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, the 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 for certain long-term construction-type contracts over time; recoverability of fixed assets, goodwill, intangible assets, Asset Performance Solutions 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 upon the transfer of control of promised products or services to customers at an amount that reflects the consideration it expects to receive in exchange for these products or services. The vast majority of Schlumberger’s services and product offerings are short-term in nature. The time between invoicing and when payment is due under these arrangements is generally between 30 to 60 days. Revenue is occasionally generated from contractual arrangements that include multiple performance obligations. Revenue from these arrangements is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using expected costs plus margin. Revenue is recognized for certain long-term construction-type contracts over time. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Revenue is recognized as work progresses on each contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs. The estimate of total project costs has a significant impact on both the amount of revenue recognized as well as the related profit on a project. Revenue and profits on contracts can also be significantly affected by change orders and claims. Due to the nature of these projects, adjustments to estimates of contract revenue and total contract costs may be required as work progresses. Progress billings are generally issued upon completion of certain phases of work as stipulated in the contract. Any expected losses on a project are recorded in full in the period in which they become probable. Due to the nature of its businesses, Schlumberger does not have significant backlog. Total backlog was $2.8 billion at December 31, 2021, of which approximately 50% is expected to be recognized as revenue during 2022. Short-term Investments Short-term investments are comprised primarily of money market funds, time deposits, certificates of deposit, commercial paper, bonds and notes, substantially all of which are denominated in US dollars and are stated at cost plus accrued interest, which approximates fair value. For purposes of the Consolidated Statement of Cash Flows Short-term investments 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 & other income Interest & other income 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 services 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. Asset Performance Solutions Asset Performance Solutions (“APS”) projects are generally focused on developing and co-managing production of customers’ assets under long-term agreements. Schlumberger invests its own services and products into the field development activities and operations and is compensated on a fee-per-barrel basis or based on cash flow generated. This includes certain arrangements whereby Schlumberger is only compensated based on incremental production that it helps deliver above a mutually agreed baseline. Schlumberger capitalizes its investments in a project including the direct costs associated with providing its services or products. These capitalized investments are amortized to the Consolidated Statement of Income (Loss) Concentration of Credit Risk Schlumberger’s assets that are exposed to concentrations of credit risk consist primarily of cash, short-term investments, receivables from clients and derivative financial instruments. Schlumberger places its cash and short-term investments 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 generates revenue in more than 120 countries and as such, its accounts receivable are spread over many countries and customers. The United States represented 12% of Schlumberger’s net accounts receivable balance at December 31, 2021. No other country accounted for greater than 10% of Schlumberger’s accounts receivable balance. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectability and performs ongoing credit evaluations of its customers’ financial condition. If the financial condition of Schlumberger’s 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 (loss) per share of Schlumberger for each of the last three years: (Stated in millions, except per share amounts) Net Income (Loss) Attributable to Schlumberger Average Shares Outstanding Earnings (Loss) per Share 2021: Basic $ 1,881 1,400 $ 1.34 Assumed exercise of stock options - - Unvested restricted stock - 27 Diluted $ 1,881 1,427 $ 1.32 2020: Basic $ (10,518 ) 1,390 $ (7.57 ) Assumed exercise of stock options - - Unvested restricted stock - - Diluted $ (10,518 ) 1,390 $ (7.57 ) 2019: Basic $ (10,137 ) 1,385 $ (7.32 ) Assumed exercise of stock options - - Unvested restricted stock - - Diluted $ (10,137 ) 1,385 $ (7.32 ) The number of outstanding employee stock options to purchase shares of Schlumberger common stock and unvested restricted stock units that were not included in the computation of diluted earnings/loss per share, because to do so would have had an anti-dilutive effect, were as follows: (Stated in millions) 2021 2020 2019 Employee stock options 42 48 46 Unvested restricted stock - 19 12

