (615 ) $ (558 ) $ (724 ) $ (657 ) Other Assets - - 125 149 $ (615 ) $ (558 ) $ (599 ) $ (508 ) Amounts Recognized in Accumulated Other Comprehensive Loss Actuarial losses $ 982 $ 1,008 $ 1,644 $ 1,474 Prior service cost 42 54 114 235 $ 1,024 $ 1,062 $ 1,758 $ 1,709 Accumulated benefit obligation $ 3,999 $ 3,763 $ 7,454 $ 6,913 The unfunded liability 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 accumulated benefit obligation represents the actuarial present value of benefits based on employee service and compensation, but does not include an assumption about future compensation levels. The weighted-average allocation of plan assets and the target allocations by asset category are as follows: US International Target 2016 2015 Target 2016 2015 Equity securities 37 - 56 % 52 % 52 % 45 - 71 % 64 % 64 % Debt securities 35 - 62 37 36 20 - 35 25 27 Cash and cash equivalents 0 - 3 2 2 0 - 5 2 2 Alternative investments 0 - 10 9 10 0 - 25 9 7 100 % 100 % 100 % 100 % 100 % 100 % Asset performance is monitored frequently with an overall expectation that plan assets will meet or exceed the weighted index of its target asset allocation and component benchmark over rolling five-year periods. The expected rate of return on assets assumptions reflect the long-term average rate of earnings expected on funds invested or to be invested. The assumptions have been determined based on expectations regarding future rates of return for the portfolio considering the asset allocation and related historical rates of return. The appropriateness of the assumptions is reviewed annually. The fair value of Schlumberger’s pension plan assets at December 31, 2016 and 2015, by asset category, is presented below and was determined based on valuation techniques categorized as follows: Level One: The use of quoted prices in active markets for identical instruments. Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data. Level Three: The use of significant unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing.

