Restructuring And Related Activities [Abstract]
Charges and Credits	2. Charges and Credits Schlumberger recorded the following charges and credits during the first six months of 2017: Second quarter 2017: • During the second quarter of 2017, Schlumberger entered into a financing agreement with its primary customer in Venezuela. This agreement resulted in the exchange of $700 million of outstanding accounts receivable for a promissory note with a three-year term that bears interest at the rate of 6.50% per annum. Schlumberger recorded this note at its estimated fair value on the date of the exchange, which resulted in a pretax and after-tax charge of $460 million. Schlumberger is accounting for the promissory note as an available-for-sale security reported at fair value in Other Assets, Accumulated other comprehensive loss During the second quarter of 2017, Schlumberger also entered into discussions with another customer relating to certain of its outstanding accounts receivable. As a result of these ongoing discussions, Schlumberger recorded a pretax charge of $50 million ($38 million after taxes and noncontrolling interests) to adjust these receivables to their estimated net realizable value. These charges are classified in Impairments & other Consolidated Statement of Income (Loss). • In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron Merger & integration Consolidated Statement of Income (Loss) First quarter of 2017: • In connection with Schlumberger’s acquisition of Cameron (See Note 4 – Acquisition of Cameron Merger & integration Consolidated Statement of Income (Loss) The following is a summary of the charges and credits recorded during the first six months of 2017: (Stated in millions) Noncontrolling Pretax Tax Interests Net Promissory note fair value adjustment and other $ 510 $ - $ 12 $ 498 Merger & integration 164 31 - 133 $ 674 $ 31 $ 12 $ 631 Schlumberger recorded the following charges and credits during the 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 first-half operating results and expected customer activity levels, Schlumberger determined that the carrying values of certain assets were no longer recoverable and took certain decisions that resulted in the following impairments and other charges: - $646 million of severance costs associated with further 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 (Loss) • In connection with Schlumberger’s acquisition of Cameron (see Note 4 – Acquisition of Cameron Merger & integration Consolidated Statement of Income (Loss), Cost of sales Consolidated Statement of Income (Loss) Merger & integration Cost of sales The following is a summary of the charges and credits recorded during the second quarter of 2016: (Stated in millions) Pretax Tax Net Impairments & other 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 Merger & integration Merger-related employee benefits 47 7 40 Professional fees 45 10 35 Facility closure costs 40 10 30 Other merger and integration-related 53 9 44 Amortization of inventory fair value adjustment 150 45 105 $ 2,908 $ 432 $ 2,476 There were no charges or credits recorded during the first quarter of 2016.

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. Schlumberger issued approximately 138 million shares of its common stock, which were valued at $9.9 billion at the time of closing, and paid cash of $2.8 billion. Prior to being acquired by Schlumberger, Cameron reported revenue of approximately $1.6 billion during the first quarter of 2016. Supplemental Pro Forma Financial Information 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 intangible asset amortization expense, interest and income taxes resulting from purchasing accounting. The pro forma amounts also reflect adjustments to the 2016 results to exclude the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value and other merger and integration costs of $254 million, net of taxes, for the three and six months ended June 30, 2016. 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. (Stated in millions, except per share amounts) 2016 Second Quarter Six Months Revenue $ 7,164 $ 15,312 Net loss attributable to Schlumberger $ (1,905 ) $ (1,290 ) Diluted loss per share $ (1.37 ) $ (0.93 )

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 June 30, 2017, Schlumberger had fixed rate debt of $13.9 billion and variable rate debt of $4.9 billion after taking into account the effect of the swap. Short-term investments and , totaled $4.3 billion at June 30, 2017. 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 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 June 30, 2017, Schlumberger recognized a cumulative net loss of $0.1 million 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 (Loss) At June 30, 2017, contracts were outstanding for the US dollar equivalent of $4.8 billion in various foreign currencies, of which $0.8 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 Jun. 30, Dec. 31, 2017 2016 Derivative Assets Derivatives designated as hedges: Foreign exchange contracts $ 5 $ 1 Other current assets Derivatives not designated as hedges: Foreign exchange contracts $ 18 $ 42 Other current assets $ 23 $ 43 Derivative Liabilities Derivatives designated as hedges: Foreign exchange contracts $ 3 $ 18 Accounts payable and accrued liabilities Cross currency swap 28 49 Other Liabilities $ 31 $ 67 Derivatives not designated as hedges: Foreign exchange contracts $ 28 $ 59 Accounts payable and accrued liabilities $ 59 $ 126 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	11. Contingencies Schlumberger is 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.
