BASIS OF PRESENTATION [Abstract] | |
BASIS OF PRESENTATION | 1. BASIS OF PRESENTATION Description of Operations —Whiting Petroleum Corporation, a Delaware corporation, is an independent oil and gas company engaged in the development, acquisition, exploration and production of crude oil, NGLs and natural gas primarily in the Rocky Mountain s region of the United States. Unless otherwise specified or the context otherwise requires, all references in these notes to “Whiting” or the “Company” are to Whiting Petroleum Corporation and its consolidated subsidiaries, Whiting Oil and Gas Corporation (“Whiting Oil and Gas”), Whiting US Holding Company, Whiting Canadian Holding Company ULC (formerly Kodiak Oil & Gas Corp., “Kodiak”), Whiting Resources Corporation (formerly Kodiak Oil & Gas (USA) Inc.) and Whiting Programs, Inc. Consolidated Financial Statements —The unaudited consolidated financial statements include the accounts of Whiting Petroleum Corporation and its consolidated subsidiaries. Investments in entities which give Whiting significant influence, but not control, over the investee are accounted for using the equity method. Under the equity method, investments are stated at cost plus the Company’s equity in undistributed earnings and losses. All intercompany balances and transactions have been eliminated upon consolidation. These financial statements have been prepared in accordance with GAAP and the SEC rules and regulations for interim financial reporting. In the opinion of management, the accompanying financial statements include all adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly, in all material respects, the Company’s interim results. However, operating results for the periods presented are not necessarily indicative of the results that may be expected for the full year. The consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q should be read in conjunction with Whiting’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2015 . Except as disclosed herein, there have been no material changes to the information disclosed in the notes to consolidated financial statements included in the Company’s 2015 Annual Report on Form 10 ‑K. Earnings Per Share —Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period. Diluted earnings per common share is calculated by dividing adjusted net income available to common shareholders by the weighted average number of diluted common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for the diluted earnings per share calculations consist of (i) convertible debt to be settled in shares only , using the if-converted method and (ii) unvested restricted stock awards, outstanding stock options and contingently issuable shares of convertible debt to be settled in cash, all using the treasury stock method. When a loss from continuing operations exists, all dilutive securities and potentially dilutive securities are anti-dilutive and are therefore excluded from the computation of diluted earnings per share. |

Upon closing of the sale of the North Ward Estes Properties on July 27, 2016, the borrowing base was reduced to $2.6 billion. The Company may increase the maximum aggregate amount of commitments under the credit agreement up to the $2. 6 billion borrowing base if certain conditions are satisfied, including the consent of lenders participating in the increase. As of June 30, 2016 , the Company had $1.5 billion of available borrowing capacity, which was net of $1.0 billion in borrowings and $2 million in letters of credit outstanding. The borrowing base under the credit agreement is determined at the discretion of the lenders, based on the collateral value of the Company’s proved reserves that have been mortgaged to such lenders, and is subject to regular redeterminations on May 1 and November 1 of each year, as well as special redeterminations described in the credit agreement, in each case which may reduce the amount of the borrowing base. Upon a redetermination of the borrowing base, either on a periodic or special redetermination date, if borrowings in excess of the revised borrowing capacity were outstanding, the Company could be forced to immediately repay a portion of its debt outstanding under the credit agreement. The credit agreement permits the Company and certain of its subsidiaries to dispose of their respective ownership interests in certain gas gathering and processing plants located in North Dakota without reducing the borrowing base. A portion of the revolving credit facility in an aggregate amount not to exceed $50 million may be used to issue letters of credit for the account of Whiting Oil and Gas or other designated subsidiaries of the Company. As of June 30, 2016 , $48 million was available for additional letters of credit under the agreement. The credit agreement provides for interest only payments until December 2019, when the credit agreement expires and all outstanding borrowings are due. Interest under the revolving credit facility accrues at the Company’s option at either (i) a base rate for a base rate loan plus the margin in the table below, where the base rate is defined as the greatest of the prime rate, the federal funds rate plus 0.5% per annum, or an adjusted LIBOR rate plus 1.0% per annum, or (ii) an adjusted LIBOR rate for a Eurodollar loan plus the margin in the table below. Additionally, the Company also incurs commitment fees as set forth in the table below on the unused portion of the aggregate commitments of the lenders under the revolving credit facility, which are included as a component of interest expense. At June 30 , 201 6 , the weighted average interest rate on the outstanding principal balance under the credit agreement was 2.7% . Applicable Applicable Margin for Base Margin for Commitment Ratio of Outstanding Borrowings to Borrowing Base Rate Loans Eurodollar Loans Fee Less than 0.25 to 1.0 1.00% 2.00% 0.50% Greater than or equal to 0.25 to 1.0 but less than 0.50 to 1.0 1.25% 2.25% 0.50% Greater than or equal to 0.50 to 1.0 but less than 0.75 to 1.0 1.50% 2.50% 0.50% Greater than or equal to 0.75 to 1.0 but less than 0.90 to 1.0 1.75% 2.75% 0.50% Greater than or equal to 0.90 to 1.0 2.00% 3.00% 0.50% The credit agreement contains restrictive covenants that may limit the Company’s ability to, among other things, incur additional indebtedness, sell assets, make loans to others, make investments, enter into mergers, enter into hedging contracts, incur liens and engage in certain other transactions without the prior consent of its lenders. However, the credit agreement permits the Company and certain of its subsidiaries to issue second lien indebtedness of up to $1.0 billion subject to certain conditions and limitations. Except for limited exceptions, the credit agreement also restricts the Company’s ability to make any dividend payments or distributions on its common stock.

