Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	8. 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 2017, a Canadian-dollar functional currency subsidiary of Schlumberger issued $1.1 billion of US-dollar denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of $1.1 billion in order to hedge changes in the fair value of its $0.5 billion 2.20% Senior Notes due 2020 and its $0.6 billion 2.65% Senior Notes due 2022. These cross-currency swaps effectively convert the US-dollar notes to Canadian-dollar denominated debt with fixed annual interest rates of 1.97% and 2.52%, respectively. These cross-currency swaps are designated as cash flow hedges. The changes in the fair values of the hedges are recorded on the Consolidated Balance Sheet Accumulated Other Comprehensive Loss. Accumulated Other Comprehensive Loss At March 31, 2019, Schlumberger had fixed rate debt aggregating $13.5 billion and variable rate debt aggregating $3.0 billion, after taking into account the effect of interest rate swaps. Foreign Currency Exchange Rate Risk As a multinational company, Schlumberger generates revenue in more than 120 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 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 changes in the fair value of the hedge recorded on the Consolidated Balance Sheet Accumulated Other Comprehensive Loss. Accumulated Other Comprehensive Loss At March 31, 2019, 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 March 31, 2019, contracts were outstanding for the US dollar equivalent of $4.0 billion in various foreign currencies, of which $1.1 billion relates to hedges of debt denominated in currencies other than the functional currency.

Commitments And Contingencies Disclosure [Abstract]
Contingencies	9. 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.
