Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Earthstone Energy, Inc., a Delaware corporation (“Earthstone” and together with its consolidated subsidiaries, the “Company”), is a growth-oriented independent oil and natural gas development and production company. In addition, the Company is active in corporate mergers and the acquisition of oil and natural gas properties that have production and future development opportunities. The Company's operations are all in the upstream segment of the oil and natural gas industry and all its properties are onshore in the United States. Earthstone is the sole managing member of Earthstone Energy Holdings, LLC, a Delaware limited liability company (together with its wholly-owned consolidated subsidiaries, “EEH”), with a controlling interest in EEH. Earthstone, together with its wholly-owned subsidiary, Lynden Energy Corp., a corporation organized under the laws of British Columbia (“Lynden Corp”), and Lynden Corp’s wholly-owned consolidated subsidiary, Lynden USA Inc., a Utah corporation (“Lynden US”) and also a member of EEH, consolidates the financial results of EEH and records a noncontrolling interest in the Condensed Consolidated Financial Statements representing the economic interests of EEH's members other than Earthstone and Lynden US. The accompanying unaudited Condensed Consolidated Financial Statements and notes thereto have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim financial statements. Pursuant to such rules and regulations, certain disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted. The accompanying unaudited Condensed Consolidated Financial Statements and notes should be read in conjunction with the financial statements and notes included in Earthstone’s 2019 Annual Report on Form 10-K. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for the fair presentation of the Company's financial position, results of operations and cash flows for the periods presented. The Company’s Condensed Consolidated Balance Sheet at December 31, 2019 is derived from the audited Consolidated Financial Statements at that date. Certain prior period amounts have been reclassified to conform to current period presentation within the Condensed Consolidated Financial Statements. Prior period ad valorem taxes which were previously included in Lease operating expenses within the Operating Costs and Expenses section of the Condensed Consolidated Statements of Operations have been reclassified from Lease operating expenses and combined with the previously presented Severance taxes line-item and the combined total presented as Production and ad valorem taxes, also within Operating Costs and Expenses, in order to conform to current period presentation. Additionally, prior period legal expenses related to a previously completed transaction and previously included in General and administrative expense within Operating Costs and Expenses have been reclassified to Transaction costs, also within Operating Costs and Expenses, to conform to current period presentation. These reclassifications had no effect on Income from operations or any other subtotal in the Condensed Consolidated Statements of Operations. Recently Issued Accounting Standards Intangibles – Goodwill and Other – In January 2017, the Financial Accounting Standards Board ("FASB") issued updated guidance simplifying the test for goodwill impairment. The update eliminates the requirement to determine the implied value of goodwill in measuring an impairment loss. Upon adoption, the measurement of a goodwill impairment will represent the excess of the reporting unit’s carrying value over its fair value and will be limited to the carrying value of goodwill. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the update effective January 1, 2020. See further discussion of goodwill in Note 15. Goodwill . Fair Value Measurements – In August 2018, the FASB issued an Accounting Standards Update ("ASU") which modifies the disclosure requirements on fair value measurements in Topic 820. The ASU is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted. The Company adopted the update effective January 1, 2020 and the impact was not material to the Condensed Consolidated Financial Statements. Credit Losses - In June 2016, the FASB issued an update that requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income, including loans, debt securities, trade receivables, net investments in leases and available-for-sale debt securities. The amended standard broadens the information that an entity must consider in developing its estimate of expected credit losses, requiring an entity to estimate credit losses over the life of an exposure based on historical information, current information and reasonable and supportable forecasts. The guidance is effective for interim and annual periods beginning after December 15, 2019. The Company adopted the update effective January 1, 2020 and the impact was not material to the Condensed Consolidated Financial Statements. Income Taxes - In December 2019, the FASB issued an update that simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. The Company is in the process of evaluating the impact of this update, if any, on its Condensed Consolidated Financial Statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB Accounting Standards Codification ("ASC") Topic 820, defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. ASC 820 provides a framework for measuring fair value, establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and requires consideration of the counterparty’s creditworthiness when valuing certain assets. The three-level fair value hierarchy for disclosure of fair value measurements defined by ASC 820 is as follows: Level 1 – Unadjusted, quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 – Inputs, other than quoted prices within Level 1, that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 – Prices or valuations that require unobservable inputs that are both significant to the fair value measurement and unobservable. Valuation under Level 3 generally involves a significant degree of judgment from management. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instrument’s complexity. The Company reflects transfers between the three levels at the beginning of the reporting period in which the availability of observable inputs no longer justifies classification in the original level. There were no transfers between fair value hierarchy levels for the three months ended March 31, 2020 . Fair Value on a Recurring Basis Derivative financial instruments are carried at fair value and measured on a recurring basis. The derivative financial instruments consist of swaps for crude oil and natural gas. The Company’s swaps are valued based on a discounted future cash flow model. The primary input for the model is published forward commodity price curves. The swaps are also designated as Level 2 within the valuation hierarchy. The fair values of commodity derivative instruments in an asset position include a measure of counterparty nonperformance risk, and the fair values of commodity derivative instruments in a liability position include a measure of the Company’s nonperformance risk. These measurements were not material to the Condensed Consolidated Financial Statements. The following table summarizes the fair value of the Company’s financial assets and liabilities, by level within the fair-value hierarchy (in thousands) : March 31, 2020 Level 1 Level 2 Level 3 Total Financial assets Derivative asset - current $ — $ 72,017 $ — $ 72,017 Derivative asset - noncurrent — 20,769 — 20,769 Total financial assets $ — $ 92,786 $ — $ 92,786 Financial liabilities Derivative liability - current $ — $ — $ — $ — Derivative liability - noncurrent — — — — Total financial liabilities $ — $ — $ — $ — December 31, 2019 Financial assets Derivative asset - current $ — $ 8,860 $ — $ 8,860 Derivative asset - noncurrent 770 770 Total financial assets $ — $ 9,630 $ — $ 9,630 Financial liabilities Derivative liability - current $ — $ 6,889 $ — $ 6,889 Derivative liability - noncurrent — — — — Total financial liabilities $ — $ 6,889 $ — $ 6,889 Other financial instruments include cash, accounts receivable and payable, and revenue royalties. The carrying amount of these instruments approximates fair value because of their short-term nature. The Company’s long-term debt obligation bears interest at floating market rates, therefore carrying amounts and fair value are approximately equal. Fair Value on a Nonrecurring Basis The Company applies the provisions of the fair value measurement standard on a non-recurring basis to its non-financial assets and liabilities, including oil and gas properties, goodwill, business combinations, asset retirement obligations and performance units. These assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments if events or changes in certain circumstances indicate that adjustments may be necessary. Due to significant declines in commodity prices and global demand for oil and natural gas products resulting from the COVID-19 pandemic, the Company assessed the fair values of its oil and natural gas properties and goodwill resulting in non-cash impairment charges during the three months ended March 31, 2020. See further discussion at Note 4. Asset Impairments .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company’s hedging activities consist of derivative instruments entered into in order to hedge against changes in oil and natural gas prices through the use of fixed price swap agreements. Swaps exchange floating price risk in the future for a fixed price at the time of the hedge. Consistent with its hedging policy, the Company has entered into a series of derivative instruments to hedge a significant portion of its expected oil and natural gas production through December 31, 2021. Typically, these derivative instruments require payments to (receipts from) counterparties based on specific indices as required by the derivative agreements. Although not risk free, the Company believes these instruments reduce its exposure to oil and natural gas price fluctuations and, thereby, allow the Company to achieve a more predictable cash flow. The Company’s derivative instruments are cash flow hedge transactions in which it is hedging the variability of cash flow related to a forecasted transaction. The Company does not enter into derivative instruments for trading or other speculative purposes. These transactions are recorded in the Condensed Consolidated Financial Statements in accordance with FASB ASC Topic 815. The Company has accounted for these transactions using the mark-to-market accounting method. Generally, the Company incurs accounting losses on derivatives during periods where prices are rising and gains during periods where prices are falling which may cause significant fluctuations in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Operations. The Company nets its derivative instrument fair value amounts executed with each counterparty pursuant to an International Swap Dealers Association Master Agreement (“ISDA”), which provides for net settlement over the term of the contract. The ISDA is a standard contract that governs all derivative contracts entered into between the Company and the respective counterparty. The ISDA allows for offsetting of amounts payable or receivable between the Company and the counterparty, at the election of both parties, for transactions that occur on the same date and in the same currency.

