	Nature of Business
	We design, construct, manufacture and sell comprehensive systems, components, and products used in oil and gas drilling and production, provide oilfield services and supplies, and distribute products and provide supply chain integration services to the upstream oil and gas industry. Our revenues and operating results are directly related to the level of worldwide oil and gas drilling and production activities and the profitability and cash flow of oil and gas companies, drilling contractors and oilfield service companies, which in turn are affected by current and anticipated prices of oil and gas. Oil and gas prices have been, and are likely to continue to be, volatile.
	Basis of Consolidation
	The accompanying Consolidated Financial Statements include the accounts of National Oilwell Varco, Inc. and its consolidated subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Investments that are not wholly-owned, but where we exercise control, are fully consolidated with the equity held by minority owners and their portion of net income (loss) reflected as noncontrolling interests in the accompanying consolidated financial statements. Investments in unconsolidated affiliates, over which we exercise significant influence, but not control, are accounted for by the equity method.
	On May 30, 2014, the Company completed the spin-off of its distribution business into an independent public company named NOW Inc. In conjunction with the spin-off of NOW Inc. the Company reviewed its reporting and management structure, and effective April 1, 2014, reorganized the Rig Technology, Petroleum Services & Supplies and remaining operations of Distribution & Transmission reporting segments into four new reporting segments. The new reporting segments are Rig Systems, Rig Aftermarket, Wellbore Technologies and Completion & Production Solutions. As a result of the reorganization, all prior periods are presented on this basis. Results of operations related to NOW Inc. have been classified as discontinued operations in all periods presented on Form 10-K.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies
	Fair Value of Financial Instruments
	The carrying amounts of financial instruments including cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase.
	Derivative Financial Instruments
	Accounting Standards Codification (“ASC”) Topic 815, “Derivatives and Hedging” (“ASC Topic 815”) requires companies to recognize all derivative instruments as either assets or liabilities in the Consolidated Balance Sheet at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation.
	The Company records all derivative financial instruments at their fair value in its Consolidated Balance Sheet. Except for certain non-designated hedges discussed below, all derivative financial instruments that the Company holds are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Such arrangements typically have terms between two and 24 months, but may have longer terms depending on the underlying cash flows being hedged, typically related to the projects in our backlog.
	Inventories
	Inventories consist of raw materials, work-in-process and oilfield and industrial finished products, manufactured equipment and spare parts. Inventories are stated at the lower of cost or market using the first-in, first-out or average cost methods. Allowances for excess and obsolete inventories are determined based on our historical usage of inventory on-hand as well as our future expectations related to our installed base and the development of new products. The allowance, which totaled $370 million and $396 million at December 31, 2014 and 2013, respectively, is the amount necessary to reduce the cost of the inventory to its net realizable value.
	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost. Expenditures for major improvements that extend the lives of property and equipment are capitalized while minor replacements, maintenance and repairs are charged to operations as incurred. Disposals are removed at cost less accumulated depreciation with any resulting gain or loss reflected in operations. Depreciation is provided using the straight-line method over the estimated useful lives of individual items. Depreciation expense was $413 million, $381 million and $315 million for the years ended December 31, 2014, 2013 and 2012, respectively. The estimated useful lives of the major classes of property, plant and equipment are included in Note 6 to the consolidated financial statements.
	Long-lived Assets
	We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets are impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. The carrying value of assets used in operations that are not recoverable is reduced to fair value if lower than carrying value. In determining the fair market value of the assets, we consider market trends and recent transactions involving sales of similar assets, or when not available, discounted cash flow analysis. There have been no impairments of long-lived assets for the years ended December 31, 2014, 2013 and 2012.
	Intangible Assets
	The Company has approximately $8.5 billion of goodwill and $4.4 billion of identified intangible assets at December 31, 2014.
	Goodwill is identified by segment as follows (in millions):

	Identified intangible assets with determinable lives consist primarily of customer relationships, trademarks, trade names, patents, and technical drawings acquired in acquisitions, and are being amortized on a straight-line basis over the estimated useful lives of 2-30 years. Amortization expense of identified intangibles is expected to be approximately $340 million in each of the next five years. Included in intangible assets are approximately $540 million of indefinite-lived trade names.
	The net book values of identified intangible assets are identified by segment as follows (in millions):

