Organization And Nature Of Operations | Organization and Nature of Operations Pioneer Natural Resources Company ("Pioneer" or the "Company") is a Delaware corporation whose common stock is listed and traded on the New York Stock Exchange. The Company is a large independent oil and gas exploration and production company that explores for, develops and produces oil, natural gas liquids ("NGLs") and gas within the United States, with operations primarily in the Permian Basin in West Texas, the Eagle Ford Shale play in South Texas, the Raton Basin field in southeast Colorado and the West Panhandle field in the Texas Panhandle. In February 2018, the Company announced its intention to divest its properties in the South Texas, Raton and West Panhandle fields and focus its efforts and capital resources on its Permian Basin assets. Thus far into 2018, the Company has accomplished the following: • In April 2018, the Company completed the sale of approximately 10,200 net acres in the western portion of the Eagle Ford Shale ("West Eagle Ford Shale") to an unaffiliated third party for cash proceeds of $103 million , before normal closing adjustments. • In June 2018, the Company entered into a purchase and sale agreement with an unaffiliated third party to sell all of its assets in the Raton Basin for cash proceeds of $79 million , before normal closing adjustments. The sale closed in July 2018. • In July 2018, the Company announced it signed a purchase and sale agreement to sell its assets in the West Panhandle field to an unaffiliated third party for cash proceeds of $201 million , before normal closing adjustments. See Note 3 for further information regarding the sale of the Company's West Eagle Ford Shale and Raton Basin assets and Note 16 for further information regarding the Company's sale of its West Panhandle field assets. No assurance can be given that the remaining planned asset divestitures will be completed in accordance with the Company's plan or on terms and at prices acceptable to the Company. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation Presentation. In the opinion of management, the consolidated financial statements of the Company as of June 30, 2018 and for the three and six months ended June 30, 2018 and 2017 include all adjustments and accruals, consisting only of normal, recurring accrual adjustments, which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed in or omitted from this report pursuant to the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). These consolidated financial statements should be read together with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . Certain reclassifications have been made to the 2017 financial statement and footnote amounts in order to conform to the 2018 presentation. Assets held for sale. On the date at which the Company meets all the held for sale criteria, the Company discontinues the recording of depletion and depreciation of the assets or asset group to be sold and reclassifies the assets and related liabilities to be sold as held for sale in the accompanying consolidated balance sheets. The assets and liabilities are measured at the lower of their carrying amount or estimated fair value less cost to sell. See Note 3 for additional information about the Company's divestitures. Accounting policy changes. During the second quarter of 2018, the Company made a voluntary change in accounting policy to account for its materials and supplies inventory on a weighted average cost basis, versus using the previous accounting policy of the first-in-first-out (“FIFO”) basis. The Company made this voluntary change in accounting policy because it believes this method is preferable, as the weighted average cost basis more closely aligns with the physical flow of material and supplies inventory and is more widely utilized in the oil and gas industry. This voluntary change in accounting policy did not have a material effect on the Company’s consolidated financial statements for prior periods or for the current period. As such, prior periods have not been restated. Adoption of new accounting standards. