Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company’s financial statements for prior periods include reclassifications that were made to conform to the current-period presentation. During the second quarter of 2015, Apache completed the sale of its Australian LNG business and oil and gas assets. Results of operations and consolidated cash flows for the divested Australia assets are reflected as discontinued operations in the Company’s financial statements for all periods presented. For more information regarding these divestitures, please refer to Note 3—Acquisitions and Divestitures. Recast Financial Information for Change in Accounting Principle In the second quarter of 2016, Apache voluntarily changed its method of accounting for its oil and gas exploration and development activities from the full cost method to the successful efforts method of accounting. The financial information for prior periods has been recast to reflect retrospective application of the successful efforts method, as prescribed by the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 932 “Extractive Activities—Oil and Gas.” Although the full cost method of accounting for oil and gas exploration and development activities continues to be an accepted alternative, the successful efforts method of accounting is the generally preferred method of the U.S. Securities and Exchange Commission (SEC) and is more widely used in the industry such that the change will improve comparability of the Company's financial statements to its peers. The Company believes the successful efforts method provides a more representational depiction of assets and operating results. The successful efforts method also provides for the Company's investments in oil and gas properties to be assessed for impairment in accordance with ASC 360 "Property, Plant, and Equipment" rather than valuations based on prices and costs prescribed under the full cost method as of the balance sheet date. For more detailed information regarding the effects of the change to the successful efforts method, please refer to Note 2—Change in Accounting Principle. The Company has recast certain historical information for all periods presented, including the Statement of Consolidated Operations, Statement of Consolidated Cash Flows, Consolidated Balance Sheet, Statement of Consolidated Changes in Equity, and related information in Notes 1, 2, 3, 4, 5, 7, 8, 10, 11, and 12. In the first quarter of 2016 , the Company retrospectively adopted a new accounting standard update ASU 2015-03 "Simplifying the Presentation of Debt Issuance Costs," which requires debt issuance costs to be presented as a direct deduction from the carrying value of the associated debt liability, consistent with debt discounts. For more information regarding this update, please refer to Note 7—Debt and Financing Costs. As of June 30, 2016 , Apache’s significant accounting policies, other than those discussed above, are consistent with those discussed in Note 1—Summary of Significant Accounting Policies to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates with regard to these financial statements include the fair value determination of acquired assets and liabilities, the estimate of proved oil and gas reserves and related present value estimates of future net cash flows therefrom, the assessment of asset retirement obligations, the estimates of fair value for long-lived assets and goodwill, and the estimate of income taxes. Actual results could differ from those estimates. Fair Value Measurements Certain assets and liabilities are reported at fair value on a recurring basis in Apache’s consolidated balance sheet. ASC 820-10-35 provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority. The valuation techniques that may be used to measure fair value include a market approach, an income approach, and a cost approach. A market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. An income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectations, including present value techniques, option-pricing models, and the excess earnings method. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Apache also uses fair value measurements on a nonrecurring basis when certain qualitative assessments of its assets indicate a potential impairment. For the six-month period ended June 30, 2016, the Company recorded asset impairments totaling $281 million in connection with fair value assessments in the current low commodity price environment. Impairments totaling $176 million were recorded for oil and gas properties in the U.S. and Canada and $105 million was recorded for GTP assets, which were written down to their fair values. The oil and gas property impairments are discussed in further detail below in “Oil and Gas Property.” For the six-month period ended June 30, 2015, the Company recorded asset impairments totaling $2.7 billion in connection with fair value assessments in the current low commodity price environment. Impairments totaling $2.6 billion were recorded for oil and gas properties, which were written down to their fair values. Also, for the six-month period ended June 30, 2015, the Company recorded $163 million for the impairment of goodwill. As of June 30, 2016 and December 31, 2015, remaining goodwill in the consolidated balance sheet totaled $87 million for our Egypt reporting unit. Oil and Gas Property The Company follows the successful efforts method of accounting for its oil and gas property. Under this method of accounting, exploration costs such as exploratory dry holes, exploratory geological and geophysical costs, delay rentals, unproved impairments, and exploration overhead are expensed as incurred. All costs related to production, general corporate overhead, and