Charges and Credits 2021 Schlumberger recorded the following charges and credits during 2021: (Stated in millions) Pretax Tax Net Third quarter: Unrealized gain on marketable securities $ (47 ) $ (11 ) $ (36 ) Fourth quarter: Gain on sale of Liberty shares (28 ) (4 ) (24 ) Early repayment of bonds 10 - 10 $ (65 ) $ (15 ) $ (50 ) Third quarter 2021: • During the third quarter of 2021, a start-up company that Schlumberger previously invested in was acquired. As a result of this transaction, Schlumberger’s ownership interest was converted into shares of a publicly traded company. Schlumberger recognized an unrealized pretax gain of $47 million to increase the carrying value of this investment to its estimated fair value of approximately $ 55 million. This unrealized gain is reflected in Interest & other income in the Consolidated Statement of Income (Loss) . Fourth quarter 2021: • On December 31, 2020, Schlumberger contributed its onshore hydraulic fracturing business in the United States and Canada (“OneStim”), including its pressure pumping, pumpdown perforating and Permian frac sand business to Liberty Oilfield Services Inc. (“Liberty”) in exchange for a 37% equity interest in Liberty. During the fourth quarter of 2021, Schlumberger sold 9.5 million of its shares of Liberty and received proceeds of $109 million. As a result of this transaction Schlumberger recognized a gain of $28 million. This gain is classified in Interest & other income in the Consolidated Statement of Income (Loss) . As of December 31, 2021, Schlumberger had a 31% equity interest in Liberty. Based on the quoted market prices of Liberty’s shares, the fair value of Schlumberger’s investment in Liberty was approximately $550 • On November 30, 2021, Schlumberger deposited sufficient funds with the trustee for its $1.0 billion of 2.40% Senior Notes due 2022 (including payment of the February 1, 2022 interest payment) to satisfy and discharge all of its obligations relating to such notes. As a result of this transaction, Schlumberger recorded a charge of $10 million. This charge is reflected in Interest in the Consolidated Statement of Income (Loss) . 2020 Schlumberger recorded the following charges and credits during 2020, all of which, unless otherwise noted, are classified in Impairments & other Consolidated Statement of Income (Loss) (Stated in millions) Pretax Tax Net First quarter: Goodwill $ 3,070 $ - $ 3,070 Intangible assets impairments 3,321 815 2,506 Asset Performance Solutions investments 1,264 (4 ) 1,268 North America pressure pumping impairment 587 133 454 Workforce reductions 202 7 195 Other 79 9 70 Valuation allowance - (164 ) 164 Second quarter: Workforce reductions 1,021 71 950 Asset Performance Solutions investments 730 15 715 Fixed asset impairments 666 52 614 Inventory write-downs 603 49 554 Right-of-use asset impairments 311 67 244 Costs associated with exiting certain activities 205 (25 ) 230 Multiclient seismic data impairment 156 2 154 Repurchase of bonds 40 2 38 Postretirement benefits curtailment gain (69 ) (16 ) (53 ) Other 60 4 56 Third quarter: Facility exit charges 254 39 215 Workforce reductions 63 - 63 Other 33 1 32 Fourth quarter: Gain on sale of OneStim (104 ) (11 ) (93 ) Unrealized gain on marketable securities (39 ) (9 ) (30 ) Other 62 4 58 $ 12,515 $ 1,041 $ 11,474 First quarter 2020: • Geopolitical events that increased the supply of low-priced oil to the global market occurred at the same time that demand weakened due to the worldwide effects of the COVID-19 pandemic, leading to a collapse in oil prices during March 2020. As a result, Schlumberger’s market capitalization deteriorated significantly compared to the end of 2019. Schlumberger’s stock price reached a low during the first quarter of 2020 not seen since 1995. Additionally, the Philadelphia Oil Services Sector index (“OSX”), which is comprised of companies involved in the oil services sector, reached an all-time low. As a result of these facts, Schlumberger determined that it was more likely than not that the fair value of certain of its reporting units was less than their carrying value. Therefore, Schlumberger performed an interim goodwill impairment test. Schlumberger had 11 reporting units with goodwill balances aggregating $16.0 billion. Schlumberger determined that the fair value of four of its reporting units, representing $4.5 billion of goodwill, was substantially in excess of their carrying value. Schlumberger performed a detailed quantitative impairment assessment of the remaining seven reporting units, which represented $11.5 billion of goodwill. As a result of this assessment, Schlumberger concluded that the goodwill associated with each of these seven reporting units was impaired, resulting in a $3.1 billion goodwill impairment charge. Following the $3.1 billion goodwill impairment charge relating to these seven reporting units, six of these reporting units had a remaining goodwill balance. These goodwill balances ranged between $0.2 billion and $5.0 billion and aggregated to $8.4 billion as of March 31, 2020. Schlumberger used the income approach to estimate the fair value of its reporting units, but also considered the market approach to validate the results. The income approach estimates the fair value by discounting each reporting unit’s estimated future cash flows using Schlumberger’s estimate of the discount rate, or expected return, that a marketplace participant would have required as of the valuation date. The market approach includes the use of comparative multiples to corroborate the discounted cash flow results. The market approach involves significant judgement involved in the selection of the appropriate peer group companies and valuation multiples. Some of the more significant assumptions inherent in the income approach include the estimated future net annual cash flows for each reporting unit and the discount rate. Schlumberger selected the assumptions used in the discounted cash flow projections using historical data supplemented by current and anticipated market conditions and estimated growth rates. Schlumberger’s estimates are based upon assumptions believed to be reasonable. However, given the inherent uncertainty in determining the assumptions underlying a discounted cash flow analysis, particularly in a volatile market, actual results may differ from those used in Schlumberger’s valuations which could result in additional impairment charges in the future. The discount rates utilized to value Schlumberger’s reporting units were between 12.0% and 13.5%, depending on the risks and uncertainty inherent in the respective reporting unit as well as the size of the reporting unit. Assuming all other assumptions and inputs used in each of the respective discounted cash flow analysis were held constant, a 50-basis point increase or decrease in the discount rate assumptions would have changed the fair value of the seven reporting units, on average, by less than 5%. • The negative market indicators described above were triggering events that indicated that certain of Schlumberger’s long-lived intangible and tangible assets may have been impaired. Recoverability testing indicated that certain long-lived assets were impaired. The estimated fair value of these assets was determined to be below their carrying value. As a result, Schlumberger recorded the following impairment charges: - $3.3 billion relating to intangible assets, of which $2.2 billion relates to Schlumberger’s 2016 acquisition of Cameron International Corporation and $1.1 billion relates to Schlumberger’s 2010 acquisition of Smith International, Inc. Following this impairment charge, the carrying value of the impaired intangible assets was approximately $0.9 billion. - $1.3 billion relating to the carrying value of certain APS projects in North America. - $0.6 billion of fixed assets associated with the pressure pumping business in North America. • $202 million of severance. • $79 million of other restructuring charges, primarily consisting of the impairment of an equity method investment that was determined to be other-than-temporarily impaired. • $164 million relating to a valuation allowance against certain deferred tax assets. Second quarter 2020: • As previously noted, late in the first quarter of 2020 geopolitical events that increased the supply of low-priced oil to the global market occurred at the same time as demand weakened due to the worldwide effects of the COVID-19 pandemic, which led to a collapse in oil prices. As a result, the second quarter of 2020 was the most challenging quarter in decades. Schlumberger responded to these market conditions by taking actions to restructure its business and rationalize its asset base during the second quarter of 2020. These actions included reducing headcount, closing facilities and exiting business lines in certain countries. Additionally, due to the resulting activity decline, Schlumberger had assets that would no longer be utilized. As a consequence of these circumstances and decisions, Schlumberger recorded the following restructuring and asset impairment charges: - $1.021 billion of severance associated with reducing its workforce by more than 21,000 employees. - $730 million relating to the carrying value of certain APS projects in Latin America. - $666 million of fixed asset impairments primarily relating to equipment that would no longer be utilized and facilities it exited. - $603 million write-down of the carrying value of inventory to its net realizable value. - $311 million write-down of right-of-use assets under operating leases associated with leased facilities Schlumberger exited and excess equipment. - $205 million of costs associated with exiting certain activities. - $156 million impairment of certain multiclient seismic data. - $60 million of other costs, including a $42 million increase in the allowance for the doubtful accounts. • Schlumberger repurchased all $600 million of its 4.20% Senior Notes due 2021 and $935 million of its 3.30% Senior Notes due 2021. Schlumberger paid a premium of $40 million in connection with these repurchases. • As a consequence of the workforce reductions