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 ("ASC 606"), "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition” ("ASC 605"), and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. See Note 11 for a discussion of the impact to the Company's recognition of revenue associated with the adoption of ASC 606. In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as certain classification changes in the statement of cash flows. The Company adopted this standard on January 1, 2017. See Note 14 for a discussion of the impact to the Company's income tax provision associated with the adoption of ASU 2016-09. New accounting pronouncements. In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases currently classified as operating leases and makes certain changes to the accounting for lease expenses. This update is effective for fiscal years beginning after December 15, 2018 and for interim periods beginning the following year. This update should be applied using a modified retrospective approach, and early adoption is permitted. The Company anticipates that the adoption of ASU 2016-02 for its leasing arrangements will likely (i) increase the Company's recorded assets and liabilities, (ii) increase depreciation, depletion and amortization expense, (iii) increase interest expense and (iv) decrease lease/rental expense. The Company is currently evaluating each of its lease arrangements and has not determined the aggregate amount of change expected for each category. |

Divestitures | Divestitures In February 2018, the Company announced its intention to divest its properties in the South Texas, Raton and West Panhandle fields and focus its efforts and capital resources on its Permian Basin assets. In April 2018, the Company completed the sale of approximately 10,200 net acres in the West Eagle Ford Shale to an unaffiliated third party for cash proceeds of $103 million , before normal closing adjustments. During the second quarter of 2018, the Company recognized a gain of $78 million associated with this divestiture. In June 2018, the Company entered into a purchase and sale agreement with an unaffiliated third party to sell all of its assets in the Raton Basin for cash proceeds of $79 million , before normal closing adjustments. Associated with the sale, the Company recorded a noncash impairment charge of $77 million in June 2018 to reduce the carrying value of its Raton Basin assets to their estimated fair value less costs to sell. See Note 4 for additional information about the Raton Basin impairment charge. The Company classified its Raton Basin assets and liabilities as held for sale in the accompanying consolidated balance sheet as of June 30, 2018 . The sale closed in July 2018. In July 2018, the Company signed a purchase and sale agreement to sell its assets in the West Panhandle field to an unaffiliated third party for cash proceeds of $201 million , before normal closing adjustments. See Note 16 for further information regarding the Company's sale of its West Panhandle field assets. The held for sale assets and liabilities in the accompanying consolidated balance sheet as of June 30, 2018 relate primarily to the Raton Basin assets. The Company had no assets held for sale as of December 31, 2017. June 30, 2018 (in millions) Composition of assets included in assets held for sale: Inventories $ 4 Other current assets 1 Oil and gas properties, net 122 Other property and equipment, net 27 Goodwill 1 Total assets $ 155 Composition of liabilities included in liabilities held for sale: Other current liabilities 3 Other noncurrent liabilities 71 Total liabilities $ 74 No assurance can be given that the remaining planned asset divestitures during 2018 will be completed in accordance with the Company's plan or on terms and at prices acceptable to the Company. In April 2017, the Company completed the sale of approximately 20,500 acres in the Martin County region of the Permian Basin, with net production of approximately 1,500 BOEPD, to an unaffiliated third party for cash proceeds of $264 million . The sale resulted in a gain of $194 million . In conjunction with this divestiture, the Company reduced the carrying value of goodwill by $2 million , reflecting the portion of the Company's goodwill related to the assets sold. During the six months ended June 30, 2017 , the Company completed the sales of nonstrategic proved and unproved properties in the Permian Basin for cash proceeds of $72 million , which resulted in a gain of $10 million . |
Fair Value Measurements

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The three input levels of the fair value hierarchy are as follows: • Level 1 – quoted prices for identical assets or liabilities in active markets. • Level 2 – quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates) and inputs derived principally from or corroborated by observable market data by correlation or other means. • Level 3 – unobservable inputs for the asset or liability. Assets and liabilities measured at fair value on a recurring basis. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety. The following table presents the Company's assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017 for each of the fair value hierarchy levels: Fair Value Measurement as of June 30, 2018 Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value as of June 30, 2018 (in millions) Assets: Commodity derivatives $ — $ 2 $ — $ 2 Deferred compensation plan assets 94 — — 94 Total assets 94 2 — 96 Liabilities: Commodity derivatives — 601 — 601 Total liabilities — 601 — 601 Total recurring fair value measurements $ 94 $ (599 ) $ — $ (505 ) Fair Value Measurement as of December 31, 2017 Using Quoted Prices Significant Significant Fair value as of December 31, 2017 (in millions) Assets: Commodity derivatives $ — $ 11 $ — $ 11 Deferred compensation plan assets 95 — — 95 Total assets 95 11 — 106 Liabilities: Commodity derivatives — 255 — 255 Total liabilities — 255 — 255 Total recurring fair value measurements $ 95 $ (244 ) $ — $ (149 ) Commodity derivatives. The Company's commodity derivatives represent oil, NGL and gas swap contracts, collar contracts and collar contracts with short puts. The asset and liability measurements for the Company's commodity derivative contracts represent Level 2 inputs in the hierarchy. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity derivatives. The asset and liability values attributable to the Company's commodity derivatives were determined based on inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) the implied rate of volatility inherent in the collar contracts and collar contracts with short puts, which is based on active and independent market-quoted volatility factors. Deferred compensation plan assets. The Company's deferred compensation plan assets represent investments in equity and mutual fund securities that are actively traded on major exchanges. These investments are measured based on observable prices on major exchanges. As of June 30, 2018 and December 31, 2017 , the significant inputs to these asset exchange values represented Level 1 independent active exchange market price inputs. Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventory, proved and unproved oil and gas properties and other long-lived assets that are written down to fair value when they are impaired or held for sale. Proved oil and gas properties . As a result of the Company's proved property impairment assessments, the Company recognized a noncash impairment charge of $285 million to reduce the carrying value of the Raton Basin field during the three months ended March 31, 2017 to its estimated fair value of $186 million . The Company calculated the fair value of the Raton Basin field as of March 31, 2017 using a discounted future cash flow model. Significant Level 3 assumptions associated with the calculation of the Raton Basin field's discounted future cash flows as of March 31, 2017 included management's longer-term commodity price outlook ("Management's Price Outlook") for oil of $53.65 per barrel ("Bbl") and gas of $3.00 per million British Thermal units ("MMBtu") and management's outlook for (i) production, (ii) capital expenditures, (iii) production costs and (iv) estimated proved reserves and risk-adjusted probable reserves. Management's Price Outlooks are developed based on third-party longer-term commodity futures price outlooks as of each measurement date. The expected future net cash flows were discounted using an annual rate of 10 percent to determine fair value. It is reasonably possible that the Company's estimate of undiscounted future net cash flows attributable to other properties may change in the future resulting in the need to impair their carrying values. The primary factors that may affect estimates of future cash flows are (i) future adjustments, both positive and negative, to proved and risk-adjusted probable and possible oil and gas reserves, (ii) results of future drilling activities, (iii) Management's Price Outlooks and (iv) increases or decreases in production and capital costs associated with these reserves. Assets held for sale. During the three and six months ended June 30, 2018 , the Company recognized an impairment charge of $77 million to reduce the carrying value of its Raton Basin field assets to the agreed upon sales price for these assets. See Note 3 for additional information about the Company's sale of its Raton Basin field assets. Financial instruments not carried at fair value. Carrying values and fair values of financial instruments that are not carried at fair value in the accompanying consolidated balance sheets as of June 30, 2018 and December 31, 2017 are as follows: June 30, 2018 December 31, 2017 Carrying Value Fair Value Carrying Value Fair Value (in millions) Commercial paper, corporate bonds and time deposits $ 704 $ 702 $ 1,279 $ 1,277 Current portion of long-term debt $ — $ — $ 449 $ 457 Long-term debt $ 2,285 $ 2,397 $ 2,283 $ 2,479 Commercial paper, corporate bonds and time deposits. Periodically, the Company invests in commercial paper and corporate bonds with investment grade rated entities. The Company also periodically enters into time deposits with financial institutions. The investments are carried at amortized cost and classified as held-to-maturity as the Company has the intent and ability to hold them until