similar activities are expensed as incurred. If an exploratory well provides evidence to justify potential development of reserves, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations. At the end of each quarter, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities; in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed. Acquisition costs of unproved properties are assessed for impairment at least annually and are transferred to proved oil and gas properties to the extent the costs are associated with successful exploration activities. Significant undeveloped leases are assessed individually for impairment based on the Company’s current exploration plans. Unproved oil and gas properties with individually insignificant lease acquisition costs are amortized on a group basis over the average lease term at rates that provide for full amortization of unsuccessful leases upon lease expiration or abandonment. Costs of expired or abandoned leases are charged to exploration expense, while costs of productive leases are transferred to proved oil and gas properties. Costs of maintaining and retaining unproved properties, as well as amortization of individually insignificant leases and impairment of unsuccessful leases, are included in exploration costs in the statement of consolidated operations. Costs to develop proved reserves, including the costs of all development wells and related equipment used in the production of crude oil and natural gas, are capitalized. Depreciation of the cost of proved oil and gas properties is calculated using the unit-of-production (UOP) method. The UOP calculation multiplies the percentage of estimated proved reserves produced each quarter by the cost of those reserves. The reserve base used to calculate depreciation for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. With respect to lease and well equipment costs, which include development costs and successful exploration drilling costs, the reserve base includes only proved developed reserves. Estimated future dismantlement, restoration and abandonment costs, net of salvage values, are included in the depreciable cost. Oil and gas properties are grouped for depreciation in accordance with ASC 932 “Extractive Activities - Oil and Gas.” The basis for grouping is a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field. When circumstances indicate that proved oil and gas properties may be impaired, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets grouped at the lowest level for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows, based on Apache’s estimate of future crude oil and natural gas prices, operating costs, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally estimated using the income approach described in the ASC 820 “Fair Value Measurement.” If applicable, the Company utilizes accepted bids as the basis for determining fair value. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments of future production volumes, commodity prices, operating costs, and capital investment plans, considering all available information at the date of review. These assumptions are applied to develop future cash flow projections that are then discounted to estimated fair value, using a discount rate believed to be consistent with those applied by market participants. Apache has classified these fair value measurements as Level 3 in the fair value hierarchy. The following table represents non-cash impairments of the carrying value of the Company’s proved and unproved property and equipment for the second quarters and first six months of 2016 and 2015 : Quarter Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 (In millions) Oil and Gas Property: Proved $ 68 $ 349 $ 68 $ 2,261 Unproved 66 148 108 316 Proved properties impaired during the quarter ended June 30, 2016 had an aggregate fair value of $143 million . Proved properties impaired during the quarter ended March 31, 2015 had an aggregate fair value of $1.2 billion , and properties impaired during the quarter ended June 30, 2015 had an aggregate fair value of $516 million . On the statement of consolidated operations, unproved impairments are recorded in exploration expense, and proved impairments are recorded in impairments. Gains and losses on significant divestitures are recognized in the statement of consolidated operations. See Note 3—Acquisitions and Divestitures for more detail. New Pronouncements Issued But Not Yet Adopted In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, which seeks to simplify accounting for share-based payment transactions including income tax consequences, classification of awards as either equity or liabilities, and the classification on the statement of cash flows. The new standard requires the Company to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The guidance is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted and if an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, a new lease standard requiring lessees to recognize lease assets and lease liabilities for most leases classified as operating leases under previous U.S. GAAP. The guidance is effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The Company will be required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In May 2014, the FASB and the International Accounting Standards Board (IASB) issued a joint revenue recognition standard, ASU 2014-09. The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued ASU 2016-08, which provides further clarification on the principal versus agent evaluation. The guidance is effective for annual and interim periods beginning after December 15, 2017. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Company is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.