described above, Schlumberger recorded a curtailment gain of $69 million relating to its US postretirement medical plan. See Note 16 – Pension and Other Postretirement Benefit Plans for further details. Third quarter 2020: • Schlumberger recorded the following restructuring charges: - $254 million of facility exit charges as Schlumberger continued to rationalize its real estate footprint relating to both leased and owned facilities. - $63 million of severance. - $33 million of other charges. Fourth quarter 2020: • On December 31, 2020, Schlumberger contributed its OneStim business to Liberty in exchange for a 37% equity interest in Liberty. As a result of this transaction, Schlumberger recognized a gain of $104 million. This gain is classified in Gains on sales of businesses in the Consolidated Statement of Income (Loss) . • During the fourth quarter of 2020, a start-up company that Schlumberger previously invested in completed an initial public offering. As a result, Schlumberger recognized an unrealized gain of $39 million to increase the carrying value of this investment to its fair value of approximately $43 million. This unrealized gain is reflected in Interest & other income in the Consolidated Statement of Income (Loss) . Schlumberger sold its interest in this company during 2021. • During the fourth quarter of 2020, Schlumberger entered into an agreement to purchase new software licenses. This transaction rendered certain previously purchased licenses obsolete. As a result, Schlumberger wrote off the remaining $62 million of net book value associated with the obsolete software licenses. 2019 Schlumberger recorded the following charges and credits during 2019, all of which are classified as Impairments & other Consolidated Statement of Income (Loss) (Stated in millions) Pretax Tax Net Third quarter: Goodwill impairment $ 8,828 $ 43 $ 8,785 Intangible assets impairment 1,085 248 837 North America pressure pumping 1,575 344 1,231 Other North America-related 310 53 257 Argentina 127 - 127 Equity-method investments 231 12 219 Asset Performance Solutions investments 294 - 294 Other 242 13 229 Fourth quarter: North America restructuring 225 51 174 Other restructuring 104 (33 ) 137 Workforce reductions 68 8 60 Pension settlement accounting 37 8 29 Repurchase of bonds 22 5 17 Gain on formation of Sensia joint venture (247 ) (42 ) (205 ) $ 12,901 $ 710 $ 12,191 Third quarter of 2019: • During August 2019, Schlumberger’s market capitalization deteriorated significantly compared to the end of the second quarter of 2019. Schlumberger’s stock price reached a low not seen since 2005. Additionally, the OSX reached an 18-year low. As a result of these facts, Schlumberger determined that it was more likely than not that the fair value of certain of its reporting units was less than their carrying value. Therefore, Schlumberger performed an interim goodwill impairment test as of August 31, 2019. As of August 31, 2019, Schlumberger had 17 reporting units with goodwill balances aggregating $25.0 billion. Schlumberger determined that the fair value of seven of its reporting units, representing approximately $13.8 billion of the goodwill, was substantially in excess of their carrying value. Schlumberger performed a detailed quantitative impairment assessment of the remaining 10 reporting units, which represented $11.2 billion of goodwill. As a result of this assessment, Schlumberger concluded that the goodwill associated with nine of the 10 reporting units was impaired, resulting in an $8.8 billion goodwill impairment charge. Schlumberger primarily used the income approach to estimate the fair value of its reporting units, but also considered the market approach to validate the results. The income approach estimates the fair value by discounting each reporting unit’s estimated future cash flows using Schlumberger’s estimate of the discount rate, or expected return, that a marketplace participant would have required as of the valuation date. The market approach includes the use of comparative multiples to corroborate the discounted cash flow results. The market approach involves significant judgement involved in the selection of the appropriate peer group companies and valuation multiples. Some of the more significant assumptions inherent in the income approach include the estimated future net annual cash flows for each reporting unit and the discount rate. Schlumberger selected the assumptions used in the discounted cash flow projections using historical data supplemented by current and anticipated market conditions and estimated growth rates. Schlumberger’s estimates are based upon assumptions believed to be reasonable. The discount rates utilized to value Schlumberger’s reporting units were between 12.5% and 14.0%, depending on the risks and uncertainty inherent in the respective reporting unit. Assuming all other assumptions and inputs used in each of the respective discounted cash flow analysis were held constant, a 50 basis point increase in the discount rate assumption would have increased the goodwill impairment charge by approximately $0.3 billion. Conversely, assuming