they mature. The carrying values of held-to-maturity investments are adjusted for amortization of premiums and accretion of discounts over the remaining life of the investment. Income related to these investments is recorded in interest and other income in the Company's consolidated statements of operations. The Company's investments in corporate bonds represent Level 1 inputs in the hierarchy, while other investments represent Level 2 inputs in the hierarchy. Commercial paper and time deposits are included in cash and cash equivalents if they have maturity dates that are less than 90 days at the date of purchase; otherwise, such investments are reflected in short-term investments or long-term investments in the accompanying consolidated balance sheets based on their maturity dates. The following tables provide the components of the Company's cash and cash equivalents and investments as of June 30, 2018 and December 31, 2017 : June 30, 2018 Consolidated Balance Sheet Location Cash Commercial Paper Corporate Bonds Time Deposits Total (in millions) Cash and cash equivalents $ 707 $ 35 $ — $ 50 $ 792 Short-term investments — 101 239 51 391 Long-term investments — — 313 — 313 $ 707 $ 136 $ 552 $ 101 $ 1,496 December 31, 2017 Consolidated Balance Sheet Location Cash Commercial Paper Corporate Bonds Time Total (in millions) Cash and cash equivalents $ 846 $ — $ — $ 50 $ 896 Short-term investments — 124 642 447 1,213 Long-term investments — — 66 — 66 $ 846 $ 124 $ 708 $ 497 $ 2,175 Debt obligations. The Company's debt obligations are composed of its senior notes whose fair value is determined utilizing inputs that are Level 2 measurements in the fair value hierarchy. The Company's senior notes represent debt securities that are quoted but not actively traded on major exchanges; therefore, fair values of the Company's senior notes are based on their periodic values as quoted on the major exchanges. The Company has other financial instruments consisting primarily of receivables, payables and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in a business combination, goodwill and asset retirement obligations. |

Derivative Financial Instruments | Derivative Financial Instruments The Company utilizes commodity swap contracts, collar contracts and collar contracts with short puts to (i) reduce the effect of price volatility on the commodities the Company produces and sells or consumes, (ii) support the Company's annual capital budgeting and expenditure plans and (iii) reduce commodity price risk associated with certain capital projects. The Company also, from time to time, utilizes interest rate contracts to reduce the effect of interest rate volatility on the Company's indebtedness. Periodically, the Company may pay a premium to enter into commodity contracts. Premiums paid, if any, have been nominal in relation to the value of the underlying asset in the contract. The Company recognizes the nominal premium payments as an increase to the value of derivative assets when paid. All derivatives are adjusted to fair value as of each balance sheet date. Oil production derivative activities. All material physical sales contracts governing the Company's oil production are tied directly to, or are highly correlated with, New York Mercantile Exchange ("NYMEX") West Texas Intermediate ("WTI") oil prices. The Company uses derivative contracts to manage oil price volatility and basis swap contracts to reduce basis risk between NYMEX prices and the actual index prices at which the oil is sold. The following table sets forth the volumes per day associated with the Company's outstanding oil derivative contracts as of June 30, 2018 and the weighted average oil prices for those contracts: 2018 Year Ending December 31, 2019 Third Quarter Fourth Quarter Collar contracts: Volume (Bbl) 3,000 3,000 — Price per Bbl: Ceiling $ 58.05 $ 58.05 $ — Floor $ 45.00 $ 45.00 $ — Collar contracts with short puts: Volume (Bbl) 154,000 159,000 65,000 Price per Bbl: Ceiling $ 57.70 $ 57.62 $ 60.74 Floor $ 47.34 $ 47.26 $ 52.69 Short put $ 37.31 $ 37.23 $ 42.69 NGL production derivative activities. All material physical sales contracts governing the Company's NGL production are tied directly or indirectly to either Mont Belvieu, Texas or Conway, Kansas NGL component product prices. The Company uses derivative contracts to manage NGL component price volatility. The following table sets forth the volumes per day associated with the Company's outstanding NGL derivative contracts as of June 30, 2018 and the weighted average NGL prices for those contracts: 2018 Year Ending December 31, 2019 Third Quarter Fourth Quarter Ethane basis swap contracts (a): Volume (MMBtu) 6,920 6,920 6,920 Price differential ($/MMBtu) $ 1.60 $ 1.60 $ 1.60 ____________________ (a) The ethane basis swap contracts reduce the price