Oil and Gas Exploration and Production Industries Disclosures [Abstract]
Oil and Natural Gas Properties	Oil and Natural Gas Properties The Company follows the successful efforts method of accounting for its oil and natural gas properties. Under this method, costs to acquire oil and natural gas properties, drill and equip exploratory wells that find proved reserves, and drill and equip development wells are capitalized. Exploration costs, including unsuccessful exploratory wells and geological and geophysical costs, are charged to operations as incurred. Upon sale or retirement of oil and natural gas properties, the costs and related accumulated depreciation, depletion and amortization are eliminated from the accounts and the resulting gain or loss is recognized. Costs incurred to maintain wells and related equipment, lease and well operating costs, and other exploration costs are charged to expense as incurred. Gains and losses arising from the sale of properties are included in Income from operations in the Condensed Consolidated Statements of Operations. The Company’s lease acquisition costs and development costs of proved oil and natural gas properties are amortized using the units-of-production method, at the field level, based on total proved reserves and proved developed reserves, respectively. For the three months ended March 31, 2020 and 2019 , depletion expense for oil and gas producing property and related equipment was $24.5 million and $13.8 million , respectively. Proved Properties Proved oil and natural gas properties are reviewed for impairment on a nonrecurring basis. The impairment charge reduces the carrying values to their estimated fair values. These fair value measurements are classified as Level 3 measurements and include many unobservable inputs. Fair value is calculated as the estimated discounted future net cash flows attributable to the assets. The Company’s primary assumptions in preparing the estimated discounted future net cash flows to be recovered from oil and gas properties are based on (i) proved reserves, (ii) forward commodity prices and assumptions as to costs and expenses, and (iii) the estimated discount rate that would be used by potential purchasers to determine the fair value of the assets. Unproved Properties Unproved properties consist of costs incurred to acquire undeveloped leases. Unproved oil and gas leases are generally for a primary term of three to five years . In most cases, the term of the unproved leases can be extended by paying a lease renewal fee, meeting contractual drilling obligations, or by the presence of producing wells on the leases. Unproved costs related to successful drilling on unproved leases are reclassified to proved properties. The Company reviews its unproved properties periodically for impairment. In determining whether an unproved property is impaired, the Company considers numerous factors including, but not limited to, current exploration and development plans, favorable or unfavorable exploration activity on the property being evaluated and/or adjacent properties, the Company’s geologists' evaluation of the property, and the remaining months in the lease term for the property. Impairments to Oil and Natural Gas Properties During the three months ended March 31, 2020 , as a result of the recent decline in crude oil price futures, the Company recorded non-cash impairment charges of $25.3 million and $11.3 million to its proved and unproved oil and natural gas properties, respectively, located in the Eagle Ford Trend. As a result of certain acreage expirations, the Company recorded non-cash impairment charges of $6.2 million during the three months ended March 31, 2020 . The Company did no t record any impairments to its oil and natural gas properties for the three months ended March 31, 2019 . Capitalized costs, impairment, and depreciation, depletion and amortization relating to the Company’s oil and natural gas properties as of March 31, 2020 and December 31, 2019 , are summarized below ( in thousands ): March 31, December 31, 2020 2019 Oil and gas properties, successful efforts method: Proved properties $ 1,091,861 $ 1,046,208 Accumulated impairment to proved properties (100,652 ) (75,400 ) Proved properties, net of accumulated impairments 991,209 970,808 Unproved properties 301,666 305,961 Accumulated impairment to Unproved properties (63,189 ) (45,690 ) Unproved properties, net of accumulated impairments 238,477 260,271 Land 5,382 5,382 Total oil and gas properties, net of accumulated impairments 1,235,068 1,236,461 Accumulated depreciation, depletion and amortization (219,823 ) (195,567 ) Net oil and gas properties $ 1,015,245 $ 1,040,894

Earnings Per Share [Abstract]