(b) International equities are invested in companies that are traded on exchanges outside the US and are well-diversified by industry sector, country and equity style. Active and passive strategies are employed. The vast majority of the investments are made in companies in developed markets with a small percentage in emerging markets. (c) Corporate bonds consist primarily of investment grade bonds from diversified industries. (d) Government and government-related debt securities are comprised primarily of inflation-protected US treasuries and, to a lesser extent, other government-related securities. (e) Collateralized mortgage obligations and mortgage backed-securities are debt obligations that represent claims to the cash flows from pools of mortgage loans, which are purchased from banks, mortgage companies, and other originators and then assembled into pools by governmental, quasi-governmental and private entities. (f) Private equity includes investments in several fund of funds limited partnerships. (g) Real estate primarily includes investments in real estate limited partnerships, concentrated in commercial real estate. Schlumberger’s funding policy 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. Schlumberger expects to contribute approximately $200 million to its postretirement benefit plans in 2017, subject to market and business conditions. Postretirement Benefits Other Than Pensions Schlumberger provides certain healthcare benefits to certain former US employees who have retired. Effective April 1, 2015, Schlumberger changed the way it provides healthcare coverage to certain retirees who are age 65 and over. Under the amended plan, these retirees transferred to individual coverage under the Medicare Exchange. Schlumberger subsidizes the cost of the program by providing these retirees with a Health Reimbursement Account. The annual subsidy may be increased based on medical cost inflation, but it will not be increased by more than 5% in any given year. The actuarial assumptions used to determine the accumulated postretirement benefit obligation and net periodic benefit cost for the US postretirement medical plan were as follows: Benefit Obligations Net Periodic Benefit At December 31, Cost for the Year 2016 2015 2016 2015 2014 Discount rate 4.20 % 4.50 % 4.50 % 4.15 % 4.85 % Return on plan assets - - 7.00 % 7.00 % 7.00 % Current medical cost trend rate 7.25 % 7.50 % 7.50 % 7.00 % 7.25 % Ultimate medical cost trend rate 5.00 % 5.00 % 5.00 % 5.00 % 5.00 % Year that the rate reaches the ultimate trend rate 2026 2023 2026 2023 2023 The net periodic benefit cost (credit) for the US postretirement medical plan included the following components: (Stated in millions) 2016 2015 2014 Service cost $ 30 $ 42 $ 43 Interest cost 47 48 60 Expected return on plan assets (57 ) (52 ) (45 ) Amortization of prior service credit (32 ) (32 ) (4 ) Amortization of net loss - 13 1 $ (12 ) $ 19 $ 55 The changes in the accumulated postretirement benefit obligation, plan assets and funded status were as follows: (Stated in millions) 2016 2015 Change in Projected Benefit Obligations Benefit obligation at beginning of year $ 1,103 $ 1,221 Service cost 30 42 Interest cost 47 48 Contribution by plan participants 8 7 Actuarial gains (32 ) (168 ) Benefits paid (48 ) (47 ) Benefit obligation at end of year $ 1,108 $ 1,103 Change in Plan Assets Plan assets at fair value at beginning of year $ 884 $ 854 Actual return on plan assets 68 4 Company contributions 40 66 Contributions by plan participants 8 7 Benefits paid (48 ) (47 ) Plan assets at fair value at end of year $ 952 $ 884 Unfunded Liability $ (156 ) $ (219 ) Amounts Recognized in Accumulated Other Comprehensive Loss Actuarial losses $ 62 $ 106 Prior service credit (243 ) (275 ) $ (181 ) $ (169 ) The unfunded liability is included in Postretirement Benefits Consolidated Balance Sheet The assets of the US postretirement medical plan are invested 63% in equity securities and 37% in debt securities at December 31, 2016. The fair value of these assets was primarily determined based on Level Two valuation techniques. Assumed health care cost trend rates have a significant effect on the amounts reported for the US postretirement medical plan. A one percentage point change in assumed health care cost trend rates would have the following effects: (Stated in millions) One Percentage One Percentage Point Increase Point Decrease Effect on total service and interest cost components $ 3 $ (3 ) Effect on accumulated postretirement benefit obligation $ 34 $ (30 ) Other Information The expected benefits to be paid under the US and International pension plans as well as the postretirement medical plan are as follows: (Stated in millions) Pension Benefits Postretirement US International Medical Plan 2017 $ 189 $ 258 $ 52 2018 $ 195 $ 273 $ 54 2019 $ 201 $ 286 $ 55 2020 $ 208 $ 300 $ 59 2021 $ 215 $ 313 $ 60 2022-2026 $ 1,188 $ 1,784 $ 325 Included in Accumulated other comprehensive loss Accumulated other comprehensive loss (Stated in millions) Postretirement Pension Plans Medical Plan Net actuarial losses $ 157 $ - Prior service cost (credit) $ 109 $ (29 ) In addition to providing defined pension benefits and a postretirement medical plan, Schlumberger and its subsidiaries have other deferred benefit programs, primarily profit sharing and defined contribution pension plans. Expenses for these programs were $445 million, $565 million and $749 million in 2016, 2015 and 2014, respectively.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	20. Discontinued Operations During 2013, Schlumberger completed the wind down of its operations in Iran and, therefore, classified the historical results of this business as a discontinued operation. In 2009, the US Department of Justice began an investigation into past violations of US sanctions regarding Schlumberger’s historical operations in Iran and Sudan that occurred between 2004 and 2010. During the second quarter of 2014, Schlumberger increased its accrual for this contingency and recorded a $205 million charge, which was reflected within Loss from discontinued operations Consolidated Statement of Income During 2015, Schlumberger resolved this investigation and a non-US subsidiary of Schlumberger pleaded guilty to one criminal count of conspiracy to violate the International Emergency Economic Powers Act. Under the terms of the plea agreement, Schlumberger paid approximately $233 million in fines, penalties and assessments during the second quarter of 2015, which had been previously accrued. This payment is reflected within Cash flows used in discontinued operations – operating activities Consolidated Statement of Cash Flows.

