Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of the Company, including its wholly‑owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The financial statements included herein were prepared from the records of the Company in accordance with generally accepted accounting principles in the United States (“GAAP”). In the opinion of management, all adjustments, consisting primarily of normal recurring accruals that are considered necessary for a fair statement of the consolidated financial information, have been included. Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of assumptions, judgments and estimates include (1) oil and gas reserves; (2) cash flow estimates used in impairment testing of oil and gas properties and goodwill; (3) depreciation, depletion, amortization and accretion; (4) asset retirement obligations; (5) assigning fair value and allocating purchase price in connection with business combinations, including the determination of any resulting goodwill; (6) accrued revenue and related receivables; (7) valuation of commodity derivative instruments; (8) accrued liabilities; (9) valuation of unit and stock-based payments, and (10) income taxes. Although management believes these estimates are reasonable, actual results could differ from these estimates. The Company evaluates its estimates on an on‑going basis and bases its estimates on historical experience and on various other assumptions the Company believes to be reasonable under the circumstances. Cash and Cash Equivalents Cash and cash equivalents consist of all highly liquid investments that are readily convertible into cash and have original maturities of three months or less when purchased. Restricted Cash Restricted cash represents cash that is unavailable for use in the Company's general operations. The Company had no restricted cash as of December 31, 2018 and 2017 . Cash Held in Escrow Cash held in escrow includes deposits for the purchase of certain oil and gas properties as required under the related purchase and sale agreements. The Company had no cash held in escrow as of December 31, 2018 and 2017 . Accounts Receivable The Company records estimated oil and gas revenue receivable from third parties at its net revenue interest. The Company also reflects costs incurred on behalf of joint interest partners in accounts receivable. The Company generally has the ability to withhold future revenue disbursements to recover non‑payment of joint interest billings. On an on‑going basis, management reviews accounts receivable amounts for collectability and records its allowance for uncollectible receivables under the specific identification method. The Company did not record any allowance for uncollectible receivables as of or for the years ended December 31, 2018 and 2017 . Credit Risk and Other Concentrations The Company’s cash and cash equivalents are exposed to concentrations of credit risk. The Company manages and controls this risk by investing these funds with major financial institutions. The Company often has balances in excess of the federally insured limits. The Company sells oil, natural gas and NGL to various types of customers, including oil marketers, pipelines and refineries. Credit is extended based on an evaluation of the customer’s financial conditions and historical payment record. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside the Company’s control, none of which can be predicted with certainty. For the three years ended December 31, 2018 , the Company had the following customers that exceeded 10% of total oil, natural gas and NGL revenues. The Company does not believe the loss of any single purchaser would materially impact its operating results because crude oil, natural gas and NGL are fungible products with well‑established markets and numerous purchasers. For the Year Ended December 31, 2018 2017 2016 Customer A 76 % 65 % 25 % Customer B 11 % 19 % 19 % Customer C — % 11 % — % Customer D — % — % 23 % Customer E — % — % 16 % At December 31, 2018 , the Company had commodity derivative contracts with eleven counterparties, all of whom are lenders under our credit agreement. The Company does not require collateral or other security from counterparties to support derivative instruments; however, to minimize the credit risk in derivative instruments, it is the Company’s policy to enter into derivative contracts only with counterparties that are credit worthy financial institutions deemed by management as competent and competitive market‑makers. Additionally, the Company uses master netting agreements to minimize credit‑risk exposure. The credit worthiness of the Company’s counterparties is subject to periodic review. For the years ended December 31, 2018 , 2017 and 2016 , the Company did not incur any losses with respect to counterparty contracts. None of the Company’s existing derivative instrument contracts contains credit‑risk related contingent features. Inventory and Prepaid Expenses The Company records well equipment inventory at the lower of cost or net realizable value. Prepaid expenses are recorded at cost. Inventory and prepaid expenses are comprised of the following (in thousands): As of December 31, 2018 2017 Well equipment inventory $ 19,916 $ 9,971 Prepaid expenses 6,900 3,046 $ 26,816 $ 13,017 Additionally, the Company recognized approximately $0.1 million , $0.7 million and $0.4 million of impairment expense on well equipment inventory for the years ended December 31, 2018 , 2017 and 2016 , respectively. Oil and Gas Properties The Company follows the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units‑of‑production basis over the remaining life of proved reserves and proved developed reserves, respectively. For the years ended December 31, 2018 , 2017 and 2016 , the Company excluded $144.3 million , $127.4 million and $98.7 million of capitalized costs from depletion related to wells in progress, respectively. For the years ended December 31, 2018 , 2017 and 2016 , the Company recorded depletion expense on capitalized oil and gas properties of $426.8 million , $306.7 million and $197.4 million , respectively. The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Costs incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed at each period end. Due to the capital‑intensive nature and the geological characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability. As of December 31, 2018 , the Company had approximately $6.1 million of suspended well costs, all capitalized less than one year and included in wells in progress at December 31, 2018 . These exploratory well costs are pending further engineering evaluation and analysis to determine if economic quantities of oil and gas reserves have been discovered. The Company expects its analysis to be complete in the second half of 2019. As of December 31, 2017 , $15.7 million of suspended well costs, all capitalized less than one year and included in wells in progress as of December 31, 2017 . At September 30, 2018, the Company completed its evaluation and moved $17.9 million of these suspended well costs to proved oil and gas properties based on the determination of proved reserves. As of December 31, 2016 , the Company had no suspended well costs recorded. Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense. The Company expensed $0.4 million and $1.4 million of costs associated with exploratory geological and geophysical costs for the years ended December 31, 2018 and 2017, respectively. There were no exploratory geological and geophysical costs incurred for the year ended December 31, 2016. The Company capitalizes interest, if debt is outstanding, during drilling operations in its exploration and development activities. For the years ended December 31, 2018 , 2017 and 2016 , the Company capitalized interest of approximately $8.2 million , $11.1 million and $5.2 million , respectively. Net carrying values of retired, sold or abandoned properties that constitute less than a complete unit of depreciable property are charged or credited, net of proceeds, to accumulated depreciation, depletion and amortization unless doing so significantly affects the unit-of-production amortization rate, in which case a gain or loss is recognized in income. Gains or losses from the disposal of complete units of depreciable property are recognized to earnings. For sales of entire working interests in unproved properties, gain or loss is recognized to the extent of the difference between the proceeds received and the net carrying value of the property. Proceeds from sales of partial interests in unproved properties are accounted for as a recovery of costs unless the proceeds exceed the entire cost of the property. Impairment of Oil and Gas Properties Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. For all of its fields, the Company estimates the expected future cash flows of its oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production estimates, estimated future capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and goodwill in the consolidated statements of operations, which increases accumulated depletion, depreciation and amortization. For the years ended December 31, 2018 and 2016 , the Company recognized $16.2 million and $22.5 million , respectively, in impairment expense on proved oil and gas properties in the Company's northern field. As of September 30, 2018, the future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in its northern field. As of June 30, 2016, it was determined that the proved oil and gas properties had no remaining fair value, therefore, the full net book value of these proved oil and gas properties were impaired. For the year ended December 31, 2017 , the Company recognized no impairment expense on proved oil and gas properties. Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. The Company evaluates significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit‑of‑production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration expenses in the consolidated statements of operations. As a result of the abandonment and impairment of unproved properties, the Company recognized $25.7 million , $15.8 million and $22.3 million in impairment expense for the years ended December 31, 2018 , 2017 and 2016 , respectively. Other Property and Equipment Other property and equipment consists of (i) other property and equipment including, office furniture and fixtures, leasehold improvements and computer hardware and software, (iii) compressors used in Extraction’s oil and gas operations, (iii) land, compressor stations, central tank batteries, and disposal well facilities and (iv) rights of ways, pipeline, and engineering costs. Impairment expense for other property and equipment is reported in impairment of long lived assets and goodwill in the consolidated statements of operations. The Company recognized $0.4 million , $0.9 million and $0.5 million in impairment expense related to midstream facilities for the years ended December 31, 2018 , 2017 and 2016 , respectively, which increased accumulated depreciation recognized in other property and equipment, net of accumulated depreciation. The Company recognized the impairment expense for the year ended December 31, 2018 and 2017 primarily as the result of right-of-way options that were no longer in the Company's plans for developing midstream infrastructure. The Company recognized the impairment expense for the years ended December 31, 2016, as the result of contraction in the local oil and gas industry’s near term growth profile, therefore decreasing the need and support for a specifically proposed gas processing facility. Gain or loss on the sale of other property and equipment is reported in (gain) loss on sale of property and equipment in the consolidated statement of operations. The Company recognized $0.5 million of loss on the sale of other property and equipment related to the disposal of an oil pipeline that was not yet placed into service in the first quarter of 2017. Other property and equipment is recorded at cost and depreciated using the straight‑line method. The estimated useful lives of those assets depreciated under the straight-line basis are as follows: Rental equipment 1-10 years Office leasehold improvements 3-10 years Other 3-5 years Other property and equipment is comprised of the following (in thousands): As of December 31, 2018 2017 Rental equipment $ 4,043 $ 3,805 Land 27,595 22,991 Right-of-ways and pipeline 8,008 7,447 Office leasehold improvements 7,231 4,405 Other 6,946 5,578 Less: accumulated depreciation and impairment (13,974 ) (11,797 ) $ 39,849 $ 32,429 Gathering Systems and Facilities Gathering systems and facilities consist of midstream assets such as land, rights of way, pipelines, equipment and construction and engineering costs associated with the construction of pipeline infrastructure to serve the development of the Company's acreage in its Hawkeye and Southwest Wattenberg areas. Approximately $112.3 million of gathering system and facilities assets have not been placed into service and therefore are not currently being depreciated. The Company will determine the estimated use lives of these assets when they are placed into service. Gathering systems and facilities is comprised of the following (in thousands): As of December 31, 2018 2017 Gathering systems and facilities 112,281 4,889 Land associated with gathering systems and facilities 2,188 — Less: accumulated depreciation — — $ 114,469 $ 4,889 Equity Method Investments Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the equity method. The Company recorded $15.5 million and $8.3 million of such investments included in other non-current assets on the consolidated balance sheets as of December 31, 2018 and 2017 , respectively. The Company recognized $2.9 million and $0.4 million of income from such investments, including the accretion of any basis difference between the carrying amount of the investment and the amount of underlying equity in net assets, included in other income on the consolidated statements of operations and equity in earnings of unconsolidated subsidiary, in which we have a minority ownership interest on the consolidated statements of cash flows for the year ended December 31, 2018 and 2017 , respectively. The Company held no such investments during the years ended December 31, 2016. On August 3, 2018, Elevation received proceeds of $83.6 million and recognized a gain of $83.6 million for year ended December 31, 2018 , upon the sale of assets of DJ Holdings, LLC, a subsidiary of Discovery Midstream Partners, LP, of which Elevation held a 10% membership interest. The Company acquired its interest in exchange for the contribution of an acreage dedication, which is considered a nonfinancial asset. Deferred Lease Incentives All incentives received from landlords for office leasehold improvements are recorded as deferred lease incentives and amortized over the term of the respective lease on a straight‑line basis as a reduction of rental expense. Please refer to Recent Accounting Pronouncements for discussion related to Accounting Standard Update No. 2016-02, which updates the GAAP related to deferred lease incentives and will be effective as of January 1, 2019. Debt Discount Costs The $430.0 million in Second Lien Notes issued in May of 2014 were issued at a 1.5% original issue discount (“OID”) and the debt discount of $6.5 million was recorded as a reduction of the Second Lien Notes. The debt discount costs related to Second Lien Notes were amortized to interest expense using the effective interest method over the term of the debt. Debt Issuance Costs Debt issuance costs include origination, legal, engineering, and other fees incurred to issue the debt in connection with the Company’s credit facility, 2021 Senior Notes, 2024 Senior Notes and 2026 Senior Notes (collectively, the "Senior Notes"). Debt issuance costs related to the credit facility are included in other non-current assets on the consolidated balance sheets and amortized to interest expense on the consolidated statement of operations on a straight‑line basis over the respective borrowing term. Debt issuance costs related to the Senior Notes are amortized to interest expense using the effective interest method over the term of the debt. Commodity Derivative Instruments The Company has entered into commodity derivative instruments to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. The commodity derivative instruments are measured at fair value and are included in the accompanying balance sheets as commodity derivative assets and commodity derivative liabilities. The Company has not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, the Company does not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivative gain (loss) line on the consolidated statements of operations. The Company’s cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in the Company’s consolidated statements of cash flows. Any premiums paid on derivative contracts are capitalized as part of the derivative assets or derivative liabilities, as appropriate, at the time the premiums are paid. Premium payments are reflected in cash flows from operating activities in the Company's consolidated statements of cash flows. Over time, as the derivative contracts settle, the differences between the cash received and the premiums paid or fair value of contracts acquired are recognized in net gains or losses on commodity or interest rate derivate contracts, and the cash received is reflected in cash flows from operating activities in the Company's consolidated statements of cash flows. The Company’s valuation estimate takes into consideration the counterparties’ credit worthiness, the Company’s credit worthiness, and the time value of money. The consideration of these factors result in an estimated exit‑price for each derivative asset or liability under a market place participant’s view. Management believes that this approach provides a reasonable, non‑biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please refer to Note 6 — Commodity Derivative Instruments for additional discussion on commodity derivative instruments. Goodwill and Other Intangible Assets The Company applies the provisions of ASC 350, Intangibles-Goodwill and Other . Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in business combinations. The Company tests goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test is performed at the reporting unit level, which represents the Company’s oil and gas operations in its core DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of the Company’s common shares could change the estimates of the fair value of the reporting unit and could result in an impairment charge. The Company performed a quantitative assessment as of September 30, 2018, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company identified triggering events as of December 31, 2018, due to the decrease in commodity pricing and the quoted market price of the Company's common shares compared to September 30, 2018. As such, the Company performed a quantitative assessment as of December 31, 2018 , utilizing an income approach based on estimates of the expected discounted future cash flows of the reporting unit's oil and gas properties, which concluded the fair value of the reporting unit was not greater than its carrying amount. As a result, the Company recorded goodwill impairment of $54.2 million , the entirety of the balance, for the year ended December 31, 2018 . The Company performed a quantitative assessment as of September 30, 2017, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company performed a qualitative assessment as of December 31, 2017 and 2016, which concluded the fair value of the reporting unit was more-likely-than-not greater than its carrying amount. Costs relating to the acquisition of internal-use software licenses are capitalized when incurred and amortized over the estimated useful life of the license, which is typically one to three years. The Company recorded $3.0 million , $2.3 million and $0.3 million of internal-use software for the years ended December 31, 2018 , 2017 and 2016 , respectively, on the consolidated balance sheets within the goodwill and other intangible assets line item. Accumulated amortization for the years ended December 31, 2018 , and 2017 was $3.1 million and $1.1 million , respectively. The Company recognized $2.1 million , $1.0 million and $0.1 million amortization expense for the years ended December 31, 2018 , 2017 and 2016 , respectively. Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above) and long‑term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are representative of their fair values due to their short‑term maturities. The carrying amount of the Company’s credit facility approximates fair value as it bears interest at variable rates over the term of the loan. The Company’s Senior Notes are recorded at cost and the fair value is disclosed in Note 8 — Fair Value Measurements . Considerable judgment is required to develop estimates of fair value. The estimates provided are not necessarily indicative of the amounts the Company would realize upon the sale or refinancing of such instruments. Asset Retirement Obligation The Company recognizes estimated liabilities for future costs associated with the abandonment of its oil and gas properties. A liability for the fair value of an asset retirement obligation and corresponding increase to the carrying value of the related long‑lived asset are recorded at the time the Company makes the decision to complete the well or a well is acquired. For additional discussion on asset retirement obligations please refer to Note 7 — Asset Retirement Obligations. Environmental Liabilities The Company is subject to federal, state and local environmental laws and regulations. These laws regulate the release, disposal or discharge of materials into the environment or otherwise relating to environmental protection and may require the Company to remove or mitigate the environmental effects of the discharge, disposal or release of petroleum substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed. Liabilities for expenditures of a non‑capital nature are recorded when environmental assessments and/or remediation is probable, and the costs can be reasonably estimated. Such liabilities are generally undiscounted values unless the timing of cash payments for the liability or component is fixed or determinable. Management has determined that no significant environmental liabilities existed as of December 31, 2018 . Revenue Recognition Revenues from the sale of oil, natural gas and NGL are recognized when the product is delivered at a fixed or determinable price, title has transferred, and collectability is reasonably assured and evidenced by a contract. The Company recognizes revenues from the sale of oil, natural gas and NGL using the sales method of accounting, whereby revenue is recorded based on the Company’s share of volume sold, regardless of whether the Company has taken its proportional share of volume produced. A receivable or liability is recognized only to the extent that the Company has an imbalance on a specific property greater than the expected remaining proved reserves. As of December 31, 2018 , the Company has an oil imbalance of 22 MBbl, which the Company intends to settle with the counterparty in crude oil barrels. There were no material imbalances at December 31, 2017 or 2016 . On January 1, 2018, the Company adopted ASC 606 - Revenue from Contracts with Customers ("ASC 606"). See Adoption of ASC 606 for more information regarding the adoption of this standard. Unit and Stock‑Based Payments The Company and its predecessor, Holdings, has granted restricted unit awards ("RUAs"), restricted stock units ("RSUs"), stock option awards and performance stock awards ("PSAs") to certain directors, officers and employees of the Company, which therefore required the Company to recognize the expense in its financial statements. All unit and stock‑based payments to directors, officers and employees are measured at fair value on the grant date and expensed over the relevant service period. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All unit and stock‑based payment expense is recognized using the straight‑line method and is included within general and administrative expenses in the consolidated statements of operations and unit and stock-based compensation in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 11 — Unit and Stock‑Based Compensation for additional discussion on unit and stock‑based payments. Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The tax returns and the amount of taxable income or loss are subject to examination by deferral and state taxing authorities. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets, including net operating losses. In making this determination, the Company considers all the available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends, and its outlook for future years. The Company believes it is more likely than not that certain net operating losses can be carried forward and utilized. 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 on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company does not currently have uncertain tax positions. On December 22, 2017, United States legislation referred to as the Tax Cuts and Jobs Act (the "TCJA") was signed into law. Many of the provisions of the TCJA are effective for taxable years beginning after December 31, 2017. The TCJA includes changes to the Internal Revenue Code of 1986 (as amended, the "Code"). The most significant change included in the TCJA is a reduction in the corporate federal income tax rate from 35% to 21%. As a result of the enactment date of December 22, 2017, the Company was required to remeasure the deferred tax assets and liabilities at the rate in which they are expected to reverse. This re-measurement of deferred tax assets and liabilities required the Company to analyze and record a one-time adjustment to reduce the overall deferred tax liability in the con |

Acquisitions | Acquisitions and Divestitures Assets Held for Sale In January 2019, the Company entered into a definitive agreement with an unaffiliated oil and gas company to sell approximately 5,000 net acres of leasehold and producing properties primarily in Weld County, Colorado (the "Proposed March 2019 Divestiture") from its exploration and production segment. Upon closing, the Company will receive total consideration of approximately $22.4 million in cash, subject to customary purchase price adjustments.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Commodity Derivative Instruments | Commodity Derivative Instruments The Company has entered into commodity derivative instruments, as described below. The Company has utilized swaps, put options and call options to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. A swap has an established fixed price. When the settlement price is below the fixed price, the counterparty pays the Company an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. When the settlement price is above the fixed price, the Company pays its counterparty an amount equal to the difference between the settlement price and the fixed price multiplied by the hedged contract volume. A put option has an established floor price. The buyer of the put option pays the seller a premium to enter into the put option. When the settlement price is below the floor price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is above the floor price, the put option expires worthless. Some of the Company’s purchased put options have deferred premiums. For the deferred premium puts, the Company agrees to pay a premium to the counterparty at the time of settlement. A call option has an established ceiling price. The buyer of the call option pays the seller a premium to enter into the call option. When the settlement price is above the ceiling price, the seller pays the buyer an amount equal to the difference between the settlement price and the strike price multiplied by the hedged contract volume. When the settlement price is below the ceiling price, the call option expires worthless. The Company combines swaps, purchased put options, purchased call options, sold put options and sold call options in order to achieve various hedging strategies. Some examples of the Company’s hedging strategies are collars which include purchased put options and sold call options, three-way collars which include purchased put options, sold put options and sold call options, and enhanced swaps, which include either sold put options or sold call options with the associated premiums rolled into an enhanced fixed price swap. The objective of the Company’s use of commodity derivative instruments is to achieve more predictable cash flows in an environment of volatile oil and gas prices and to manage its exposure to commodity price risk. While the use of these commodity derivative instruments limits the downside risk of adverse price movements, such use may also limit the Company’s ability to benefit from favorable price movements. The Company may, from time to time, add incremental derivatives to hedge additional production, restructure existing derivative contracts or enter into new transactions to modify the terms of current contracts in order to realize the current value of the Company’s existing positions. The Company does not enter into derivative contracts for speculative purposes. The use of derivatives involves the risk that the counterparties to such instruments will be unable to meet the financial terms of such contracts. The Company’s derivative contracts are currently with eleven counterparties, all of whom are lenders under our credit agreement. The Company has netting arrangements with the counterparties that provide for the offset of payables against receivables from separate derivative arrangements with the counterparties in the event of contract termination. The derivative contracts may be terminated by a non‑defaulting party in the event of default by one of the parties to the agreement. There are no credit‑risk‑related contingent features or circumstances in which the features could be triggered in derivative instruments that are in a net liability position at the end of the reporting period. The Company’s commodity derivative contracts as of December 31, 2018 are summarized below: 2019 2020 NYMEX WTI Crude Swaps: Notional volume (Bbl) 900,000 1,200,000 Weighted average fixed price ($/Bbl) $ 52.56 $ 52.66 NYMEX WTI Crude Sold Calls: Notional volume (Bbl) 11,700,000 1,800,000 Weighted average sold call price ($/Bbl) $ 65.40 $ 67.53 NYMEX WTI Crude Sold Puts: Notional volume (Bbl) 13,500,000 1,800,000 Weighted average sold put price ($/Bbl) $ 41.27 $ 42.00 NYMEX WTI Crude Purchased Puts: Notional volume (Bbl) 17,850,000 1,800,000 Weighted average purchased put price ($/Bbl) $ 47.67 $ 50.00 NYMEX HH Natural Gas Swaps: Notional volume (MMBtu) 32,400,000 — Weighted average fixed price ($/MMBtu) $ 2.81 — NYMEX HH Natural Gas Purchased Puts: Notional volume (MMBtu) 3,600,000 — Weighted average purchased put price ($/MMBtu) $ 3.04 — NYMEX HH Natural Gas Sold Calls: Notional volume (MMBtu) 3,600,000 — Weighted average sold call price ($/MMBtu) $ 3.46 — NYMEX HH Natural Gas Sold Puts: Notional volume (MMBtu) 3,000,000 — Weighted average sold put price ($/MMBtu) $ 2.50 — CIG Basis Gas Swaps: Notional volume (MMBtu) 36,000,000 — Weighted average fixed basis price ($/MMBtu) $ (0.75 ) — The following tables detail the fair value of the Company’s derivative instruments, including the gross amounts and adjustments made to net the derivative instruments for the presentation in the balance sheets (in thousands): As of December 31, 2018 Net Amounts of Gross Amounts Assets and of Recognized Gross Amounts Liabilities Gross Amounts Assets and Offset in the Presented in the not Offset in the Net Location on Balance Sheet Liabilities Balance Sheet (1) Balance Sheet Balance Sheet (2) Amounts (3) Current assets (4) $ 115,852 $ (66,945 ) $ 48,907 $ (192 ) $ 57,147 Non-current assets $ 17,217 $ (8,785 ) $ 8,432 $ — $ — Current liabilities (4) $ (67,141 ) $ 66,945 $ (196 ) $ 192 $ (4 ) Non-current liabilities $ (8,785 ) $ 8,785 $ — $ — $ — As of December 31, 2017 Net Amounts of Gross Amounts Assets and of Recognized Gross Amounts Liabilities Gross Amounts Assets and Offset in the Presented in the not Offset in the Net Location on Balance Sheet Liabilities Balance Sheet (1) Balance Sheet Balance Sheet (2) Amounts (3) Current assets $ 22,118 $ (17,986 ) $ 4,132 $ — $ 4,132 Non-current assets $ 13,686 $ (13,686 ) $ — $ — $ — Current liabilities $ (85,414 ) $ 17,986 $ (67,428 ) $ — $ (84,702 ) Non-current liabilities $ (30,960 ) $ 13,686 $ (17,274 ) $ — $ — (1) Agreements are in place with all of the Company’s financial trading counterparties that allow for the financial right of offset for derivative assets and derivative liabilities at settlement or in the event of a default under the agreements.