	Total identified intangibles		$	6,559		$	(2,115	)	$	4,444
	Asset Impairment
	Generally accepted accounting principles require the Company to test goodwill and other indefinite-lived intangible assets for impairment at least annually or more frequently whenever events or circumstances occur indicating that goodwill or other indefinite-lived intangible assets might be impaired. Events or circumstances which could indicate a potential impairment include (but are not limited to) a significant reduction in worldwide oil and gas prices or drilling; a significant reduction in profitability or cash flow of oil and gas companies or drilling contractors; a significant reduction in worldwide well remediation activity; a significant reduction in capital investment by other oilfield service companies; or a significant increase in worldwide inventories of oil or gas.
	The annual impairment test is performed during the fourth quarter of each year. The valuation techniques used in the annual test were consistent with those used during previous testing. The inputs used in the annual test were updated for current market conditions and forecasts. During the review of its 2014 annual impairment test, the calculated fair values for all of the Company’s reporting units were in excess of the respective reporting unit’s carrying value. Also, the fair value for all of the Company’s intangible assets with indefinite lives were in excess of the respective asset carrying values, with two exceptions. These intangible assets, which represents a trade names within the Company’s Wellbore Technologies segment, had a calculated fair value approximately $104 million below its carrying value. The impairment charge was primarily the result of the substantial decline in oil prices during the fourth quarter of 2014, declines in forecasts in rig activity for 2015 and a decline in revenue forecast for the segment for 2015.
	Foreign Currency
	The functional currency for most of our foreign operations is the local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income (loss). Revenues and expenses are translated at average exchange rates in effect during the period. Certain other foreign operations, including our operations in Norway, use the U.S. dollar as the functional currency. Accordingly, financial statements of these foreign subsidiaries are remeasured to U.S. dollars for consolidation purposes using current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets and related elements of expense. Revenue and expense elements are remeasured at rates that approximate the rates in effect on the transaction dates. For all operations, gains or losses from remeasuring foreign currency transactions into the functional currency are included in income. Net foreign currency transaction gains (losses) were $20 million, ($24) million and ($18) million for the years ending December 31, 2014, 2013 and 2012, respectively, and are included in other income (expense) in the accompanying statement of operations.
	Historically, the Venezuelan government has devalued the country’s currency. During the first quarter of 2013, the Venezuelan government again officially devalued the Venezuelan bolivar against the U.S. dollar. As a result, the Company incurred approximately $12 million in devaluation charges in the first quarter of 2013. The reporting currency of all of the Company’s Venezuela entities is the U.S. dollar. The Company’s net investment in Venezuela was $45 million at December 31, 2014.
	Revenue Recognition
The Company’s products and services are sold based upon purchase orders or contracts with the customer that include fixed or determinable prices and that do not generally include right of return or other similar provisions or other significant post delivery obligations. Except for certain construction contracts and drill pipe sales described below, the Company records revenue at the time its manufacturing process is complete, the customer has been provided with all proper inspection and other required documentation, title and risk of loss has passed to the customer, collectability is reasonably assured and the product has been delivered. Customer advances or deposits are deferred and recognized as revenue when the Company has completed all of its performance obligations related to the sale. The Company also recognizes revenue as services are performed. The amounts billed for shipping and handling cost are included in revenue and related costs are included in cost of sales.
Revenue Recognition under Long-term Construction Contracts
The Company uses the percentage-of-completion method to account for certain long-term construction contracts in the Rig Systems and Completion & Production Solutions segments. These long-term construction contracts include the following characteristics:
	•		the contracts include custom designs for customer specific applications;
	•		the structural design is unique and requires significant engineering efforts; and
	•		construction projects often have progress payments.
This method requires the Company to make estimates regarding the total costs of the project, progress against the project schedule and the estimated completion date, all of which impact the amount of revenue and gross margin the Company recognizes in each reporting period. The Company prepares detailed cost estimates at the beginning of each project. Significant projects and their related costs and profit margins are updated and reviewed at least quarterly by senior management. Factors that may affect future project costs and margins include shipyard access, weather, production efficiencies, availability and costs of labor, materials and subcomponents and other factors. These factors can impact the accuracy of the Company’s estimates and materially impact the Company’s current and future reported earnings.
The asset, “Costs in excess of billings,” represents revenues recognized in excess of amounts billed. The liability, “Billings in excess of costs,” represents billings in excess of revenues recognized.
Drill Pipe Sales
For drill pipe sales, if requested in writing by the customer, delivery may be satisfied through delivery to the Company’s customer storage location or to a third-party storage facility. For sales transactions where title and risk of loss have transferred to the customer but the supporting documentation does not meet the criteria for revenue recognition prior to the products being in the physical possession of the customer, the recognition of the revenues and related inventory costs from these transactions are deferred until the customer takes physical possession.
Service and Product Warranties
The Company provides service and warranty policies on certain of its products. The Company accrues liabilities under service and warranty policies based upon specific claims and a review of historical warranty and service claim experience in accordance with ASC Topic 450 “Contingencies” (“ASC Topic 450”). Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered. The Company monitors the actual cost of performing these discretionary services and adjusts the accrual based on the most current information available.
The changes in the carrying amount of service and product warranties are as follows (in millions):
Balance at December 31, 2012		$	194
Net provisions for warranties issued during the year			101
Amounts incurred			(73	)
Currency translation adjustments and other			6
Balance at December 31, 2013		$	228
Net provisions for warranties issued during the year			123
Amounts incurred			(78	)
Currency translation adjustments and other			(1	)
Balance at December 31, 2014		$	272
Income Taxes
The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized.
Concentration of Credit Risk
We grant credit to our customers, which operate primarily in the oil and gas industry. Concentrations of credit risk are limited because we have a large number of geographically diverse customers, thus spreading trade credit risk. We control credit risk through credit evaluations, credit limits and monitoring procedures. We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral, but may require letters of credit for certain international sales. Credit losses are provided for in the financial statements. Allowances for doubtful accounts are determined based on a continuous process of assessing the Company’s portfolio on an individual customer basis taking into account current market conditions and trends. This process consists of a thorough review of historical collection experience, current aging status of the customer accounts, and financial condition of the Company’s customers. Based on a review of these factors, the Company will establish or adjust allowances for specific customers. Accounts receivable are net of allowances for doubtful accounts of approximately $125 million and $132 million at December 31, 2014 and 2013.
Stock-Based Compensation
Compensation expense for the Company’s stock-based compensation plans is measured using the fair value method required by ASC Topic 718 “Compensation – Stock Compensation” (“ASC Topic 718”). Under this guidance the fair value of stock option grants and restricted stock is amortized to expense using the straight-line method over the shorter of the vesting period or the remaining employee service period.
The Company provides compensation benefits to employees and non-employee directors under share-based payment arrangements, including various employee stock option plans.
Total compensation cost that has been charged against income for all share-based compensation arrangements was $101 million, $92 million and $80 million for 2014, 2013 and 2012, respectively. The total income tax benefit recognized in the income statement for all share-based compensation arrangements was $35 million, $28 million and $24 million for 2014, 2013 and 2012, respectively.
Environmental Liabilities
When environmental assessments or remediations are probable and the costs can be reasonably estimated, remediation liabilities are recorded on an undiscounted basis and are adjusted as further information develops or circumstances change.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted 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. Such estimates include but are not limited to, estimated losses on accounts receivable, estimated costs and related margins of projects accounted for under percentage-of-completion, estimated realizable value on excess and obsolete inventory, contingencies, estimated liabilities for litigation exposures and liquidated damages, estimated warranty costs, estimates related to pension accounting, estimates related to the fair value of reporting units for purposes of assessing goodwill and other indefinite-lived intangible assets for impairment and estimates related to deferred tax assets and liabilities, including valuation allowances on deferred tax assets. Actual results could differ from those estimates.
Contingencies
The Company accrues for costs relating to litigation claims and other contingent matters, including liquidated damage liabilities, when such liabilities become probable and reasonably estimable. In circumstances where the most likely outcome of a contingency can be reasonably estimated, we accrue a liability for that amount. Where the most likely outcome cannot be estimated, a range of potential losses is established and if no one amount in that range is more likely than others, the low end of the range is accrued. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Revisions to contingent liabilities are reflected in income in the period in which different facts or information become known or circumstances change that affect the Company’s previous judgments with respect to the likelihood or amount of loss. Amounts paid upon the ultimate resolution of contingent liabilities may be materially different from previous estimates and could require adjustments to the estimated reserves to be recognized in the period such new information becomes known.
Net Income Attributable to Company Per Share

Cash dividends per share		$	1.64		$	0.91		$	0.49
ASC Topic 260, “Earnings Per Share” (“ASC Topic 260”) 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 attributable to Company allocated to these participating securities was immaterial for the years ended December 31, 2014, 2013 and 2012 and therefore not excluded from net income attributable to Company per share calculation. The Company had stock options outstanding that were anti-dilutive totaling 8 million, 7 million, and 5 million at December 31, 2014, 2013 and 2012, respectively.
Recently Issued Accounting Standards
In April 2014, the Financial Accounting Standards Board issued Accounting Standard Update No. 2014-08 “Reporting Discontinued Operations and Disclosures of Disposals of Components of and Entity” (ASU No. 2014-08), which is an update for Accounting Standards Codification Topic No. 205 “Presentation of Financial Statements” and Topic No. 360 “Property, Plant and Equipment’. This update changes the requirements of reporting discontinued operations. Under the amended guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The amendments in this update are effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Although early adoption is permitted, the Company did not elect to apply the guidance of ASU No. 2014-08 to the spin-off of NOW. The adoption of this update concerns presentation and disclosure only as it relates to our consolidated financial statements. The Company expects the impact of ASU No. 2014-08 on its consolidated financial position and results of operations to be immaterial.
In May 2014, the FASB issued Accounting Standard Update No. 2014-09 “Revenue from Contracts with Customers” (ASU No. 2014-09), which supersedes the revenue recognition requirements in Accounting Standard Codification Topic No. 605 “Revenue Recognition” and most industry-specific guidance. This update requires that entities recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. ASU No. 2014-09 is effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years. The Company is currently assessing the impact of the adoption of ASU No. 2014-09 on its consolidated financial position and results of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	3. Derivative Financial Instruments
	The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is foreign currency exchange rate risk. Forward contracts against various foreign currencies are entered into to manage the foreign currency exchange rate risk on forecasted revenues and expenses denominated in currencies other than the functional currency of the operating unit (cash flow hedge). Other forward exchange contracts against various foreign currencies are entered into to manage the foreign currency exchange rate risk associated with certain firm commitments denominated in currencies other than the functional currency of the operating unit (fair value hedge). In addition, the Company will enter into non-designated forward contracts against various foreign currencies to manage the foreign currency exchange rate risk on recognized nonfunctional currency monetary accounts (non-designated hedge).
	At December 31, 2014, the Company has determined that the fair value of its derivative financial instruments representing assets of $53 million and liabilities of $399 million (primarily currency related derivatives) are determined using level 2 inputs (inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability) in the fair value hierarchy as the fair value is based on publicly available foreign exchange and interest rates at each financial reporting date. At December 31, 2014, the net fair value of the Company’s foreign currency forward contracts totaled a net liability of $346 million.
	At December 31, 2014, the Company’s financial instruments do not contain any credit-risk-related or other contingent features that could cause accelerated payments when the Company’s financial instruments are in net liability positions. We do not use derivative financial instruments for trading or speculative purposes.
	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. The Company hedges portions of its forecasted revenues and expenses denominated in nonfunctional currencies with forward contracts. When the U.S. dollar strengthens against the foreign currencies, the decrease in present value of future foreign currency revenues and expenses is offset by gains in the fair value of the forward contracts designated as hedges. Conversely, when the U.S. dollar weakens, the increase in the present value of future foreign currency cash flows is offset by losses in the fair value of the forward contracts.
	For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is subject to a particular currency risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of Other Comprehensive Income 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 remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion), or hedge components excluded from the assessment of effectiveness, is recognized in the Consolidated Statements of Income during the current period.
	At December 31, 2014 and 2013, the Company had the following outstanding foreign currency forward contracts that were entered into to hedge nonfunctional currency cash flows from forecasted revenues and expenses (in millions):

	Non-designated Hedging Strategy
	The Company enters into forward exchange contracts to hedge certain nonfunctional currency monetary accounts. The purpose of the Company’s foreign currency hedging activities is to protect the Company from risk that the eventual U.S. dollar equivalent cash flows from the nonfunctional currency monetary accounts will be adversely affected by changes in the exchange rates.
	For derivative instruments that are non-designated, the gain or loss on the derivative instrument subject to the hedged risk (i.e., nonfunctional currency monetary accounts) is recognized in other income (expense), net in current earnings.