Summary of Accounting Policies

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable; revenue recognized under the percentage-of-completion method; recoverability of fixed assets, goodwill, intangible assets, Schlumberger Production Management investments and investments in affiliates; income taxes; multiclient seismic data; contingencies and actuarial assumptions for employee benefit plans. Schlumberger bases its estimates on historical experience and 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.
Revenue Recognition	Revenue Recognition Schlumberger recognizes revenue based upon purchase orders, contracts or other persuasive evidence of an arrangement with the customer that include fixed or determinable prices provided that collectibility is reasonably assured. Revenue is recognized for services when they are rendered. Revenue is recognized for products upon delivery and when the customer assumes the risks and rewards of ownership. Revenue is recognized for certain long-term construction-type contracts, primarily in the Cameron Group, based on the percentage-of-completion method. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work progresses on each such contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs. Any expected losses on a project are recorded in full in the period in which they become probable. Progress billings are generally issued upon completion of certain phases of work as stipulated in the contract. Revenue in excess of billings is included within Receivables less allowance for doubtful accounts Consolidated Balance Sheet Accounts payable and accrued liabilities Consolidated Balance Sheet Revenue from seismic contract services performed on a dayrate basis is recognized as the service is performed. Revenue from other 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 from sales of completed multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers with access to such data. Revenue is occasionally generated from contractual arrangements that include multiple deliverables. Revenue from these arrangements is recognized as each item is delivered based on its relative fair value, provided that the delivered items have stand-alone value to the customer. 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.
Short-term and Fixed Income Investments	Short-term and Fixed Income Investments The Consolidated Balance Sheet Short-term investments Fixed Income Investments, held to maturity Short-term investments For purposes of the Consolidated Statement of Cash Flows Short-term investments Fixed Income Investments, held to maturity at December 31, 2016 of $238 million mature as follows: $225 million in 2018 and $13 million in 2019.
Investments in Affiliated Companies	Investments in Affiliated Companies Investments in companies 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 in Interest and other income Accumulated other comprehensive loss Equity and cost method investments as well as investments in publicly traded companies are classified as Investments in Affiliated Companies Consolidated Balance Sheet
Multiclient Seismic Data	Multiclient Seismic Data Schlumberger’s multiclient library consists of completed and in-process seismic surveys that are licensed on a nonexclusive basis. Schlumberger capitalizes costs directly incurred in acquiring and processing the multiclient seismic data. Such costs are charged to Cost of revenue 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 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.
Schlumberger Production Management	Schlumberger Production Management Schlumberger Production Management (SPM) projects are focused on developing and managing production on behalf of Schlumberger’s clients under long-term agreements. Schlumberger will invest its own services, products and in some cases cash, into the field development activities and operations. Although in certain arrangements Schlumberger is paid for a portion of the services or products it provides, generally Schlumberger will not be paid at the time of providing its services or upon delivery of its products. Instead, Schlumberger is compensated based upon cash flow generated or on a fee-per-barrel basis. This may include certain arrangements whereby Schlumberger is only compensated based upon incremental production it helps deliver above a mutually agreed baseline. Schlumberger capitalizes its cash investments in a project as well as the direct costs associated with providing services or products for which Schlumberger will be compensated when the related production is achieved. Revenue is recognized as the related production is achieved. These capitalized investments are amortized to the Consolidated Statement of Income The unamortized portion of Schlumberger’s investments in SPM projects was $2.458 billion and $1.829 billion at December 31, 2016 and 2015, respectively. These amounts are included within Other Assets Consolidated Balance Sheet
Concentration of Credit Risk	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, 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. By using derivative financial instruments to hedge certain exposures, Schlumberger exposes itself to some credit risk. Schlumberger minimizes this credit risk by entering into transactions with high-quality counterparties, limiting the exposure to each counterparty and monitoring the financial condition of its counterparties. Schlumberger operates in more than 85 countries and as such, its accounts receivable are spread over many countries and customers. The United States, Venezuela and Ecuador each represented approximately 11%, 12% and 12% of Schlumberger’s accounts receivable balance at December 31, 2016. No other country accounted for greater than 10% of Schlumberger’s accounts receivable balance. Schlumberger has continued to experience delays in payment from its national oil company customer in Venezuela. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectibility and performs ongoing credit evaluations of its customers’ financial condition. If the financial condition of its customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.

[1]	Schlumberger recorded an adjustment of $299 million to write-up the acquired inventory to its estimated fair value. Schlumberger’s 2016 cost of sales reflected this increased valuation.
[2]	In connection with the merger, Schlumberger assumed all of the debt obligations of Cameron, including its $2.75 billion of fixed rate notes. Schlumberger recorded a $244 million adjustment to increase the carrying amount of these notes to their estimated fair value. This adjustment is being amortized as a reduction of interest expense over the remaining term of the respective obligations.
[3]	In connection with the acquisition accounting, Schlumberger provided deferred taxes related to, among other items, the estimated fair value adjustments for acquired inventory, intangible assets and assumed debt obligations.
[4]	The goodwill recognized is primarily attributable to expected synergies that will result from combining the operations of Schlumberger and Cameron, as well as intangible assets which do not qualify for separate recognition. The amount of goodwill that is deductible for income tax purposes is not significant.
[5]	Prior to the completion of the merger, Cameron and Schlumberger operated OneSubsea, a joint venture that manufactured and developed products, systems and services for the subsea oil and gas market, which was 40% owned by Schlumberger and 60% owned by Cameron. OneSubsea is now owned 100% by Schlumberger. As a result of obtaining control of this joint venture, Schlumberger was required to remeasure its previously held equity interest in the joint venture to its acquisition-date fair value. Schlumberger determined that the estimated fair value of its previously held equity interest approximated its carrying value. Accordingly, Schlumberger did not recognize any gain or loss on this transaction.

Retirement coverage plan, description	Effective April 1, 2015, Schlumberger changed the way it provides healthcare coverage to certain retirees who are age 65 and over. Under the amended plan, these retirees transferred to individual coverage under the Medicare Exchange. Schlumberger subsidizes the cost of the program by providing these retirees with a Health Reimbursement Account. The annual subsidy may be increased based on medical cost inflation, but it will not be increased by more than 5% in any given year.