Asset Retirement Obligation Disclosure [Abstract] | |
Asset Retirement Obligations | Asset Retirement Obligations The Company follows accounting for asset retirement obligations in accordance with ASC 410, Asset Retirement and Environmental Obligations , which requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it was incurred if a reasonable estimate of fair value could be made. The Company’s asset retirement obligations primarily represent the estimated present value of the amounts expected to be incurred to plug, abandon and remediate producing and shut‑in wells at the end of their productive lives in accordance with applicable local, state and federal laws, and applicable lease terms. The Company determines the estimated fair value of its asset retirement obligations by calculating the present value of estimated cash flows related to plugging and abandonment liabilities. The significant inputs used to calculate such liabilities include estimates of costs to be incurred; the Company’s credit adjusted discount rates, inflation rates and estimated dates of abandonment. The asset retirement liability is accreted to its present value each period and the capitalized asset retirement costs are depleted with proved oil and gas properties using the unit of production method. The following table summarizes the activities of the Company’s asset retirement obligations for the periods indicated (in thousands): For the Year Ended December 31, 2018 2017 Balance beginning of period $ 69,540 $ 56,108 Liabilities incurred or acquired 2,136 9,802 Liabilities settled (13,869 ) (4,169 ) Revisions in estimated cash flows 6,800 2,630 Accretion expense 5,184 5,169 Balance end of period $ 69,791 $ 69,540 |
Fair Value Measurements

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements ASC 820, Fair Value Measurement and Disclosure , establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: • Level 1: Quoted prices are available in active markets for identical assets or liabilities; • Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; • Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations. The financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. There were no transfers between levels during any periods presented below. The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2018 and December 31, 2017 by level within the fair value hierarchy (in thousands): Fair Value Measurements at December 31, 2018 Using Level 1 Level 2 Level 3 Total Financial Assets: Commodity derivative assets $ — $ 57,339 $ — $ 57,339 Financial Liabilities: Commodity derivative liabilities $ — $ 196 $ — $ 196 Fair Value Measurements at December 31, 2017 Using Level 1 Level 2 Level 3 Total Financial Assets: Commodity derivative assets $ — $ 4,132 $ — $ 4,132 Financial Liabilities: Commodity derivative liabilities $ — $ 84,702 $ — $ 84,702 The following methods and assumptions were used to estimate the fair value of the assets and liabilities in the table above: Commodity Derivative Instruments The Company determines its estimate of the fair value of derivative instruments using a market based approach that takes into account several factors, including quoted market prices in active markets, implied market volatility factors, quotes from third parties, the credit rating of each counterparty, and the Company’s own credit rating. In consideration of counterparty credit risk, the Company assessed the possibility of whether each counterparty to the derivative would default by failing to make any contractually required payments. Additionally, the Company considers that it is of substantial credit quality and has the financial resources and willingness to meet its potential repayment obligations associated with the derivative transactions. Derivative instruments utilized by the Company consist of swaps, put options, and call options. The oil and natural gas derivative markets are highly active. Although the Company’s derivative instruments are valued using public indices, the instruments themselves are traded with third‑party counterparties and are not openly traded on an exchange. As such, the Company has classified these instruments as Level 2. Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above) and long‑term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are representative of their fair values due to their short‑term maturities. The carrying amount of the Company’s credit facility approximated fair value as it bears interest at variable rates over the term of the loan. The fair value of the 2021 Senior Notes, 2024 Senior Notes and 2026 Senior Notes (collectively, the "Senior Notes") was derived from available market data. As such, the Company has classified the Senior Notes as Level 2. Please refer to Note 5 — Long‑Term Debt for further information. The Company’s policy is to recognize transfers between levels at the end of the period. This disclosure (in thousands) does not impact the Company’s financial position, results of operations or cash flows. At December 31, 2018 At December 31, 2017 Carrying Carrying Amount Fair Value Amount Fair Value Credit facility $ 285,000 $ 285,000 $ 90,000 $ 90,000 2021 Senior Notes (1) $ — $ — $ 540,382 $ 583,000 2024 Senior Notes (2) $ 393,866 $ 330,000 $ 392,979 $ 427,000 2026 Senior Notes (3) $ 738,793 $ 558,750 $ — $ — (1) The carrying amount of the 2021 Senior Notes includes unamortized debt issuance costs of $ 9.6 million as of December 31, 2017 . There were no unamortized debt issuance costs as of December 31, 2018 . (2) The carrying amount of the 2024 Senior Notes includes unamortized debt issuance costs of $6.1 million and $7.0 million as of December 31, 2018 and 2017 , respectively. (3) The carrying amount of the 2026 Senior Notes includes unamortized debt issuance costs of $11.2 million as of December 31, 2018 . There were no unamortized debt issuance costs as of December 31, 2017 . Non‑Recurring Fair Value Measurements The Company applies the provisions of the fair value measurement standard on a non‑recurring basis to its non‑financial assets and liabilities, including proved property and goodwill. These assets and liabilities are not measured at fair value on a recurring basis, but are subject to fair value adjustments when facts are circumstances arise that indicate a need for measurement. The Company utilizes fair value on a non‑recurring basis to review its proved oil and gas properties for potential impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of such property. The Company uses an income approach analysis based on the net discounted future cash‑flows of producing property. The future cash‑flows are based on Management’s estimates for the future. Unobservable inputs included future estimates of oil and gas production, as the case may be, from the Company’s reserve reports, commodity prices based on the sales contract terms or forward price curves, operating and development costs, and a discount rate based on a market-based weighted average cost of capital (all of which are Level 3 inputs within the fair value hierarchy). For the years ended December 31, 2018 and 2016 , the Company recognized $16.2 million and $22.5 million in impairment expense on proved oil and gas properties, respectively. The impairment expense for the years ended December 31, 2018 and 2016 is related to impairment of the assets in the Company’s northern field. The future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in the Company’s northern field. A portion of the net book value of these proved oil and gas properties were impaired at September 30, 2018 and the proved oil and gas properties in the northern field were written down to their fair value. The full net book value of these proved oil and gas properties were impaired at June 30, 2016 as it was determined that the proved oil and gas properties had no remaining fair value. No impairment expense was recognized for the year ended December 31, 2017 on proved oil and gas properties. The Company applies the provisions of ASC 350, Intangibles-Goodwill and Other . Goodwill represents the excess of the purchase price over the estimated value of the net assets acquired in business combinations. The Company tests goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test is performed at the reporting unit level, which represents the Company’s oil and gas operations in its core DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of the Company’s common shares could change the estimates of the fair value of the reporting unit and could result in an impairment charge. The Company performed a quantitative assessment as of September 30, 2018, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company identified triggering events as of December 31, 2018, due to the decrease in commodity pricing and the quoted market price of the Company's common shares compared to September 30, 2018. As such, the Company performed a quantitative assessment as of December 31, 2018 , utilizing an income approach based on estimates of the expected discounted future cash flows of the reporting unit's oil and gas properties, which concluded the fair value of the reporting unit was not greater than its carrying amount. As a result, the Company recorded goodwill impairment of $54.2 million , the entirety of the balance, for the year ended December 31, 2018 . The Company performed a quantitative assessment as of September 30, 2017, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company performed a qualitative assessment as of December 31, 2017 and 2016, which concluded the fair value of the reporting unit was more-likely-than-not greater than its carrying amount. The Company’s other non‑recurring fair value measurements include the purchase price allocations for the fair value of assets and liabilities acquired through business combinations, please refer to Note 4 — Acquisitions and Divestitures . The fair value of assets and liabilities acquired through business combinations is calculated using a discounted‑cash flow approach using level 3 inputs. Cash flow estimates require forecasts and assumptions for many years into the future for a variety of factors, including risk‑adjusted oil and gas reserves, commodity prices, development costs, and operating costs, based on market participant assumptions. The fair value of assets or liabilities associated with purchase price allocations is measured on a non‑recurring basis and is not measured in periods after initial recognition. |

Beginning on or after the later of (a) 90 days after the closing of the Offering and (b) the earlier of 120 days after the closing of the Offering and the expiration of the lock-up period contained in the underwriting agreement entered into in connection with the Offering ("Lock-Up Period End Date"), the Series A Preferred Stock will be convertible into shares of the Company's common stock at the election of the holders of the Series A Preferred Stock ("Series A Preferred Holders") at a conversion ratio per share of Series A Preferred Stock of 61.9195 . Beginning on or after the Lock-Up Period End Date until the three year anniversary of the closing of the Offering, the Company may elect to convert the Series A Preferred Stock at a conversion ratio per share of Series A Preferred Stock of 61.9195 , but only if the closing price of the Company’s common stock trades at or above a certain premium to the Company’s initial offering price, such premium to decrease with time. In accordance with ASC Topic 470, Debt ("ASC 470"), the Company determined that the conversion feature of the Series A Preferred Stock represented a beneficial conversion feature. The fair value of the Company's common stock on the closing of the IPO was greater than the Series A Preferred Stock conversion price by approximately $32.7 million in aggregate. Under ASC 470, $32.7 million (the fair value of the beneficial conversion feature) of the proceeds received from the issuance of the Series B Preferred Units, subsequently converted to the Series A Preferred Stock, was allocated to additional paid-in capital. The beneficial conversion feature is required to be accreted on a non-cash basis over the approximate 60 month period between the issuance date and the required redemption date of October 15, 2021, or fully accreted upon an accelerated date of redemption or conversion, resulting in an increase of the Series A Convertible Preferred Stock presented on the Consolidated Balance Sheets. The accretion of the beneficial conversion feature of Series A Preferred Stock is presented as a decrease to additional paid-in capital on the changes in members' and stockholders' equity and noncontrolling interest. As a result, approximately $6.0 million and $5.4 million was accreted during the years ended December 31, 2018 and 2017 . In certain situations, including a change of control, the Series A Preferred Stock may be redeemed for cash in an amount equal to the greater of (i) 135% of the liquidation preference of the Series A Preferred Stock and (ii) a 17.5% annualized internal rate of return on the liquidation preference of the Series A Preferred Stock. The Series A Preferred Stock mature on October 15, 2021, at which time they are mandatorily redeemable for cash at the liquidation preference. |

Income Taxes | Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted making significant changes to the Internal Revenue Code. Many of the provisions in the TCJA have an effective date for years beginning after December 31, 2017, including the lowering of the U.S. corporate rate from 35 percent to 21 percent. As a result, the Company was required to remeasure the deferred tax assets and liabilities as of December 31, 2017 at the rate in which they are expected to reverse. This re-measurement of deferred tax assets and liabilities required the Company to analyze and record a one-time adjustment to reduce the overall deferred tax liability in the consolidated balance sheets and reflect a corresponding income tax benefit in the consolidated statements of operations for the year ended December 31, 2017. This resulted in the recording of an income tax benefit of $23.4 million , as well as a corresponding reduction in the deferred tax liability as of December 31, 2017. During the third quarter of 2018, we completed the accounting for the income tax effect of the TCJA's limit on compensation under Internal Revenue Code Sec. 162(m) and stock-based compensation for covered employees. This resulted in a $0.4 million reduction in deferred tax assets that had been recorded as a provisional amount as of December 31, 2017 . The Company believes the accounting is complete regarding the revaluation of the deferred tax balances and there are no remaining provisional amounts associated with the TCJA as of December 31, 2018 . The Company is aware that the Internal Revenue Service has issued proposed regulations regarding the TCJA and has incorporated this guidance into its current tax policy. The Company will continue to monitor and analyze the impact of future guidance and any final regulations as they become available. The components of the income tax expense (benefit) were as follows (in thousands): For the Year Ended December 31, 2018 2017 Current: Federal $ — $ — State, net of federal benefit — — Total current income tax expense (benefit) $ — $ — Deferred: Federal $ 56,943 $ (61,719 ) State, net of federal benefit 9,907 (1,981 ) Total deferred income tax expense (benefit) $ 66,850 $ (63,700 ) Income tax expense (benefit) $ 66,850 $ (63,700 ) The following table reconciles the income tax expense (benefit) with income tax expense at the federal statutory rate (in thousands): For the Year Ended December 31, 2018 2017 Net income (loss) before income taxes $ 188,705 $ (108,108 ) Federal income taxes at statutory rate 39,628 (37,838 ) Impact of goodwill impairment 11,386 — State income taxes, net of federal benefit 9,907 (3,118 ) Nondeductible stock-based compensation 5,088 2,264 Enactment of the Tax Cuts and Jobs Act — (23,412 ) Other 841 (1,596 ) Income tax expense (benefit) 66,850 (63,700 ) Net income (loss) $ 121,855 $ (44,408 ) The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows (in thousands): As of December 31, 2018 2017 Deferred Tax Assets: Net operating loss carryforward $ 149,399 $ 205,806 Commodity derivatives — 19,984 Stock-based compensation 17,242 13,853 Intangible drilling costs - Section 59(e) 127,604 — Property taxes 22,277 12,667 Other 10,856 4,386 Total deferred tax assets $ 327,378 $ 256,696 Deferred Tax Liabilities: Excess basis of oil and gas properties $ (426,428 ) $ (299,022 ) Commodity derivatives (10,126 ) — Total deferred tax liabilities (436,554 ) (299,022 ) Deferred Tax Liability, net $ (109,176 ) $ (42,326 ) Management considers whether some portion or all of the deferred tax assets will be realized based on a more likely than not standard of judgment. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. The Company has net operating loss carryforwards (NOLs) for U.S. income tax purposes that have been generated from the Company's operations in 2017 of approximately $605.9 million , which expire in 2037 and are not subject to the 80 percent limitation of taxable income. As of December 31, 2018, the Company also had $517.5 million of indirect drilling costs that were capitalized under Code Section 59(e). As of December 31, 2017, the Company had no indirect drilling costs that were capitalized under Code Section 59(e). The utilization of such NOL carryforwards may be limited upon the occurrence of certain ownership changes as stipulated in Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"). As of December 31, 2018, the Company determined that the statutory provision of Section 382 will not limit the Company’s ability to realize future tax benefits. As of December 31, 2018, the Company believes it will be able to generate sufficient future taxable income and accordingly, believes that it is more likely than not that its deferred income tax assets will be fully realized. The Company files income tax returns in the U.S. federal jurisdiction and in Colorado. The statute of limitations related to the 2016 and 2017 tax returns are open through 2020 and 2021 respectively, however, the ability for the tax authority to adjust the NOL will continue until three years after the NOL is utilized. As of December 31, 2018 , the Company believes that it has no liability for uncertain tax positions. If the Company were to determine there were any uncertain tax positions, the Company would recognize the liability and related interest and penalties within income tax expense. As of December 31, 2018 , the Company had no provision for interest or penalties related to uncertain tax positions. |

Unit and Stock-Based Compensation | Unit and Stock-Based Compensation Extraction Long Term Incentive Plan In October 2016, the Board of Directors adopted the Extraction Oil & Gas, Inc. 2016 Long Term Incentive Plan (the “2016 Plan” or “LTIP”), pursuant to which employees, consultants, and directors of the Company and its affiliates performing services for the Company are eligible to receive awards. The 2016 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, bonus stock, dividend equivalents, other stock-based awards, substitute awards, annual incentive awards, and performance awards intended to align the interests of participants with those of stockholders. In accordance with the terms of the LTIP, 20.2 million shares of common stock have been reserved for issuance pursuant to awards under the LTIP. Extraction has granted awards under the LTIP to certain directors, officers and employees, including stock options, restricted stock units and performance stock awards. Restricted Stock Units (“RSUs”) Restricted stock units granted under the LTIP (“RSUs”) vest over either (i) a one -year service period, with 100% of the units vesting at the end of the service period, or (ii) a three -year service period with 25% , 25% and 50% of the units vesting in year one , two and three , respectively. Grant date fair value was determined based on the value of Extraction’s common stock on the date of issuance. The Company assumed a forfeiture rate of zero as part of the grant date estimate of compensation cost. As of January 1, 2017, the Company elected to account for stock-based compensation forfeitures as they occur, as a result of the adoption of ASU No. 2016-09. The Company recorded $27.9 million , $31.8 million and $5.5 million of stock-based compensation costs related to RSUs for the years ended December 31, 2018 , 2017 and 2016 , respectively. As of December 31, 2018 , there was $32.2 million of total unrecognized compensation cost related to the unvested RSUs granted to certain employees that is expected to be recognized over a weighted average period of 1.4 years . The following table summarizes the RSU activity from January 1, 2016 through December 31, 2018 and provides information for RSUs outstanding at the dates indicated.

