Notes to Financial Statements [Abstract]
1. Summary of Significant Accounting Policies	1.Summary of Significant Accounting Policies GeneralAnadarko Petroleum Corporation is engaged in the exploration, development, production, gathering, processing and marketing of natural gas, crude oil, condensate and natural gas liquids (NGLs). The Company also owns interests in the hard minerals business through its ownership of non-operated joint ventures and royalty arrangements. The terms Anadarko and Company refer to Anadarko Petroleum Corporation and its consolidated subsidiaries. The information, as furnished herein, reflects all normal recurring adjustments that are, in the opinion of management, necessary for the fair presentation of the Companys consolidated financial position as of September30, 2009 and December31, 2008, the consolidated statements of income and comprehensive income for the three and nine months ended September30, 2009 and 2008, cash flows for the nine months ended September30, 2009 and 2008, and the consolidated statement of equity for the nine months ended September30, 2009. Certain amounts for prior periods have been reclassified to conform to the current-period presentation. In preparing financial statements in accordance with accounting principles generally accepted in the United States, management makes informed judgments and estimates that affect both the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Management reviews its estimates periodically, including those related to the carrying value of properties and equipment, proved reserves, goodwill, intangible assets, asset retirement obligations, litigation reserves, environmental liabilities, pension liabilities and costs, income taxes and fair values. Changes in facts and circumstances or additional information may result in revised estimates and actual results may differ from these estimates. The accompanying financial statements and notes should be read in conjunction with the Companys 2008 Annual Report on Form 10-K. Oil and Gas PropertiesThe Company uses the successful efforts method of accounting for oil and gas properties. The Company adopted the successful efforts method of accounting in the third quarter of 2007 and all periods presented reflect application of the successful efforts method of accounting. EarningsPerShareThe Companys basic earnings per share (EPS) amounts have been computed based on the average number of shares of common stock outstanding for the period and include the effect of any participating securities as appropriate. Diluted EPS includes the effect of the Companys outstanding stock options, restricted stock awards, restricted stock units and performance-based stock awards if the inclusion of these items is dilutive. Diluted net loss per share for the nine months ended September30, 2009, does not assume an increase in the average number of shares outstanding from future stock option exercises, unvested restricted stock or similar sources because the inclusion of shares attributable to these sources would have an anti-dilutive effect. See Note 9. Changes in Accounting PrinciplesThe Company adop

This net amount includes a charge of $163 million related to 2007. Management concluded that this misstatement was not material to 2007 interim and annual results, nor to the 2008 period, and corrected the error in the first quarter of 2008.

4. Properties and Equipment	4.PropertiesandEquipment Suspended Exploratory Drilling CostsThe Companys capitalized suspended well costs at September30, 2009 and December31, 2008 were $581 million and $279 million, respectively. The $302 million increase primarily related to drilling in the Gulf of Mexico, Ghana, Brazil and Sierra Leone. For the nine months ended September30, 2009, $41 million of exploratory well costs previously capitalized as suspended well costs for greater than one year were charged to dry hole expense. Also, for the nine months ended September30, 2009, $42 million of capitalized suspended well costs were reclassified to proved properties. Management believes projects with suspended exploratory drilling costs exhibit sufficient quantities of hydrocarbons to justify potential development and is actively pursuing efforts to assess whether reserves can be attributed to these areas. If additional information becomes available that raises substantial doubt as to the economic or operational viability of any of these projects, the associated costs will be expensed at that time.

Notes to Financial Statements [Abstract]
5. Impairments	5.Impairments For the three and nine months ended September30, 2009, the Company recognized impairments of $5 million and $74 million, respectively, related to certain transportation contracts included in intangible assets, due to changes in price differentials at specific locations, and also recognized impairments of zero and $5 million, respectively, related to long-lived assets due to the current economic and commodity price environment. These assets were impaired to fair value. The transportation contract impairments relate to the Marketing segment and the long-lived asset impairments relate to the Oil and Gas Exploration and Production segment. The $74 million impairment of transportation contracts reduced the net book value of these contracts to $8 million. Fair value was determined using a discounted cash flow approach, incorporating market-based inputs. The Company determined that this represented a Level 2 fair value measurement. Amortization expense for transportation contracts for the nine months ended September30, 2009 was $13 million.

6. Investments	6.Investments Noncontrolling Mandatorily Redeemable InterestsIn 2007, Anadarko contributed certain of its oil and gas properties and gathering and processing assets with an aggregate fair value of approximately $2.9 billion at the time of the contribution to newly formed unconsolidated entities in exchange for noncontrolling mandatorily redeemable interests in those entities. Subsequent to their formation, the investee entities loaned Anadarko an aggregate of $2.9 billion. The Company accounts for its investment in these entities under the equity method of accounting. At September30, 2009, the carrying amount of these investments was $2.79 billion, while the carrying amount of notes payable to affiliates was $2.85 billion. Anadarko has legal right of setoff and intends to net settle its obligations under each of the notes payable to the investees with the distributable value of its interest in the corresponding investee. Accordingly, the investments and the obligations are presented net on the consolidated balance sheet with the excess of the notes payable to affiliates over the aggregate investment carrying amount included in other long-term liabilities other for all periods presented. Other income (expense) for the three and nine months ended September30, 2009 includes interest expense on the notes payable to the investee entities of $(12) million and $(48) million, respectively, and equity in earnings from Anadarkos investments in the investee entities of $11 million and $34 million, respectively. Other income (expense) for the three and nine months ended September30, 2008 includes interest expense on the notes payable to the investee entities of $(27) million and $(96) million, respectively, and equity in earnings from Anadarkos investments in the investee entities of $32 million and $106 million, respectively.