all other assumptions and inputs used in each of the respective discounted cash flow analysis were held constant, a 50 basis point decrease in the discount rate assumption would have decreased the goodwill impairment charge by approximately $0.4 billion. • The negative market indicators described above combined with deteriorating market conditions in North America, as well as the results of the previously mentioned fair value determinations of certain of Schlumberger’s reporting units and the appointment of a new Chief Executive Officer, were all triggering events that indicated that certain of Schlumberger’s long-lived tangible and intangible assets may be impaired. Recoverability testing, which was performed as of August 31, 2019, indicated that long-lived assets associated with certain asset groups were impaired. The estimated fair value of these asset groups was determined to be below their carrying value. As a result, Schlumberger recorded the following impairment and related charges: - $1.085 billion of intangible assets, of which $842 million relates to Schlumberger’s 2010 acquisition of Smith International, Inc. The remaining $243 million primarily relates to other acquisitions in North America. - $1.575 billion of charges relating to Schlumberger’s pressure pumping business in North America. This amount consists of $1.324 billion of pressure pumping equipment and related assets; $98 million of right-of-use assets under operating leases; $121 million relating to a supply contract; $19 million of inventory; and $13 million of severance. - $310 million of charges primarily relating to other businesses in North America, consisting of $230 million of fixed asset impairments, $70 million of inventory write-downs and $10 million of severance. • As a result of the economic challenges in Argentina, Schlumberger recorded $127 million of charges consisting of $72 million of asset impairments, a $26 million devaluation charge and $29 million of severance. • Schlumberger recorded the following impairment and restructuring charges: - $231 million relating to certain equity method investments that were determined to be other-than-temporarily impaired. - $ 294 million impairment relating to the carrying value of certain smaller APS projects. - $242 million of restructuring charges consisting of: $62 million of severance; $57 million relating to the acceleration of stock-based compensation expense associated with certain individuals; $49 million of business divestiture costs; $29 million relating to the repurchase of certain Senior Notes; and $45 million of other provisions. Fourth quarter of 2019: • Schlumberger recorded the following restructuring charges: - $225 million associated with facility closures and costs to exit certain activities in North America. These charges included $123 million relating to fixed assets; $55 million of right-of-use assets under operating leases; and $47 million of other exit costs. - $104 million primarily relating to restructuring certain activities outside of North America, which included $68 million associated with assets to be divested and $36 million of facility closure costs. - $68 million of severance associated with streamlining its operations and exiting certain activities. • Certain of Schlumberger’s defined benefit pension plans offered former Schlumberger employees, who had not yet commenced receiving their pension benefits, an opportunity to receive a lump sum payout of their vested pension benefit which resulted in Schlumberger recording a pension settlement charge of $37 million. See Note 16 – Pension and Other Postretirement Benefit Plans for further details. • Schlumberger repurchased the remaining $416 million of its 3.00% Senior Notes due 2020; $126 million of its 4.50% Senior Notes due 2021; $500 million of its 4.20% Senior Notes due 2021; and $106 million of its 3.60% Senior Notes due 2022. These transactions resulted in a $22 million charge. • On October 1, 2019, Schlumberger and Rockwell completed the formation of Sensia, a joint venture that is the oil and gas industry’s first digitally enabled integrated automation solutions provider. Rockwell Automation owns 53% of the joint venture and Schlumberger owns 47%. In connection with this transaction, Schlumberger received a cash payment of $238 million. Schlumberger will account for its investment under the equity method of accounting. Schlumberger recorded a $247 million gain as a result of the deconsolidation of certain of its businesses in connection with the formation of the joint venture. This gain, which is equal to the sum of the $238 million of cash proceeds received and the fair value of Schlumberger’s retained noncontrolling investment in the businesses it contributed less the carrying amount of the assets and liabilities of such businesses at the time of the closing, is classified as Gains on sale of businesses in the Consolidated Statement of Income (Loss) . The fair value of certain of the assets impaired during 2020 and 2019 was estimated based on the present value of projected future cash flows that the underlying assets are expected to generate. Such estimates included unobservable inputs that required significant judgment.