Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Note 1 - Summary of Significant Accounting Policies Description of Operations SM Energy Company, together with its consolidated subsidiaries (“SM Energy” or the “Company”), is an independent energy company engaged in the acquisition, exploration, development, and production of crude oil and condensate, natural gas, and natural gas liquids (also respectively referred to as “oil,” “gas,” and “NGLs” throughout this report) in onshore North America. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information, the instructions to Quarterly Report on Form 10-Q, and Regulation S-X. These financial statements do not include all information and notes required by GAAP for annual financial statements. However, except as disclosed herein, there has been no material change in the information disclosed in the notes to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “ 2018 Form 10-K”). In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation of interim financial information, have been included. Operating results for the periods presented are not necessarily indicative of expected results for the full year. In connection with the preparation of the Company’s unaudited condensed consolidated financial statements, the Company evaluated events subsequent to the balance sheet date of March 31, 2019 , and through the filing of this report. Certain prior period amounts have been reclassified to conform to the current presentation on the accompanying unaudited condensed consolidated financial statements. Significant Accounting Policies The significant accounting policies followed by the Company are set forth in Note 1 - Summary of Significant Accounting Policies in the 2018 Form 10-K and are supplemented by the notes to the unaudited condensed consolidated financial statements included in this report. These unaudited condensed consolidated financial statements should be read in conjunction with the 2018 Form 10-K. Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), followed by other related ASUs that provided targeted improvements and additional practical expedient options (collectively “ASU 2016-02” or “Topic 842”). The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective method. The Company elected as part of its adoption to also use the optional transition methodology whereby previously reported periods continue to be reported in accordance with historical accounting guidance for leases that were in effect for those prior periods. Policy elections and practical expedients the Company has implemented in connection with the adoption of ASU 2016-02, include (a) excluding from the balance sheet leases with terms that are less than one year, (b) for agreements that contain both lease and non-lease components, combining these components together and accounting for them as a single lease, (c) the package of practical expedients, which among other requirements, allows the Company to avoid reassessing contracts that commenced prior to adoption that were properly evaluated under legacy GAAP, and (d) excluding land easements that existed or expired before adoption of ASU 2016-02. The scope of ASU 2016-02 does not apply to leases used in the exploration or use of minerals, oil, natural gas, or other similar non-regenerative resources. Upon adoption on January 1, 2019, the Company recognized approximately $50.0 million in right-of-use (“ROU”) assets and related lease liabilities for its operating leases. There was no cumulative effect to retained earnings upon the adoption of this guidance. Please refer to Note 12 - Leases for additional discussion. Other than as disclosed in the 2018 Form 10-K, there are no ASUs that would have a material effect on the Company’s consolidated financial statements and related disclosures that have been issued but not yet adopted by the Company as of March 31, 2019 , and through the filing of this report. |

Revenue from Contract with Customer [Abstract] | |
Revenue from Contracts with Customers | Note 2 - Revenue from Contracts with Customers The Company recognizes its share of revenue from the sale of produced oil, gas, and NGLs in its Permian and South Texas & Gulf Coast regions. As a result of divestiture activity in the first half of 2018, there has been no production revenue from the Rocky Mountain region after the second quarter of 2018. Oil, gas, and NGL production revenue presented within the accompanying unaudited condensed consolidated statements of operations (“accompanying statements of operations”) is reflective of the revenue generated from contracts with customers. The table below presents oil, gas, and NGL production revenue by product type for each of the Company’s operating regions for the three months ended March 31, 2019 , and 2018 : Permian South Texas & Gulf Coast Rocky Mountain Total Three Months Ended March 31, Three Months Ended March 31, Three Months Ended March 31, Three Months Ended March 31, 2019 2018 2019 2018 2019 2018 2019 2018 (in thousands) Oil production revenue $ 225,247 $ 205,794 $ 13,814 $ 19,583 $ — $ 35,683 $ 239,061 $ 261,060 Gas production revenue 15,592 24,876 49,521 52,733 — 1,500 65,113 79,109 NGL production revenue 21 124 36,281 41,770 — 823 36,302 42,717 Total $ 240,860 $ 230,794 $ 99,616 $ 114,086 $ — $ 38,006 $ 340,476 $ 382,886 Relative percentage 71 % 60 % 29 % 30 % — % 10 % 100 % 100 % ____________________________________________ Note: Amounts may not calculate due to rounding. The Company recognizes oil, gas, and NGL production revenue at the point in time when custody and title (“control”) of the product transfers to the customer, which differs depending on the contractual terms of each of the Company’s arrangements. Transfer of control drives the presentation of transportation, gathering, processing, and other post-production expenses (“fees and other deductions”) within the accompanying statements of operations. Fees and other deductions incurred prior to control transfer are recorded within the oil, gas, and NGL production expense line item on the accompanying statements of operations, while fees and other deductions incurred subsequent to control transfer are embedded in the price and effectively recorded as a reduction of oil, gas, and NGL production revenue. Please refer to Note 2 - Revenue from Contracts with Customers in the 2018 Form 10-K for more information