Acquisitions and Investments	4. Acquisitions and Investments
	2014
	In the year ended December 31, 2014, the Company completed 10 acquisitions for an aggregate purchase price of $291 million, net of cash acquired. The Company has preliminarily allocated $ 59 million to identifiable intangible assets and $167 million to goodwill. The amount allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired. Goodwill specifically includes the expected synergies and other benefits that the Company believes will result from combining its operations with those of businesses acquired and other intangible assets that do not qualify for separate recognition, such as assembled workforce in place at the date of acquisition. Goodwill resulting from the acquisitions is not deductible for tax purposes.
	2013
	On February 20, 2013, the Company completed its acquisition of all of the shares of Robbins & Myers, Inc. (“R&M”), a U.S.-based designer and manufacturer of products and systems for the oil and gas industry. Under the merger agreement for this transaction, R&M shareholders received $60.00 in cash for each common share for an aggregate purchase price of $2,378 million, net of cash acquired. In addition to R&M, the Company completed five acquisitions and other investments for an aggregate purchase price of $19 million, net of cash acquired.
	The Company has included the financial results of R&M in its consolidated financial statements as of the date of acquisition with components of the R&M operations included in each of the Company’s segments. The Company believes the acquisition of R&M will advance its strategic goal of providing a broader selection of products and services to its customers.
	The following table displays the total purchase price allocation for the R&M acquisition. The table summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition (in millions):
	Current assets, net of cash acquired		$	428
	Property, plant and equipment			250
	Intangible assets			894
	Goodwill			1,590
	Other assets			49
	Total assets acquired			3,211
	Current liabilities			186
	Deferred taxes			524
	Other liabilities			123
	Total liabilities			833
	Cash consideration, net of cash acquired		$	2,378
	The Company has allocated $894 million to identifiable intangible assets (19 year weighted-average life). The intangible assets are amortizable and are comprised of: $635 million of customer relationships (18 year weighted-average life), $170 million of patents (20 year weighted-average life), $86 million of trademarks (20 year weighted-average life), and $3 million of other intangible assets (1 year weighted-average life). The amount allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired. Goodwill specifically includes the expected synergies and other benefits that the Company believes will result from combining its operations with those of businesses acquired and other intangible assets that do not qualify for separate recognition, such as assembled workforce in place at the date of acquisition. Goodwill resulting from the R&M acquisition is not deductible for tax purposes. Pro forma information is not included because the results of the acquired operations would not have materially impacted the Company’s consolidated operating results.
	2012
	In the year ended December 31, 2012, the Company completed 17 acquisitions for an aggregate purchase price of $2,880 million, net of cash acquired. These acquisitions included:
		•		All the shares of NKT Flexibles I/S (“NKT”), a Denmark-based designer and manufacturer of flexible pipe products and systems for the offshore oil and gas industry, acquired on April 4, 2012. The Company reported the NKT results within its Completion & Production Solutions segment from the date of acquisition.
		•		All the shares of Enerflow Industries Inc. (U.S.) and certain assets of Enerflow Industries Inc. (Canada) (“Enerflow”), a Canada-based fabricator and manufacturer of pressure pumping, blending, and cementing equipment for use primarily in Canada and the U.S., acquired on May 16, 2012. The Company reported the Enerflow results within its Completion & Production Solutions segment from the date of acquisition.
		•		All the shares of Wilson Distribution Holdings (“Wilson”), a U.S.-based distributor of pipe, valves and fittings as well as mill, tool and safety products and services, acquired on May 31, 2012. The Company reported the Wilson results within its discontinued operations from the date of acquisition through May 30, 2014, the date of the spin-off of NOW Inc.
		•		All the shares of CE Franklin Ltd. (“CE Franklin”), a Canada-based distributor of pipe, valves, flanges, fittings, production equipment, tubular products and other general oilfield supplies to oil and gas producers in Canada as well as to the oil sands, refining, heavy oil, petrochemical, forestry and mining industries, acquired on July 19, 2012. The Company reported the CE Franklin results within its discontinued operations from the date of acquisition through May 30, 2014, the date of the spin-off of NOW Inc.
		•		All the shares of Fiberspar Corporation (“Fiberspar”), a U.S.-based manufacturer of fiberglass-reinforced spoolable pipe for the oil and gas industry, acquired on October 10, 2012. The Company reported the Fiberspar results within its Wellbore Technologies segment from the date of acquisition.

	Long-term debt			1
	Other liabilities			206
	Total liabilities			792
	Cash consideration, net of cash acquired		$	2,880
	The Company allocated $981 million to intangible assets (18 year weighted-average life). The intangible assets are amortizable and are comprised of: $473 million of customer relationships (20 year weighted-average life), $159 million of trademarks (16 year weighted-average life), and $348 million of other intangible assets (17 year weighted-average life). Goodwill specifically includes the expected synergies and other benefits that the Company believes will result from combining its operations with those of businesses acquired and other intangible assets that do not qualify for separate recognition, such as assembled workforce in place at the date of each acquisition. The $1,000 million allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired. Goodwill resulting from the NKT and CE Franklin acquisitions and a portion of the Enerflow acquisition is not deductible for tax purposes. Pro forma information is not included because the results of the acquired operations would not have materially impacted the Company’s consolidated operating results.
	Each of the acquisitions was accounted for using the purchase method of accounting and, accordingly, the results of operations of each business are included in the consolidated results of operations from the date of acquisition. A summary of the acquisitions follows (in millions):

	The Company has a $3.5 billion, five-year unsecured revolving credit facility which expires September 28, 2018. The Company also has a commercial paper program that is supported by its revolving credit facility. At December 31, 2014, the Company had no commercial paper borrowings and no borrowings against its revolving credit facility. Funds available under the Company’s revolving credit facility were $2,481 million due to $1,019 million in outstanding letters of credit issued under the facility. Interest under this multicurrency facility is based upon LIBOR, NIBOR or EURIBOR plus 0.875% subject to a ratings-based grid, or the U.S. prime rate. The credit facility contains a financial covenant regarding maximum debt to capitalization and the Company was in compliance at December 31, 2014.
	The Company also had $2,969 million of additional outstanding letters of credit at December 31, 2014, primarily in Norway, that are under various bilateral committed letter of credit facilities. Other letters of credit are issued as bid bonds, advanced payment bonds and performance bonds.
	At December 31, 2014 and 2013, the fair value of the Company’s unsecured Senior Notes approximated $2,974 million and $3,023 million, respectively. The fair value of the Company’s debt is estimated using Level 2 inputs in the fair value hierarchy and is based on quoted prices for those or similar instruments. At both December 31, 2014 and 2013, the carrying value of the Company’s unsecured Senior Notes approximated $3,143 million.