Notes to Financial Statements [Abstract]
7. Derivative Instruments	7.Derivative Instruments Objective StrategyThe Company is exposed to commodity price and interest rate risk, and management considers it prudent to periodically reduce the Companys exposure to cash-flow variability resulting from commodity price changes and interest rate fluctuations. Accordingly, the Company enters into certain derivative instruments in order to manage its exposure to these risks. Futures, swaps and options are used to manage the Companys exposure to commodity price risk inherent in the Companys oil and gas production and gas processing operations (Oil and Gas Production/Processing Derivative Activities). Futures contracts and commodity swap agreements are used to fix the price of expected future oil and gas sales at major industry trading locations, such as Henry Hub, Louisiana for gas and Cushing, Oklahoma for oil. Basis swaps are used to fix or float the price differential between the product price at one market location versus another. Options are used to establish a floor and a ceiling price (collar) for expected future oil and gas sales. Derivative instruments are also used to manage commodity price risk inherent in customer pricing requirements and to fix margins on the future sale of natural gas and NGLs from the Companys leased storage facilities (Marketing and Trading Derivative Activities). The Company may also enter into physical-delivery sales contracts to manage cash-flow variability. These contracts call for the receipt or delivery of physical product at a specified location and price, which may be fixed or market-based. Interest rate swaps are used to fix or float interest rates on existing or anticipated indebtedness. The purpose of these instruments is to mitigate the Companys existing or anticipated exposure to unfavorable interest rate changes. The Company does not apply hedge accounting to any of its derivative instruments. The application of hedge accounting was discontinued by the Company for periods beginning on or after January1, 2007. As a result, both realized and unrealized gains and losses associated with derivative instruments are recognized in earnings. Net derivative losses attributable to derivatives previously subject to hedge accounting and residing in accumulated other comprehensive income (loss) are reclassified to earnings in future periods as the economic transactions to which the derivatives relate are recorded in earnings. The accumulated other comprehensive loss balances related to commodity derivatives at September30, 2009 and December31, 2008, were $13 million ($8 million after tax) and $22 million ($14 million after tax), respectively. The accumulated other comprehensive loss balances related to interest rate derivatives at September30, 2009 and December31, 2008, were $145 million ($93 million after tax) and $163 million ($104 million after tax), respectively.

For the nine months ended September30, 2009, basic EPS was not impacted by the two-class method because the Companys participating securities are not obligated to share in the losses of the Company, and diluted EPS was not impacted because the inclusion of these securities would have had an anti-dilutive effect on diluted EPS. For both the three and nine months ended September30, 2008, basic and diluted EPS, as previously reported, decreased $0.06 and $0.04, respectively, under the two-class method. For the three and nine months ended September30, 2009, awards for 5.8million and 14.1million average shares, respectively, of common stock were excluded from the diluted EPS calculation because the inclusion of these shares would have had an anti-dilutive effect. For the three and nine months ended September30, 2008, awards for 6.8million and 6.9million average shares, respectively, of common stock were excluded from the diluted EPS calculation because the inclusion of these shares would have had an anti-dilutive effect. In May 2009, Anadarko completed a public offering of 30million shares of common stock at $45.50 per share. After deducting the underwriting discount and other offering costs of $28 million, net proceeds to the Company were approximately $1.3 billion. Net proceeds from the offering are to be used for general corporate purposes, including capital expenditures. For all periods presented, quarterly dividends of nine cents per share were paid to holders of common stock. As of September30, 2009, the covenants contained in certain of the Companys credit an