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share Net income (loss) per common share—basic is calculated by dividing Net income (loss) by the weighted average number of shares of common stock outstanding during the period. Net income (loss) per common share—diluted assumes the conversion of all potentially dilutive securities and is calculated by dividing Net income (loss) by the sum of the weighted average number of shares of common stock, as defined above, outstanding plus potentially dilutive securities. Net income (loss) per common share—diluted considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares, as defined above, would have an anti-dilutive effect. A reconciliation of Net income (loss) per common share is as follows: Three Months Ended (In thousands, except per share amounts) 2020 2019 Net income (loss) attributable to Earthstone Energy, Inc. $ 16,708 $ (17,204 ) Net income (loss) per common share attributable to Earthstone Energy, Inc.: Basic $ 0.57 $ (0.60 ) Diluted $ 0.57 $ (0.60 ) Weighted average common shares outstanding Basic 29,497,428 28,719,542 Add potentially dilutive securities: Unvested restricted stock units (1) — — Unvested performance units (1) — — Diluted weighted average common shares outstanding 29,497,428 28,719,542 (1) For the three months ended March 31, 2020, the Company had no dilutive effect related to unvested restricted stock units or performance units as, under the treasury stock method, the proceeds from the average unrecognized expense for both during the period were in excess of the weighted average outstanding fair value for the unvested shares for the same period. Class B Common Stock has been excluded, as its conversion would eliminate noncontrolling interest and net income (loss) attributable to noncontrolling interest of $20.0 million for the three months ended March 31, 2020 would be added back to Net income (loss) attributable to Earthstone Energy, Inc. for the period then ended, having no dilutive effect on Net income (loss) per common share attributable to Earthstone Energy, Inc.

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Restricted Stock Units The 2014 Plan, allows, among other things, for the grant of restricted stock units (“RSUs”). As of March 31, 2020 , the maximum number of shares of Class A Common Stock that may be issued under the 2014 Plan was 6.4 million shares. Each RSU represents the contingent right to receive one share of Class A Common Stock. The holders of outstanding RSUs do not receive dividends or have voting rights prior to vesting and settlement. The Company determines the fair value of granted RSUs based on the market price of the Class A Common Stock on the date of the grant. Compensation expense for granted RSUs is recognized on a straight-line basis over the vesting and is net of forfeitures, as incurred. Stock-based compensation is included in General and administrative expense in the Condensed Consolidated Statements of Operations and is recorded with a corresponding increase in Additional paid-in capital within the Condensed Consolidated Balance Sheets. The table below summarizes RSU award activity for the three months ended March 31, 2020 : Shares Weighted-Average Grant Date Fair Value Unvested RSUs at December 31, 2019 1,107,796 $ 6.60 Granted 568,900 $ 5.15 Vested (307,529 ) $ 6.79 Unvested RSUs at March 31, 2020 1,369,167 $ 5.95 As of March 31, 2020 , there was $8.0 million of unrecognized compensation expense related to the RSU awards which will be recognized over a weighted average period of 1.04 years . For the three months ended March 31, 2020 , Stock-based compensation related to RSUs was $1.7 million . For the three months ended March 31, 2019 , Stock-based compensation related to RSUs was $1.6 million . Performance Units The table below summarizes performance unit (“PSU”) activity for the three months ended March 31, 2020 : Shares Weighted-Average Grant Date Fair Value Unvested PSUs at December 31, 2019 835,625 $ 10.51 Granted 1,043,800 $ 5.36 Unvested PSUs at March 31, 2020 1,879,425 $ 7.65 On January 30, 2020, subject to approval of an amendment to the 2014 Plan to increase the number of available shares thereunder available for awards at the 2020 annual stockholder meeting, the Board of Directors of Earthstone (the “Board”) granted 1,043,800 PSUs to certain officers pursuant to the 2014 Plan. The PSUs are payable in shares of Class A Common Stock based upon the achievement by the Company over a period commencing on February 1, 2020 and ending on January 31, 2023 (the “Performance Period”) of performance criteria established by the Board. The PSUs are eligible to be earned based on the annualized Total Shareholder Return (“TSR”) of the Class A Common Stock during a three-year period beginning on February 1, 2020. Between 0x to 2.0x of the Performance Units are eligible to be earned based on our achieving an annualized TSR based on the following pre-established goals: Company’s Annualized TSR TSR Multiplier 23.9% or greater 2.0 14.5% 1.0 8.4% 0.5 Less than 8.4% 0.0 In the event that greater than 1.0x of the PSUs are earned, such additional PSUs may be paid in cash rather than the issuance of shares of Class A Common Stock. Based on