Accounting Changes and Error Corrections [Abstract]
Change in Accounting Principle	CHANGE IN ACCOUNTING PRINCIPLE During the second quarter of 2016, the Company voluntarily changed its method of accounting for oil and gas exploration and development activities from the full cost method to the successful efforts method. Accordingly, financial information for prior periods has been recast to reflect retrospective application of the successful efforts method. In general, under successful efforts, exploration expenditures such as exploratory dry holes, exploratory geological and geophysical costs, delay rentals, unproved impairments, and exploration overhead are charged against earnings as incurred, versus being capitalized under the full cost method of accounting. Successful efforts also provides for the assessment of potential property impairments under ASC 360 by comparing the net carrying value of oil and gas properties with associated projected undiscounted pre-tax future net cash flows. If the expected undiscounted pre-tax future net cash flows are lower than the unamortized capitalized costs, the capitalized cost is reduced to fair value. Under the full cost method of accounting, a write-down would be required if the net carrying value of oil and gas properties exceeds a full cost “ceiling,” using an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months. In addition, gains or losses, if applicable, are generally recognized on the dispositions of oil and gas property and equipment under the successful efforts method, as opposed to an adjustment to the net carrying value of the remaining assets under the full cost method. Apache’s consolidated financial statements have been recast to reflect these differences. The following tables present the effects of the change to the successful efforts method in the statement of consolidated operations: Changes to the Statement of Consolidated Operations For the Quarter

Extractive Industries [Abstract]
Capitalized Exploratory Well Costs	CAPITALIZED EXPLORATORY WELL COSTS The Company’s capitalized exploratory well costs were $262 million and $245 million at June 30, 2016 and December 31, 2015 , respectively. The increase is primarily attributable to drilling activities, partially offset by successful transfers and dry hole write-offs. Exploratory well costs that have been capitalized for a period greater than one year since the completion of drilling were $93 million and $61 million at June 30, 2016 and December 31, 2015, respectively. The exploratory well costs that had been capitalized for a period greater than one year at December 31, 2015 are associated with the Aviat discovery in the North Sea and comprise exploration and appraisal activities. The amount of exploratory well costs capitalized for a period greater than one year increased by $32 million during the six months ended June 30, 2016 as a result of exploration drilling in Suriname. No suspended exploratory well costs previously capitalized for greater than one year at December 31, 2015 were charged to dry hole expense during the six months ended June 30, 2016. Projects with suspended exploratory well costs capitalized for a period greater than one year since the completion of drilling are those identified by management as exhibiting sufficient quantities of hydrocarbons to justify potential development. Management is actively pursuing efforts to assess whether reserves can be attributed to these projects.

Debt and Financing Costs	DEBT AND FINANCING COSTS The following table presents the carrying amounts and estimated fair values of the Company’s outstanding debt as of June 30, 2016 and December 31, 2015 : June 30, 2016 December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Commercial paper and committed bank facilities $ — $ — $ — $ — Notes and debentures 8,720 9,393 8,717 8,330 Total Debt $ 8,720 $ 9,393 $ 8,717 $ 8,330 The Company’s debt is recorded at the carrying amount, net of related unamortized discount and debt issuance costs, on its consolidated balance sheet. The carrying amount of the Company’s commercial paper, committed bank facilities, and uncommitted bank lines approximates fair value because the interest rates are variable and reflective of market rates. Apache uses a market approach to determine the fair value of its notes and debentures using estimates provided by an independent investment financial data services firm (a Level 2 fair value measurement). As of June 30, 2016 , the Company had a $3.5 billion five -year revolving credit facility which matures in June 2020 . Proceeds from borrowings may be used for general corporate purposes. Apache’s available borrowing capacity under this facility supports its $3.5 billion commercial paper program. The commercial paper program, which is subject to market availability, facilitates Apache borrowing funds for up to 270 days at competitive interest rates. As of June 30, 2016 , the Company had no debt outstanding under commercial paper, committed bank facilities, and uncommitted bank lines. As of June 30, 2016 , the Company had a £900 million three -year letter of credit facility which matures in February 2019. The facility is available for letters of credit and loans to cash collateralize letter of credit obligations to the extent letters of credit are unavailable under the facility. As of June 30, 2016, no letters of credit or loans were outstanding under this facility. Subsequently, as of the date of this filing, a letter of credit for approximately £96 million was outstanding under this facility. In April 2015, the FASB issued ASU 2015-03 "Simplifying the Presentation of Debt Issuance Costs," which requires debt issuance costs to be presented as a direct deduction from the carrying value of the associated debt liability. The Company adopted this update in the first quarter of 2016 and applied the changes retrospectively for all periods presented. At December 31, 2015 , the Company had debt issuance costs of $61 million classified as a long-term asset as a component of "deferred charges and other" on the balance sheet that have been netted against "long-term debt" in these unaudited interim financial statements. As of June 30, 2016 , long-term debt is presented net of debt issuance costs of $58 million .

