Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying unaudited consolidated financial statements of NOV Inc. (“NOV” or the “Company”) present information in accordance with GAAP in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X. They do not include all information or footnotes required by GAAP in the United States for complete consolidated financial statements and should be read in conjunction with the Company’s 2020 Annual Report on Form 10-K. In our opinion, the consolidated financial statements include all adjustments, which are of a normal recurring nature unless otherwise disclosed, necessary for a fair presentation of the results for the interim periods. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year. The fair values of cash and cash equivalents, receivables and payables were approximately the same as their presented carrying values because of the short maturities of these instruments. The fair value of long-term debt is provided in Note 8, and the fair values of derivative financial instruments are provided in Note 11.

A majority of the Company’s international entities in which there is a substantial investment have the local currency as their functional currency. As a result, currency translation adjustments resulting from the process of translating the entities’ financial statements into the reporting currency are reported in other comprehensive income (loss). For the three months ended March 31, 2021, a majority of these local currencies weakened against the U.S. dollar, resulting in other comprehensive loss of $19 million compared to other comprehensive loss of $180 million for the three months ended March 31, 2020. The effect of changes in the fair values of derivatives designated as cash flow hedges are accumulated in other comprehensive income (loss), net of tax, until the underlying transactions they hedge are realized. The movement in other comprehensive income (loss) from period to period will be the result of the combination of: 1) changes in fair value of open derivatives (-$2 million during the three months ended March 31, 2021); and, 2) the outflow of other comprehensive income (loss) related to cumulative changes in the fair value of derivatives that have settled in the current period that is reclassified into earnings in the current period ($0 during the three months ended March 31, 2021).

Contract Assets and Liabilities Contract assets include unbilled amounts when revenue recognized exceeds the amount billed to the customer under contracts where revenue is recognized over-time. Contract liabilities consist of customer billings in excess of revenue recognized under over-time contracts, customer advance payments and deferred revenue. The changes in the carrying amount of net contract assets and contract liabilities are as follows (in millions): Contract Assets Contract Liabilities Balance at December 31, 2020 $ 611 $ 354 Provision (1 ) - Billings (226 ) 204 Revenue recognized 214 (205 ) Currency translation adjustments and other (21 ) (4 ) Balance at March 31, 2021 $ 577 $ 349 Allowance for Credit Losses The Company estimates its allowance for credit losses using information about past events, current conditions and risk characteristics of each customer, and reasonable and supportable forecasts relevant to assessing risk associated with the collectability of Receivables and Contract Assets.

Leases

Leases	3 Months Ended
	Mar. 31, 2021
Leases [Abstract]
Leases	7 . The Company leases certain facilities and equipment to support its operations around the world. These leases generally require the Company to pay maintenance, insurance, taxes and other operating costs in addition to rent. Renewal options are common in longer term leases; however, it is rare that the Company is reasonably certain to exercise a renewal option at the inception of a least due to the cyclical nature of the Company’s business. Residual value guarantees are not typically part of the Company’s leases. Occasionally, the Company sub-leases excess facility space, generally at terms similar to the source lease. The Company reviews agreements at inception to determine if they include a lease and, when they do, uses its incremental borrowing rate to determine the present value of the future lease payments as implicit interest rate in most of the Company’s leases is not readily determinable. Components of leases are as follows (in millions): March 31, December 31, 2021 2020 Current portion of lease liabilities: Operating $ 81 $ 82 Financing 25 28 Total $ 106 $ 110 March 31, December 31, 2021 2020 Long-term portion of lease liability: Operating $ 361 $ 376 Financing 229 $ 236 Total $ 590 $ 612