regarding the types of contracts under which oil, gas, and NGL production revenue is generated. Significant judgments made in applying the guidance in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers relate to the point in time when control transfers to customers in gas processing arrangements with midstream processors. The Company does not believe that significant judgments are required with respect to the determination of the transaction price, including amounts that represent variable consideration, as volume and price carry a low level of estimation uncertainty given the precision of volumetric measurements and the use of index pricing with predictable differentials. Accordingly, the Company does not consider estimates of variable consideration to be constrained. The Company’s contractual performance obligations arise upon the production of hydrocarbons from wells in which the Company has an ownership interest. The performance obligations are considered satisfied upon control transferring to a customer at the wellhead, inlet, or tailgate of the midstream processor’s processing facility, or other contractually specified delivery point. The time period between production and satisfaction of performance obligations is generally less than one day; thus, there are no material unsatisfied or partially unsatisfied performance obligations at the end of the reporting period. Revenue is recorded in the month when contractual performance obligations are satisfied. However, settlement statements from the purchasers of hydrocarbons and the related cash consideration are received 30 to 90 days after production has occurred. As a result, the Company must estimate the amount of production delivered to the customer and the consideration that will ultimately be received for sale of the product. Estimated revenue due to the Company is recorded within the accounts receivable line item on the accompanying unaudited condensed consolidated balance sheets (“accompanying balance sheets”) until payment is received. The accounts receivable balances from contracts with customers within the accompanying balance sheets as of March 31, 2019 , and December 31, 2018 , were $109.4 million and $107.2 million , respectively. To estimate accounts receivable from contracts with customers, the Company uses knowledge of its properties, historical performance, contractual arrangements, index pricing, quality and transportation differentials, and other factors as the basis for these estimates. Differences between estimates and actual amounts received for product sales are recorded in the month that payment is received from the purchaser. Revenue recognized during the three months ended March 31, 2019 , that related to performance obligations satisfied in prior reporting periods, was immaterial. |

Divestitures, Assets Held for Sale, and Acquisitions [Abstract] | |
Divestitures, Assets Held for Sale, and Acquisitions | Note 3 - Divestitures, Assets Held for Sale, and Acquisitions Divestitures On March 26, 2018 , the Company divested approximately 112,000 net acres of its Powder River Basin assets (the “PRB Divestiture”) for total cash received at closing, net of costs (referred to throughout this report as “net divestiture proceeds”), of $490.8 million , and recorded an estimated net gain of $409.2 million for the three months ended March 31, 2018 . After final purchase price adjustments, the Company received net divestiture proceeds of $492.2 million , and recorded a final net gain of $410.6 million related to these divested assets for the year ended December 31, 2018 . During the first quarter of 2018, the company entered into definitive agreements for the sale of its Divide County assets (the “Divide County Divestiture”) and its Halff East assets in the Midland Basin (the “Halff East Divestiture”). Certain of these assets were written down by $24.1 million during the first quarter of 2018 to reflect fair value less estimated costs to sell upon classification as held for sale. These divestitures were completed during the second quarter of 2018. Acquisitions During the first quarter of 2019 , the Company completed several non-monetary acreage trades of undeveloped properties located in Howard, Martin, and Midland Counties, Texas, resulting in the exchange of approximately 2,000 net acres, with $65.8 million of carrying value attributed to the properties surrendered by the Company. These trades were recorded at carryover basis with no gain or loss recognized. No such trades occurred during the first quarter of 2018 . |

Income Tax Disclosure [Abstract] | |
Income Taxes | Note 4 - Income Taxes The income tax (expense) benefit recorded for the three months ended March 31, 2019 , and 2018 , differs from the amounts that would be provided by applying the statutory United States federal income tax rate to income or loss before income taxes primarily due to the effect of state income taxes, excess tax benefits and deficiencies from share-based payment awards, limitations on the compensation of certain covered individuals, changes in valuation allowances, and accumulated impacts of other smaller permanent differences. The quarterly rate can also be affected by the proportional impacts of forecasted net income or loss as of each period end presented. The provision for income taxes for the three months ended March 31, 2019 , and 2018 , consisted of the following: For the Three Months Ended March 31, 2019 2018 (in thousands) Current portion of income tax (expense) benefit: Federal $ — $ — State (965 ) (625 ) Deferred portion of income tax (expense) benefit 47,003 (98,366 ) Income tax (expense) benefit $ 46,038 $ (98,991 ) Effective tax rate 20.6 % 23.8 % The change in the Company’s effective tax rate for the periods presented in the table above generally reflects differences in its estimated highest marginal state tax rate due to changes in the composition of income or loss from Company activities, including divestitures, among multiple state tax jurisdictions. Future periods are not expected to reflect these differences as the Company’s current activities are occurring predominately in Texas. For years before 2015, the Company is generally no longer subject to United States federal or state income tax examinations by tax authorities. |

Debt Disclosure [Abstract] | |