volatility of ethane forecasted for sale by the Company at Mont Belvieu, Texas-posted prices. The ethane basis swap contracts fix the basis differential on a NYMEX Henry Hub ("HH") MMBtu equivalent basis. The Company will receive the HH price plus the price differential on 6,920 MMBtu per day, which is equivalent to 2,500 Bbls per day of ethane. Gas production derivative activities. All material physical sales contracts governing the Company's gas production are tied directly or indirectly to HH gas prices or regional index prices where the gas is sold. The Company uses derivative contracts to manage gas price volatility and basis swap contracts to reduce basis risk between HH prices and actual index prices at which the gas is sold. The following table sets forth the volumes per day associated with the Company's outstanding gas derivative contracts as of June 30, 2018 and the weighted average gas prices for those contracts: 2018 Year Ending December 31, 2019 Third Quarter Fourth Quarter Swap contracts: Volume (MMBtu) 100,000 100,000 — Price per MMBtu $ 3.00 $ 3.00 $ — Collar contracts with short puts: Volume (MMBtu) 50,000 50,000 — Price per MMBtu: Ceiling $ 3.40 $ 3.40 $ — Floor $ 2.75 $ 2.75 $ — Short put $ 2.25 $ 2.25 $ — Basis swap contracts: Permian Basin index swap volume (MMBtu) (a) 60,000 60,000 44,877 Price differential ($/MMBtu) $ (1.46 ) $ (1.46 ) $ (1.46 ) Southern California index swap volume (MMBtu) (b) 80,000 66,522 84,932 Price differential ($/MMBtu) $ 0.30 $ 0.50 $ 0.33 ____________________ (a) The referenced basis swap contracts fix the basis differentials between the index price at which the Company sells its Permian Basin gas and the HH price used in swap contracts and collar contracts with short puts. (b) The referenced basis swap contracts fix the basis differentials between Permian Basin index prices and southern California index prices for Permian Basin gas forecasted for sale in Arizona and southern California. Marketing derivatives. Periodically, the Company enters into buy and sell marketing arrangements to fulfill firm pipeline transportation commitments. As of June 30, 2018 , the Company was party to July and August 2018 oil basis swap contracts for 3,000 Bbls per day of Permian Basin oil forecasted for sale to a Gulf Coast refinery with a price differential of $3.30 per Bbl between NYMEX WTI and Magellan East Houston oil prices. Tabular disclosure of derivative financial instruments . All of the Company's derivatives are accounted for as non-hedge derivatives as of June 30, 2018 and December 31, 2017 , and therefore all changes in the fair values of its derivative contracts are recognized as gains or losses in the earnings of the periods in which they occur. The Company classifies the fair value amounts of derivative assets and liabilities as net current or noncurrent derivative assets or net current or noncurrent derivative liabilities, whichever the case may be, by commodity and counterparty. The Company enters into derivatives under master netting arrangements, which, in an event of default, allows the Company to offset payables to and receivables from the defaulting counterparty. The aggregate fair value of the Company's derivative instruments reported in the accompanying consolidated balance sheets by type and counterparty, including the classification between current and noncurrent assets and liabilities, consists of the following: Fair Value of Derivative Instruments as of June 30, 2018 Type Consolidated Balance Sheet Location Fair Value Gross Amounts Offset in the Consolidated Balance Sheet Net Fair Value Presented in the Consolidated Balance Sheet (in millions) Derivatives not designated as hedging instruments Asset Derivatives: Commodity price derivatives Derivatives - current $ 9 $ (7 ) $ 2 Commodity price derivatives Derivatives - noncurrent $ 2 $ (2 ) — $ 2 Liability Derivatives: Commodity price derivatives Derivatives - current $ 519 $ (7 ) $ 512 Commodity price derivatives Derivatives - noncurrent $ 91 $ (2 ) 89 $ 601 Fair Value of Derivative Instruments as of December 31, 2017 Type Consolidated Balance Sheet Location Fair Value Gross Amounts Offset in the Consolidated Balance Sheet Net Fair Value Presented in the Consolidated Balance Sheet (in millions) Derivatives not designated as hedging instruments Asset Derivatives: Commodity price derivatives Derivatives - current $ 13 $ (2 ) $ 11 Commodity price derivatives Derivatives - noncurrent $ 3 $ (3 ) — $ 11 Liability Derivatives: Commodity price derivatives Derivatives - current $ 234 $ (2 ) $ 232 Commodity price derivatives Derivatives - noncurrent $ 26 $ (3 ) 23 $ 255 The following table details the location of gains and losses recognized on the Company's derivative contracts in the accompanying consolidated statements of operations: Derivatives Not Designated as