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	9. Derivative Instruments and Hedging Activities As a multinational company, Schlumberger conducts its business in over 120 countries. Schlumberger’s functional currency is primarily the US dollar. Approximately 70% of Schlumberger’s revenues in 2021 were 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 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 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 cross-currency swaps to provide a hedge against these cash flow risks. Included in Other Assets Other Liabilities During 2019, a US-dollar functional currency subsidiary of Schlumberger issued €1.5 billion of Euro-denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of €1.5 billion in order to hedge changes in the fair value of its €0.5 billion 0.00% Notes due 2024, €0.5 billion 0.25% Notes due 2027 and €0.5 billion 0.50% Notes due 2031. These cross-currency swaps effectively convert the Euro-denominated notes to US-dollar denominated debt with fixed annual interest rates of 2.29%, 2.51% and 2.76%, respectively. During 2020, a US-dollar functional currency subsidiary of Schlumberger issued €0.8 billion of Euro-denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of €0.8 billion in order to hedge changes in the fair value of its €0.4 billion of 0.25% Notes due 2027 and €0.4 billion of 0.50% Notes due 2031. These cross-currency swaps effectively convert the Euro-denominated notes to US-dollar denominated debt with fixed annual interest rates of 1.87% and 2.20%, respectively. During 2020, a US-dollar functional currency subsidiary of Schlumberger issued €2.0 billion of Euro-denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of €2.0 billion in order to hedge changes in the fair value of its €1.0 billion of 1.375% Guaranteed Notes due 2026 and €1.0 billion of 2.00% Guaranteed Notes due 2032. These cross-currency swaps effectively convert the swapped portion of the Euro-denominated notes to US-dollar denominated debt with fixed annual interest rates of 2.77% and 3.49%, respectively. During 2020, a Canadian dollar functional currency subsidiary of Schlumberger issued $0.5 billion of US dollar denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of $0.5 billion in order to hedge changes in the fair value of its $0.5 billion 1.40% Senior Notes due 2025. These cross-currency swaps effectively convert the US dollar notes to Canadian dollar denominated debt with a fixed annual interest rate of 1.73%. Schlumberger is exposed to changes in the fair value of assets and liabilities 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 is recorded on the Consolidated Balance Sheet Consolidated Statement of Income (Loss), Consolidated Statement of Income (Loss) During the fourth quarter of 2021, Schlumberger entered into derivative contracts that hedge the price of oil relating to approximately 75% of the projected 2022 oil production of one of its APS projects.

Restricted Stock Schlumberger grants performance share units to certain key employees. The number of shares earned is determined at the end of each performance period based on Schlumberger’s achievement of certain predefined targets as described in the underlying performance share unit agreement. In the event Schlumberger exceeds the predefined target, shares for up to a maximum of 250% of the target award may be awarded. In the event Schlumberger falls below the predefined target, a reduced number of shares may be awarded. If Schlumberger falls below the threshold award performance level, no shares will be awarded. As of December 31, 2021, 4.9 million performance share units were outstanding assuming the achievement of 100% of target. All other restricted stock awards generally vest at the end of three years or vest ratably in equal tranches over a three-year period. Restricted stock awards do not pay dividends or have voting rights prior to vesting. Accordingly, the fair value of a restricted stock award is generally 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: 2021 2020 2019 Dividend yield 2.0 % 4.0 % 5.3 % Expected volatility 67 % 43 % 30 % Risk-free interest rate 0.07 % 0.88 % 2.3 % Weighted-average fair value per share $ 6.72 $ 5.38 $ 5.81 Total Stock-based Compensation Expense The following summarizes stock-based compensation expense recognized in income: (Stated in millions) 2021 2020 2019 Stock options $ 36 $ 75 $ 99 Restricted stock 254 293 274 DSPP 34 29 32 $ 324 $ 397 $ 405 At December 31, 2021, there was $277 million of total unrecognized compensation cost related to nonvested stock-based compensation arrangements, of which $171 million is expected to be recognized in 2022, $90 million in 2023, $15 million in 2024, and $1 million in 2025. As of December 31, 2021, approximately 44 million shares of Schlumberger common stock were available for future grants under Schlumberger’s stock-based compensation programs.

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.

Contingencies	14. 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.