Long-Term Debt | Note 5 - Long-Term Debt Credit Agreement As of March 31, 2019 , the Company’s Sixth Amended and Restated Credit Agreement (the “Credit Agreement”) provided for a senior secured revolving credit facility with a maximum loan amount of $2.5 billion , an initial borrowing base of $1.5 billion , and initial aggregate lender commitments totaling $1.0 billion , which were unchanged from December 31, 2018 . On April 18, 2019 , the Company entered into the First Amendment to the Credit Agreement (the “First Amendment”) with its lenders. Pursuant to the First Amendment, and as part of the regular, semi-annual borrowing base redetermination process, the borrowing base and aggregate lender commitments were increased to $1.6 billion and $1.2 billion , respectively. The borrowing base increase was primarily driven by the increased value of the Company’s estimated proved reserves at December 31, 2018 . The next scheduled borrowing base redetermination date is October 1, 2019 . The Credit Agreement is scheduled to mature on September 28, 2023 . The maturity date could, however, occur earlier on August 16, 2022, if the Company has not completed certain repurchase, redemption, or refinancing activities associated with its 6.125% Senior Notes due 2022 (“2022 Senior Notes”), as outlined in the Credit Agreement. Please refer to Note 5 - Long-Term Debt in the 2018 Form 10-K for additional detail on the terms of the Company’s Credit Agreement. The Company must comply with certain financial and non-financial covenants under the terms of the Credit Agreement and was in compliance with all such covenants as of March 31, 2019 , and through the filing of this report. Interest and commitment fees are accrued based on a borrowing base utilization grid set forth in the Credit Agreement as presented in Note 5 - Long-Term Debt in the Company’s 2018 Form 10-K. At the Company’s election, borrowings under the Credit Agreement may be in the form of Eurodollar, Alternate Base Rate (“ABR”), or Swingline loans.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Compensation Plans | Note 7 - Compensation Plans Performance Share Units The Company grants performance share units (“PSUs”) to eligible employees as part of its long-term equity incentive compensation program. The number of shares of the Company’s common stock issued to settle PSUs ranges from zero to two times the number of PSUs awarded and is determined based on certain performance criteria over a three -year performance period. PSUs generally vest on the third anniversary of the date of the grant or upon other triggering events as set forth in the Company’s Equity Incentive Compensation Plan (“Equity Plan”). PSUs are subject to a combination of market, performance, and service vesting criteria. Awards with a market criteria component are based on annualized Total Shareholder Return (“TSR”) for the performance period and the relative performance of the Company’s TSR compared with the annualized TSR of the Company’s peer group for the performance period. Compensation expense for market-based PSUs is recognized on a straight-line basis within general and administrative expense and exploration expense over the vesting periods of the respective awards. Awards with a performance criteria component are based on relative debt adjusted per share cash flow growth (“DACFG”) compared with DACFG, as calculated by the Company, of its peer group that is evaluated over the three -year performance period. Compensation expense for performance-based PSUs will be evaluated on a quarterly basis and may be adjusted as the number of units expected to vest increases or decreases. Total compensation expense recorded for PSUs was $2.8 million and $2.4 million for the three months ended March 31, 2019 , and 2018 , respectively. As of March 31, 2019 , there was $15.9 million of total unrecognized compensation expense related to non-vested PSU awards, which is being amortized through 2021. There have been no material changes to the outstanding and non-vested PSUs during the three months ended March 31, 2019 . Employee Restricted Stock Units The Company grants restricted stock units (“RSUs”) to eligible persons as part of its long-term equity incentive compensation program. Each RSU represents a right to receive one share of the Company’s common stock upon settlement of the award at the end of the specified vesting period. Compensation expense for RSUs is recognized within general and administrative expense and exploration expense over the vesting periods of the respective awards. RSUs granted to employees generally vest one-third on each anniversary date of the grant over a three -year vesting period or upon other triggering events as set forth in the Company’s Equity Plan. Total compensation expense recorded for employee RSUs was $2.7 million for each of the three months ended March 31, 2019 , and 2018 . As of March 31, 2019 , there was $16.4 million of total unrecognized compensation expense related to non-vested RSU awards, which is being amortized through 2021. There have been no material changes to the outstanding and non-vested RSUs during the three months ended March 31, 2019 . |

Earnings Per Share [Abstract] | |
Earnings per Share | Note 9 - Earnings Per Share Basic net income or loss per common share is calculated by dividing net income or loss available to common stockholders by the basic weighted-average number of common shares outstanding for the respective period. Diluted net income or loss per common share is calculated by dividing net income or loss by the diluted weighted-average number of common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for this calculation consist primarily of non-vested RSUs, contingent PSUs, and shares into which the Senior Convertible Notes are convertible, which are measured using the treasury stock method. Shares of the Company’s common stock traded at an average closing price below the $40.50 conversion price for the three months ended March 31, 2019 , and 2018 , and therefore the Senior Convertible Notes had no dilutive impact. Please refer to Note 9 - Earnings Per Share in the 2018 Form 10-K for additional detail on these potentially dilutive securities. When the Company recognizes a loss from continuing operations, all potentially dilutive shares are anti-dilutive and are consequently excluded from the calculation of diluted net loss per common share. The following table details the weighted-average dilutive and anti-dilutive securities for the periods presented: For the Three Months Ended March 31, 2019 2018 (in thousands) Dilutive — 1,183 Anti-dilutive 781 — The following table sets forth the calculations of basic and diluted net income (loss) per common share: For the Three Months Ended March 31, 2019 2018 (in thousands, except per share data) Net income (loss) $ (177,568 ) $ 317,401 Basic weighted-average common shares outstanding 112,252 111,696 Dilutive effect of non-vested RSUs and contingent PSUs — 1,183 Dilutive effect of Senior Convertible Notes — — Diluted weighted-average common shares outstanding 112,252 112,879 Basic net income (loss) per common share $ (1.58 ) $ 2.84 Diluted net income (loss) per common share $ (1.58 ) $ 2.81 |