Employee Benefit Plans	12 Months Ended

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	10. Employee Benefit Plans
	We have benefit plans covering substantially all of our employees. Defined-contribution benefit plans cover most of the U.S. and Canadian employees, and benefits are based on years of service, a percentage of current earnings and matching of employee contributions. Employees in our Norwegian operations can elect to participate in a defined-contribution plan in lieu of a local defined benefit plan. For the years ended December 31, 2014, 2013 and 2012, expenses for defined-contribution plans were $115 million, $96 million, and $82 million, respectively, and all funding is current.
	Certain retired or terminated employees of predecessor or acquired companies participate in a defined benefit plan in the United States. None of the participants in this plan are eligible to accrue benefits. In addition, 1,081 U.S. retirees and spouses participate in defined benefit health care plans of predecessor or acquired companies that provide postretirement medical and life insurance benefits. Active employees are ineligible to participate in any of these defined benefit plans. Our subsidiaries in the United Kingdom and Norway also have defined benefit pension plans covering virtually all of their employees.
	As a result of the Robbins & Myers acquisition in February of 2013, the Company acquired four qualified, defined benefit, noncontributory pension plans for certain U.S. employees, an unfunded defined benefit pension plan for eligible employees in Germany, as well as two defined benefit, one contributory, pension plans in the U.K. The U.S. pension plans are closed to all new participants and there are no further benefit accruals under these plans. In addition, 230 U.S. employees covered by a collective bargaining agreement participate in a health care plan that provides postretirement medical benefits (which also covers approximately 400 retirees and dependents). The arrangements in Germany and the U.K. are all closed to new entrants, but benefits continue to accrue for current participants.
	During 2014 the Company sold certain industrial assets and the impact on defined benefit plans is reflected in the table below.
	Net periodic benefit cost for our defined benefit plans aggregated $7 million, $10 million and $10 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	The change in benefit obligation, plan assets and the funded status of the defined benefit pension plans in the United States, United Kingdom, Norway, Germany and the Netherlands and defined postretirement plans in the United States, using a measurement date of December 31, 2014 and 2013, is as follows (in millions):

	Assumed long-term rates of return on plan assets, discount rates and rates of compensation increases vary for the different plans according to the local economic conditions. The assumption rates used for benefit obligations are as follows:

	International plans	3.50% - 5.53%		3.50% - 5.82%	4.50% - 6.51%
	In determining the overall expected long-term rate of return for plan assets, the Company takes into consideration the historical experience as well as future expectations of the asset mix involved. As different investments yield different returns, each asset category is reviewed individually and then weighted for significance in relation to the total portfolio.
	The majority of our plans have projected benefit obligations in excess of plan assets.
	The Company expects to pay future benefit amounts on its defined benefit plans of $41 million for each of the next five years and aggregate payments of $420 million.
	Plan Assets
	The Company and its investment advisers collaboratively reviewed market opportunities using historic and statistical data, as well as the actuarial valuation reports for the plans, to ensure that the levels of acceptable return and risk are well-defined and monitored. Currently, the Company’s management believes that there are no significant concentrations of risk associated with plan assets. Our pension investment strategy worldwide prohibits a direct investment in our own stock.
	The following table sets forth by level, within the fair value hierarchy, the Plan’s assets carried at fair value (in millions):

	The Company’s reporting currency is the U.S. dollar. 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 or loss in accordance with ASC Topic 830 “Foreign Currency Matters” (“ASC Topic 830”). For the years ended December 31, 2014 and 2013 a majority of these local currencies weakened against the U.S. dollar resulting in a net other comprehensive loss of $543 million and $90 million, respectively, upon the translation from local currencies to the U.S. dollar. Due to the sale of non-core industrial businesses, $11 million of currency translation losses and $25 million of currency translation gains were reclassified from accumulated other comprehensive income (loss) into other income (expense), net in the Consolidated Statements of Income for the years ended December 31, 2014 and 2013 respectively. For the year ended December 31, 2012 a majority of these local currencies strengthened against the U.S. dollar resulting in a net other comprehensive income of $64 million.
	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 to which they are designed to hedge are realized. The movement in other comprehensive income (loss) from period to period will be the result of the combination of changes in fair value for open derivatives and the outflow of other comprehensive income (loss) related to cumulative changes in the fair value of derivatives that have settled in the current or prior periods. The accumulated effect was other comprehensive loss of $233 million (net of tax of $89 million) for the year ended December 31, 2014, other comprehensive loss of $37 million (net of tax of $18 million) for the year ended December 31, 2013, and other comprehensive income of $99 million (net of tax of $39 million) for the year ended December 31, 2012.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies
	We have received U.S. federal grand jury subpoenas and subsequent inquiries from U.S. governmental agencies requesting records related to our compliance with U.S. export trade laws and regulations. We have cooperated fully with agents from the U.S. Department of Justice (“DOJ”), the Department of Commerce Bureau of Industry and Security (“BIS”), the United States Department of Treasury, Office of Foreign Assets Control (“OFAC”), and U.S. Immigration and Customs Enforcement in responding to the inquiries. We have also cooperated with an informal inquiry from the Securities and Exchange Commission in connection with the inquiries previously made by the aforementioned federal agencies. We have conducted our own internal review of this matter. At the conclusion of our internal review in the fourth quarter of 2009, we identified possible areas of concern and discussed these areas of concern with the relevant agencies. We are currently negotiating a potential resolution with the agencies involved related to these matters. We currently anticipate that any administrative fine or penalty agreed to as part of a resolution would be within established accruals, and would not have a material effect on our financial position or results of operations. To the extent a resolution is not negotiated, we cannot predict the timing or effect that any resulting government actions may have on our financial position or results of operations.
	On February 20, 2013, the Company acquired Robbins & Myers, Inc. (“R&M”). R&M was subject to an ongoing investigation by the DOJ and the BIS regarding potential export controls violations arising from certain shipments by R&M’s Belgian (“RMB”) subsidiary. The alleged violations involved less than $75,000 in goods in 2005 and 2006. The settlement was negotiated by R&M before NOV’s acquisition of R&M. During the third quarter of 2014, the parties executed a Non-Prosecution Agreement (“NPA”) to memorialize the previously negotiated settlement. Accordingly, in the third quarter of 2014, R&M paid a fine of $1,033,000 to the DOJ and $600,000 to BIS, and RMB pleaded guilty to criminal violations of U.S. trade restrictions. RMB entered into a Plea Agreement and was sentenced to five years probation. Under the NPA, R&M, for two years unless otherwise changed pursuant to the NPA must implement a specified compliance program and periodically certify compliance with U.S. Trade Sanction Laws.
	A gain of $102 million was recognized in the third quarter of 2013 related to a legal settlement. The gain was included in revenue of the Company’s Wellbore Technologies segment.
	In addition, we are involved in various other claims, regulatory agency audits and pending or threatened legal actions involving a variety of matters. As of December 31, 2014, the Company recorded an immaterial amount for contingent liabilities representing all contingencies believed to be probable. The Company has also 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 total potential loss on these matters cannot be determined; however, in our opinion, any ultimate liability, to the extent not otherwise provided for and except for the specific cases referred to above, will not materially affect our financial position, cash flow or results of operations. As it relates to the specific cases referred to above we currently anticipate that any administrative fine or penalty agreed to as part of a resolution would be within established accruals, and would not have a material effect on our financial position or results of operations. To the extent a resolution is not negotiated as anticipated, we cannot predict the timing or effect that any resulting government actions may have on 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 intention and experience.
	Our business is affected both directly and indirectly by governmental laws and regulations relating to the oilfield service industry in general, as well as by environmental and safety regulations that specifically apply to our business. Although we have not incurred material costs in connection with our compliance with such laws, there can be no assurance that other developments, such as new environmental laws, regulations and enforcement policies hereunder may not result in additional, presently unquantifiable, costs or liabilities to us.
	The Company leases certain facilities and equipment under operating leases that expire at various dates through 2066. These leases generally contain renewal options and require the lessee to pay maintenance, insurance, taxes and other operating expenses in addition to the minimum annual rentals. Rental expense related to operating leases approximated $390 million, $336 million, and $281 million in 2014, 2013 and 2012, respectively.
	Future minimum lease commitments under noncancellable operating leases with initial or remaining terms of one year or more at December 31, 2014, are payable as follows (in millions):