The Company had the following outstanding foreign currency forward contracts at March 31, 2021 (in millions): Currency Denomination March 31, December 31, Foreign Currency 2021 2020 South Korean Won KRW 17,600 KRW 17,600 Norwegian Krone NOK 3,131 NOK 3,817 Russian Ruble RUB 1,159 RUB 1,118 Mexican Peso MXN 421 MXN 402 Japanese Yen JPY 390 JPY 340 U.S. Dollar USD 308 USD 367 Euro EUR 131 EUR 116 South African Rand ZAR 124 ZAR 124 Singapore Dollar SGD 31 SGD 31 British Pound Sterling GBP 17 GBP 18 Danish Krone DKK 5 DKK 875 Canadian Dollar CAD 2 CAD 1 Brazilian Real BRL - BRL 768 Cash Flow Hedging Strategy To protect against the volatility of forecasted foreign currency cash flows resulting from forecasted revenues and expenses, the Company has instituted a cash flow hedging program. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative instrument is recorded in accumulated other comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings (e.g., in “revenues” when the hedged transactions are cash flows associated with forecasted revenues). The Company includes time value in hedge relationships. The Company expects ($19) million of the accumulated other comprehensive income (loss) will be reclassified into earnings within the next twelve months. Non-designated Hedging Strategy The Company enters into forward exchange contracts to hedge certain nonfunctional currency monetary accounts. The gain or loss on the derivative instrument is recognized in other income (expense), together with the foreign exchange driven value changes in the hedged nonfunctional monetary accounts. The amount of gain (loss) recognized in other income (expense), net was ($4) million and ($43) million for the three months ended March 31, 2021 and 2020, respectively. The Company has the following fair values of its derivative instruments and their balance sheet classifications (in millions): Asset Derivatives Liability Derivatives Fair Value Fair Value Balance Sheet March 31, December 31, Balance Sheet March 31, December 31, Location 2021 2020 Location 2021 2020 Derivatives designated as hedging instruments under ASC Topic 815 Foreign exchange contracts Prepaid and other current assets $ 4 $ 17 Accrued liabilities $ 6 $ 11 Foreign exchange contracts Other Assets — 12 Other liabilities — - Total derivatives designated as hedging instruments under ASC Topic 815 $ 4 $ 29 $ 6 $ 11 Derivatives not designated as hedging instruments under ASC Topic 815 Foreign exchange contracts Prepaid and other current assets $ 20 $ 17 Accrued liabilities $ 2 $ 4 Foreign exchange contracts Other Assets 3 — Other Liabilities — — Total derivatives not designated as hedging instruments under ASC Topic 815 $ 23 $ 17 $ 2 $ 4 Total derivatives $ 27 $ 46 $ 8 $ 15

Net Loss Attributable to Company Per Share	1 2 . The following table sets forth the computation of weighted average basic and diluted shares outstanding (in millions, except per share data): Three Months Ended March 31, 2021 2020 Numerator: Net loss attributable to Company $ (115 ) $ (2,047 ) Denominator: Basic—weighted average common shares outstanding 385 383 Dilutive effect of employee stock options and other unvested stock awards — — Diluted outstanding shares 385 383 Net loss attributable to Company per share: Basic $ (0.30 ) $ (5.34 ) Diluted $ (0.30 ) $ (5.34 ) Cash dividends per share $ — $ 0.05 ASC Topic 260, “Earnings Per Share” requires companies with unvested participating securities to utilize a two-class method for the computation of net income attributable to Company per share. The two-class method requires a portion of net income attributable to Company to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, if declared. Net income (loss) attributable to Company allocated to these participating securities was immaterial for the three months ended March 31, 2021 and 2020 and therefore not excluded from net income attributable to Company per share calculation. The Company had stock options outstanding that were anti-dilutive totaling 24 million shares and 27 million shares for each of the three months ended March 31, 2021 and 2020, respectively.