Derivative Instruments Not Designated as Hedging Instruments [Abstract] | |
Derivative Financial Instruments | Note 10 - Derivative Financial Instruments Summary of Oil, Gas, and NGL Derivative Contracts in Place The Company has entered into various commodity derivative contracts to mitigate a portion of its exposure to potentially adverse market changes in commodity prices and the associated impact on cash flows. As of March 31, 2019 , all derivative counterparties were members of the Company’s Credit Agreement lender group and all contracts were entered into for other-than-trading purposes. The Company’s commodity derivative contracts consist of swap and collar arrangements for oil and gas production, and swap arrangements for NGL production. In a typical commodity swap agreement, if the agreed upon published third-party index price (“index price”) is lower than the swap fixed price, the Company receives the difference between the index price and the agreed upon swap fixed price. If the index price is higher than the swap fixed price, the Company pays the difference. For collar arrangements, the Company receives the difference between an agreed upon index and the floor price if the index price is below the floor price. The Company pays the difference between the agreed upon ceiling price and the index price if the index price is above the ceiling price. No amounts are paid or received if the index price is between the floor and ceiling prices. The Company has also entered into fixed price oil basis swaps in order to mitigate exposure to adverse pricing differentials between certain industry benchmark prices and the actual physical pricing points where the Company’s production volumes are sold. Currently, the Company has basis swap contracts with fixed price differentials between NYMEX WTI and WTI Midland for a portion of its Midland Basin production with sales contracts that settle at WTI Midland prices. The Company also has basis swaps with fixed price differentials between NYMEX WTI and Intercontinental Exchange Brent Crude (“ICE Brent”) for a portion of its Midland Basin oil production with sales contracts that settle at ICE Brent prices. As of March 31, 2019 , the Company had commodity derivative contracts outstanding through the fourth quarter of 2022 as summarized in the tables below.

Derivative Assets and Liabilities Fair Value The Company’s commodity derivatives are measured at fair value and are included in the accompanying balance sheets as derivative assets and liabilities. The Company does not designate its derivative commodity contracts as hedging instruments. The fair value of the commodity derivative contracts was a net liability of $13.8 million at March 31, 2019 , and a net asset of $158.3 million at December 31, 2018 . The following table details the fair value of commodity derivative contracts recorded in the accompanying balance sheets, by category: As of March 31, 2019 As of December 31, 2018 (in thousands) Derivative assets: Current assets $ 67,567 $ 175,130 Noncurrent assets 27,202 58,499 Total derivative assets $ 94,769 $ 233,629 Derivative liabilities: Current liabilities $ 95,269 $ 62,853 Noncurrent liabilities 13,332 12,496 Total derivative liabilities $ 108,601 $ 75,349 Offsetting of Derivative Assets and Liabilities As of March 31, 2019 , and December 31, 2018 , all derivative instruments held by the Company were subject to master netting arrangements with various financial institutions. In general, the terms of the Company’s agreements provide for offsetting of amounts payable or receivable between it and the counterparty, at the election of both parties, for transactions that settle on the same date and in the same currency. The Company’s agreements also provide that in the event of an early termination, the counterparties have the right to offset amounts owed or owing under that and any other agreement with the same counterparty. The Company’s accounting policy is to not offset these positions in its accompanying balance sheets. The following table provides a reconciliation between the gross assets and liabilities reflected on the accompanying balance sheets and the potential effects of master netting arrangements on the fair value of the Company’s commodity derivative contracts: Derivative Assets Derivative Liabilities As of As of March 31, 2019 December 31, 2018 March 31, 2019 December 31, 2018 (in thousands) Gross amounts presented in the accompanying balance sheets $ 94,769 $ 233,629 $ (108,601 ) $ (75,349 ) Amounts not offset in the accompanying balance sheets (52,882 ) (56,041 ) 52,882 56,041 Net amounts $ 41,887 $ 177,588 $ (55,719 ) $ (19,308 ) The following table summarizes the components of the net derivative loss line item presented in the accompanying statements of operations: For the Three Months Ended March 31, 2019 2018 (in thousands) Derivative settlement (gain) loss: Oil contracts $ 1,369 $ 20,748 Gas contracts 4,134 (6,410 ) NGL contracts (534 ) 10,190 Total derivative settlement loss $ 4,969 $ 24,528 Net derivative (gain) loss: Oil contracts $ 185,797 $ 13,966 Gas contracts (6,113 ) 9,990 NGL contracts (2,603 ) (16,427 ) Total net derivative loss $ 177,081 $ 7,529 Credit Related Contingent Features As of March 31, 2019 , and through the filing of this report, all of the Company’s derivative counterparties were members of the Company’s Credit Agreement lender group. Under the Credit Agreement, the Company is required to provide mortgage liens on assets having a value equal to at least 85 percent of the total PV-9 of the Company’s proved oil and gas properties evaluated in the most recent reserve report.