10. Commitments and Contingencies	10.Commitments and Contingencies GeneralLitigation charges and adjustments of $1 million and $46 million decreased income from continuing operations before income taxes for the three and nine months ended September30, 2009, respectively. Litigation charges and adjustments of $103 million and $109 million decreased income from continuing operations before income taxes for the three and nine months ended September30, 2008, respectively. The Company is a defendant in a number of lawsuits and is involved in government proceedings, including, but not limited to, royalty claims, contract claims and environmental claims. The Company has also been named as a defendant in various personal injury claims, including claims by employees of third-party contractors alleging exposure to asbestos, silica and benzene while working at refineries (previously owned by predecessors of acquired companies) located in Texas, California and Oklahoma. While the ultimate outcome and impact on the Company cannot be predicted with certainty, management believes that the resolution of these proceedings will not have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company. LitigationThe Company is subject to various claims from its royalty owners in the regular course of business as an oil and gas producer, including disputes regarding measurement, costs and expenses beyond the wellhead and basis for royalty valuations. The Company was named as a defendant in a case styled U.S. of America ex rel. Harold E. Wright v. AGIP Company, et al. filed in September 2000 in the U.S. District Court for the Eastern District of Texas, Lufkin Division. Kerr-McGee Corporation (Kerr-McGee) was also named as a defendant in this legal proceeding. This lawsuit generally alleges that the Company, including Kerr-McGee, and 117 other defendants undervalued natural gas in connection with royalty payments on production from federal and Indian lands. Based on the Companys present understanding of these various governmental and False Claims Act proceedings, the Company believes that it has substantial defenses to these claims and intends to vigorously assert such defenses. However, if the Company is found to have violated the False Claims Act, the Company could be subject to a variety of sanctions, including treble damages and substantial monetary fines. The discovery process is ongoing. The court has entered an order whereby the case will be tried in phases. The claims against the Company have yet to be set for trial. Prior to its acquisition by Anadarko, Kerr-McGee reached a settlement with the government; however, the court permitted Mr.Wright to conduct additional discovery to test the reasonableness of the settlement. The Company believes that any additional loss is unlikely to have a material adverse effect on Anadarkos consolidated financial position, results of operations or cash flows. Deepwater Royalty Relief ActIn 1995, the United States Congress passed the Deepwater Royalty Relief Act (DWRRA) to stimulate exploration and production of oil and natural gas by providing relief from the obligation to pay royalties on cert

The variance from the 35% statutory rate for the nine months ended September30, 2009 is primarily attributable to the accrual of the Algerian exceptional profits tax, other foreign taxes in excess of the federal statutory rate, U.S. residual income tax on foreign income, partially offset by benefits associated with changes in uncertain tax positions, state income taxes, including a change in the state income tax rate expected to be in effect at the time the Companys deferred state income tax liability is expected to be settled or realized, and U.S. income tax benefits from investments in foreign stock and other items. The variance from the 35% statutory rate for the three months ended September30, 2008 is primarily attributable to the accrual of the Algerian exceptional profits tax, other foreign taxes in excess of the federal statutory rate, state income taxes and other items. The variance from the 35% statutory rate for the nine months ended September30, 2008 also includes the recognition of tax expense on the Companys subsequent divestiture in December 2008 of its 50% interest in the Peregrino field offshore Brazil in advance of the recognition of the associated gain on sale and the tax effect of the prior-period book income correction recorded in the first quarter of 2008.

Notes to Financial Statements [Abstract]
13. Segment Information	13.Segment Information Anadarkos primary business segments are vertically integrated within the oil and gas industry. These segments are separately managed because of the nature of their products and services, as well as unique technology, distribution and marketing requirements. The Companys three operating segments are oil and gas exploration and production, midstream, and marketing. The exploration and production segment explores for and produces natural gas, crude oil, condensate and NGLs. The midstream segment engages in gathering, processing, treating and transporting Anadarkos and third-party oil and gas production. The marketing segment sells most of Anadarkos production, as well as production purchased. To assess the operating results of Anadarkos segments, management analyzes income from continuing operations before income taxes, interest expense, exploration expense, depreciation, depletion and amortization (DDA) expense and impairments, less net income attributable to noncontrolling interests (Adjusted EBITDAX). Anadarkos definition of Adjusted EBITDAX excludes exploration expense, as exploration expense is not an indicator of operating efficiency for a given reporting period, but is monitored by management as part of costs incurred in exploration and development activities. Similarly, DDA expense and impairments are excluded from Adjusted EBITDAX as a measure of segment operating performance, because capital expenditures are evaluated at the time capital costs are incurred. The Companys definition of Adjusted EBITDAX also excludes interest expense to allow for assessment of segment operating results without regard to Anadarkos financing methods or capital structure. Management believes that the presentation of Adjusted EBITDAX provides information useful in assessing the Companys financial condition and results of operations and that Adjusted EBITDAX is a widely accepted financial indicator of a companys ability to incur and service debt, fund capital expenditures and make distributions to stockholders. Adjusted EBITDAX may not be comparable to similarly titled measures used by other companies. Therefore, Anadarkos consolidated Adjusted EBITDAX should be considered in conjunction with income (loss) from continuing operations attributable to common stockholders and other performance measures, such as operating income or cash flow from operating activities. Below is a reconciliation of consolidated Adjusted EBITDAX to income (loss) from continuing operations before income taxes.

During the nine months ended September30, 2009, the Company made contributions of $133 million to its funded pension plans, $17 million to its unfunded pension plans and $14 million to its unfunded other postretirement benefit plans. Contributions to funded plans increase plan assets while contributions to unfunded plans are used to fund current benefit payments. During the remainder of 2009, the Company expects to contribute approximately $14 million to its funded pension plans, approximately $6 million to its unfunded pension plans and approximately $8 million to its unfunded other postretirement benefit plans. The following table sets forth the Companys pension and other postretirement benefit costs.