Equity [Abstract]
Common Stock	13. Common Stock
	National Oilwell Varco has authorized 1 billion shares of $.01 par value common stock. The Company also has authorized 10 million shares of $.01 par value preferred stock, none of which is issued or outstanding.
	Cash dividends aggregated $703 million and $389 million for the years ended December 31, 2014 and 2013, respectively. The declaration and payment of future dividends is at the discretion of the Company’s Board of Directors and will be dependent upon the Company’s results of operations, financial condition, capital requirements and other factors deemed relevant by the Company’s Board of Directors.
	On September 30, 2014, the Company announced that its Board of Directors authorized a share repurchase program to purchase up to $3 billion of the Company’s outstanding common stock. The Company may repurchase its shares on the open market at prevailing market prices. The timing and actual number of shares repurchased will depend on a variety of factors including market conditions and regulatory considerations. The duration of the share repurchase program is 36 months, although it may be increased, extended, suspended or discontinued without prior notice. The Company intends to fund the repurchases using its available U.S. cash balances, which may involve the repatriation of foreign earnings not indefinitely reinvested. However, depending on U.S. cash balances, the Company may choose to borrow against its revolving credit facility, its commercial paper program or new debt issuances to finance the repurchases. As shares are repurchased, they are constructively retired and returned to an unissued state. At December 31, 2014, the Company repurchased 11.6 million shares under the program for an aggregate amount of $779 million.
	Stock Options
	Under the terms of National Oilwell Varco’s Long-Term Incentive Plan, as amended, 39.5 million shares of common stock are authorized for the grant of options to officers, key employees, non-employee directors and other persons. Options granted under our stock option plan generally vest over a three-year period starting one year from the date of grant and expire ten years from the date of grant. The purchase price of options granted may not be less than the closing market price of National Oilwell Varco common stock on the date of grant. At December 31, 2014, approximately 11.9 million shares were available for future grants.
	We also have inactive stock option plans that were acquired in connection with the acquisitions of Varco International, Inc. in 2005 and Grant Prideco in 2008. We converted the outstanding stock options under these plans to options to acquire our common stock and no further options are being issued under these plans. Stock option information summarized below includes amounts for the National Oilwell Varco Long-Term Incentive Plan and stock plans of acquired companies. Options outstanding at December 31, 2014 under the stock option plans have exercise prices between $8.43 and $77.99 per share, and expire at various dates from January 26, 2015 to December 4, 2024.
	On June 2, 2014, as a result of the spin-off and pursuant to the terms of the Employee Matters Agreement and the Plan, outstanding NOV stock-based awards held by continuing NOV employees were adjusted to generally preserve the intrinsic value of the original award. Outstanding NOV stock-based awards held by employees of NOW were converted into similar NOW stock-based awards, each appropriately adjusted to generally preserve the intrinsic value of the original award. Adjustments to the awards are reflected in the following tables and did not have a material impact to compensation expense.
	Total compensation cost that has been charged against income for all share-based compensation arrangements was $101 million, $92 million and $80 million for 2014, 2013 and 2012, respectively. The total income tax benefit recognized in the income statement for all share-based compensation arrangements was $35 million, $28 million and $24 million for 2014, 2013 and 2012, respectively.

	The weighted-average fair value of options granted during 2014, 2013 and 2012, was approximately $25.60, $24.11 and $30.01 per share, respectively, as determined using the Black-Scholes option-pricing model. The total intrinsic value of options exercised during 2014 and 2013, was $111 million and $64 million, respectively.
	The determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise activity. The use of the Black Scholes model requires the use of extensive actual employee exercise activity data and the use of a number of complex assumptions including expected volatility, risk-free interest rate, expected dividends and expected term.

	The Company used the actual volatility for traded options for the past 10 years prior to option date as the expected volatility assumption required in the Black Scholes model.
	The risk-free interest rate assumption is based upon observed interest rates appropriate for the term of our employee stock options. The dividend yield assumption is based on the history and expectation of dividend payouts. The estimated expected term is based on actual employee exercise activity for the past ten years.
	As stock-based compensation expense recognized in the Consolidated Statement of Income in 2014 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC Topic 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience.
	The following summary presents information regarding outstanding options at December 31, 2014 and changes during 2014 with regard to options under all stock option plans:

	Exercisable at December 31, 2014		5,903,712		$	55.06			5.15		$	85,503,217
	At December 31, 2014, total unrecognized compensation cost related to nonvested stock options was $69 million. This cost is expected to be recognized over a weighted-average period of two years. The total fair value of stock options vested in 2014, 2013 and 2012 was approximately $67 million, $64 million and $55 million, respectively. Cash received from option exercises for 2014, 2013 and 2012 was $108 million, $58 million and $113 million, respectively. The actual tax benefit realized for the tax deductions from option exercises totaled $44 million, $39 million and $42 million for 2014, 2013 and 2012, respectively. Cash used to settle equity instruments granted under all share-based payment arrangements for 2014, 2013 and 2012 was not material for any period.
	Restricted Shares
	The Company issues restricted stock awards and restricted stock units to officers and key employees in addition to stock options. On February 25, 2014, the Company granted 426,272 shares of restricted stock and restricted stock units with a fair value of $69.00 per share; and performance share awards to senior management employees with potential payouts varying from zero to 436,390 shares. The stock options vest over a three-year period from the grant date while the restricted stock and restricted stock units vest on the third anniversary of the date of grant. The performance share awards can be earned based on performance against established goals over a three-year performance period. The performance share awards are divided into two equal, independent parts that are subject to two separate performance metrics: 50% with a TSR (total shareholder return) goal (the “TSR Award”) and 50% with an internal ROC (return on capital) goal (the “ROC Award”).
	Performance against the TSR goal is determined by comparing the performance of the Company’s TSR with the TSR performance of the members of the OSX index for the three year performance period. Performance against the ROC goal is determined by comparing the performance of the Company’s actual ROC performance average for each of the three years of the performance period against the ROC goal set by the Company’s Compensation Committee.
	On May 14, 2014, the Company granted 18,736 restricted stock awards with a fair value of $68.89 per share. The awards were granted to non-employee members of the board of directors and vest on the first anniversary of the grant date.
	The following summary presents information regarding outstanding restricted shares:

	The balance of unrecognized tax benefits at December 31, 2014 and 2013 was $115 million and $127 million, respectively. Included in the change in the balance of unrecognized tax benefits for the period ended December 31, 2014 was an increase of $3 million of unrecognized tax benefits associated with potential transfer pricing adjustments between foreign jurisdictions and certain operating expenses that may not be deductible in foreign jurisdictions. A $15 million reduction in the balance of unrecognized tax benefits resulted from the lapse of applicable statutes of limitations in the U.S. and foreign jurisdictions, as well as the completion of audits in the U.S. Of the net decrease of $12 million in the balance of unrecognized tax benefits, the entire $12 million was recorded as a decrease of income tax expense in the current year and is reflected in the “other” category in the income tax rate schedule above. These unrecognized tax benefits are included in the balance of other liabilities in the Consolidated Balance Sheet at December 31, 2014. If the $115 million of unrecognized tax benefits accrued at December 31, 2014 are ultimately realized, $42 million would be recorded as a reduction of income tax expense.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):
		2014			2013			2012
	Unrecognized tax benefit at beginning of year	$	127		$	128		$	131
	Additions based on tax positions related to the current year		3			—			2
	Reductions for lapse of applicable statutes of limitations		(15	)		(1	)		(5	)
	Unrecognized tax benefit at end of year	$	115		$	127		$	128
	The Company does not anticipate that the total unrecognized tax benefits will significantly change due to the settlement of audits or the expiration of statutes of limitation within 12 months of this reporting date.
	To the extent penalties and interest would be assessed on any underpayment of income tax, such accrued amounts have been classified as a component of income tax expense in the financial statements consistent with the Company’s policy. During the year ended December 31, 2014, the Company recorded as an increase of income tax expense a $0.5 million net increase of accrued interest and penalties related to uncertain tax positions. At December 31, 2014, the Company has accrued approximately $8.5 million of interest and penalties relating to unrecognized tax benefits. These interest and penalties are included in the balance of other liabilities in the Consolidated Balance Sheet at December 31, 2014.
	The Company is subject to taxation in the United States, various states and foreign jurisdictions. The Company has significant operations in the United States, Norway, Canada, the United Kingdom, the Netherlands, France and Denmark. Tax years that remain subject to examination by major tax jurisdictions vary by legal entity, but are generally open in the U.S. for the tax years ending after 2009 and outside the U.S. for the tax years ending after 2007.
	In the United States, the Company has $20 million of net operating loss carryforwards as of December 31, 2014, of which $4 million will expire in 2025, $13 million will expire in 2026, $1 million will expire in 2027, $1 million will expire in 2029 and $1 million will expire in 2030. The potential benefit of $7 million has been reduced by a $7 million valuation allowance. Future income tax payments will be reduced in the event the Company ultimately realizes the benefit of these net operating losses. If the Company ultimately realizes the benefit of these net operating loss carryforwards, the valuation allowance of $7 million would reduce future income tax expense.
Outside the United States, the Company has $381 million of net operating loss carryforwards as of December 31, 2014, of which $5 million will expire in 2015, $4 million will expire in 2016, $34 million will expire in 2017, $16 million will expire in 2018, $4 million will expire in 2019, $6 million will expire in 2020, $20 million will expire in 2021, $10 million will expire in 2022, $9 million will expire in 2023, $41 million will expire in 2024, $4 million will expire in 2034 and $228 million will carry forward indefinitely. The potential benefit of $98 million has been reduced by a $41 million valuation allowance. Future income tax payments will be reduced in the event the Company ultimately realizes the benefit of these net operating losses. If the Company ultimately realizes the benefit of these net operating loss carryforwards, the valuation allowance of $41 million would reduce future income tax expense.
Also in the United States, the Company has $243 million of excess foreign tax credits as of December 31, 2014, of which $73 million will expire in 2018, $28 million will expire in 2020, and $142 million will expire in 2022. A valuation allowance of $101 million was reversed in 2014, as it is more likely than not these excess foreign tax credits will be utilized before they expire. There is a reserve for uncertain tax positions of $73 million against a portion of these credits.
Undistributed earnings of certain of the Company’s foreign subsidiaries amounted to $5,874 million and $6,045 million at December 31, 2014 and 2013, respectively. Those earnings are considered to be permanently reinvested and no provision for U.S. federal and state income taxes has been made. Distribution of these earnings in the form of dividends or otherwise could result in U.S. federal taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable in various foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practical; however, unrecognized foreign tax credit carryforwards would be available to reduce some portion of the U.S. liability.
Because of the number of tax jurisdictions in which the Company operates, its effective tax rate can fluctuate as operations and the local country tax rates fluctuate. The Company is also subject to audits by federal, state and foreign jurisdictions which may result in proposed assessments. The Company’s future tax provision will reflect any favorable or unfavorable adjustments to its estimated tax liabilities when resolved. The Company is unable to predict the outcome of these matters. However, the Company believes that none of these matters will have a material adverse effect on the results of operations or financial condition of the Company.