The fair value of the stock options was measured at the grant date using the Black Scholes valuation model. The Company utilizes the "simplified" method to estimate the expected term of the stock options granted as there is limited historical exercise data available in estimating the expected term of the stock options. Expected volatility is based on the volatility of the historical stock prices of the Company’s peer group. The risk-free rates are based on the yields of U.S. Treasury instruments with comparable terms. A dividend yield and forfeiture rate of zero were assumed. Stock options granted under the LTIP vest ratably over three years and are exercisable immediately upon vesting through the tenth anniversary of the grant date. To fulfill options exercised, the Company issues new shares. The Company recorded $15.1 million , $15.7 million and $2.9 million of stock-based compensation costs related to the stock options for the years ended December 31, 2018 , 2017 and 2016 , respectively. As of December 31, 2018 , there was $12.1 million of unrecognized compensation cost related to the stock options that is expected to be recognized over a weighted-average period of 0.8 years . The following table summarizes the assumptions used for the Black-Scholes valuation model to calculate the stock-based compensation expense for the years ended December 31, 2017 and 2016 .

The number of shares of the Company's common stock that may be issued to settle PSAs ranges from zero to one times the number of PSAs awarded. Generally, the shares issued for PSAs are determined based on the satisfaction of a time-based vesting schedule and a weighting of one or more of the following: i) absolute total stockholder return ("ATSR"), ii) relative total stockholder return ("RTSR"), as compared to the Company's peer group and iii) cash return on capital invested ("CROCI") measured over a three-year period and vest in their entirety at the end of the three-year measurement period. Any PSAs that have not vested at the end of the applicable measurement period are forfeited. The vesting criterion that is associated with the RTSR is based on a comparison of the Company's total shareholder return for the measurement period compared to that of a group of peer companies for the same measurement period. As the ATSR and RTSR vesting criteria are linked to the Company's share price, they each are considered a market condition for purposes of calculating the grant-date fair value of the awards. The vesting criterion that is associated with the CROCI is considered a performance condition for purposes of calculating the grant-date fair value of the awards. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. A stochastic process is a mathematically defined equation that can create a series of outcomes over time. Those outcomes are not deterministic in nature, which means that by iterating the equations multiple times, different results will be obtained for those iterations. In the case of the Company's PSAs, the Company cannot predict with certainty the path its stock price or the stock prices of its peer will take over the performance period. By using a stochastic simulation, the Company can create multiple prospective stock pathways, statistically analyze these simulations, and ultimately make inferences regarding the most likely path the stock price will take. As such, because future stock prices are stochastic, or probabilistic with some direction in nature, the stochastic method, specifically the Monte Carlo Model, is deemed an appropriate method by which to determine the fair value of the PSAs. Significant assumptions used in this simulation include the Company's expected volatility, risk-free interest rate based on U.S. Treasury yield curve rates with maturities consistent with the measurement period as well as the volatilities for each of the Company's peers. The assumptions used in valuing the PSAs granted were as follows: For the Year Ended For the Year Ended December 31, 2018 December 31, 2017 Risk free rates 2.3 % 1.5 % Dividend yield — — Expected volatility 59.9 % 45.0 % The Company recorded $5.7 million and $0.8 million of stock-based compensation costs related to PSAs for the years ended December 31, 2018 and 2017 , respectively. The Company did not record any stock-based compensation expense related to PSAs for the year ended December 31, 2016 . As of December 31, 2018 , there was $9.1 million of unrecognized compensation cost related to the PSAs that is expected to be recognized over a weighted-average period of 1.7 year. The following table summarizes the PSA activity from January 1, 2017 through December 31, 2018 and provides information for PSAs outstanding at the dates indicated. Weighted Average Number of Grant Date Shares (1) Fair Value Non-vested PSAs as of January 1, 2017 — $ — Granted 832,163 $ 8.85 Forfeited — $ — Vested — $ — Non-vested PSAs as of December 31, 2017 832,163 $ 8.85 Granted 1,961,920 $ 9.06 Forfeited — $ — Vested — $ — Non-vested PSAs as of December 31, 2018 2,794,083 $ 9.00 (1) The number of awards assumes that the associated maximum vesting condition is met at the target amount. The final number of shares of the Company's common stock issued may vary depending on the performance multiplier, which ranges from zero to one, depending on the level of satisfaction of the vesting condition. Incentive Restricted Stock Units (“Incentive RSUs”) Officers of the Company contributed 2.7 million shares of common stock to Extraction Employee Incentive, LLC (“Employee Incentive”), which is owned solely by certain officers of the Company. Employee Incentive issued restricted stock units (“Incentive RSUs”) to certain employees. Incentive RSUs vest over a three -year service period, with 25% , 25% and 50% of the units vesting in year one , two and three , respectively. On July 10, 2017, the partners of Employee Incentive amended the vesting schedule in which 25% vested on July 17, 2017 and the remaining Incentive RSUs will vest 25% , 25% and 25% each six months thereafter, over the remaining 18 months service period. Grant date fair value was determined based on the value of Extraction’s common stock on the date of issuance. The Company assumed a forfeiture rate of zero as part of the grant date estimate of compensation cost. As of January 1, 2017, the Company elected to account for stock-based compensation forfeitures as they occur, as a result of the adoption of ASU No. 2016-09. As the vesting of any Incentive RSUs will be satisfied with shares of common stock that are already issued and outstanding, the Incentive RSUs do not have any impact on the Company’s diluted earnings per share calculation. The Company recorded $19.6 million , $17.3 million and $2.4 million of stock-based compensation costs related to Incentive RSUs for the years ended December 31, 2018 , 2017 and 2016 , respectively. These costs were included in the consolidated statements of operations within the general and administrative expenses line item. As of December 31, 2018 , there was $0.9 million of total unrecognized compensation cost related to the unvested Incentive RSUs granted to certain employees that is expected to be recognized over a weighted average period of 0.1 years . The following table summarizes the Incentive RSU activity from January 1, 2016 through December 31, 2018 and provides information for Incentive RSUs outstanding at the dates indicated. Weighted Average Number of Grant Date Shares Fair Value Non-vested Incentive RSUs at January 1, 2016 — $ — Granted 2,717,968 $ 20.45 Forfeited (3,600 ) $ 20.45 Vested — $ — Non-vested Incentive RSUs at December 31, 2016 2,714,368 $ 20.45 Granted — $ — Forfeited (710,993 ) $ 20.45 Vested (507,200 ) $ 20.45 Non-vested Incentive RSUs at December 31, 2017 1,496,175 $ 20.45 Granted — $ — Forfeited (41,400 ) $ 20.45 Vested (978,775 ) $ 20.45 Non-vested Incentive RSUs at December 31, 2018 476,000 $ 20.45 Holdings’ Membership Unit Incentive Plan On May 29, 2014, Holdings adopted the 2014 Membership Unit Incentive Plan (“2014 Plan”). The 2014 Plan provided for the compensation of employees, non‑employee managers and consultants of the Company and its affiliates through grants of restricted unit awards (“Holdings’ RUAs”) and incentive units (“Holdings’ Incentive Units”). The 2014 Plan was terminated as a result of the Corporate Reorganization in October 2016. Holdings’ RUAs Holdings’ RUAs vested over a three ‑year service period, with 25% , 25% and 50% of the units vesting in year one, two and three, respectively. The Company estimated fair value of the RUAs on their grant date based upon estimated volatility, market comparable risk free rate, estimated forfeiture rate and a discount for lack of marketability. Grant date fair value was determined based on the value of Holdings’ Equity Units on the date of the grant. Due to a lack of historical data, the Company used the experience of other entities in the same industry to estimate a forfeiture rate. Expected forfeitures are then included as part of the grant date estimate of compensation cost. No unit-based compensation costs related to Holdings' RUA grants were recorded for December 31, 2018 and 2017 . The Company recorded $16.8 million of unit-based compensation costs related to Holdings’ RUA grants for the year ended December 31, 2016 . These costs are included in the consolidated statements of operations within the general and administrative expenses line item. In connection with the Corporate Reorganization in 2016, the Holdings Membership Unit Incentive Plan ("2014 Plan") was terminated. As of December 31, 2018 , there is no unrecognized compensation cost related to unvested RUAs granted to employees. The following table summarizes the Holdings’ RUA activity from January 1, 2016 through December 31, 2016 and provides information for Holdings’ RUAs outstanding at the dates indicated. Weighted Average Number of Grant Date Shares Fair Value Non-vested RUAs at January 1, 2016 6,311,242 $ 2.23 Granted 1,531,542 $ 5.84 Forfeited (181,817 ) $ 2.68 Vested (7,660,967 ) $ 2.94 Non-vested RUAs at December 31, 2016 — $ — PRL RUAs PRL granted RUAs to certain employees, including Extraction employees (“PRL RUAs”). PRL RUAs vested over a three years service period, with 25% , 25% and 50% of the units vesting in year one, two and three, respectively. Grant date fair value was determined based on the value of PRL’s Equity Units on the date of the grant. PRL uses its past experience to estimate a forfeiture rate and expected forfeitures are included as part of the grant date estimate of compensation cost. No unit-based compensation costs related to PRL RUA grants were recorded for the year ended December 31, 2018 and 2017 . The Company recorded $0.5 million of unit-based compensation costs related to PRL RUA grants for the year ended December 31, 2016 . These costs are included in the consolidated statements of operations within the general and administrative expenses line item. In connection with the Corporate Reorganization in 2016, the Holdings Membership Unit Incentive Plan ("2014 Plan") was terminated. As of December 31, 2018 , there was no unrecognized compensation cost related to the PRL RUAs as all awards were fully vested. Holdings’ Incentive Units In accordance with the 2014 Plan and the Holdings LLC Agreement, Holdings issued 3.0 million Holdings’ incentive units to certain members of management in the fourth quarter of 2015. All of Holdings’ Incentive Units were non‑voting and subject to certain vesting and performance conditions. The Holdings’ Incentive Units vested over a three year service period, with 25% , 25% and 50% of the units vesting in year 1, year 2 and year 3, respectively (with vesting between the first and third anniversaries occurring pro-rata based on the number of full months elapsed since the last vesting date), and in full upon a change of control, as defined in the Holdings LLC Agreement. The Holdings’ Incentive Units were accounted for as liability awards under ASC 718, Compensation-Stock Compensation , with compensation expense based on period‑end fair value. In connection with the IPO, the Board of Managers of Holdings accelerated the vesting of the Holdings’ Incentive Units. The Company’s IPO and change of control triggered the conversion of these units into approximately 9.1 million common shares of the Company based on the 10 -day volume weighted average price of the Company’s common stock following its IPO as set forth in the Holdings Third Amended and Restated LLC Agreement. For the year ended December 31, 2016 , the Company recognized approximately $172.1 million in non-cash, stock-based compensation expense in connection with the conversion of the Holdings’ Incentive Units into the Company’s common stock. As of December 31, 2018 and 2017 , there was no unrecognized compensation cost related to the Holdings' Incentive Units. |

Earnings Per Share [Abstract] | |
Earnings (Loss) per Share | Earnings (Loss) Per Share Basic earnings per share (“EPS”) includes no dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of shares outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in the earnings available to common shareholders of the Company. The Company uses the “if-converted” method to determine potential dilutive effects of Series A Preferred Stock and the treasury method to determine the potential dilutive effects of outstanding restricted stock awards and stock options. EPS for the year ended December 31, 2016 is calculated for the period from October 12, 2016, the effective date of the Corporate Reorganization, to December 31, 2016. EPS information is not applicable for reporting periods prior to the Corporate Reorganization. The basic weighted average shares outstanding calculation is based on the actual days in which the shares were outstanding for the period from October 12, 2016 to December 31, 2016. Please refer to Note 1 — Business and Organization and Note 9 — Equity for additional discussion regarding the Corporate Reorganization. The components of basic and diluted EPS were as follows: Year Ended December 31, 2018 Year Ended December 31, 2017 From October 12, 2016 to December 31, 2016 Basic and Diluted EPS (in thousands, except per share data) Net income (loss) $ 121,855 $ (44,408 ) $ (226,107 ) Less: Noncontrolling interest (7,287 ) — — Less: Adjustment to reflect Series A Preferred Stock dividend (10,885 ) (10,885 ) (2,958 ) Less: Adjustment to reflect accretion of Series A Preferred Stock discount (5,984 ) (5,394 ) (1,041 ) Net income (loss) available to common shareholders, basic and diluted $ 97,699 $ (60,687 ) $ (230,106 ) Weighted Average Common Shares Outstanding (1) (2) (3) Basic and diluted 174,748 171,910 149,029 Net Income (Loss) Allocated to Common Shareholders per Common Share Basic and diluted $ 0.56 $ (0.35 ) $ (1.54 ) (1) For the year ended December 31, 2018 , 3,102,335 potentially dilutive shares associated with restricted stock awards outstanding were not included in the calculation above, as they had an anti-dilutive effect on EPS. Additionally, 5,244,428 common shares for stock options were excluded as they were out-of-the-money and 11,472,445 common shares associated with the assumed conversion of Series A Preferred Stock were also excluded, as they would have had an anti-dilutive effect on EPS.