Hedging Instruments Location of Gain/(Loss) Recognized in Earnings on Derivatives Three Months Ended Six Months Ended 2018 2017 2018 2017 (in millions) Commodity price derivatives Derivative gains (losses), net $ (358 ) $ 136 $ (566 ) $ 287 Interest rate derivatives Derivative gains (losses), net — (1 ) — (1 ) Total $ (358 ) $ 135 $ (566 ) $ 286 Derivative Counterparties . The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Legal actions. The Company is a party to various proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to such proceedings and claims will not have a material adverse effect on the Company's financial position as a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated. Obligations following divestitures. In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty obligations and income taxes. The Company does not believe these obligations are probable of having a material impact on its liquidity, financial position or future results of operations. Lease agreements. In June 2017, the Company entered into a 20 -year operating lease for the Company's new corporate headquarters that is currently being constructed in Irving, Texas. Annual base rent is expected to be $33 million and lease payments are expected to commence once the building is complete, which is anticipated to occur during the second half of 2019. The Company has a variable equity interest in the entity that is constructing the building. The Company is not the primary beneficiary of the variable interest entity and only has a profit sharing interest after certain economic returns are achieved. The Company has no exposure to the variable interest entity's losses or future liabilities, if any. The Company is the deemed owner of the building (for accounting purposes) during the construction period and is following the build-to-suit accounting guidance. Accordingly, as of June 30, 2018 , the Company has capitalized $119 million of construction costs, including capitalized interest, within other property and equipment and has recognized a corresponding build-to-suit lease liability. The recording of these assets and liabilities are considered noncash investing and financing items, respectively, for purposes of the consolidated statements of cash flows. Firm purchase, gathering, processing, transportation, and fractionation commitments. The Company from time to time enters into, and as of June 30, 2018 was a party to, take-or-pay agreements, which include contractual commitments to purchase sand and water for use in the Company's drilling operations and contractual commitments with midstream service companies and pipeline carriers for future gathering, processing, transportation, storage and fractionation. These commitments are normal and customary for the Company's business activities. |

Revenue from Contract with Customer [Abstract] | |
Revenue Recognition | Revenue Recognition Impact of ASC 606 adoption. On January 1, 2018, the Company adopted ASC 606 by applying the modified retrospective method to all revenue contracts as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting under ASC 605. The Company completed a detailed review of its revenue contracts, which represent all of the Company's revenue streams including oil, NGL and gas sales and sales of purchased oil and gas, to determine the effect of the new standard for the three and six months ended June 30, 2018 . The Company did not record a change to its opening retained earnings as of January 1, 2018 as there was no material change to the timing or pattern of revenue recognition due to the adoption of ASC 606. The adoption of ASC 606 as of January 1, 2018 had the following impact on the Company's results of operations for the three and six months ended June 30, 2018 : Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 As Reported ASC 605 (Without Adoption of ASC 606) Effect of Change Higher (Lower) As Reported ASC 605 Effect of Change (in millions) (in millions) Revenues and other income: Oil and gas $ 1,286 $ 1,232 $ 54 $ 2,552 $ 2,455 $ 97 Costs and expenses: Oil and gas production $ 243 $ 189 $ 54 $ 456 $ 359 $ 97 Changes in oil and gas revenues and oil and gas production costs (specifically gathering, processing and transportation costs) are due to the conclusion under the control model in ASC 606 that the third-party processor or transporter is only providing gas processing or transportation services and that the Company remains the principal owner of the commodity until sold to the ultimate purchaser. This is a change from ASC 605 where the Company historically recorded gas processing fees as a reduction of revenue recognized by the Company, as these fees were considered necessary to separate the wet gas stream into its sellable components (i.e., dry gas and individual NGL components). Under ASC 605, third-party