Segment Reporting [Abstract]
Business Segments and Geographic Areas	15. Business Segments and Geographic Areas
	Effective April 1, 2014, the Company’s operations were reorganized into four reportable segments: Rig Systems, Rig Aftermarket, Wellbore Technologies and Completion & Production Solutions. Within the four reporting segments, the Company has aggregated two business units under Rig Systems, one business unit under Rig Aftermarket, six business units under Wellbore Technologies and six business units under Completion & Production Solutions for a total of 15 business units. The Company has aggregated each of its business units in one of the four reporting segments based on the guidelines of ASC Topic 280, “Segment Reporting” (“ASC Topic 280”).
	Rig Systems
	The Company’s Rig Systems segment makes and supports the capital equipment and integrated systems needed to drill oil and gas wells on land and offshore. The segment designs, manufactures, and sells land rigs, offshore drilling equipment packages, including installation and commissioning services, and drilling rig components that mechanize and automate the rig process and functionality.
	Equipment and technologies in Rig Systems include: substructures, derricks, and masts; cranes; pipe lifting, racking, rotating, and assembly systems; fluid transfer technologies, such as mud pumps; pressure control equipment, including blowout preventers; power transmission systems, including drives and generators; and rig instrumentation and control systems.
	Rig Systems primarily supports land and offshore drillers. Demand for Rig Systems products primarily depends on drilling contractors’ and oil and gas companies’ capital spending plans, specifically capital expenditures on rig construction and refurbishment.
	Rig Aftermarket
	The Company’s Rig Aftermarket segment provides comprehensive aftermarket products and services to support land rigs and offshore rigs, and drilling rig components manufactured by the Rig Systems segment.
	The segment provides spare parts, repair, and rentals as well as technical support, field service and first well support, field engineering, and customer training through a network of aftermarket service and repair facilities strategically located in major areas of drilling operations.
	Rig Aftermarket primarily supports land and offshore drillers. Demand for Rig Aftermarket products and services primarily depends on overall levels of oilfield drilling activity, which drives demand for spare parts, service, and repair for Rig System’s large installed base of equipment; and secondarily on drilling contractors’ and oil and gas companies’ capital spending plans, specifically capital expenditures on rig refurbishment and re-certification.
	Wellbore Technologies
	The Company’s Wellbore Technologies segment designs, manufactures, rents, and sells a variety of equipment and technologies used to perform drilling operations, and offers services that optimize their performance, including: solids control and waste management equipment and services, drilling fluids, premium drill pipe, wired pipe, tubular inspection and coating services, instrumentation, downhole tools, and drill bits.
	Wellbore Technologies focuses on oil and gas companies and supports drilling contractors, oilfield service companies, and oilfield rental companies. Demand for Wellbore Technologies products and services primarily depends on the level of oilfield drilling activity by oil and gas companies, drilling contractors, and oilfield service companies.
	Completion & Production Solutions
	The Company’s Completion & Production Solutions segment integrates technologies for well completions and oil and gas production. The segment designs, manufactures, and sells equipment and technologies needed for hydraulic fracture stimulation, including pressure pumping trucks and pumps, blenders, sanders, hydration units, injection units, flowline, manifolds and wellheads; well intervention, including coiled tubing units, coiled tubing, and wireline units and tools; onshore production, including composite pipe, surface transfer and progressive cavity pumps, and artificial lift systems; and offshore production, including floating production systems and subsea production technologies.
	Completion & Production Solutions primarily supports service companies and oil and gas companies. Demand for Completion & Production Solutions products depends on the level of oilfield completions and workover activity by oilfield service companies and drilling contractors and capital spending plans by oil and gas companies and oilfield service companies.
	The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies of the Company. The Company evaluates performance of each reportable segment based upon its operating income, excluding non-recurring items.
	The Company had revenues of 7%, 11% and 11% of total revenue from one of its customers for the years ended December 31, 2014, 2013, and 2012, respectively. This customer, Samsung Heavy Industries, is a shipyard acting as a general contractor for its customers, who are drillship owners and drilling contractors. This shipyard’s customers have specified that the Company’s drilling equipment be installed on their drillships and have required the shipyard to issue contracts to the Company.

Eliminations include intercompany transactions conducted between the four reporting segments that are eliminated in consolidation. Intercompany transactions within each reporting segment are eliminated within each reporting segment. Also included in the eliminations column are capital expenditures and total assets related to corporate. Corporate assets consist primarily of cash and fixed assets.