the COVID-19 pandemic and the recent commodity price crash, we believe that the target annualized TSR of 14.5% included in the 2020 PSU awards will be difficult to achieve. The Company accounts for these awards as market-based awards which are valued utilizing the Monte Carlo Simulation pricing model, which calculates multiple potential outcomes for an award and establishes grant date fair value based on the most likely outcome. For the PSUs granted on January 30, 2020, assuming a risk-free rate of 1.4% and volatility of 62.0% , the Company calculated the weighted average grant date fair value per PSU to be $5.36 . As of March 31, 2020 , there was $9.7 million of unrecognized compensation expense related to the PSU awards which will be amortized over a weighted average period of 1.18 years . For the three months ended March 31, 2020 , Stock-based compensation related to the PSUs was approximately $1.0 million . For the three months ended March 31, 2019 , Stock-based compensation related to the PSUs was approximately $0.6 million .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal From time to time, Earthstone and its subsidiaries may be involved in various legal proceedings and claims in the ordinary course of business. Olenik v. Lodzinski et al.: On June 2, 2017, Nicholas Olenik filed a purported shareholder class and derivative action in the Delaware Court of Chancery against Earthstone’s Chief Executive Officer, along with other members of the Board, EnCap Investments L.P. (“EnCap”), Bold, Bold Holdings and Oak Valley Resources, LLC. The complaint alleges that Earthstone’s directors breached their fiduciary duties in connection with the contribution agreement dated as of November 7, 2016 and as amended on March 21, 2017 (the “Bold Contribution Agreement”), by and among Earthstone, EEH, Lynden US, Lynden USA Operating, LLC, Bold Holdings and Bold. The Plaintiff asserts that the directors negotiated the business combination pursuant to the Bold Contribution Agreement (the “Bold Transaction") to benefit EnCap and its affiliates, failed to obtain adequate consideration for the Earthstone shareholders who were not affiliated with EnCap or Earthstone management, did not follow an adequate process in negotiating and approving the Bold Transaction and made materially misleading or incomplete proxy disclosures in connection with the Bold Transaction. The suit seeks unspecified damages and purports to assert claims derivatively on behalf of Earthstone and as a class action on behalf of all persons who held common stock up to March 13, 2017, excluding defendants and their affiliates. On July 20, 2018, the Delaware Court of Chancery granted the defendants’ motion to dismiss and entered an order dismissing the action in its entirety with prejudice. The Plaintiff filed an appeal with the Delaware Supreme Court. On February 6, 2019, the Delaware Supreme Court heard oral arguments from the Plaintiff’s and Defendants’ counsel. On April 5, 2019, the Delaware Supreme Court affirmed the Delaware Court of Chancery’s dismissal of the proxy disclosure claims but reversed the Delaware Court of Chancery’s dismissal of the other claims, holding that the allegations with respect to those claims were sufficient for pleading purposes. Earthstone and each of the other defendants believe the claims are entirely without merit and intend to mount a vigorous defense. The ultimate outcome of this suit is uncertain, and while Earthstone is confident in its position, any potential monetary recovery or loss to Earthstone cannot be estimated at this time. Environmental and Regulatory As of March 31, 2020 , there were no known environmental or other regulatory matters related to the Company’s operations that are reasonably expected to result in a material liability to the Company.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s corporate structure requires the filing of two separate consolidated U.S. Federal income tax returns and one Canadian income tax return which include Lynden US, Earthstone, and Lynden Corp. As such, taxable income of Earthstone cannot be offset by tax attributes, including net operating losses, of Lynden US, nor can taxable income of Lynden US be offset by tax attributes of Earthstone. Earthstone and Lynden US record a tax provision, respectively, for their share of the book income or loss of EEH, net of the non-controlling interest. As EEH is treated as a partnership for U.S. Federal income tax purposes, it is not subject to income tax at the federal level and only recognizes the Texas Margin Tax. During the three months ended March 31, 2020 , the Company recorded income tax expense of approximately $1.1 million which included (1) income tax expense for Lynden US of $0.7 million as a result of its share of the distributable income from EEH, (2) deferred income tax expense for Earthstone of $2.9 million as a result of its share of the distributable income from EEH, which was used to reduce the valuation