processing and transportation companies were determined to have control of the commodities being processed and transported. As a result of adopting ASC 606, the Company has modified its presentation of revenues and expenses for these arrangements. Revenues related to these agreements are now presented on a gross basis for amounts expected to be received from third-party purchasers through the marketing process. Gathering, processing and transportation expenses related to these agreements, incurred prior to the transfer of control to the purchaser, are now presented as oil and gas production costs. Disaggregated revenue from contracts with purchasers. Revenues on sales of oil, NGLs, gas and purchased oil and gas are recognized when control of the product is transferred to the purchaser and payment can be reasonably assured. Sales prices for oil, NGL and gas production are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to the pipeline or market, commodity quality and prevailing supply and demand conditions. As such, the prices of oil, NGLs and gas generally fluctuate based on the relevant market index rates. The following table provides information about disaggregated revenue from contracts with purchasers by product type: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 (in millions) Oil sales $ 1,033 $ 2,046 NGL sales 169 334 Gas sales 84 172 Total oil and gas sales 1,286 2,552 Sales of purchased oil and gas 1,095 2,166 Total revenue derived from contracts with purchasers $ 2,381 $ 4,718 Oil sales . Sales under the Company's oil contracts are generally considered performed when the Company sells oil production at the wellhead and receives an agreed-upon index price, net of any price differentials. The Company recognizes revenue when control transfers to the purchaser at the wellhead based on the net price received. NGL and gas sales . The Company evaluated whether it was the principal or the agent in natural gas processing transactions and concluded that it is the principal when it has the ability to take-in-kind, which is the case in the majority of the Company's gas processing and transportation contracts. Therefore, beginning January 1, 2018, the Company began recognizing revenue on a gross basis, with the gathering, processing and transportation costs associated with its take-in-kind arrangements being recognized as oil and gas production costs in the Company's accompanying consolidated statement of operations. Gas and NGL processing fees previously reflected as a reduction in the Company's reported gas and NGL revenue are now recognized as an expense in the Company's production costs. Sales of purchased oil and gas . The Company periodically enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's WTI oil sales to the Gulf Coast refinery or international export markets and to satisfy unused pipeline capacity commitments. Revenues and expenses from these transactions are presented on a gross basis as the Company acts as a principal in the transaction by assuming control of the commodities purchased and the responsibility to deliver the commodities sold. Revenue is recognized when control transfers to the purchaser at the delivery point based on the price received from the purchaser. The transportation costs associated with these transactions are presented as a component of purchased oil and gas expense. Firm transportation payments on excess pipeline capacity are included in other expense in the accompanying consolidated statements of operations. Performance obligations and contract balances. The majority of the Company's product sale commitments are short-term in nature with a contract term of one year or less. The Company typically satisfies its performance obligations upon transfer of control as described above in Disaggregated revenue from contracts with purchasers and records the related revenue in the month production is delivered to the purchaser. Settlement statements for sales of oil, NGLs and gas and sales of purchased oil and gas may not be received for 30 to 60 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. The implementation of ASC 606 has not changed existing controls around revenue estimates and the accrual process. Historically, differences between the Company's revenue estimates and actual revenue received have not been significant. As of June 30, 2018 and December 31, 2017 , the accounts receivable balance representing amounts due or billable under the terms of contracts with purchasers was $799 million and $594 million , respectively. |