Spinoff_of_Distribution_Busine

Spin-off of Distribution Business	12 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Spin-off of Distribution Business	16. Spin-off of distribution business
	On May 30, 2014, the Company completed the previously announced spin-off (the “spin-off”) of its distribution business into an independent public company named NOW Inc., which trades on the New York Stock Exchange under the symbol “DNOW”. After the close of the New York Stock Exchange on May 30, 2014, the stockholders of record as of May 22, 2014 (the “Record Date”) received one share of NOW Inc. common stock for every four shares of NOV common stock held on the Record Date. No fractional shares of NOW Inc. common stock were distributed. Instead, the transfer agent aggregated any fractional shares into whole shares, sold those whole shares in the open market at prevailing rates and distributed the net cash proceeds, after deducting any taxes required to be withheld and any amount equal to all brokerage charges and commissions, pro rata to each holder who would otherwise have been entitled to receive fractional shares in the distribution.
	In order to effect the spin-off and govern its relationship with NOW after the spin-off, the Company entered into a Separation and Distribution Agreement, a Tax Matters Agreement, an Employee Matters Agreement, a Transition Services Agreement, a Master Distributor Agreement, and a Master Supply Agreement. The Separation and Distribution Agreement governs the terms of the separation of the distribution business from NOV’s other businesses. Generally, the Separation and Distribution Agreement includes agreements between NOW and NOV relating to the restructuring steps needed to be taken to complete the separation, including the assets, equity interests and rights to be transferred, liabilities to be assumed, contracts to be assigned and related matters. The Separation and Distribution Agreement also governs matters relating to indemnification, insurance, litigation responsibility, confidentiality, management, intellectual property (including trademarks) and cooperation.
	The Tax Matters Agreement governs respective rights, responsibilities and obligations of NOV and NOW with respect to deficiencies and refunds, if any, of federal, state, local, and foreign taxes for periods before and after the distribution, as well as taxes attributable to the separation and distribution, and related matters such as the filing of tax returns and the conduct of IRS and other audits. In addition, the Tax Matters Agreement imposes certain restrictions on NOW and its subsidiaries (including restrictions on share issuances, business combinations, sales of assets and similar transactions) that are designed to preserve the generally tax-free status of the separation and distribution.
	The Employee Matters Agreement governs the compensation and employee benefit obligations with respect to the current and former employees of NOV and NOW and generally allocates liabilities and responsibilities relating to employee compensation and benefit plans and programs. The Employee Matters Agreement provides for the treatment of outstanding NOV equity awards. The Employee Matters Agreement also sets forth the general principles relating to employee matters, including with respect to the assignment of employees and the transfer of employees from us to NOW, the assumption and retention of liabilities and related assets, expense reimbursements, workers’ compensation, leaves of absence, the provision of comparable benefits, employee service credits, the sharing of employee information and the duplication or acceleration of benefits.
	The Transition Services Agreement sets forth the terms on which NOV will provide to NOW, and NOW will provide to NOV, on a temporary basis, certain services or functions that the companies historically have shared. Transition services may include administrative, payroll, human resources, data processing, environmental health and safety, financial audit support, financial transaction support, legal support services, IT and network infrastructure systems and various other support and corporate services. The Transition Services Agreement provides for the provision of specified transition services generally for a period of up to 18 months.
	The Master Distributor Agreement provides that NOW will act as a distributor of certain of NOV’s products. Under the Master Supply Agreement, NOW will supply products and provide solutions, including supply chain management solutions, to NOV.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The carrying amounts of financial instruments including cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase.
Derivative Financial Instruments	Derivative Financial Instruments
	Accounting Standards Codification (“ASC”) Topic 815, “Derivatives and Hedging” (“ASC Topic 815”) requires companies to recognize all derivative instruments as either assets or liabilities in the Consolidated Balance Sheet at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation.
	The Company records all derivative financial instruments at their fair value in its Consolidated Balance Sheet. Except for certain non-designated hedges discussed below, all derivative financial instruments that the Company holds are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Such arrangements typically have terms between two and 24 months, but may have longer terms depending on the underlying cash flows being hedged, typically related to the projects in our backlog.
Inventories	Inventories
	Inventories consist of raw materials, work-in-process and oilfield and industrial finished products, manufactured equipment and spare parts. Inventories are stated at the lower of cost or market using the first-in, first-out or average cost methods. Allowances for excess and obsolete inventories are determined based on our historical usage of inventory on-hand as well as our future expectations related to our installed base and the development of new products. The allowance, which totaled $370 million and $396 million at December 31, 2014 and 2013, respectively, is the amount necessary to reduce the cost of the inventory to its net realizable value.
Property, Plant and Equipment	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost. Expenditures for major improvements that extend the lives of property and equipment are capitalized while minor replacements, maintenance and repairs are charged to operations as incurred. Disposals are removed at cost less accumulated depreciation with any resulting gain or loss reflected in operations. Depreciation is provided using the straight-line method over the estimated useful lives of individual items. Depreciation expense was $413 million, $381 million and $315 million for the years ended December 31, 2014, 2013 and 2012, respectively. The estimated useful lives of the major classes of property, plant and equipment are included in Note 6 to the consolidated financial statements.
Long-lived Assets	Long-lived Assets
	We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets are impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. The carrying value of assets used in operations that are not recoverable is reduced to fair value if lower than carrying value. In determining the fair market value of the assets, we consider market trends and recent transactions involving sales of similar assets, or when not available, discounted cash flow analysis. There have been no impairments of long-lived assets for the years ended December 31, 2014, 2013 and 2012.
Intangible Assets	Intangible Assets
	The Company has approximately $8.5 billion of goodwill and $4.4 billion of identified intangible assets at December 31, 2014.
	Goodwill is identified by segment as follows (in millions):
			Rig			Rig			Wellbore			Completion			Discontinued			Total
			Systems			Aftermarket			Technologies			& Production			Operations

	Balance at December 31, 2014		$	1,236		$	877		$	4,357		$	2,069		$	—		$	8,539
	Identified intangible assets with determinable lives consist primarily of customer relationships, trademarks, trade names, patents, and technical drawings acquired in acquisitions, and are being amortized on a straight-line basis over the estimated useful lives of 2-30 years. Amortization expense of identified intangibles is expected to be approximately $340 million in each of the next five years. Included in intangible assets are approximately $540 million of indefinite-lived trade names.
	The net book values of identified intangible assets are identified by segment as follows (in millions):
			Rig Systems			Rig			Wellbore			Completion &			Discontinued			Total
						Aftermarket			Technologies			Production			Operations