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Leases The Company leases two office spaces in Denver, Colorado, two office spaces in Greeley, Colorado and one office space in Houston, Texas under separate operating lease agreements. The Denver, Colorado leases expire on February 29, 2020 and May 31, 2028, respectively. The Greeley and Houston leases expire on October 31, 2019, June 30, 2019 and January 31, 2022, respectively. Total rental commitments under non-cancelable leases for office space were $32.8 million at December 31, 2018 . The future minimum lease payments under these non-cancelable leases are as follows: $3.5 million in 2019 , $3.4 million in 2020 , $3.4 million in 2021 , $3.4 million in 2022 , $3.4 million in 2023 and $15.7 million thereafter. Rent expense was $3.4 million , $2.3 million , and $1.9 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. On June 4, 2015, the Company subleased the remaining term of one of its Denver office leases that expires February 29, 2020. The sublease will decrease the Company’s future lease payments by $0.3 million . Drilling Rigs As of December 31, 2018 , the Company was subject to commitments on three drilling rigs. In the event of early termination of these contracts, the Company would be obligated to pay an aggregate amount of approximately $9.2 million as of December 31, 2018 , as required under the terms of the contracts. In February 2016, the Company provided notice to terminate one of its drilling rigs that was subject to commitment at December 31, 2015. As part of this termination, the Company was obligated to pay $1.0 million in the second quarter of 2016, which was recorded in the consolidated statements of operations within the other operating expenses line item. In January 2017, the Company provided notice for termination on one drilling rig and paid no termination fees. Delivery Commitments As of December 31, 2018 , the Company’s oil marketer is subject to a firm transportation agreement that commenced in November 2016 and has a ten -year term with a monthly minimum delivery commitment of 45,000 Bbl/d in year one, 55,800 Bbl/d in year two, 61,800 Bbl/d in years three through seven and 58,000 Bbl/d in years eight through ten. In May 2017, the Company amended its agreement with its oil marketer that requires it to sell all of its crude oil from an area of mutual interest in exchange for a make-whole provision that allows the Company to satisfy any minimum volume commitment deficiencies incurred by its oil marketer with future barrels of crude oil in excess of their minimum volume commitment through October 31, 2018. In December 2017, the Company extended the term of this agreement through October 31, 2019 and has posted a letter of credit in the amount of $35.0 million . The Company is currently in the process of amending and extending this agreement. The Company evaluates its contracts for loss contingencies and accrues for such losses, if the loss can be reasonably estimated and deemed probable. The Company also has two long-term crude oil gathering commitments with an unconsolidated subsidiary, in which the Company has a minority ownership interest. The first agreement commenced in November 2016 and has a term of ten years with a minimum volume commitment of an average 9,167 Bbl/d in year one, 17,967 Bbl/d in year two, 18,800 Bbl/d for years three through five and 10,000 Bbl/d for years six through ten. The second agreement will commence in or around July 2019 and has a term of ten years for an average of 3,200 Bbl/d in year one, 8,000 Bbl/d in year two, 14,000 Bbl/d in year three, 16,000 Bbl/d in years four through eight, 12,000 Bbl/d in year nine and 10,000 Bbl/d in year ten. The remaining aggregate amount of estimated payments under these agreements is approximately $875.8 million . In collaboration with several other producers and a midstream provider, on December 15, 2016 and August 7, 2017, the Company agreed to participate in expansions of natural gas gathering and processing capacity in the DJ Basin. The plan includes two new processing plants as well as the expansion of related gathering systems. The first plant commenced operations in August 2018 and the second plant is expected to be completed by mid-2019, although the exact start-up date is undetermined at this time. The Company’s share of these commitments will require 51.5 MMcf and 20.6 MMcf per day, respectively, to be delivered after the plants' in-service dates for a period of seven years thereafter. The Company may be required to pay a shortfall fee for any volumes under these commitments. These contractual obligations can be reduced by the Company’s proportionate share of the collective volumes delivered to the plants by other third party incremental volumes available to the midstream provider at the new facilities that are in excess of the total commitments. The Company is also required for the first three years of each contract to guarantee a certain target profit margin on these volumes sold. Under its current drilling plans, the Company expects to meet these volume commitments. In February 2019, the Company entered into two long-term gas gathering agreements with third-party midstream providers. The first agreement will commence in or around November 2019 and has a term of twenty years with a minimum volume commitment of 251 Bcf to be delivered within the first seven years. The annual commitments over seven years are to be delivered on an average 48,000 Mcf/d in year one, 96,000 Mcf/d in year two, 132,000 Mcf/d in year three, 120,000 Mcf/d in year four, 108,000 Mcf/d in year five, 104,000 Mcf/d in year six and 80,000 Mcf/d in year seven. The aggregate amount of estimated payments under this agreement is approximately $317.7 million . The second agreement will commence in or around January 2020 and has a term of ten years with an annual minimum volume commitment of 13.0 Bcf in years one through ten. The Company may be required to pay an annual shortfall fee for any volume deficiencies under this commitment, calculated based on the weighted average sales price during the corresponding annual period. Under its current drilling plans, the Company expects to meet these volume commitments. Acquisition of Undeveloped Leasehold Acreage The Company was party to an agreement during 2017 with an unrelated third party for which it has paid $247.6 million through December 31, 2018 to complete its leasing program of approximately 38,800 net acres of undeveloped leasehold. General The Company is subject to contingent liabilities with respect to existing or potential claims, lawsuits, and other proceedings, including those involving environmental, tax, and other matters, certain of which are discussed more specifically below. The Company accrues liabilities when it is probable that future costs will be incurred and such costs can be reasonably estimated. Such accruals are based on developments to date and the Company’s estimates of the outcomes of these matters and its experience in contesting, litigating, and settling other matters. As the scope of the liabilities becomes better defined, there will be changes in the estimates of future costs, which management currently believes will not have a material effect on the Company’s financial position, results of operations, or cash flows. As is customary in the oil and gas industry, the Company may at times have commitments in place to reserve or earn certain acreage positions or wells. If the Company does not meet such commitments, the acreage positions or wells may be lost or the Company may be required to pay damages if certain performance conditions are not met. Legal Matters From time to time, the Company is party to ongoing legal proceedings in the ordinary course of business. While the outcome of these proceedings cannot be predicted with certainty, the Company does not believe the results of these proceedings, individually or in the aggregate, will have a material adverse effect on the Company's business, financial condition, results of operations or liquidity. |

All reserves are located within the DJ Basin. Proved oil, natural gas and NGL reserves are the estimated quantities of oil, natural gas and NGL which geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions (i.e., prices and costs) existing at the time the estimate is made. Proved developed oil, natural gas and NGL reserves are proved reserves that can be expected to be recovered through existing wells and equipment in place and under operating methods being utilized at the time the estimates were made. The principal methodologies employed are decline curve analysis and analogy. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and gas properties. Accordingly, these estimates are expected to change as future information becomes available. The following table sets forth information for the years ended December 31, 2018 , 2017 and 2016 with respect to changes in the Company’s proved (i.e. proved developed and undeveloped) reserves: Crude Oil Natural Gas NGL MBoe Mbbls MMcf Mbbls Total Balance as of December 31, 2015 71,500.2 292,583.9 38,382.9 158,647.1 Revisions of previous estimates (15,576.8 ) 35,803.1 1,988.8 (7,620.8 ) Purchase of reserves 18,473.6 78,761.6 9,680.7 41,281.2 Extensions, discoveries, and other additions 21,885.4 120,798.3 14,679.9 56,698.5 Sale of reserves — — — — Production (5,287.4 ) (20,211.5 ) (2,284.0 ) (10,940.0 ) Balance as of December 31, 2016 90,995.0 507,735.4 62,448.3 238,066.0 Revisions of previous estimates (625.9 ) 9,349.8 1,961.6 2,894.0 Purchase of reserves 10,761.2 11,183.6 1,563.3 14,188.3 Extensions, discoveries, and other additions 19,738.4 130,295.4 15,033.6 56,487.9 Sale of reserves — — — — Production (9,593.7 ) (32,395.2 ) (3,900.8 ) (18,893.7 ) Balance as of December 31, 2017 111,275.0 626,169.0 77,106.0 292,742.5 Revisions of previous estimates 6,264.3 (49,239.2 ) (1,382.9 ) (3,325.1 ) Purchase of reserves 6,296.3 24,667.8 3,264.4 13,672.0 Extensions, discoveries, and other additions 32,475.3 164,424.0 22,853.4 82,732.7 Sale of reserves (5,786.1 ) (15,906.5 ) (1,730.0 ) (10,167.2 ) Production (14,679.3 ) (46,846.6 ) (5,260.1 ) (27,747.2 ) Balance as of December 31, 2018 135,845.5 703,268.5 94,850.8 347,907.7 Proved Developed Reserves, included above Balance as of December 31, 2016 17,158.0 107,918.0 13,354.0 48,498.4 Balance as of December 31, 2017 37,078.0 222,236.0 27,932.0 102,049.2 Balance as of December 31, 2018 47,075.0 316,499.0 39,689.0 139,514.0 Proved Undeveloped Reserves, included above Balance as of December 31, 2016 73,837.0 399,817.4 49,094.3 189,567.5 Balance as of December 31, 2017 74,197.0 403,933.0 49,174.0 190,693.2 Balance as of December 31, 2018 88,771.0 386,769.0 55,162.0 208,395.0 • The values for the 2018 oil, natural gas and NGL reserves are based on the 12-month arithmetic average of the first day of the month prices for the period from January through December 31, 2018 . The unweighted arithmetic average first-day-of-the-month prices for the prior twelve months were $65.56 per barrel (West Texas Intermediate price) for crude oil and NGL and $3.10 per MMBtu (Henry Hub price) for natural gas. All prices are then further adjusted for transportation, quality and basis differentials. The average resulting price used as of December 31, 2018 was $57.65 per barrel for oil, $1.47 per Mcf for natural gas and $20.45 per barrel for NGL. • The values for the 2017 oil, natural gas and NGL reserves are based on the 12-month arithmetic average of the first day of the month prices for the period from January through December 31, 2017 . The unweighted arithmetic average first-day-of-the-month prices for the prior twelve months were $51.34 per barrel (West Texas Intermediate price) for crude oil and NGL and $2.98 per MMBtu (Henry Hub price) for natural gas. All prices are then further adjusted for transportation, quality and basis differentials. The average resulting price used as of December 31, 2017 was $42.89 per barrel for oil, $1.73 per Mcf for natural gas and $20.28 per barrel for NGL. • The values for the 2016 oil, natural gas and NGL reserves are based on the 12-month arithmetic average of the first day of the month prices for the period from January through December 31, 2016 . The unweighted arithmetic average first-day-of-month prices for the prior twelve months were $42.75 per barrel (West Texas Intermediate price) for crude oil and NGL and $2.49 per MMBtu (Henry Hub price) for natural gas. All prices are then further adjusted for transportation, quality and basis differentials. The average resulting price used as of December 31, 2016 was $34.91 per barrel for oil, $1.39 per Mcf for natural gas and $11.63 per barrel for NGL. For the year ended December 31, 2018 , the Company had downward revisions of previous estimates of 3,325.1 MBoe. As a result of ongoing drilling and completion activities during 2018 , the Company reported extensions, discoveries, and other additions of 82,732.7 MBoe. Additionally, during 2018 the Company sold reserves of 10,167.2 MBoe and purchased reserves of 13,672.0 MBoe. For the year ended December 31, 2017 , the Company had upward revisions of previous estimates of 2,894.0 MBoe. As a result of ongoing drilling and completion activities during 2017 , the Company reported extensions, discoveries, and other additions of 56,487.9 MBoe. Additionally, during 2017 the Company purchased reserves of 14,188.3 MBoe. For the year ended December 31, 2016 , the Company had downward revisions of previous estimates of 7,620.8 MBoe. As a result of ongoing drilling and completion activities during 2016 , the Company reported extensions, discoveries, and other additions of 56,698.5 MBoe. Additionally, during 2016 the Company purchased reserves of 41,281.2 MBoe. Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil, Natural Gas and NGL Reserves The Company follows the guidelines prescribed in ASC 932, Extractive Activities-Oil and Gas for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. The following summarizes the policies used in the preparation of the accompanying oil, natural gas and NGL reserve disclosures, standardized measures of discounted future net cash flows from proved oil, natural gas and NGL reserves and the reconciliations of standardized measures from year to year. The information is based on estimates of proved reserves attributable to the Company’s interest in oil and gas properties as of December 31 of the years presented. These estimates were prepared by Ryder Scott Company L.P., independent petroleum engineers. The standardized measure of discounted future net cash flows from production of proved reserves was developed as follows: (1) Estimates are made of quantities of proved reserves and future periods during which they are expected to be produced based on year-end economic conditions. (2) The estimated future cash flows are compiled by applying the trailing twelve-month average of the first of the month prices applied to the Company’s proved reserve year-end quantities. (3) The future cash flows are reduced by estimated production costs, costs to develop and produce the proved reserves and abandonment costs, all based on year-end economic conditions, plus Company overhead incurred. (4) Future net cash flows are discounted to present value by applying a discount rate of 10% . The assumptions used to compute the standardized measure are those prescribed by the FASB and the SEC. These assumptions do not necessarily reflect the Company’s expectations of actual revenues to be derived from those reserves, nor their present value. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations, since these reserve quantity estimates are the basis for the valuation process. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established proved producing oil and gas properties. The standardized measure of discounted future net cash flows does not purport, nor should it be interpreted, to present the fair value of the Company’s oil and natural gas reserves. An estimate of fair value would also take into account, among other things, the recovery of reserves not presently classified as proved, anticipated future changes in prices and costs and a discount factor more representative of the time value of money and the risks inherent in reserve estimates. The following summary sets forth the Company’s future net cash flows relating to proved oil, natural gas and NGL reserves based on the standardized measure prescribed in ASC 932, Extractive Activities-Oil and Gas (in thousands): For the Year Ended December 31, 2018 2017 2016 Future crude oil, natural gas and NGL sales $ 10,805,063 $ 7,422,335 $ 4,610,848 Future production costs (3,215,840 ) (2,227,370 ) (1,429,202 ) Future development costs (1,912,641 ) (1,662,859 ) (1,579,628 ) Future income tax expense (694,398 ) (212,923 ) (42,859 ) Future net cash flows $ 4,982,184 $ 3,319,183 $ 1,559,159 10% annual discount (2,082,201 ) (1,440,177 ) (836,163 ) Standardized measure of discounted future net cash flows (1) $ 2,899,983 $ 1,879,006 $ 722,996 (1) For the years ended December 31, 2018 , 2017 and 2016 , future income tax expenses in the Company’s calculation of the standardized measure of discounted future net cash flows are based on year-end statutory tax rates giving effect to the remaining tax basis in the oil and gas properties, other deductions, credit and allowances relating to the Company’s proved reserves. For purposes of the standardized measure calculation, it was assumed that all of the Company’s operations are attributable to the Company’s oil and gas assets. The following are the principal sources of change in the standardized measure (in thousands): For the Year Ended December 31, 2018 2017 2016 Balance at beginning of period $ 1,879,006 $ 722,996 $ 835,883 Sales of crude oil, natural gas and NGL, net (851,574 ) (441,623 ) (195,316 ) Net change in prices and production costs 902,762 586,271 (325,236 ) Net change in future development costs (174,112 ) 3,959 (49,213 ) Extensions and discoveries 629,304 330,160 96,982 Acquisitions of reserves 88,124 59,745 156,675 Sale of reserves (55,042 ) — — Revisions of previous quantity estimates 132,373 188,421 19,161 Previously estimated development costs incurred 306,546 331,550 123,085 Net changes in income taxes (253,044 ) (79,181 ) (17,611 ) Accretion of discount 197,580 74,061 83,588 Changes in production timing and other 98,060 102,647 (5,002 ) Balance at end of period $ 2,899,983 $ 1,879,006 $ 722,996 |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation The consolidated financial statements include the accounts of the Company, including its wholly‑owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The financial statements included herein were prepared from the records of the Company in accordance with generally accepted accounting principles in the United States (“GAAP”). In the opinion of management, all adjustments, consisting primarily of normal recurring accruals that are considered necessary for a fair statement of the consolidated financial information, have been included. |