(b) Loss from vertical integration services primarily represents net margins (attributable to third party working interest owners) that result from Company-provided fracture stimulation and well service operations, which are ancillary to and supportive of the Company's oil and gas joint operating activities, and do not represent intercompany transactions. For the three and six months ended June 30, 2018 , these vertical integration net margins included $30 million and $65 million , respectively, of revenues and $33 million and $74 million , respectively, of costs and expenses. For the same respective periods in 2017, these vertical integration net margins included $23 million and $42 million of revenues and $28 million and $53 million of costs and expenses. |

Income Taxes | Income Taxes The Company's income tax provision consisted of the following for the three and six months ended June 30, 2018 and 2017 : Three Months Ended Six Months Ended 2018 2017 2018 2017 (in millions) Deferred tax provision $ 19 $ 121 69 90 For the three and six months ended June 30, 2018 , the Company's effective tax rate, excluding income attributable to noncontrolling interests, was 23 percent and 22 percent , respectively, as compared to an effective rate of 34 percent and 32 percent for the same respective periods in 2017 . The U.S. statutory rate for the three and six months ended June 30, 2018 was 21 percent , reflecting the reduction in the federal corporate income tax rate from 35 percent to 21 percent beginning in 2018 as a result of the Tax Cuts and Jobs Act that was enacted in December 2017. The Company's effective tax rate for the six months ended June 30, 2017 differs from the U.S. statutory rate in effect during 2017 of 35 percent primarily due to recognizing excess tax benefits of $8 million associated with the adoption of ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting," which requires excess tax benefits or deficiencies associated with the vesting of long-term incentive awards to be recorded as income tax expense or benefit in the statement of operations rather than as an adjustment to additional paid-in capital in the balance sheet. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based upon the technical merits of the position. As of June 30, 2018 and December 31, 2017 , the Company had cumulative unrecognized tax benefits of $129 million and $124 million , respectively, resulting from research and experimental expenditures related to horizontal drilling and completions innovations. If all or a portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit will be recognized as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the period it is recognized. The timing as to when the Company will substantially resolve the uncertainties associated with the unrecognized tax benefit is uncertain. The Company files income tax returns in the U.S. federal and various state and foreign jurisdictions. The Internal Revenue Service has closed examinations of the 2012 and prior tax years and, with few exceptions, the Company believes that it is no longer subject to examinations by state and foreign tax authorities for years before 2012. As of June 30, 2018 , no adjustments had been proposed in any jurisdiction that would have a significant effect on the Company's liquidity, future results of operations or financial position. |

In the opinion of management, the consolidated financial statements of the Company as of June 30, 2018 and for the three and six months ended June 30, 2018 and 2017 include all adjustments and accruals, consisting only of normal, recurring accrual adjustments, which are necessary for a fair presentation of the results for the interim periods. These interim results are not necessarily indicative of results for a full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed in or omitted from this report pursuant to the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). These consolidated financial statements should be read together with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . Certain reclassifications have been made to the 2017 financial statement and footnote amounts in order to conform to the 2018 presentation. |
New accounting pronouncements | New accounting pronouncements. In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases currently classified as operating leases and makes certain changes to the accounting for lease expenses. This update is effective for fiscal years beginning after December 15, 2018 and for interim periods beginning the following year. This update should be applied using a modified retrospective approach, and early adoption is permitted. The Company anticipates that the adoption of ASU 2016-02 for its leasing arrangements will likely (i) increase the Company's recorded assets and liabilities, (ii) increase depreciation, depletion and amortization expense, (iii) increase interest expense and (iv) decrease lease/rental expense. The Company is currently evaluating each of its lease arrangements and has not determined the aggregate amount of change expected for each category. |