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company estimates its annual effective income tax rate for continuing operations in recording its quarterly provision for income taxes in the various jurisdictions in which the Company operates. Non-cash write-downs of the carrying value of the Company’s proved oil and gas properties, statutory tax rate changes, and other significant or unusual items are recognized as discrete items in the quarter in which they occur. During the second quarter of 2016, Apache’s effective income tax rate was primarily impacted by an increase in the valuation allowance on Canadian deferred tax assets. During the second quarter of 2015, Apache’s effective tax rate was primarily impacted by non-cash impairments of the carrying value of the Company's proved oil and gas properties and an increase in the amount of valuation allowances on Canadian deferred tax assets and U.S. foreign tax credits. Apache's 2016 year-to-date effective tax rate is primarily impacted by an increase in the valuation allowance on Canadian deferred tax assets. Apache's 2015 year-to-date effective tax rate was primarily impacted by non-cash impairments of the carrying value of the Company's proved oil and gas properties and an increase in the amount of valuation allowances on Canadian deferred tax assets and U.S. foreign tax credits, offset by a $414 million deferred tax benefit associated with a reduction in the U.K. statutory income tax rate from 62 percent to 50 percent .

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Matters Apache is party to various legal actions arising in the ordinary course of business, including litigation and governmental and regulatory controls. As of June 30, 2016 , the Company has an accrued liability of approximately $30 million for all legal contingencies that are deemed to be probable of occurring and can be reasonably estimated. Apache’s estimates are based on information known about the matters and its experience in contesting, litigating, and settling similar matters. Although actual amounts could differ from management’s estimate, none of the actions are believed by management to involve future amounts that would be material to Apache’s financial position, results of operations, or liquidity after consideration of recorded accruals. For material matters that Apache believes an unfavorable outcome is reasonably possible, the Company has disclosed the nature of the matter and a range of potential exposure, unless an estimate cannot be made at this time. It is management’s opinion that the loss for any other litigation matters and claims that are reasonably possible to occur will not have a material adverse effect on the Company’s financial position, results of operations, or liquidity. For additional information on each of the Legal Matters described below, please see Note 9—Commitments and Contingencies to the consolidated financial statements contained in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Argentine Environmental Claims and Argentina Tariff No material change in the status of the YPF Sociedad Anónima and Pioneer Natural Resources Company indemnities matters has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Louisiana Restoration As more fully described in Apache’s Annual Report on Form 10-K for its 2015 fiscal year, numerous surface owners have filed claims or sent demand letters to various oil and gas companies, including Apache, claiming that, under either express or implied lease terms or Louisiana law, the companies are liable for damage measured by the cost of restoration of leased premises to their original condition as well as damages for contamination and cleanup. On or about July 28, 2016, in a case captioned Keith Stutes, District Attorney for the 15th Judicial District of the State of Louisiana v. Gulfport Energy Corporation et al. , Docket No. 102156, in the 15th Judicial District Court, Parish of Vermilion, State of Louisiana, plaintiff asserts coastal zone claims similar to the claims filed previously by Plaquemines Parish and Cameron Parish against Apache and various other oil and gas producers. In respect of three lawsuits filed by the Parish of Plaquemines against the Company and other oil and gas producers in the 25 th Judicial District Court for the Parish of Plaquemines, State of Louisiana (captioned Parish of Plaquemines v. Rozel Operating Company et al., Docket No. 60-996; Parish of Plaquemines v. Apache Oil Corporation et al., Docket No. 61-000; and Parish of Plaquemines v. HHE Energy Company et al., Docket No. 60-983), in April 2016 the Plaquemines Parish Council reversed course and decided not to dismiss the lawsuits. The Louisiana Attorney General has announced his intention to intervene in the three Plaquemines Parish proceedings and in the Cameron Parish proceedings in the Parish’s 38 th Judicial District Court, captioned Parish of Cameron v. BEPCO, L.P., et al. , Docket No. 10-19572; Parish of Cameron v. BP America Production Company et al. , Docket No. 10-19576; Parish of Cameron v.