	Total identified intangibles		$	6,559		$	(2,115	)	$	4,444
Asset Impairment	Asset Impairment
	Generally accepted accounting principles require the Company to test goodwill and other indefinite-lived intangible assets for impairment at least annually or more frequently whenever events or circumstances occur indicating that goodwill or other indefinite-lived intangible assets might be impaired. Events or circumstances which could indicate a potential impairment include (but are not limited to) a significant reduction in worldwide oil and gas prices or drilling; a significant reduction in profitability or cash flow of oil and gas companies or drilling contractors; a significant reduction in worldwide well remediation activity; a significant reduction in capital investment by other oilfield service companies; or a significant increase in worldwide inventories of oil or gas.
	The annual impairment test is performed during the fourth quarter of each year. The valuation techniques used in the annual test were consistent with those used during previous testing. The inputs used in the annual test were updated for current market conditions and forecasts. During the review of its 2014 annual impairment test, the calculated fair values for all of the Company’s reporting units were in excess of the respective reporting unit’s carrying value. Also, the fair value for all of the Company’s intangible assets with indefinite lives were in excess of the respective asset carrying values, with two exceptions. These intangible assets, which represents a trade names within the Company’s Wellbore Technologies segment, had a calculated fair value approximately $104 million below its carrying value. The impairment charge was primarily the result of the substantial decline in oil prices during the fourth quarter of 2014, declines in forecasts in rig activity for 2015 and a decline in revenue forecast for the segment for 2015.
Foreign Currency	Foreign Currency
	The functional currency for most of our foreign operations is the local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income (loss). Revenues and expenses are translated at average exchange rates in effect during the period. Certain other foreign operations, including our operations in Norway, use the U.S. dollar as the functional currency. Accordingly, financial statements of these foreign subsidiaries are remeasured to U.S. dollars for consolidation purposes using current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets and related elements of expense. Revenue and expense elements are remeasured at rates that approximate the rates in effect on the transaction dates. For all operations, gains or losses from remeasuring foreign currency transactions into the functional currency are included in income. Net foreign currency transaction gains (losses) were $20 million, ($24) million and ($18) million for the years ending December 31, 2014, 2013 and 2012, respectively, and are included in other income (expense) in the accompanying statement of operations.
	Historically, the Venezuelan government has devalued the country’s currency. During the first quarter of 2013, the Venezuelan government again officially devalued the Venezuelan bolivar against the U.S. dollar. As a result, the Company incurred approximately $12 million in devaluation charges in the first quarter of 2013. The reporting currency of all of the Company’s Venezuela entities is the U.S. dollar. The Company’s net investment in Venezuela was $45 million at December 31, 2014.
Revenue Recognition	Revenue Recognition
	The Company’s products and services are sold based upon purchase orders or contracts with the customer that include fixed or determinable prices and that do not generally include right of return or other similar provisions or other significant post delivery obligations. Except for certain construction contracts and drill pipe sales described below, the Company records revenue at the time its manufacturing process is complete, the customer has been provided with all proper inspection and other required documentation, title and risk of loss has passed to the customer, collectability is reasonably assured and the product has been delivered. Customer advances or deposits are deferred and recognized as revenue when the Company has completed all of its performance obligations related to the sale. The Company also recognizes revenue as services are performed. The amounts billed for shipping and handling cost are included in revenue and related costs are included in cost of sales.
	Revenue Recognition under Long-term Construction Contracts
	The Company uses the percentage-of-completion method to account for certain long-term construction contracts in the Rig Systems and Completion & Production Solutions segments. These long-term construction contracts include the following characteristics:
		•		the contracts include custom designs for customer specific applications;
		•		the structural design is unique and requires significant engineering efforts; and
		•		construction projects often have progress payments.
	This method requires the Company to make estimates regarding the total costs of the project, progress against the project schedule and the estimated completion date, all of which impact the amount of revenue and gross margin the Company recognizes in each reporting period. The Company prepares detailed cost estimates at the beginning of each project. Significant projects and their related costs and profit margins are updated and reviewed at least quarterly by senior management. Factors that may affect future project costs and margins include shipyard access, weather, production efficiencies, availability and costs of labor, materials and subcomponents and other factors. These factors can impact the accuracy of the Company’s estimates and materially impact the Company’s current and future reported earnings.
	The asset, “Costs in excess of billings,” represents revenues recognized in excess of amounts billed. The liability, “Billings in excess of costs,” represents billings in excess of revenues recognized.
Drill Pipe Sales	Drill Pipe Sales
	For drill pipe sales, if requested in writing by the customer, delivery may be satisfied through delivery to the Company’s customer storage location or to a third-party storage facility. For sales transactions where title and risk of loss have transferred to the customer but the supporting documentation does not meet the criteria for revenue recognition prior to the products being in the physical possession of the customer, the recognition of the revenues and related inventory costs from these transactions are deferred until the customer takes physical possession.
Service and Product Warranties	Service and Product Warranties
	The Company provides service and warranty policies on certain of its products. The Company accrues liabilities under service and warranty policies based upon specific claims and a review of historical warranty and service claim experience in accordance with ASC Topic 450 “Contingencies” (“ASC Topic 450”). Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered. The Company monitors the actual cost of performing these discretionary services and adjusts the accrual based on the most current information available.
	The changes in the carrying amount of service and product warranties are as follows (in millions):
	Balance at December 31, 2012		$	194
	Net provisions for warranties issued during the year			101
	Amounts incurred			(73	)
	Currency translation adjustments and other			6
	Balance at December 31, 2013		$	228
	Net provisions for warranties issued during the year			123
	Amounts incurred			(78	)
	Currency translation adjustments and other			(1	)
	Balance at December 31, 2014		$	272
Income Taxes	Income Taxes
	The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized.
Concentration of Credit Risk	Concentration of Credit Risk
	We grant credit to our customers, which operate primarily in the oil and gas industry. Concentrations of credit risk are limited because we have a large number of geographically diverse customers, thus spreading trade credit risk. We control credit risk through credit evaluations, credit limits and monitoring procedures. We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral, but may require letters of credit for certain international sales. Credit losses are provided for in the financial statements. Allowances for doubtful accounts are determined based on a continuous process of assessing the Company’s portfolio on an individual customer basis taking into account current market conditions and trends. This process consists of a thorough review of historical collection experience, current aging status of the customer accounts, and financial condition of the Company’s customers. Based on a review of these factors, the Company will establish or adjust allowances for specific customers. Accounts receivable are net of allowances for doubtful accounts of approximately $125 million and $132 million at December 31, 2014 and 2013.
Stock-Based Compensation	Stock-Based Compensation
	Compensation expense for the Company’s stock-based compensation plans is measured using the fair value method required by ASC Topic 718 “Compensation – Stock Compensation” (“ASC Topic 718”). Under this guidance the fair value of stock option grants and restricted stock is amortized to expense using the straight-line method over the shorter of the vesting period or the remaining employee service period.
	The Company provides compensation benefits to employees and non-employee directors under share-based payment arrangements, including various employee stock option plans.
	Total compensation cost that has been charged against income for all share-based compensation arrangements was $101 million, $92 million and $80 million for 2014, 2013 and 2012, respectively. The total income tax benefit recognized in the income statement for all share-based compensation arrangements was $35 million, $26 million and $22 million for 2014, 2013 and 2012, respectively.
Environmental Liabilities	Environmental Liabilities
	When environmental assessments or remediations are probable and the costs can be reasonably estimated, remediation liabilities are recorded on an undiscounted basis and are adjusted as further information develops or circumstances change.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted 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. Such estimates include but are not limited to, estimated losses on accounts receivable, estimated costs and related margins of projects accounted for under percentage-of-completion, estimated realizable value on excess and obsolete inventory, contingencies, estimated liabilities for litigation exposures and liquidated damages, estimated warranty costs, estimates related to pension accounting, estimates related to the fair value of reporting units for purposes of assessing goodwill and other indefinite-lived intangible assets for impairment and estimates related to deferred tax assets and liabilities, including valuation allowances on deferred tax assets. Actual results could differ from those estimates.
Contingencies	Contingencies
	The Company accrues for costs relating to litigation claims and other contingent matters, including liquidated damage liabilities, when such liabilities become probable and reasonably estimable. In circumstances where the most likely outcome of a contingency can be reasonably estimated, we accrue a liability for that amount. Where the most likely outcome cannot be estimated, a range of potential losses is established and if no one amount in that range is more likely than others, the low end of the range is accrued. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Revisions to contingent liabilities are reflected in income in the period in which different facts or information become known or circumstances change that affect the Company’s previous judgments with respect to the likelihood or amount of loss. Amounts paid upon the ultimate resolution of contingent liabilities may be materially different from previous estimates and could require adjustments to the estimated reserves to be recognized in the period such new information becomes known.
Net Income Attributable to Company Per Share	Net Income Attributable to Company Per Share
	The following table sets forth the computation of weighted average basic and diluted shares outstanding (in millions, except per share data):

	Dilutive effect of employee stock options and other unvested stock awards			2			2			2
	Diluted outstanding shares			430			428			427
	Per share data:
	Basic:
	Income from continuing operations		$	5.73		$	5.11		$	5.61
	Income from discontinued operations		$	0.12		$	0.35		$	0.25
	Net income attributable to Company		$	5.85		$	5.46		$	5.86
	Diluted:
	Income from continuing operations		$	5.7		$	5.09		$	5.58
	Income from discontinued operations		$	0.12		$	0.35		$	0.25
	Net income attributable to Company		$	5.82		$	5.44		$	5.83
	Cash dividends per share		$	1.64		$	0.91		$	0.49
	ASC Topic 260, “Earnings Per Share” (“ASC Topic 260”) 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 attributable to Company allocated to these participating securities was immaterial for the years ended December 31, 2014, 2013 and 2012 and therefore not excluded from net income attributable to Company per share calculation. The Company had stock options outstanding that were anti-dilutive totaling 8 million, 7 million, and 5 million at December 31, 2014, 2013 and 2012, respectively.
Recently Issued Accounting Standards	Recently Issued Accounting Standards
	In April 2014, the Financial Accounting Standards Board issued Accounting Standard Update No. 2014-08 “Reporting Discontinued Operations and Disclosures of Disposals of Components of and Entity” (ASU No. 2014-08), which is an update for Accounting Standards Codification Topic No. 205 “Presentation of Financial Statements” and Topic No. 360 “Property, Plant and Equipment’. This update changes the requirements of reporting discontinued operations. Under the amended guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The amendments in this update are effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Although early adoption is permitted, the Company did not elect to apply the guidance of ASU No. 2014-08 to the spin-off of NOW. The adoption of this update concerns presentation and disclosure only as it relates to our consolidated financial statements. The Company expects the impact of ASU No. 2014-08 on its consolidated financial position and results of operations to be immaterial.
	In May 2014, the FASB issued Accounting Standard Update No. 2014-09 “Revenue from Contracts with Customers” (ASU No. 2014-09), which supersedes the revenue recognition requirements in Accounting Standard Codification Topic No. 605 “Revenue Recognition” and most industry-specific guidance. This update requires that entities recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. ASU No. 2014-09 is effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years. The Company is currently assessing the impact of the adoption of ASU No. 2014-09 on its consolidated financial position and results of operations.