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures | Note 11 - Fair Value Measurements The Company follows fair value measurement accounting guidance for all assets and liabilities measured at fair value. This guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Market or observable inputs are the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The fair value hierarchy for grouping these assets and liabilities is based on the significance level of the following inputs: • Level 1 – quoted prices in active markets for identical assets or liabilities • Level 2 – quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose inputs are observable or whose significant value drivers are observable • Level 3 – significant inputs to the valuation model are unobservable The following table is a listing of the Company’s assets and liabilities that are measured at fair value in the accompanying balance sheets and where they are classified within the fair value hierarchy as of March 31, 2019 : Level 1 Level 2 Level 3 (in thousands) Assets: Derivatives (1) $ — $ 94,769 $ — Liabilities: Derivatives (1) $ — $ 108,601 $ — __________________________________________ (1) This represents a financial asset or liability that is measured at fair value on a recurring basis. The following table is a listing of the Company’s assets and liabilities that are measured at fair value in the accompanying balance sheets and where they were classified within the fair value hierarchy as of December 31, 2018 : Level 1 Level 2 Level 3 (in thousands) Assets: Derivatives (1) $ — $ 233,629 $ — Liabilities: Derivatives (1) $ — $ 75,349 $ — ____________________________________________ (1) This represents a financial asset or liability that is measured at fair value on a recurring basis. Both financial and non-financial assets and liabilities are categorized within the above fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The following is a description of the valuation methodologies used by the Company as well as the general classification of such instruments pursuant to the above fair value hierarchy. Derivatives The Company uses Level 2 inputs to measure the fair value of oil, gas, and NGL commodity derivatives. Fair values are based upon interpolated data. The Company derives internal valuation estimates taking into consideration forward commodity price curves, counterparties’ credit ratings, the Company’s credit rating, and the time value of money. These valuations are then compared to the respective counterparties’ mark-to-market statements. The considered factors result in an estimated exit price that management believes provides a reasonable and consistent methodology for valuing derivative instruments. The commodity derivative instruments utilized by the Company are not considered by management to be complex, structured, or illiquid. The oil, gas, and NGL commodity derivative markets are highly active. Please refer to Note 10 - Derivative Financial Instruments and to Note 11 - Fair Value Measurements in the 2018 Form 10-K for more information regarding the Company’s derivative instruments. Proved and Unproved Oil and Gas Properties and Other Property and Equipment Proved oil and gas properties. Proved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that associated carrying costs may not be recoverable. The Company uses Level 3 inputs and the income valuation technique to measure the fair value of proved properties through the application of discount rates and price forecasts representative of the current operating environment, as selected by the Company’s management. Unproved oil and gas properties. Unproved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that the carrying costs may not be recoverable. To measure the fair value of unproved properties, the Company uses a market approach, which takes into account the following significant assumptions: remaining lease terms, future development plans, risk weighted potential resource recovery, estimated reserve values, and estimated acreage value based on price(s) received for similar, recent acreage transactions by the Company or other market participants. During the three months ended March 31, 2019 , and 2018 , the Company recorded $6.3 million and $5.6 million , respectively, in abandonment and impairment of unproved properties expense related to actual and anticipated lease expirations, as well as actual and anticipated losses on acreage due to title defects, changes in development plans, and other inherent acreage risks. Properties held for sale. Properties classified as held for sale, including any corresponding asset retirement obligation liability, are valued using a market approach, based on an estimated net selling price, as evidenced by the most current bid prices received from third parties, if available. If an estimated selling price is not available, the Company utilizes the various valuation techniques discussed above. Any initial write-down and subsequent changes to the fair value less estimated cost to sell is included within the net gain on divestiture activity line item in the accompanying statements of operations. There were $5.3 million of assets held for sale that were recorded at fair value less estimated costs to sell as of December 31, 2018 . There were no assets held for sale as of March 31, 2019 . For the three months ended March 31, 2018 , write-downs to fair value less estimated costs to sell on assets held for sale totaled $24.1 million . Please refer to Note 3 - Divestitures, Assets Held for Sale, and Acquisitions above and in the 2018 Form 10-K for more information regarding the Company’s oil and gas properties held for sale . Please refer to Note 1 – Summary of Significant Accounting Policies and Note 11 - Fair Value Measurements in the 2018 Form 10-K for more information regarding the Company’s approach in determining fair value of its properties.