allowance recorded against its deferred tax asset which was previously recorded as future realization of the net deferred tax asset cannot be assured and (3) deferred income tax expense of $0.4 million related to the Texas Margin Tax. Lynden Corp incurred no material income or loss, or related income tax expense or benefit, for the three months ended March 31, 2020 . During the three months ended March 31, 2019 , the Company recorded income tax benefit of approximately $0.5 million which included (1) income tax benefit for Lynden US of $0.8 million as a result of its share of the distributable income from EEH, (2) income tax benefit for Earthstone of $2.9 million as a result of its share of the distributable income from EEH, which was used to reduce the valuation recorded against its deferred tax asset as future realization of the net deferred tax asset cannot be assured and (3) deferred income tax expense of $0.3 million related to the Texas Margin Tax. Lynden Corp incurred no material income or loss, or related income tax expense or benefit, for the three months ended March 31, 2019.

Goodwill

Goodwill	3 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the excess of the purchase price of assets acquired over the fair value of those assets. The fair value of Goodwill is classified as a Level 3 measurement according to the fair value hierarchy defined by ASC 820. Goodwill is tested for impairment annually, or more frequently if events or changes in circumstances dictate that the carrying value of goodwill may not be recoverable. Such test includes an assessment of qualitative and quantitative factors. If the results of such tests are such that the fair value of the reporting unit is less than the carrying value, goodwill is then reduced by an amount that is equal to the amount by which the carrying value exceeds the fair value. A future cash flow analysis of the Midland properties, to which the Goodwill was associated, was performed based on commodity price futures as of March 31, 2020. The resulting fair value was lower than the net book value of the associated properties. Additionally, the Company’s enterprise value, calculated as the combined market capitalization of the Company’s equity and the fair value of the Company’s long-term debt, was lower than the fair value of the assets, without allocating between the Company's two major properties, Midland properties and Eagle Ford properties. Accordingly, the entire balance of Goodwill was impaired. As such, the Company recorded a $17.6 million non-cash impairment charge during the three months ended March 31, 2020 . The Company did no t have any non-cash impairment charges to its goodwill for the three months ended March 31, 2019. Accumulated impairments to Goodwill as of March 31, 2020 and December 31, 2019 were $36.7 million and $19.1 million , respectively.

Accounting Policies [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Intangibles – Goodwill and Other – In January 2017, the Financial Accounting Standards Board ("FASB") issued updated guidance simplifying the test for goodwill impairment. The update eliminates the requirement to determine the implied value of goodwill in measuring an impairment loss. Upon adoption, the measurement of a goodwill impairment will represent the excess of the reporting unit’s carrying value over its fair value and will be limited to the carrying value of goodwill. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the update effective January 1, 2020. See further discussion of goodwill in Note 15. Goodwill . Fair Value Measurements – In August 2018, the FASB issued an Accounting Standards Update ("ASU") which modifies the disclosure requirements on fair value measurements in Topic 820. The ASU is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted. The Company adopted the update effective January 1, 2020 and the impact was not material to the Condensed Consolidated Financial Statements. Credit Losses - In June 2016, the FASB issued an update that requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income, including loans, debt securities, trade receivables, net investments in leases and available-for-sale debt securities. The amended standard broadens the information that an entity must consider in developing its estimate of expected credit losses, requiring an entity to estimate credit losses over the life of an exposure based on historical information, current information and reasonable and supportable forecasts. The guidance is effective for interim and annual periods beginning after December 15, 2019. The Company adopted the update effective January 1, 2020 and the impact was not material to the Condensed Consolidated Financial Statements. Income Taxes - In December 2019, the FASB issued an update that simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. The Company is in the process of evaluating the impact of this update, if any, on its Condensed Consolidated Financial Statements.