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of assumptions, judgments and estimates include (1) oil and gas reserves; (2) cash flow estimates used in impairment testing of oil and gas properties and goodwill; (3) depreciation, depletion, amortization and accretion; (4) asset retirement obligations; (5) assigning fair value and allocating purchase price in connection with business combinations, including the determination of any resulting goodwill; (6) accrued revenue and related receivables; (7) valuation of commodity derivative instruments; (8) accrued liabilities; (9) valuation of unit and stock-based payments, and (10) income taxes. Although management believes these estimates are reasonable, actual results could differ from these estimates. The Company evaluates its estimates on an on‑going basis and bases its estimates on historical experience and on various other assumptions the Company believes to be reasonable under the circumstances. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of all highly liquid investments that are readily convertible into cash and have original maturities of three months or less when purchased. |
Cash Held in Escrow | Cash Held in Escrow Cash held in escrow includes deposits for the purchase of certain oil and gas properties as required under the related purchase and sale agreements. |
Accounts Receivable | Accounts Receivable The Company records estimated oil and gas revenue receivable from third parties at its net revenue interest. The Company also reflects costs incurred on behalf of joint interest partners in accounts receivable. The Company generally has the ability to withhold future revenue disbursements to recover non‑payment of joint interest billings. On an on‑going basis, management reviews accounts receivable amounts for collectability and records its allowance for uncollectible receivables under the specific identification method. The Company did not record any allowance for uncollectible receivables as of or for the years ended December 31, 2018 and 2017 . |
Credit Risk and Other Concentrations | Credit Risk and Other Concentrations The Company’s cash and cash equivalents are exposed to concentrations of credit risk. The Company manages and controls this risk by investing these funds with major financial institutions. The Company often has balances in excess of the federally insured limits. The Company sells oil, natural gas and NGL to various types of customers, including oil marketers, pipelines and refineries. Credit is extended based on an evaluation of the customer’s financial conditions and historical payment record. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside the Company’s control, none of which can be predicted with certainty. For the three years ended December 31, 2018 , the Company had the following customers that exceeded 10% of total oil, natural gas and NGL revenues. The Company does not believe the loss of any single purchaser would materially impact its operating results because crude oil, natural gas and NGL are fungible products with well‑established markets and numerous purchasers. For the Year Ended December 31, 2018 2017 2016 Customer A 76 % 65 % 25 % Customer B 11 % 19 % 19 % Customer C — % 11 % — % Customer D — % — % 23 % Customer E — % — % 16 % At December 31, 2018 , the Company had commodity derivative contracts with eleven counterparties, all of whom are lenders under our credit agreement. The Company does not require collateral or other security from counterparties to support derivative instruments; however, to minimize the credit risk in derivative instruments, it is the Company’s policy to enter into derivative contracts only with counterparties that are credit worthy financial institutions deemed by management as competent and competitive market‑makers. Additionally, the Company uses master netting agreements to minimize credit‑risk exposure. The credit worthiness of the Company’s counterparties is subject to periodic review. For the years ended December 31, 2018 , 2017 and 2016 , the Company did not incur any losses with respect to counterparty contracts. None of the Company’s existing derivative instrument contracts contains credit‑risk related contingent features. |
Inventory and Prepaid Expenses | Inventory and Prepaid Expenses The Company records well equipment inventory at the lower of cost or net realizable value. Prepaid expenses are recorded at cost. Inventory and prepaid expenses are comprised of the following (in thousands): As of December 31, 2018 2017 Well equipment inventory $ 19,916 $ 9,971 Prepaid expenses 6,900 3,046 $ 26,816 $ 13,017 |
Oil and Gas Properties | Oil and Gas Properties The Company follows the successful efforts method of accounting for oil and gas properties. Under this method of accounting, all property acquisition costs and development costs are capitalized when incurred and depleted on a units‑of‑production basis over the remaining life of proved reserves and proved developed reserves, respectively. For the years ended December 31, 2018 , 2017 and 2016 , the Company excluded $144.3 million , $127.4 million and $98.7 million of capitalized costs from depletion related to wells in progress, respectively. For the years ended December 31, 2018 , 2017 and 2016 , the Company recorded depletion expense on capitalized oil and gas properties of $426.8 million , $306.7 million and $197.4 million , respectively. The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Costs incurred for exploratory wells that find reserves that cannot yet be classified as proved are capitalized if (a) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (b) sufficient progress in assessing the reserves and the economic and operating viability of the project has been made. The status of suspended well costs is monitored continuously and reviewed at each period end. Due to the capital‑intensive nature and the geological characteristics of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination of its commercial viability. As of December 31, 2018 , the Company had approximately $6.1 million of suspended well costs, all capitalized less than one year and included in wells in progress at December 31, 2018 . These exploratory well costs are pending further engineering evaluation and analysis to determine if economic quantities of oil and gas reserves have been discovered. The Company expects its analysis to be complete in the second half of 2019. As of December 31, 2017 , $15.7 million of suspended well costs, all capitalized less than one year and included in wells in progress as of December 31, 2017 . At September 30, 2018, the Company completed its evaluation and moved $17.9 million of these suspended well costs to proved oil and gas properties based on the determination of proved reserves. As of December 31, 2016 , the Company had no suspended well costs recorded. Geological and geophysical costs are expensed as incurred. Costs of seismic studies that are utilized in development drilling within an area of proved reserves are capitalized as development costs. Amounts of seismic costs capitalized are based on only those blocks of data used in determining development well locations. To the extent that a seismic project covers areas of both developmental and exploratory drilling, those seismic costs are proportionately allocated between development costs and exploration expense. The Company expensed $0.4 million and $1.4 million of costs associated with exploratory geological and geophysical costs for the years ended December 31, 2018 and 2017, respectively. There were no exploratory geological and geophysical costs incurred for the year ended December 31, 2016. The Company capitalizes interest, if debt is outstanding, during drilling operations in its exploration and development activities. For the years ended December 31, 2018 , 2017 and 2016 , the Company capitalized interest of approximately $8.2 million , $11.1 million and $5.2 million , respectively. Net carrying values of retired, sold or abandoned properties that constitute less than a complete unit of depreciable property are charged or credited, net of proceeds, to accumulated depreciation, depletion and amortization unless doing so significantly affects the unit-of-production amortization rate, in which case a gain or loss is recognized in income. Gains or losses from the disposal of complete units of depreciable property are recognized to earnings. For sales of entire working interests in unproved properties, gain or loss is recognized to the extent of the difference between the proceeds received and the net carrying value of the property. Proceeds from sales of partial interests in unproved properties are accounted for as a recovery of costs unless the proceeds exceed the entire cost of the property. |
Impairment of Oil and Gas Properties | Impairment of Oil and Gas Properties Proved oil and gas properties are reviewed for impairment annually or when events and circumstances indicate a possible decline in the recoverability of the carrying amount of such property. For all of its fields, the Company estimates the expected future cash flows of its oil and gas properties and compares these undiscounted cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will write down the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, estimates of reserves, future commodity prices, future production estimates, estimated future capital expenditures, estimated future operating costs, and discount rates commensurate with the risk associated with realizing the projected cash flows. Impairment expense for proved oil and gas properties is reported in impairment of long lived assets and goodwill in the consolidated statements of operations, which increases accumulated depletion, depreciation and amortization. For the years ended December 31, 2018 and 2016 , the Company recognized $16.2 million and $22.5 million , respectively, in impairment expense on proved oil and gas properties in the Company's northern field. As of September 30, 2018, the future undiscounted cash flows did not exceed its carrying amount associated with its proved oil and gas properties in its northern field. As of June 30, 2016, it was determined that the proved oil and gas properties had no remaining fair value, therefore, the full net book value of these proved oil and gas properties were impaired. For the year ended December 31, 2017 , the Company recognized no impairment expense on proved oil and gas properties. Unproved oil and gas properties consist of costs to acquire unevaluated leases as well as costs to acquire unproved reserves. The Company evaluates significant unproved oil and gas properties for impairment based on remaining lease term, drilling results, reservoir performance, seismic interpretation or future plans to develop acreage. When successful wells are drilled on undeveloped leaseholds, unproved property costs are reclassified to proved properties and depleted on a unit‑of‑production basis. Impairment expense and lease extension payments for unproved properties is reported in exploration expenses in the consolidated statements of operations. As a result of the abandonment and impairment of unproved properties, the Company recognized $25.7 million , $15.8 million and $22.3 million in impairment expense for the years ended December 31, 2018 , 2017 and 2016 , respectively. |
Other Property and Equipment | Other Property and Equipment Other property and equipment consists of (i) other property and equipment including, office furniture and fixtures, leasehold improvements and computer hardware and software, (iii) compressors used in Extraction’s oil and gas operations, (iii) land, compressor stations, central tank batteries, and disposal well facilities and (iv) rights of ways, pipeline, and engineering costs. Impairment expense for other property and equipment is reported in impairment of long lived assets and goodwill in the consolidated statements of operations. The Company recognized $0.4 million , $0.9 million and $0.5 million in impairment expense related to midstream facilities for the years ended December 31, 2018 , 2017 and 2016 , respectively, which increased accumulated depreciation recognized in other property and equipment, net of accumulated depreciation. The Company recognized the impairment expense for the year ended December 31, 2018 and 2017 primarily as the result of right-of-way options that were no longer in the Company's plans for developing midstream infrastructure. The Company recognized the impairment expense for the years ended December 31, 2016, as the result of contraction in the local oil and gas industry’s near term growth profile, therefore decreasing the need and support for a specifically proposed gas processing facility. Gain or loss on the sale of other property and equipment is reported in (gain) loss on sale of property and equipment in the consolidated statement of operations. The Company recognized $0.5 million of loss on the sale of other property and equipment related to the disposal of an oil pipeline that was not yet placed into service in the first quarter of 2017. Other property and equipment is recorded at cost and depreciated using the straight‑line method. The estimated useful lives of those assets depreciated under the straight-line basis are as follows: Rental equipment 1-10 years Office leasehold improvements 3-10 years Other 3-5 years Other property and equipment is comprised of the following (in thousands): As of December 31, 2018 2017 Rental equipment $ 4,043 $ 3,805 Land 27,595 22,991 Right-of-ways and pipeline 8,008 7,447 Office leasehold improvements 7,231 4,405 Other 6,946 5,578 Less: accumulated depreciation and impairment (13,974 ) (11,797 ) $ 39,849 $ 32,429 |
Equity Method Investments | Equity Method Investments Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the equity method. The Company recorded $15.5 million and $8.3 million of such investments included in other non-current assets on the consolidated balance sheets as of December 31, 2018 and 2017 , respectively. The Company recognized $2.9 million and $0.4 million of income from such investments, including the accretion of any basis difference between the carrying amount of the investment and the amount of underlying equity in net assets, included in other income on the consolidated statements of operations and equity in earnings of unconsolidated subsidiary, in which we have a minority ownership interest on the consolidated statements of cash flows for the year ended December 31, 2018 and 2017 , respectively. The Company held no such investments during the years ended December 31, 2016. |