Pension and Other Benefit Plans	16. Pension and Other Postretirement 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 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 2021 2020 2019 2021 2020 2019 Discount rate 2.60 % 3.30 % 4.30 % 2.38 % 3.27 % 4.00 % Compensation increases 4.00 % 4.00 % 4.00 % 4.82 % 4.83 % 4.83 % Return on plan assets 6.60 % 6.60 % 6.60 % 6.73 % 6.71 % 7.22 % Net pension cost (credit) included the following components: (Stated in millions) US International 2021 2020 2019 2021 2020 2019 Service cost $ 44 $ 55 $ 49 $ 117 $ 140 $ 112 Interest cost 127 148 180 267 301 333 Expected return on plan assets (254 ) (233 ) (232 ) (640 ) (591 ) (592 ) Amortization of prior service cost - 8 10 - - 7 Amortization of net loss 44 41 29 227 159 70 Settlement charge - - 37 - - - $ (39 ) $ 19 $ 73 $ (29 ) $ 9 $ (70 ) During 2019, certain of Schlumberger’s deferred benefit pension plans offered former Schlumberger employees, who had not yet commenced receiving their pension benefits, an opportunity to receive a lump sum payout of their vested pension benefit. Schlumberger’s pension plans paid $257 million from pension plan assets to those who accepted this offer, thereby reducing its pension benefit obligations. These transactions resulted in a non-cash pension settlement charge of $37 million, representing the immediate recognition of the related deferred actuarial losses in Accumulated Other Comprehensive Loss Charges and Credits 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 2021 2020 2021 2020 Discount rate 3.00 % 2.60 % 2.83 % 2.38 % Compensation increases 4.00 % 4.00 % 4.83 % 4.82 % The changes in the projected benefit obligation, plan assets and funded status of the plans were as follows: (Stated in millions) US International 2021 2020 2021 2020 Change in Projected Benefit Obligations Projected benefit obligation at beginning of year $ 4,940 $ 4,593 $ 11,140 $ 9,647 Service cost 44 55 117 140 Interest cost 127 148 267 301 Contribution by plan participants - - 53 94 Actuarial (gains) losses (211 ) 370 (586 ) 1,228 Currency effect - - (18 ) 68 Benefits paid (232 ) (226 ) (355 ) (338 ) Projected benefit obligation at end of year $ 4,668 $ 4,940 $ 10,618 $ 11,140 Change in Plan Assets Plan assets at fair value at beginning of year $ 4,776 $ 4,236 $ 10,493 $ 9,363 Actual return on plan assets 145 760 1,040 1,282 Currency effect - - (28 ) 72 Company contributions 7 6 18 20 Contributions by plan participants - - 53 94 Benefits paid (232 ) (226 ) (355 ) (338 ) Plan assets at fair value at end of year $ 4,696 $ 4,776 $ 11,221 $ 10,493 Asset / (Unfunded Liability) $ 28 $ (164 ) $ 603 $ (647 ) Amounts Recognized in Balance Sheet Postretirement Benefits $ (212 ) $ (199 ) $ (19 ) $ (849 ) Other Assets 240 35 622 202 $ 28 $ (164 ) $ 603 $ (647 ) Amounts Recognized in Accumulated Other Comprehensive Loss Actuarial losses $ 276 $ 423 $ 1,174 $ 1,981 Prior service cost - 1 - - $ 276 $ 424 $ 1,174 $ 1,981 Accumulated benefit obligation $ 4,484 $ 4,739 $ 10,370 $ 10,844 The asset / (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 (“ABO”) represents the actuarial present value of benefits based on employee service and compensation but does not include an assumption about future compensation levels. Actuarial gains arising during 2021 and actuarial losses arising during 2020 were primarily attributable to changes in the discount rate used to determine the PBO. The weighted-average allocation of plan assets and the target allocations by asset category as of December 31, 2021 are as follows: US International Target 2021 2020 Target 2021 2020 Equity securities 4 - 8 % 5 % 15 % 20 - 30 % 23 % 45 % Debt securities 80 - 90 84 76 50 - 60 53 35 Cash and cash equivalents 0 - 3 2 3 0 - 5 3 3 Alternative investments 8 - 15 9 6 19 - 26 21 17 100 % 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 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, 2021 and 2020, 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.