The Cameron Parish proceedings have been removed to the United States District Court for the Western District of Louisiana, subject to any effort by plaintiff to remand the proceedings to state court. No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Apollo Exploration Lawsuit In a fourth amended petition filed on March 21, 2016, in a case captioned Apollo Exploration, LLC, Cogent Exploration, Ltd. Co. & SellmoCo, LLC v. Apache Corporation , Cause No. CV50538 in the 385 th Judicial District Court, Midland County, Texas, plaintiffs have reduced their alleged damages to approximately $500 million (having previously claimed in excess of $1.1 billion ) relating to certain purchase and sale agreements, mineral leases, and areas of mutual interest agreements concerning properties located in Hartley, Moore, Potter, and Oldham Counties, Texas. Apache believes that plaintiffs’ claims lack merit, and further that plaintiffs’ alleged damages, even as amended, are grossly inflated. Apache will vigorously oppose the claims. No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Escheat Audits There has been no other material change with respect to the review of the books and records of the Company and its subsidiaries and related entities by the State of Delaware, Department of Finance (Unclaimed Property), to determine compliance with the Delaware Escheat Laws, since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 .

Australia and New Zealand Banking Group Limited (ANZ) et al. , No. SCI 2012 01995, in the Supreme Court of Victoria, trial commenced on May 30, 2016, and is ongoing. Apache Corporation, Apache Energy Limited (now known as Quadrant Energy Australia Limited), and Apache Northwest Pty Ltd (now known as Quadrant Northwest Pty Ltd) have, subject to certain conditions precedent, reached a settlement on confidential terms with each of the plaintiffs and related entities. No other material change in the status of this matter has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Environmental Matters As of June 30, 2016 , the Company had an undiscounted reserve for environmental remediation of approximately $57 million . The Company is not aware of any environmental claims existing as of June 30, 2016 , that have not been provided for or would otherwise have a material impact on its financial position, results of operations, or liquidity. There can be no assurance, however, that current regulatory requirements will not change or past non-compliance with environmental laws will not be discovered on the Company’s properties. Apache Canada Ltd. (ACL) reported a produced water release from a water injection pipeline in a remote area of the Belloy Field that occurred on or about May 4, 2016. The cause of the release remains under investigation. With respect to this release, the summons and information containing charges relating to a leak of produced water in the Zama area that occurred on or between October 3 and October 25, 2013, and the summons and information containing charges relating to a leak of produced water in the Belloy Field operating area that occurred on or about January 20, 2014, the Company does not expect the economic impact of these incidents to have a material effect on the Company’s financial position, results of operations, or liquidity. No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Australian Operations Divestiture Dispute By a Sale and Purchase Agreement dated April 9, 2015 (“SPA”), the Company and its subsidiaries divested their remaining Australian operations to Viraciti Energy Pty Ltd, which has since been renamed Quadrant Energy Pty Ltd (“Quadrant”). Closing occurred on June 5, 2015. By letter dated June 6, 2016, Quadrant provided the Company with a one -year placeholder notice of claim under the SPA concerning tax and other issues totaling approximately $200 million in the aggregate. The Company is in the process of reviewing the issues raised by Quadrant and believes at this time that these matters will not have a material adverse effect on the Company’s financial position, results of operation, or liquidity. LNG Divestiture Dispute In respect of the purchase by Woodside of the Wheatstone and Kitimat LNG projects and accompanying upstream oil and gas reserves from the Company and its subsidiaries, several court proceedings are pending in the Supreme Court of Western Australia (Case Nos. 2315 of 2015, 2798 of 2015, 1504 of 2016, 1520 of 2016, and 1521 of 2016) concerning or arising out of the Wheatstone sale and purchase agreement, including whether certain amounts are due and owing Apache from Woodside and whether certain of Woodside’s purchase price adjustment claims are time-barred. In addition, Woodside is attempting to commence third party expert determination proceedings at the ICC International Centre for ADR in respect of certain aspects of its purchase price adjustment claims. The Company believes that under the terms of the sale and purchase agreements, Woodside’s requests for payment of purchase price adjustments lack merit and further that Woodside must reimburse Apache certain costs relating to Wheatstone and Kitimat; therefore, the Company has not recorded a liability associated with this dispute. No other material change in the status of these matters has occurred since the filing of Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 .