Deferred Lease Incentives | Deferred Lease Incentives All incentives received from landlords for office leasehold improvements are recorded as deferred lease incentives and amortized over the term of the respective lease on a straight‑line basis as a reduction of rental expense. |
Debt Discount and Issuance Costs | Debt Discount Costs The $430.0 million in Second Lien Notes issued in May of 2014 were issued at a 1.5% original issue discount (“OID”) and the debt discount of $6.5 million was recorded as a reduction of the Second Lien Notes. The debt discount costs related to Second Lien Notes were amortized to interest expense using the effective interest method over the term of the debt. Debt Issuance Costs Debt issuance costs include origination, legal, engineering, and other fees incurred to issue the debt in connection with the Company’s credit facility, 2021 Senior Notes, 2024 Senior Notes and 2026 Senior Notes (collectively, the "Senior Notes"). Debt issuance costs related to the credit facility are included in other non-current assets on the consolidated balance sheets and amortized to interest expense on the consolidated statement of operations on a straight‑line basis over the respective borrowing term. Debt issuance costs related to the Senior Notes are amortized to interest expense using the effective interest method over the term of the debt. |
Commodity Derivative Instruments | Commodity Derivative Instruments The Company has entered into commodity derivative instruments to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. The commodity derivative instruments are measured at fair value and are included in the accompanying balance sheets as commodity derivative assets and commodity derivative liabilities. The Company has not designated any of the derivative contracts as fair value or cash flow hedges. Therefore, the Company does not apply hedge accounting to the commodity derivative instruments. Net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments. Net gains and losses on commodity derivative instruments are recorded in the commodity derivative gain (loss) line on the consolidated statements of operations. The Company’s cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty. These settlements under the commodity derivative contracts are reflected as operating activities in the Company’s consolidated statements of cash flows. Any premiums paid on derivative contracts are capitalized as part of the derivative assets or derivative liabilities, as appropriate, at the time the premiums are paid. Premium payments are reflected in cash flows from operating activities in the Company's consolidated statements of cash flows. Over time, as the derivative contracts settle, the differences between the cash received and the premiums paid or fair value of contracts acquired are recognized in net gains or losses on commodity or interest rate derivate contracts, and the cash received is reflected in cash flows from operating activities in the Company's consolidated statements of cash flows. The Company’s valuation estimate takes into consideration the counterparties’ credit worthiness, the Company’s credit worthiness, and the time value of money. The consideration of these factors result in an estimated exit‑price for each derivative asset or liability under a market place participant’s view. Management believes that this approach provides a reasonable, non‑biased, verifiable, and consistent methodology for valuing commodity derivative instruments. Please refer to Note 6 — Commodity Derivative Instruments for additional discussion on commodity derivative instruments. |
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets The Company applies the provisions of ASC 350, Intangibles-Goodwill and Other . Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in business combinations. The Company tests goodwill for impairment annually on September 30, or whenever other circumstances or events indicate that the carrying amount of goodwill may not be recoverable. The goodwill test is performed at the reporting unit level, which represents the Company’s oil and gas operations in its core DJ Basin field. If indicators of impairment are determined to exist, an impairment charge is recognized if the carrying value of goodwill exceeds its implied fair value. Any sharp prolonged decreases in the prices of oil and natural gas as well as continued declines in the quoted market price of the Company’s common shares could change the estimates of the fair value of the reporting unit and could result in an impairment charge. The Company performed a quantitative assessment as of September 30, 2018, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company identified triggering events as of December 31, 2018, due to the decrease in commodity pricing and the quoted market price of the Company's common shares compared to September 30, 2018. As such, the Company performed a quantitative assessment as of December 31, 2018 , utilizing an income approach based on estimates of the expected discounted future cash flows of the reporting unit's oil and gas properties, which concluded the fair value of the reporting unit was not greater than its carrying amount. As a result, the Company recorded goodwill impairment of $54.2 million , the entirety of the balance, for the year ended December 31, 2018 . The Company performed a quantitative assessment as of September 30, 2017, which concluded the fair value of the reporting unit was greater than its carrying amount. The Company performed a qualitative assessment as of December 31, 2017 and 2016, which concluded the fair value of the reporting unit was more-likely-than-not greater than its carrying amount. Costs relating to the acquisition of internal-use software licenses are capitalized when incurred and amortized over the estimated useful life of the license, which is typically one to three years. The Company recorded $3.0 million , $2.3 million and $0.3 million of internal-use software for the years ended December 31, 2018 , 2017 and 2016 , respectively, on the consolidated balance sheets within the goodwill and other intangible assets line item. Accumulated amortization for the years ended December 31, 2018 , and 2017 was $3.1 million and $1.1 million , respectively. The Company recognized $2.1 million , $1.0 million and $0.1 million amortization expense for the years ended December 31, 2018 , 2017 and 2016 , respectively. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, commodity derivative instruments (discussed above) and long‑term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are representative of their fair values due to their short‑term maturities. The carrying amount of the Company’s credit facility approximates fair value as it bears interest at variable rates over the term of the loan. The Company’s Senior Notes are recorded at cost and the fair value is disclosed in Note 8 — Fair Value Measurements . Considerable judgment is required to develop estimates of fair value. The estimates provided are not necessarily indicative of the amounts the Company would realize upon the sale or refinancing of such instruments. |
Asset Retirement Obligation | Asset Retirement Obligation The Company recognizes estimated liabilities for future costs associated with the abandonment of its oil and gas properties. A liability for the fair value of an asset retirement obligation and corresponding increase to the carrying value of the related long‑lived asset are recorded at the time the Company makes the decision to complete the well or a well is acquired. For additional discussion on asset retirement obligations please refer to Note 7 — Asset Retirement Obligations. |
Environmental Liabilities | Environmental Liabilities The Company is subject to federal, state and local environmental laws and regulations. These laws regulate the release, disposal or discharge of materials into the environment or otherwise relating to environmental protection and may require the Company to remove or mitigate the environmental effects of the discharge, disposal or release of petroleum substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed. Liabilities for expenditures of a non‑capital nature are recorded when environmental assessments and/or remediation is probable, and the costs can be reasonably estimated. Such liabilities are generally undiscounted values unless the timing of cash payments for the liability or component is fixed or determinable. Management has determined that no significant environmental liabilities existed as of December 31, 2018 . |
Revenue Recognition | Revenue Recognition Revenues from the sale of oil, natural gas and NGL are recognized when the product is delivered at a fixed or determinable price, title has transferred, and collectability is reasonably assured and evidenced by a contract. The Company recognizes revenues from the sale of oil, natural gas and NGL using the sales method of accounting, whereby revenue is recorded based on the Company’s share of volume sold, regardless of whether the Company has taken its proportional share of volume produced. A receivable or liability is recognized only to the extent that the Company has an imbalance on a specific property greater than the expected remaining proved reserves. As of December 31, 2018 , the Company has an oil imbalance of 22 MBbl, which the Company intends to settle with the counterparty in crude oil barrels. There were no material imbalances at December 31, 2017 or 2016 . |
Unit and Stock-Based Payments | Unit and Stock‑Based Payments The Company and its predecessor, Holdings, has granted restricted unit awards ("RUAs"), restricted stock units ("RSUs"), stock option awards and performance stock awards ("PSAs") to certain directors, officers and employees of the Company, which therefore required the Company to recognize the expense in its financial statements. All unit and stock‑based payments to directors, officers and employees are measured at fair value on the grant date and expensed over the relevant service period. The fair value of stock option awards is determined by using the Black-Scholes option pricing model. The fair value of the PSAs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. All unit and stock‑based payment expense is recognized using the straight‑line method and is included within general and administrative expenses in the consolidated statements of operations and unit and stock-based compensation in the consolidated statements of cash flows. Forfeitures are recorded as they occur. Please refer to Note 11 — Unit and Stock‑Based Compensation for additional discussion on unit and stock‑based payments. |
Income Taxes | Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are calculated by applying existing tax laws and the rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The tax returns and the amount of taxable income or loss are subject to examination by deferral and state taxing authorities. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets, including net operating losses. In making this determination, the Company considers all the available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends, and its outlook for future years. The Company believes it is more likely than not that certain net operating losses can be carried forward and utilized. 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 on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company does not currently have uncertain tax positions. On December 22, 2017, United States legislation referred to as the Tax Cuts and Jobs Act (the "TCJA") was signed into law. Many of the provisions of the TCJA are effective for taxable years beginning after December 31, 2017. The TCJA includes changes to the Internal Revenue Code of 1986 (as amended, the "Code"). The most significant change included in the TCJA is a reduction in the corporate federal income tax rate from 35% to 21%. As a result of the enactment date of December 22, 2017, the Company was required to remeasure the deferred tax assets and liabilities at the rate in which they are expected to reverse. This re-measurement of deferred tax assets and liabilities required the Company to analyze and record a one-time adjustment to reduce the overall deferred tax liability in the consolidated balance sheets and affect a corresponding income tax benefit in the consolidated statements of operations for the year ended December 31, 2017. The Company believes the accounting is complete regarding the revaluation of the deferred tax balances. This resulted in the recording of an income tax benefit of $23.4 million , as well as a corresponding reduction in the deferred tax liability as of December 31, 2017. During the third quarter of 2018, we completed the accounting for the income tax effect of the TCJA's limit on compensation under Internal Revenue Code Sec. 162(m) and stock-based compensation for covered employees. This resulted in a $0.4 million reduction in deferred tax assets that had been recorded as a provisional amount as of December 31, 2017 . There are no remaining provisional amounts associated with the TCJA as of December 31, 2018 . Extraction Oil & Gas Holdings, LLC, the Company’s accounting predecessor, was a limited liability company that was not subject to U.S. federal income tax. |
Earnings Per Share | Earnings Per Share Basic earnings per share (“EPS”) includes no dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of shares outstanding during the period. Diluted EPS reflects the potential dilution of securities that could share in the earnings available to common shareholders of the Company. The Company uses the “if-converted” method to determine the potential dilutive effects of its Series A Preferred Stock, and the treasury stock method to determine the potential dilutive effect of outstanding restricted stock units and stock option awards. The Company’s EPS calculation for the year ended December 31, 2016 includes only the net income (loss) for the period subsequent to IPO and Corporate Reorganization which occurred on October 12, 2016 and has omitted EPS prior to this date. In addition, the basic weighted average shares outstanding calculation for the year ended December 31, 2016 is based on the actual days in which the shares were outstanding for the period from October 12, 2016, to December 31, 2016. |