Commitments and Contingencies

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	1 4 . Our business is governed by laws and regulations promulgated by U.S. federal and state governments and regulatory agencies, as well as international governmental authorities in the many countries in which we conduct business, including those related to the oilfield service industry. In the United States these governmental authorities include: the U.S. Department of Labor, the Occupational Safety and Health Administration, the Environmental Protection Agency, the Bureau of Land Management, the Department of Treasury, Office of Foreign Asset Controls, state and international environmental agencies and many others. We are unaware of any material unreserved liabilities in connection with our compliance with such laws. New laws, regulations and enforcement policies may result in additional, presently unquantifiable or unknown, costs or liabilities. The Company is involved in various claims, regulatory agency audits and pending or threatened legal actions involving a variety of matters. The Company maintains insurance that covers many of the claims arising from risks associated with the business activities of the Company, including claims for premises liability, product liability and other such claims. The Company carries substantial insurance to cover such risks above a self-insured retention. The Company believes, and the Company’s experience has been, that such insurance has been enough to cover any such material risks. See Item 1A. Risk Factors. The Company is also a party to claims, threatened and actual litigation, private arbitration, internal investigations of potential regulatory and compliance matters which arise from legacy businesses that the Company has acquired over many years and from the Company’s current ordinary day-to-day business activities. These regulatory matters and disputes involve private parties and/or government authorities, which assert claims against the Company for a broad spectrum of potential claims including: employment law claims, collective actions or class action claims under employment laws, intellectual property claims, (such as alleged patent infringement, and/or misappropriation of trade secrets), premises liability claims, environmental claims, product liability claims, warranty claims, personal injury claims arising from exposure to or use of allegedly defective products, alleged regulatory violations, alleged violations of anti-corruption and anti-bribery laws and other commercial claims seeking recovery for alleged actual or exemplary damages or fines and penalties. Such claims involve various theories of liability which include: negligence, strict liability, product liability, and other theories of liability. For some of these contingent claims, the Company’s insurance coverage is inapplicable or an exclusion to coverage may apply. In such instances, settlement or other resolution of such claims, individually or collectively, could have a material financial or reputational impact on the Company. As of March 31, 2021, the Company recorded reserves in an amount believed to be sufficient, given the range of potential outcomes, for contingent liabilities representing all contingencies believed to be probable. These reserves include all costs expected for reclamation of a closed barite mine and product liability claims, as well as other circumstances involving material claims. Risks and Uncertainties The Company has assessed the potential for additional losses above the amounts accrued as well as potential losses for matters that are not probable but are reasonably possible. The litigation process as well as the outcome of regulatory oversight is inherently uncertain, and our best judgement concerning the probable outcome of litigation or regulatory enforcement matters may prove to be incorrect in some instances. The total potential loss on these matters cannot be determined; however, in our opinion, any ultimate liability, to the extent not otherwise provided for, will not materially affect our financial position, cash flow or results of operations. These estimated liabilities are based on the Company’s assessment of the nature of these matters, their progress toward resolution, the advice of legal counsel and outside experts as well as management’s experience. Because of uncertainty and risk inherent to litigation and arbitration, actual liabilities incurred may exceed our estimated liabilities and reserves, which could have a material financial or reputational impact on the Company.In many instances, the Company’s products and services embody or incorporate trade secrets or patented inventions. From time to time, we are engaged in disputes concerning protection of trade secrets and confidential information, patents and other intellectual property rights. Such disputes frequently involve complex, factual, technical and/or legal issues which result in high costs to adjudicate our rights and difficulty in predicting the ultimate outcome. Because of the importance of the Company’s intellectual property to the Company’s performance, an adverse result in such disputes could result in the loss of revenue from royalties or a decline in sales of products protected by patents, which could materially and adversely impact our financial performance. Further, in some instances, direct or indirect consumers of our products and services, entities providing financing for purchases of our products and services or members of the supply chain for our products and services have become involved in governmental investigations, internal investigations, political or other enforcement matters. In such circumstances, such investigations may adversely impact the ability of consumers of our products, entities providing financial support to such consumers or entities in the supply chain to timely perform their business plans or to timely perform under agreements with us. We may, from time to time, become involved in these investigations, at substantial cost to the Company. We also are subject to trade regulations, supply chain regulations, and other regulatory compliance in which the laws and regulations of different jurisdictions conflict or these regulations may conflict with contractual terms. In such circumstances, our compliance with U.S. laws and regulations may subject us to risk of fines, penalties or contractual liability in other jurisdictions. Our efforts to actively manage such risks may not always be successful which could lead to negative impacts on revenue or earnings. The Company is exposed to customs and regulatory risk in the countries in which we do business or to which we transport goods. For example, the effects of the United Kingdom’s withdrawal from the European Union, known as Brexit, may have a negative impact on our results from operations. Uncertainty concerning the legal and regulatory risks of Brexit, include: (i) supply chain risks resulting from lack of trade agreements, the implementation of new trade agreements, and other potential changes in customs administrations or tariffs; (ii) revenue risk, loss of customers or increased costs; (iii) delays in delivery of materials to the Company or delay in delivery by the Company; and (iv) the need for renegotiation of agreements; and other business disruptions. In addition, trade regulations, export controls, and other laws may adversely impact our ability to do business in certain countries, e.g.: Iran, Syria, Russia, China and Venezuela. Such trade regulations can be complex and present compliance challenges which could result in future liabilities . COVID-19 The COVID-19 pandemic continues to adversely impact many jurisdictions and disrupt normal economic activities. The demand for energy continues to be constrained with adverse consequences for our customers and for the Company. As a result, the Company may be exposed to additional liabilities and risks. Due to these market conditions, demand for our products and services has declined. Our customers may attempt to cancel or delay projects, cancel contracts or may invoke force majure clauses. Our customers may also seek to delay or may default on their payments to us. Further, we have seen, and expect to see, an increasing number of energy companies filing bankruptcy. Our collection of receivables could be materially delayed and/or impaired. The Company also may be exposed to liabilities resulting from operational delays due to supply chain disruption and closure or limitations imposed on our facilities and work force, from “shelter in place” orders around the world. The Company’s ability to perform services could also be impaired and the Company could be exposed to liabilities resulting from interruption in its ability to perform due to limited manpower and travel restrictions. These potential operational and service delays resulting from the COVID-19 pandemic could result in contractual or other legal claims from our customers. At this time, it is not possible to quantify these risks, but the combination of these factors could have a material impact on our financial results.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	1 5 . Recently Adopted Accounting Standards In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” This ASU eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of accounting for income taxes. ASU 2019-12 is effective for interim and annual reporting periods beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU 2019-12 for the first quarter of 2021 with no material impact on the company’s financial position, results of operations and cash flows. Recently Issued Accounting Standards In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)” This ASU applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Management is currently assessing the impact of adopting ASU 2020-04 on the company’s financial position, results of operations and cash flows.
