Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited consolidated financial statements of Schlumberger Limited and its subsidiaries (“Schlumberger”) have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of Schlumberger management, all adjustments considered necessary for a fair statement have been included in the accompanying unaudited financial statements. All intercompany transactions and balances have been eliminated in consolidation. Operating results for the six -month period ended June 30 , 2015 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2015. The December 31, 2014 balance sheet information has been derived from the Schlumberger 2014 audited financial statements. For further information, refer to the Consolidated Financial Statements and notes thereto included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission on January 29, 2015. Certain prior period items have been reclassified to conform to the current period presentation. New Accounting Pronouncement In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers . This ASU amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services. Schlumberger is required to adopt this ASU no later than January 1, 201 8 with early adoption permitted on January 1, 2017. Schlumberger does not expect this ASU to have a material impact on its consolidated financial statements .

Restructuring And Related Activities [Abstract]
Charges and Credits	2. Charges and Credits Schlumberger recorded the following charges and credits in continuing operations during the first quarter of 201 5 : 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 during the first quarter associated with this headcount reduction as well as an incentivized leave of absence program. During 2014, Venezuela enacted certain changes to its foreign exchange system such that, in addition to the official rate of 6.3 Venezuelan Bolivares per US dollar, there were two other legal exchange rates that could be obtained via different exchange rate mechanisms. These changes included the expansion of the SICAD I auction rate and the introduction of what was known as the SICAD II auction process. The SICAD I and SICAD II exchange rates were approximately 11 and 50 Venezuelan Bolivares to the US dollar, respectively, at December 31, 2014. Although the functional currency of Schlumberger’s operations in Venezuela is the US dollar, a portion of the transactions in Venezuela are denominated in local currency. Prior to December 31, 2014 , Schlumberger ha d 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 this 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 February 2015, the Venezuelan government replaced SICAD II with a new foreign exchange market system known as SIMADI. The SIMAD I exchange rate was approximately 192 Venezuela Bolivares 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 . These changes result 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 . For example, if Schlumberger had applied an exchange rate of 192 Venezuelan Bolivares 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: (Stated in millions) Pretax Tax Net Classification Workforce reduction ................................................................................................. $ 390 $ 56 $ 334 Restructuring & other Currency devaluation loss in Venezuela ....................................................................................... 49 - 49 Restructuring & other $ 439 $ 56 $ 383 There were no charges or credits recorded during the second quarter of 2015 or the first six months of 2014.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	1 0 . 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 u tilizes 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 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 in income to largely offset the respective gains and losses recognized on changes in the fair value of the hedged debt. At June 30 , 2015, Schlumberger had fixed rate debt aggregating $ 8.9 billion and variable rate debt aggregating $ 4.4 billion, after taking into account the effect of the swap. Short-term investments and Fixed income investments , held to maturity , totaled $ 4.2 billion at June 30 , 2015. 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 more than 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 denom inated in local currency. Schlumberger is also exposed to risks on future cash flows relating to certain of its fixed rate debt which 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 po rtion 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 and in Accumu lated other comprehensive loss . Amounts recorded in Accumulated o ther c omprehensive l oss are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded directly to earnings. At June 30 , 2015, Schlumberger recognized a cumulative net $ 66 million loss in Accumulated other comprehensive loss relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next 12 months. Schlumberger is exposed to changes in the fair value of assets and liabilities which 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 , and changes in the fair value are recognized in the Consolidated Statement of Income as are changes in fair value of the hedged item. At June 30 , 2015, contracts were outstanding for the US dollar equivalent of $ 6.0 billion in various foreign currencies, of which $ 2.5 billion relate 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, 2015 2014 Derivative Assets Derivatives designated as hedges: Foreign exchange contracts ...................................................................................... $ 5 $ 3 Other current assets Foreign exchange contracts ............................................................................ 9 32 Other Assets $ 14 $ 35 Derivatives not designated as hedges: Foreign exchange contracts ...................................................................................... $ 22 $ 5 Other current assets $ 36 $ 40 Derivative Liabilities Derivatives designated as hedges: Foreign exchange contracts ...................................................................................... $ 58 $ 80 Accounts payable and accrued liabilities Foreign exchange contracts ............................................................................ 63 105 Other Liabilities Cross currency swap ............................................................................ 20 42 Other Liabilities $ 141 $ 227 Derivatives not designated as hedges: Foreign exchange contracts ...................................................................................... $ 4 $ 28 Accounts payable and accrued liabilities $ 145 $ 255 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	12. Contingencies During 2015 , Schlumberger resolved a previously disclosed investigation by the U.S. Department of Justice into past violations of US sanctions regarding its historical operations in Iran and Sudan that o ccurred between 2004 and 2010. 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 a total amount of approximately $233 million in fines, penalties and assessments during the second quarter of 2015, which ha d been previously accrued . This payment is reflected within Cash flow s used in discontinued operations – operating activities in Schlumberger’s Consolid ated Statement of Cash Flows . Schlumberger and its subsidiaries are party to various other 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 these other legal proceedings is remote. However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.