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates with regard to these financial statements include the fair value determination of acquired assets and liabilities, the estimate of proved oil and gas reserves and related present value estimates of future net cash flows therefrom, the assessment of asset retirement obligations, the estimates of fair value for long-lived assets and goodwill, and the estimate of income taxes. Actual results could differ from those estimates.
Fair Value Measurements	Fair Value Measurements Certain assets and liabilities are reported at fair value on a recurring basis in Apache’s consolidated balance sheet. ASC 820-10-35 provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consist of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority. The valuation techniques that may be used to measure fair value include a market approach, an income approach, and a cost approach. A market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. An income approach uses valuation techniques to convert future amounts to a single present amount based on current market expectations, including present value techniques, option-pricing models, and the excess earnings method. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Apache also uses fair value measurements on a nonrecurring basis when certain qualitative assessments of its assets indicate a potential impairment. For the six-month period ended June 30, 2016, the Company recorded asset impairments totaling $281 million in connection with fair value assessments in the current low commodity price environment. Impairments totaling $176 million were recorded for oil and gas properties in the U.S. and Canada and $105 million was recorded for GTP assets, which were written down to their fair values. The oil and gas property impairments are discussed in further detail below in “Oil and Gas Property.” For the six-month period ended June 30, 2015, the Company recorded asset impairments totaling $2.7 billion in connection with fair value assessments in the current low commodity price environment. Impairments totaling $2.6 billion were recorded for oil and gas properties, which were written down to their fair values. Also, for the six-month period ended June 30, 2015, the Company recorded $163 million for the impairment of goodwill. As of June 30, 2016 and December 31, 2015, remaining goodwill in the consolidated balance sheet totaled $87 million for our Egypt reporting unit.
