Restructuring And Related Activities [Abstract]
Charges and Credits	2. Charges and Credits Schlumberger recorded the following charges and credits during the first nine months of 2016: Third quarter of 2016: • In connection with Schlumberger’s acquisition of Cameron International Corporation (“Cameron”) (see Note 4 – Acquisition of Cameron Merger & integration in the Consolidated Statement of Income. Second 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 the 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: - $646 million of severance costs associated with headcount reductions. - $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 other 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 costs, primarily relating to facility closure 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 acquisition of Cameron, Schlumberger recorded $335 million of charges consisting of the following: $150 million relating to the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value; $47 million relating to employee benefits for change-in-control arrangements and retention bonuses; $45 million of transaction costs, including advisory and legal fees; $40 million of facility closure costs, and $53 million of other merger and integration-related costs. These amounts are classified in Merger & integration Consolidated Statement of Income The following is a summary of the charges and credits recorded during the first nine months of 2016: (Stated in millions) Pretax Tax Net Workforce reduction $ 646 $ 63 $ 583 North America pressure pumping asset impairments 209 67 142 Facilities impairments 165 58 107 Other fixed asset impairments 684 52 632 Inventory write-downs 616 49 567 Multiclient seismic data impairment 198 62 136 Other restructuring charges 55 - 55 Amortization of inventory fair value adjustment 299 90 209 Merger-related employee benefits 93 17 76 Professional fees 45 10 35 Facility closure costs 51 13 38 Other merger and integration-related 83 11 72 $ 3,144 $ 492 $ 2,652 There were no charges or credits recorded during the first quarter of 2016. Schlumberger recorded the following charges and credits 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 decided to reduce its headcount during the first quarter of 2015. Schlumberger recorded a $390 million charge associated with this headcount reduction as well as an incentivized leave of absence program. • In February 2015, the Venezuelan government replaced the SICAD II exchange rate 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 resulted 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. The following is a summary of these charges, all of which were classified as Impairments & other Consolidated Statement of Income (Stated in millions) Pretax Tax Net Workforce reduction $ 390 $ 56 $ 334 Currency devaluation loss in Venezuela 49 - 49 $ 439 $ 56 $ 383 There were no charges or credits recorded during the second and third quarters of 2015.

Acquisition of Cameron

Business Combinations [Abstract]
Acquisition of Cameron	4. Acquisition of 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 represents 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 may differ materially from these preliminary estimates, will be finalized as soon as practicable, but no later than one year from the acquisition date.

Businesses acquired from Cameron contributed revenues of approximately $3 billion and pretax operating income of $0.5 billion for the period from April 1, 2016 through September 30, 2016. The following supplemental pro forma results of operations assume that Cameron had been acquired as of 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 three months ended September 30, 2016 reflect adjustments to exclude after-tax merger and integration costs of $73 million and after-tax charges relating to the amortization of the inventory fair value adjustment of $104 million. The pro forma results for the nine months ended September 30, 2016 reflect adjustments to exclude after-tax merger and integration costs of $221 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 three months ended September 30, 2015 have been adjusted to include $73 million of after-tax merger and integration charges. The pro forma results for the nine months ended September 30, 2015 have been adjusted to include after-tax adjustments for merger and integration costs of $221 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 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.

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 foreign currency exchange rates and interest 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 the fourth quarter of 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 receives interest at a fixed rate of 1.50% on the euro notional amount and pays 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 in income to largely offset the respective gains and losses recognized on changes in the fair value of the hedged debt. At September 30, 2016, Schlumberger had fixed rate debt of $14.4 billion and variable rate debt of $6.9 billion after taking into account the effect of the swap. Short-term investments and , totaled $7.7 billion at September 30, 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. 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 and foreign currency options 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 September 30, 2016, Schlumberger recognized a cumulative net $16 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 and foreign currency options 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 is recorded on the Consolidated Balance Sheet, Consolidated Statement of Income At September 30, 2016, contracts were outstanding for the US dollar equivalent of $4.6 billion in various foreign currencies, of which $0.7 billion related to hedges of debt denominated in currencies other than the functional currency. The fair values of outstanding derivative instruments were as follows: (Stated in millions) Fair Value of Derivatives Consolidated Balance Sheet Classification Sept. 30, Dec. 31, 2016 2015 Derivative Assets Derivatives designated as hedges: Foreign exchange contracts $ 8 $ 4 Other current assets Foreign exchange contracts - 6 Other Assets $ 8 $ 10 Derivatives not designated as hedges: Foreign exchange contracts $ 40 $ 15 Other current assets Foreign exchange contracts 1 - Other Assets $ 49 $ 25 Derivative Liabilities Derivatives designated as hedges: Foreign exchange contracts $ 23 $ 37 Accounts payable and accrued liabilities Foreign exchange contracts 1 3 Other Liabilities Cross currency swap 32 22 Other Liabilities $ 56 $ 62 Derivatives not designated as hedges: Foreign exchange contracts $ 38 $ 25 Accounts payable and accrued liabilities Foreign exchange contracts 1 - Other Liabilities $ 95 $ 87 The fair value of all outstanding derivatives was determined using a model with inputs that are observable in the market or that can be derived from, or corroborated by, observable data.

Contingencies	13. 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 proceedings is remote.

[1]	Schlumberger recorded an adjustment of $299 million to write-up the acquired inventory to its estimated fair value. Schlumberger’s cost of sales reflected this increased valuation as this inventory was sold.
[2]	In connection with the merger, Schlumberger assumed all of the debt obligations of Cameron, including their $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.