Lessee Disclosure [Abstract] | |
Leases | Note 12 - Leases Effective January 1, 2019, the Company adopted Topic 842, which requires lessees to recognize operating and finance leases with terms greater than 12 months on the balance sheet. The Company adopted this standard using the modified retrospective method and elected to use the optional transition methodology whereby reporting periods prior to adoption continue to be presented in accordance with legacy accounting guidance. As of March 31, 2019 , the Company did not have any agreements in place that were classified as finance leases under Topic 842. Arrangements classified as operating leases are included on the accompanying balance sheets within the other noncurrent assets, other current liabilities, and other noncurrent liabilities line items. For any agreement that contains both lease and non-lease components, such as a service arrangement that also includes an identifiable ROU asset, the Company’s policy for all asset classes is to combine lease and non-lease components together and account for the arrangement as a single lease. Aside from the recognition of ROU assets and corresponding lease liabilities on the accompanying balance sheets, Topic 842 will not have a material impact on the timing or classification of costs incurred for those agreements considered to be leases. As outlined in Topic 842, a ROU asset represents a lessee’s right to use an underlying asset for the lease term, while the associated lease liability represents the lessee’s obligations to make lease payments. At the commencement date, which is the date on which a lessor makes an underlying asset available for use by a lessee, a lease ROU asset and corresponding lease liability is recognized based on the present value of the future lease payments. The initial measurement of lease payments may also be adjusted for certain items, including options that are reasonably certain to be exercised, such as options to purchase the asset at the end of the lease term, or options to extend or early terminate the lease. Excluded from the initial measurement of a ROU asset and corresponding lease liability are certain variable lease payments, such as payments made that vary depending on actual usage or performance. The Company evaluates a contractual arrangement at its inception to determine if it is a lease or contains an identifiable lease component as defined by Topic 842. When evaluating a contract to determine appropriate classification and recognition under Topic 842, significant judgment may be necessary to determine, among other criteria, if an embedded leasing arrangement exists, the length of the term, classification as either an operating or financing lease, which options are reasonably likely to be exercised, fair value of the underlying ROU asset or assets, upfront costs, and future lease payments that are included or excluded in the initial measurement of the ROU asset. Certain assumptions and judgments made by the Company when evaluating a contract that meets the definition of a lease under Topic 842 include: • Discount Rate - Unless implicitly defined, the Company will determine the present value of future lease payments using an estimated incremental borrowing rate based on a yield curve analysis that factors in certain assumptions, including the term of the lease and credit rating of the Company at lease inception. • Lease Term - The Company evaluates each contract containing a lease arrangement at inception to determine the length of the lease term when recognizing a ROU asset and corresponding lease liability. When determining the lease term, options available to extend or early terminate the arrangement are evaluated and included when it is reasonably certain an option will be exercised. Because of the Company’s intent to maintain financial and operational flexibility, there are no available options to extend that the Company is reasonably certain it will exercise. Additionally, based on expectations for those agreements with early termination options, there are no leases in which early termination options are reasonably certain to be exercised. Currently, the Company has operating leases for asset classes that include office space, office equipment, drilling rigs, well completion agreements, midstream agreements, vehicles, and equipment rentals used in field operations. For those operating leases included on the accompanying balance sheets, which only includes leases with terms greater than 12 months at commencement, remaining lease terms range from less than one year to approximately seven years. The weighted-average lease term remaining for these leases is 3.2 years. Certain leases also contain optional extension periods that allow for terms to be extended for up to an additional 10 years. An early termination option also exists for certain leases, some of which allow for the Company to terminate a lease within one year. Exercising an early termination option may also result in an early termination penalty depending on the terms of the underlying agreement. Subsequent to initial measurement, costs associated with the Company’s operating leases are either expensed or capitalized depending on how the underlying ROU asset is utilized and in accordance with GAAP requirements. For example, costs associated with drilling rigs and completion crews that are considered ROU assets are typically capitalized as part of the development of the Company’s oil and gas properties. Please refer to Note 1 – Summary of Significant Accounting Policies in the Company’s 2018 Form 10-K for additional information on its accounting policies for oil and gas development and producing activities. When calculating the Company’s ROU asset and liability for a contractual arrangement that qualifies as an operating lease, the Company considers all of the necessary payments made or that are expected to be made upon commencement of the lease. Excluded from the initial measurement are certain variable lease payments, which for the Company’s drilling rigs, completion crews, and midstream agreements, may be a significant component of the total lease costs. For the three months ended March 31, 2019 , total costs related to operating leases, including short-term leases, and variable lease payments made