Segment Reporting | Segment Reporting Beginning in the fourth quarter of 2018, the Company had two operating segments, (i) the exploration, development and production of oil, natural gas and NGL (the "exploration and production segment") and (ii) the construction and support of midstream assets to gather and process crude oil and gas production (the "gathering and facilities segment"). Prior to the fourth quarter of 2018, the Company had a single operating segment. The gathering systems and facilities operating segment is currently under development. Capital expenditures associated with gathering systems and facilities are being incurred to develop midstream infrastructure to support the Company's development of its oil and gas leasehold along with third-party activity. The activity of the exploration and production segment and gathering systems and facilities operating segment are being monitored by our chief operating decision maker ("CODM"). The Company expects the first phase of the gathering systems and facilities to be operational during the second half of 2019. Revenues associated with the exploration and production segment are derived from the sale of our oil and natural gas production, as well as the sale of NGL that are extracted from our natural gas during processing. Revenues and operating expenses associated with the gathering systems and facilities operations will be primarily derived from intersegment transactions for services provided to the Company's exploration, development and production operations by Elevation Midstream, LLC., an unrestricted subsidiary to the Company. All intersegment transactions are and will be eliminated upon consolidation, including revenues and operating expenses during the construction of and from gathering services provided by Elevation Midstream to the Company. The CODM considers Adjusted EBITDAX as the measure of segment performance under ASC 280, Segment Reporting . Accounting policies for each segment are the same as the accounting policies as described herein. For more information about Segments, see Note 15 — Segment Information. All of the Company’s operations are conducted in one geographic area of the United States. All revenues are derived from customers located in the United States. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements The accounting standard‑setting organizations frequently issue new or revised accounting rules. The Company regularly reviews new pronouncements to determine their impact, if any, on its consolidated financial statements and related disclosures. In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2019, including interim reporting periods within that reporting period. The Company is currently evaluating this new standard to determine the potential impact to its financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, which improves the disclosure requirements on fair value measurements. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2019, including interim reporting periods within that reporting period. The Company is currently evaluating this new standard to determine the potential impact to its financial statements and related disclosures. In May 2017, the FASB issued ASU No. 2017-09, which provides clarification and reduces both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718 Compensation - Stock Compensation, to a change to the terms or conditions of a share-based payment award. For public entities, the new guidance was effective for fiscal years beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company adopted this ASU on January 1, 2018 and the adoption of this ASU did not have a material impact on the consolidated financial statements and related disclosures. In February 2017, the FASB issued ASU No. 2017-05, which provided clarification regarding the guidance on accounting for the derecognition of nonfinancial assets. For public entities, the new guidance was effective for fiscal years beginning after December 15, 2017, including interim reporting periods within that fiscal year. The Company adopted this ASU on January 1, 2018 and the adoption of this ASU did not have a material impact on the consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. For public entities, the new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of adopting this ASU, however it is not expected to have a significant effect on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-01, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. For public entities, the new guidance was effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted this ASU on January 1, 2018 and the adoption of this ASU did not have a material impact on the consolidated financial statements and related disclosures; however, this standard may result in more transactions being accounted for as asset acquisitions rather than business combinations. In November 2016, the FASB issued ASU No. 2016-18, which intends to clarify how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. This amendment was effective retrospectively for reporting periods beginning after December 15, 2017. The Company adopted this ASU on January 1, 2018 and the retrospective adoption increased the Company's beginning cash balances within the statement of cash flows for the prior period presented in the table below. The adoption had no other material impact on the cash flow statement and had no impact on the Company's results of operations or financial position. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets to the consolidated statement of cash flows: As of December 31, December 31, December 31, December 31, 2018 2017 2016 2015 Cash and cash equivalents $ 234,986 $ 6,768 $ 588,736 $ 97,106 Restricted cash included in cash held in escrow — — 42,200 — $ 234,986 $ 6,768 $ 630,936 $ 97,106 In August 2016, the FASB issued ASU No. 2016-15, which addresses eight specific cash flow issues, including presentation of debt prepayments or debt extinguishment costs, with the objective of reducing the existing diversity in practice. For public entities, the new guidance was effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted this ASU on January 1, 2018, which requires current period make-whole premiums to be presented in financing activities in the statement of cash flows and prior period debt prepayment costs to be reclassified from operating activities to financing activities in the statement of cash flows; however, there was no impact to the total change in cash and cash equivalents from period to period. In February 2016, the FASB issued ASU No. 2016-02, which requires lessee recognition on the balance sheet of a right of use asset and a lease liability, initially measured at the present value of the lease payments. It further requires recognition in the income statement of a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis. Finally, it requires classification of all cash payments within operating activities in the statements of cash flows. It is effective for fiscal years commencing after December 15, 2018 and early adoption is permitted. The FASB subsequently issued ASU No. 2017-13, ASU No. 2018-01, ASU No. 2018-10 and ASU No. 2018-11, which provided additional implementation guidance. The Company is currently evaluating the impact this ASU will have on the consolidated financial statements and related disclosures and expects certain lease agreements with terms over one year to be classified as right-of-use assets and right-of-use liabilities, which will gross up the consolidated balance sheet as of January 1, 2019. The Company will adopt the accounting standard using a modified retrospective transition approach, which applies the provisions of the new guidance at the effective date without adjusting the comparative periods presented. The Company has elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, requires no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for existing leases upon adoption. The Company has also elected the optional practical expedient permitted under the transition guidance within the new standard related to land easements that allows it to carry forward its current accounting treatment for land easements on existing agreements upon adoption. The Company made an accounting policy election to keep leases with an initial term of twelve months or less off of the consolidated balance sheet. The Company is finalizing its evaluation of the impacts that the adoption of this accounting guidance will have on the consolidated financial statements and on our future consolidated balance sheet upon adoption. As a part of the implementation work, the Company is validating the inputs and outputs of the software tool used to calculate the initial and ongoing accounting balances for right-of-use assets and liabilities and finalizing the completeness of the lease population. In May 2014, the FASB issued ASU No. 2014-09, which establishes a comprehensive new revenue recognition model, referred to as ASC 606 - Revenue from Contracts with Customers, designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The ASU allows for the use of either the full or modified retrospective transition method. In August 2015, the FASB issued ASU No. 2015-14, which deferred ASU No. 2014-09 for one year, and was effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The FASB subsequently issued ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, ASU No. 2016-12, ASU No. 2016-20, ASU No. 2017-13, ASU No. 2017-14 and ASU No. 2019-20, which provided additional implementation guidance. Refer to —Adoption of ASC 606 for more information. Adoption of ASC 606 On January 1, 2018, the Company adopted ASC 606. The Company adopted ASC 606 using the modified retrospective method to apply the new standard to all new contracts entered into on or after January 1, 2018 and all existing contracts for which all (or substantially all) of the revenue has not been recognized under legacy revenue guidance. ASC 606 supersedes previous revenue recognition requirements in ASC 605 and includes a five-step revenue recognition model to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The impact of adoption in the year ended December 31, 2018 results are as follows (in thousands): Under ASC 606 Under ASC 605 Change Revenues: Oil sales $ 840,687 $ 840,687 $ — Natural gas sales 105,629 121,180 (15,551 ) NGL sales 114,427 134,558 (20,131 ) Total Revenues 1,060,743 1,096,425 (35,682 ) Operating Expenses: Transportation and gathering $ 39,411 $ 75,093 $ (35,682 ) Revenues less transportation and gathering $ 1,021,332 $ 1,021,332 $ — Changes to sales of natural gas and NGL, and transportation and gathering expenses are due to the conclusion that certain midstream processing entities are the Company's customers in natural gas processing and marketing agreements in accordance with the five-step process in ASC 606. This is a change from previous conclusions reached for these agreements utilizing the principal versus agent indicators under ASC 605 where the Company determined it was the principal, the midstream processor was the agent and the third-party end user was its customer. As a result, the Company modified its presentation of revenues and operating expenses for these agreements. Revenues related to these agreements are now presented on a net basis for proceeds expected to be received from the midstream processing entity. Revenues from the sale of oil, natural gas and NGL, where the Company is a non-operating interest partner, are considered in the scope of ASC 808 - Collaborative Arrangements . Therefore, ASC 606 did not change the presentation of these revenues. Transportation and gathering expense related to other agreements incurred prior to the transfer of control to the customer at the tailgate of the natural gas processing facilities will continue to be presented as transportation and gathering expense. Revenues from Contracts with Customers Sales of oil, natural gas and NGL are recognized at the point control of the commodity is transferred to the customer and collectability is reasonably assured. The majority of the Company's contracts' pricing provisions are tied to a commodity market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of the oil or natural gas, and prevailing supply and demand conditions. As a result, the price of the oil, natural gas and NGL fluctuates to remain competitive with the other available oil, natural gas and NGL supplies. Oil Sales Under the Company's crude purchase and marketing contracts, the Company generally sells oil production at the wellhead and collects an agreed-upon index price, net of pricing differentials. In this scenario, the Company recognizes revenue when control transfers to the purchaser at the wellhead at the net price received. The Company utilizes the sales method to account for producer imbalances, which continues to be applicable under ASC 606. As of December 31, 2018 , the Company has an oil imbalance of 22 MBbl, which the Company intends to settle with the counterparty in crude oil barrels. Natural Gas and NGL Sales Under the Company's natural gas processing contracts, the Company delivers natural gas to a midstream processing entity at the wellhead or the inlet of the midstream processing entity's system. The midstream processing entity gathers and processes the natural gas and remits proceeds to the Company for the resulting sales of NGL and residue gas. In these scenarios, we evaluate whether we are the principal or the agent in the transaction, and the point at which control of the hydrocarbons transfer to the customer. For those contracts where the Company has concluded the midstream processing entity is the Company's agent and the third-party end user is its customer (generally the Company's fixed-fee gathering and processing agreements), the Company recognizes revenue on a gross basis, with transportation and gathering expense presented as an operating expense in the consolidated statements of operations. Alternatively, for those contracts where the Company has concluded the midstream processing entity is its customer and controls the hydrocarbons (generally the Company's percentage of proceeds gathering and processing agreements), the Company recognizes natural gas and NGL revenues based on the net amount of the proceeds received from the midstream processing company. In certain natural gas processing agreements, the Company may elect to take its residue gas and/or NGL in-kind at the tailgate of the midstream entity's processing plant and subsequently market the product. Through the marketing process, the Company delivers product to the third-party purchaser at a contractually agreed-upon delivery point and receives a specified index price from the purchaser. In this scenario, the Company recognizes revenue when the control transfers to the purchaser at the delivery point based on the index price received from the purchaser. The gathering and processing expense attributable to the gas processing contracts, as well as any transportation expense incurred to deliver the product to the purchaser, are presented as transportation and gathering expense in the consolidated statements of operations. Performance Obligations A significant number of the Company's product sales are short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price of a contract that has an original expected duration of one year or less. For the Company's product sales that have a contract term greater than one year, the Company has utilized the practical expedient in ASC 606-10-50-14(a), which states the Company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required. The Company records revenue on its oil, natural gas and NGL sales at the time production is delivered to the purchaser. However, settlement statements for certain oil, natural gas and NGL sales may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the customer and the net commodity price that will be received for the sale of these commodity products. The Company records the differences between the revenue estimated and the actual amounts received for product sales in the month that payment is received from the customer. The Company has internal controls over its revenue estimation process and related accruals, and any identified differences between its revenue estimates and actual revenue received historically have not been significant. For the period from January 1, 2018 to December 31, 2018 , revenue recognized in the reporting period related to performance obligations satisfied in prior reporting periods was not material. Contract Balances Under the Company's various sales contracts, the Company invoices customers once its performance obligations have been satisfied, at which point payment is unconditional. Accordingly, the Company's product sales contracts do not give rise to contract assets or liabilities under ASC 606. The following table presents the Company's revenues disaggregated by revenue source. Transportation and gathering costs in the following table are not all of the transportation and gathering expenses that the Company incurs, only the expenses that are netted against revenues pursuant to ASC 606. Prior period amounts have not been adjusted under the modified retrospective method. For the Year Ended December 31, 2018 2017 2016 Revenues: Oil sales $ 840,687 $ 419,904 $ 194,059 Natural gas sales 121,180 92,322 48,652 NGL sales 134,558 92,070 35,378 Transportation and gathering included in revenues (35,682 ) — — Total Revenues $ 1,060,743 $ 604,296 $ 278,089 There are no other accounting standards applicable to the Company that have been issued but not yet adopted by the Company as of December 31, 2018 , and through the date of this filing that would have a material impact on the Company’s consolidated financial statements and related disclosures. |