Oil and Gas Property	Oil and Gas Property The Company follows the successful efforts method of accounting for its oil and gas property. Under this method of accounting, exploration costs such as exploratory dry holes, exploratory geological and geophysical costs, delay rentals, unproved impairments, and exploration overhead are expensed as incurred. All costs related to production, general corporate overhead, and similar activities are expensed as incurred. If an exploratory well provides evidence to justify potential development of reserves, drilling costs associated with the well are initially capitalized, or suspended, pending a determination as to whether a commercially sufficient quantity of proved reserves can be attributed to the area as a result of drilling. This determination may take longer than one year in certain areas depending on, among other things, the amount of hydrocarbons discovered, the outcome of planned geological and engineering studies, the need for additional appraisal drilling activities to determine whether the discovery is sufficient to support an economic development plan, and government sanctioning of development activities in certain international locations. At the end of each quarter, management reviews the status of all suspended exploratory well costs in light of ongoing exploration activities; in particular, whether the Company is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed. Acquisition costs of unproved properties are assessed for impairment at least annually and are transferred to proved oil and gas properties to the extent the costs are associated with successful exploration activities. Significant undeveloped leases are assessed individually for impairment based on the Company’s current exploration plans. Unproved oil and gas properties with individually insignificant lease acquisition costs are amortized on a group basis over the average lease term at rates that provide for full amortization of unsuccessful leases upon lease expiration or abandonment. Costs of expired or abandoned leases are charged to exploration expense, while costs of productive leases are transferred to proved oil and gas properties. Costs of maintaining and retaining unproved properties, as well as amortization of individually insignificant leases and impairment of unsuccessful leases, are included in exploration costs in the statement of consolidated operations. Costs to develop proved reserves, including the costs of all development wells and related equipment used in the production of crude oil and natural gas, are capitalized. Depreciation of the cost of proved oil and gas properties is calculated using the unit-of-production (UOP) method. The UOP calculation multiplies the percentage of estimated proved reserves produced each quarter by the cost of those reserves. The reserve base used to calculate depreciation for leasehold acquisition costs and the cost to acquire proved properties is the sum of proved developed reserves and proved undeveloped reserves. With respect to lease and well equipment costs, which include development costs and successful exploration drilling costs, the reserve base includes only proved developed reserves. Estimated future dismantlement, restoration and abandonment costs, net of salvage values, are included in the depreciable cost. Oil and gas properties are grouped for depreciation in accordance with ASC 932 “Extractive Activities - Oil and Gas.” The basis for grouping is a reasonable aggregation of properties with a common geological structural feature or stratigraphic condition, such as a reservoir or field. When circumstances indicate that proved oil and gas properties may be impaired, the Company compares unamortized capitalized costs to the expected undiscounted pre-tax future cash flows for the associated assets grouped at the lowest level for which identifiable cash flows are independent of cash flows of other assets. If the expected undiscounted pre-tax future cash flows, based on Apache’s estimate of future crude oil and natural gas prices, operating costs, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally estimated using the income approach described in the ASC 820 “Fair Value Measurement.” If applicable, the Company utilizes accepted bids as the basis for determining fair value. The expected future cash flows used for impairment reviews and related fair value calculations are typically based on judgmental assessments of future production volumes, commodity prices, operating costs, and capital investment plans, considering all available information at the date of review. These assumptions are applied to develop future cash flow projections that are then discounted to estimated fair value, using a discount rate believed to be consistent with those applied by market participants. Apache has classified these fair value measurements as Level 3 in the fair value hierarchy. The following table represents non-cash impairments of the carrying value of the Company’s proved and unproved property and equipment for the second quarters and first six months of 2016 and 2015 : Quarter Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 (In millions) Oil and Gas Property: Proved $ 68 $ 349 $ 68 $ 2,261 Unproved 66 148 108 316 Proved properties impaired during the quarter ended June 30, 2016 had an aggregate fair value of $143 million . Proved properties impaired during the quarter ended March 31, 2015 had an aggregate fair value of $1.2 billion , and properties impaired during the quarter ended June 30, 2015 had an aggregate fair value of $516 million . On the statement of consolidated operations, unproved impairments are recorded in exploration expense, and proved impairments are recorded in impairments. Gains and losses on significant divestitures are recognized in the statement of consolidated operations. See Note 3—Acquisitions and Divestitures for more detail.
New Pronouncements Issued But Not Yet Adopted	New Pronouncements Issued But Not Yet Adopted In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, which seeks to simplify accounting for share-based payment transactions including income tax consequences, classification of awards as either equity or liabilities, and the classification on the statement of cash flows. The new standard requires the Company to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The guidance is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted and if an entity early adopts the guidance in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, a new lease standard requiring lessees to recognize lease assets and lease liabilities for most leases classified as operating leases under previous U.S. GAAP. The guidance is effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The Company will be required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. In May 2014, the FASB and the International Accounting Standards Board (IASB) issued a joint revenue recognition standard, ASU 2014-09. The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued ASU 2016-08, which provides further clarification on the principal versus agent evaluation. The guidance is effective for annual and interim periods beginning after December 15, 2017. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Company is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.