for leases with initial lease terms greater than 12 months, were $175.3 million . This total does not reflect amounts that may be reimbursed by other third-parties in the normal course of business, such as non-operating working interest owners. Components of the Company’s total lease cost, whether capitalized or expensed, for the three months ended March 31, 2019 , were as follows: For the Three Months Ended March 31, 2019 (in thousands) Operating lease cost $ 8,979 Short-term lease cost (1) 134,917 Variable lease cost (2) 31,408 Total lease cost (3) $ 175,304 ____________________________________________ (1) Costs associated with short-term lease agreements relate primarily to operational activities where underlying lease terms are less than one year. This amount is significant as it includes drilling and completion activities and field equipment rentals, most of which are contracted for 12 months or less. It is expected this amount will fluctuate primarily with the number of drilling rigs and completion crews the Company is operating under short-term agreements. (2) Variable lease payments include additional payments made that were not included in the initial measurement of the ROU asset and corresponding liability for lease agreements with terms longer than 12 months. Variable lease payments relate to the actual volumes transported under certain midstream agreements, actual usage associated with drilling rigs and completion crews, and variable utility costs associated with the Company’s leased office space. Fluctuations in variable lease payments are driven by actual volumes delivered and the number of drilling rigs and completion crews operating under long-term agreements. (3) Lease costs are either expensed on the accompanying statements of operations or capitalized on the accompanying balance sheets depending on the nature and use of the underlying ROU asset. Other information related to the Company’s leases for the three months ended March 31, 2019 , was as follows: For the Three Months Ended March 31, 2019 (in thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 9,134 Right-of-use assets obtained in exchange for new operating lease liabilities $ 12,191 Maturities for the Company’s operating lease liabilities included on the accompanying balance sheets as of March 31, 2019 , were as follows: As of March 31, 2019 (in thousands) 2019 (remaining after March 31, 2019) $ 21,217 2020 16,384 2021 11,074 2022 5,123 2023 3,316 Thereafter 3,721 Total Lease payments $ 60,835 Less: Imputed interest (1) (6,339 ) Total $ 54,496 ____________________________________________ (1) The weighted-average discount rate used to determine the operating lease liability as of March 31, 2019 was 6.6 percent . Amounts recorded on the Company’s accompanying balance sheets for operating leases as of March 31, 2019 , were as follows: As of March 31, 2019 (in thousands) Other noncurrent assets $ 51,448 Other current liabilities $ 23,523 Other noncurrent liabilities $ 30,973 As of March 31, 2019 , the Company had an additional long-term operating lease arrangement for a drilling rig that commenced service in April 2019 for approximately $7.8 million with a lease term of 14 months. This agreement is not reflected in the amounts above as the commencement date was subsequent to March 31, 2019. |

Recently Issued Accounting Standards, Policy [Policy Text Block] | Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), followed by other related ASUs that provided targeted improvements and additional practical expedient options (collectively “ASU 2016-02” or “Topic 842”). The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective method. The Company elected as part of its adoption to also use the optional transition methodology whereby previously reported periods continue to be reported in accordance with historical accounting guidance for leases that were in effect for those prior periods. Policy elections and practical expedients the Company has implemented in connection with the adoption of ASU 2016-02, include (a) excluding from the balance sheet leases with terms that are less than one year, (b) for agreements that contain both lease and non-lease components, combining these components together and accounting for them as a single lease, (c) the package of practical expedients, which among other requirements, allows the Company to avoid reassessing contracts that commenced prior to adoption that were properly evaluated under legacy GAAP, and (d) excluding land easements that existed or expired before adoption of ASU 2016-02. The scope of ASU 2016-02 does not apply to leases used in the exploration or use of minerals, oil, natural gas, or other similar non-regenerative resources. Upon adoption on January 1, 2019, the Company recognized approximately $50.0 million in right-of-use (“ROU”) assets and related lease liabilities for its operating leases. There was no cumulative effect to retained earnings upon the adoption of this guidance. Please refer to Note 12 - Leases for additional discussion. Other than as disclosed in the 2018 Form 10-K, there are no ASUs that would have a material effect on the Company’s consolidated financial statements and related disclosures that have been issued but not yet adopted by the Company as of March 31, 2019 , and through the filing of this report. |
Fair Value of Financial Instruments, Policy [Policy Text Block] | Derivatives The Company uses Level 2 inputs to measure the fair value of oil, gas, and NGL commodity derivatives. Fair values are based upon interpolated data. The Company derives internal valuation estimates taking into consideration forward commodity price curves, counterparties’ credit ratings, the Company’s credit rating, and the time value of money. These valuations are then compared to the respective counterparties’ mark-to-market statements. The considered factors result in an estimated exit price that management believes provides a reasonable and consistent methodology for valuing derivative instruments. The commodity derivative instruments utilized by the Company are not considered by management to be complex, structured, or illiquid. The oil, gas, and NGL commodity derivative markets are highly active. Please refer to Note 10 - Derivative Financial Instruments and to Note 11 - Fair Value Measurements in the 2018 Form 10-K for more information regarding the Company’s derivative instruments. |