Schlumberger does not expect to make any material contributions Postretirement Benefits Other Than Pensions Schlumberger provides healthcare benefits to certain former US employees who have retired. 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 2021 2020 2021 2020 2019 Discount rate 3.00 % 2.60 % 2.60 % 3.30 % 4.30 % Return on plan assets - - 7.00 % 7.00 % 7.00 % Current medical cost trend rate 6.75 % 7.25 % 7.00 % 7.25 % 7.50 % Ultimate medical cost trend rate 4.50 % 4.50 % 4.50 % 4.50 % 4.50 % Year that the rate reaches the ultimate trend rate 2031 2031 2031 2031 2031 The net periodic benefit credit for the US postretirement medical plan included the following components: (Stated in millions) 2021 2020 2019 Service cost $ 28 $ 31 $ 29 Interest cost 32 36 45 Expected return on plan assets (73 ) (70 ) (64 ) Amortization of prior service credit (23 ) (25 ) (28 ) Curtailment gain - (69 ) - $ (36 ) $ (97 ) $ (18 ) Due to the actions taken by Schlumberger to reduce its global workforce during 2020, Schlumberger experienced a significant reduction in the expected aggregate years of future service of its employees in its US postretirement medical plan. Accordingly, Schlumberger recorded a curtailment gain of $69 million during the second quarter of 2020 relating to this plan. The curtailment gain includes recognition of the decrease in the benefit obligation as well as a portion of the previously unrecognized prior service credit, reflecting the reduction in expected years of future service. As a result of the curtailment, Schlumberger performed a remeasurement of the plan, which had an immaterial impact. This gain was classified in Impairments & other Consolidated Statement of Income (Loss) Charges and Credits The changes in the accumulated postretirement benefit obligation, plan assets and funded status were as follows: (Stated in millions) 2021 2020 Change in Projected Benefit Obligations Benefit obligation at beginning of year $ 1,234 $ 1,193 Service cost 28 31 Interest cost 32 36 Contribution by plan participants 10 8 Actuarial (gains) losses (95 ) 64 Benefits paid (63 ) (58 ) Curtailment - (40 ) Benefit obligation at end of year $ 1,146 $ 1,234 Change in Plan Assets Plan assets at fair value at beginning of year $ 1,356 $ 1,185 Actual return on plan assets 15 221 Contributions by plan participants 10 8 Benefits paid (63 ) (58 ) Plan assets at fair value at end of year $ 1,318 $ 1,356 Asset $ 172 $ 122 Amounts Recognized in Accumulated Other Comprehensive Loss Actuarial gains $ 225 $ 186 Prior service credit 81 104 $ 306 $ 290 The asset balance relating to this plan was included in Other Assets Consolidated Balance Sheet The assets of the US postretirement medical plan are invested 13% in equity securities and 87% in debt securities at December 31, 2021.

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, the 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 for certain long-term construction-type contracts over time; recoverability of fixed assets, goodwill, intangible assets, Asset Performance Solutions 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 upon the transfer of control of promised products or services to customers at an amount that reflects the consideration it expects to receive in exchange for these products or services. The vast majority of Schlumberger’s services and product offerings are short-term in nature. The time between invoicing and when payment is due under these arrangements is generally between 30 to 60 days. Revenue is occasionally generated from contractual arrangements that include multiple performance obligations. Revenue from these arrangements is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using expected costs plus margin. Revenue is recognized for certain long-term construction-type contracts over time. These contracts involve significant design and engineering efforts in order to satisfy custom designs for customer-specific applications. Revenue is recognized as work progresses on each contract. Progress is measured by the ratio of actual costs incurred to date on the project in relation to total estimated project costs. The estimate of total project costs has a significant impact on both the amount of revenue recognized as well as the related profit on a project. Revenue and profits on contracts can also be significantly affected by change orders and claims. Due to the nature of these projects, adjustments to estimates of contract revenue and total contract costs may be required as work progresses. Progress billings are generally issued upon completion of certain phases of work as stipulated in the contract. Any expected losses on a project are recorded in full in the period in which they become probable. Due to the nature of its businesses, Schlumberger does not have significant backlog. Total backlog was $2.8 billion at December 31, 2021, of which approximately 50% is expected to be recognized as revenue during 2022.
Short-term and Investments	Short-term Investments Short-term investments are comprised primarily of money market funds, time deposits, certificates of deposit, commercial paper, bonds and notes, substantially all of which are denominated in US dollars and are stated at cost plus accrued interest, which approximates fair value. For purposes of the Consolidated Statement of Cash Flows Short-term investments
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 & other income Interest & other income
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 services 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.
Asset Performance Solutions	Asset Performance Solutions Asset Performance Solutions (“APS”) projects are generally focused on developing and co-managing production of customers’ assets under long-term agreements. Schlumberger invests its own services and products into the field development activities and operations and is compensated on a fee-per-barrel basis or based on cash flow generated. This includes certain arrangements whereby Schlumberger is only compensated based on incremental production that it helps deliver above a mutually agreed baseline. Schlumberger capitalizes its investments in a project including the direct costs associated with providing its services or products. These capitalized investments are amortized to the Consolidated Statement of Income (Loss)
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, receivables from clients and derivative financial instruments. Schlumberger places its cash and short-term investments 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 generates revenue in more than 120 countries and as such, its accounts receivable are spread over many countries and customers. The United States represented 12% of Schlumberger’s net accounts receivable balance at December 31, 2021. No other country accounted for greater than 10% of Schlumberger’s accounts receivable balance. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectability and performs ongoing credit evaluations of its customers’ financial condition. If the financial condition of Schlumberger’s customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.