Property, Plant and Equipment, Impairment, Policy [Policy Text Block] | Proved and Unproved Oil and Gas Properties and Other Property and Equipment Proved oil and gas properties. Proved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that associated carrying costs may not be recoverable. The Company uses Level 3 inputs and the income valuation technique to measure the fair value of proved properties through the application of discount rates and price forecasts representative of the current operating environment, as selected by the Company’s management. Unproved oil and gas properties. Unproved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that the carrying costs may not be recoverable. To measure the fair value of unproved properties, the Company uses a market approach, which takes into account the following significant assumptions: remaining lease terms, future development plans, risk weighted potential resource recovery, estimated reserve values, and estimated acreage value based on price(s) received for similar, recent acreage transactions by the Company or other market participants. During the three months ended March 31, 2019 , and 2018 , the Company recorded $6.3 million and $5.6 million , respectively, in abandonment and impairment of unproved properties expense related to actual and anticipated lease expirations, as well as actual and anticipated losses on acreage due to title defects, changes in development plans, and other inherent acreage risks. Properties held for sale. Properties classified as held for sale, including any corresponding asset retirement obligation liability, are valued using a market approach, based on an estimated net selling price, as evidenced by the most current bid prices received from third parties, if available. If an estimated selling price is not available, the Company utilizes the various valuation techniques discussed above. Any initial write-down and subsequent changes to the fair value less estimated cost to sell is included within the net gain on divestiture activity line item in the accompanying statements of operations. There were $5.3 million of assets held for sale that were recorded at fair value less estimated costs to sell as of December 31, 2018 . There were no assets held for sale as of March 31, 2019 . For the three months ended March 31, 2018 , write-downs to fair value less estimated costs to sell on assets held for sale totaled $24.1 million . Please refer to Note 3 - Divestitures, Assets Held for Sale, and Acquisitions above and in the 2018 Form 10-K for more information regarding the Company’s oil and gas properties held for sale .

Components of total lease cost [Table Text Block] | Components of the Company’s total lease cost, whether capitalized or expensed, for the three months ended March 31, 2019 , were as follows: For the Three Months Ended March 31, 2019 (in thousands) Operating lease cost $ 8,979 Short-term lease cost (1) 134,917 Variable lease cost (2) 31,408 Total lease cost (3) $ 175,304 ____________________________________________ (1) Costs associated with short-term lease agreements relate primarily to operational activities where underlying lease terms are less than one year. This amount is significant as it includes drilling and completion activities and field equipment rentals, most of which are contracted for 12 months or less. It is expected this amount will fluctuate primarily with the number of drilling rigs and completion crews the Company is operating under short-term agreements. (2) Variable lease payments include additional payments made that were not included in the initial measurement of the ROU asset and corresponding liability for lease agreements with terms longer than 12 months. Variable lease payments relate to the actual volumes transported under certain midstream agreements, actual usage associated with drilling rigs and completion crews, and variable utility costs associated with the Company’s leased office space. Fluctuations in variable lease payments are driven by actual volumes delivered and the number of drilling rigs and completion crews operating under long-term agreements. (3) Lease costs are either expensed on the accompanying statements of operations or capitalized on the accompanying balance sheets depending on the nature and use of the underlying ROU asset. Other information related to the Company’s leases for the three months ended March 31, 2019 , was as follows: For the Three Months Ended March 31, 2019 (in thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 9,134 Right-of-use assets obtained in exchange for new operating lease liabilities $ 12,191 |

Total lease cost | [1] | $ 175,304 | |
Operating lease cost | 8,979 | ||
Short-term lease cost | [2] | 134,917 | |

Right-of-use assets obtained in exchange for new operating lease liabilities | $ 50,000 | $ 12,191 | |
[1] | (3) Lease costs are either expensed on the accompanying statements of operations or capitalized on the accompanying balance sheets depending on the nature and use of the underlying ROU asset. | ||
[2] | (1) Costs associated with short-term lease agreements relate primarily to operational activities where underlying lease terms are less than one year. This amount is significant as it includes drilling and completion activities and field equipment rentals, most of which are contracted for 12 months or less. It is expected this amount will fluctuate primarily with the number of drilling rigs and completion crews the Company is operating under short-term agreements. | ||
[3] | (2) Variable lease payments include additional payments made that were not included in the initial measurement of the ROU asset and corresponding liability for lease agreements with terms longer than 12 months. Variable lease payments relate to the actual volumes transported under certain midstream agreements, actual usage associated with drilling rigs and completion crews, and variable utility costs associated with the Company’s leased office space. Fluctuations in variable lease payments are driven by actual volumes delivered and the number of drilling rigs and completion crews operating under long-term agreements. |