Senior Notes and Senior Subordinated Notes —In September 2010, the Company issued at par $350 million of 6.5% Senior Subordinated Notes due October 2018 (the “2018 Senior Subordinated Notes”). In September 2013, the Company issued at par $1.1 billion of 5% Senior Notes due March 2019 (the “2019 Senior Notes”) and $800 million of 5.75% Senior Notes due March 2021, and issued at 101% of par an additional $400 million of 5.75% Senior Notes due March 2021 (collectively, the “2021 Senior Notes”). The debt premium recorded in connection with the issuance of the 2021 Senior Notes is being amortized to interest expense over the term of the notes using the effective interest method, with an effective interest rate of 5.5% per annum. In March 2015, the Company issued at par $750 million of 6.25% Senior Notes due April 2023 (the “2023 Senior Notes” and together with the 2019 Senior Notes and 2021 Senior Notes, the “Whiting Senior Notes”). Exchange of Senior Notes and Senior Subordinated Notes for Convertible Notes . O n March 23, 2016, the Company completed the exchange of $477 million aggregate principal amount of its senior notes and senior subordinated notes, consisting of (i) $49 million aggregate principal amount of its 2018 Senior Subordinated Notes, (ii) $97 million aggregate principal amount of its 2019 Senior Notes, (iii) $152 million aggregate principal amount of its 2021 Senior Notes , and (iv) $179 million aggregate principal amount of its 2023 Senior Notes , for (i) $49 million aggregate principal amount of new 6.5% Convertible Senior Subordinated Notes due 2018 (the “2018 Convertible Senior Subordinated Notes”), (ii) $97 million aggregate principal amount of new 5% Convertible Senior Notes due 2019 (the “2019 Convertible Senior Note s”), (iii) $152 million aggregate p rincipal amount of new 5.75% Convertible Senior Notes due 2021 (the “202 1 Convertible Senior Notes”), and (iv) $179 million aggregate principal amount of new 6.25% Convertible Senior Notes due 2023 (the “2023 Convertible Senior Notes” and together with the 2018 Convertible Senior Subordinated Notes, the 2019 Convertible Senior Notes and the 2021 Convertible Senior Notes, the “New Convertible Notes”). During the second quarter of 2016, all of the New Convertible Notes converted at the holders’ option into shares of Whiting’s common stock. Refer to “Conversion of New Convertible Notes to Common Stock” below for more information. The redemption provisions, covenants, interest payments and maturity terms applicable to each series of New Convertible Notes were substantially identical to those applicable to the corresponding series of Whiting Senior Notes and 2018 Senior Subordinated Notes. This exchange transaction was accounted for as an extinguishment of debt for each portion of the Whiting Senior Notes and 2018 Senior Subordinated Notes that were exchanged. As a result, Whiting recognized a $91 million gain on extinguishment of debt, which included a $4 million non-cash charge for the acceleration of unamortized debt issuance costs and debt premium on the original notes. Each series of New Convertible Notes was recorded at fair value upon issuance, with the difference between the principal amount of the notes and their fair values, totaling $95 million, recorded as a debt discount. The aggregate debt discount of $185 million recorded upon issuance of the New Convertible Notes also included $90 million related to the fair value of the holders’ conversion options, which were embedded derivatives that met the criteria to be bifurcated from their host contracts and accounted for separately. These embedded derivatives were marked to market with the changes in fair value recorded as derivative (gain) loss, net in the consolidated statements of operations. Refer to the “Derivative Financial Instruments” and “Fair Value Measurements” footnotes for more information. The debt discount was being amortized to interest expense over the respective terms of the notes using the effective interest method. Transaction costs of $8 million attributable to the New Convertible Notes issuance were recorded as a reduction to the carrying value of long-term debt on the consolidated balance sheet and we re being amortized to interest expense over the respective term s of the notes using the effective interest method. The New Convertible Notes were convertible, at the option of the holders, into shares of the Company’s common stock at any time from the date of issuance up until the close of business on the earlier of (i) the fifth business day following the date of a mandatory conversion notice from the Company (see below for a discussion of the mandatory conversion terms), (ii) the business day immediately preceding the date of redemption, if Whiting had elected to redeem all or a portion of the New Convertible Notes prior to maturity, or (iii) the business day immediately preceding the maturity date. In addition, (i) if a holder exercised its right to convert on or prior to September 23, 2016, such holder would have received an early conversion cash payment in an amount equal to 18 months of interest payable on the applicable series of notes, (ii) if a holder exercised its right to convert after September 23, 2016 but on or prior to March 23, 2017, such holder would have received an early conversion cash payment in an amount equal to 12 months of interest payable on the applicable series of notes, or (iii) if a holder exercised its right to convert after March 23, 2017 but on or prior to September 23, 2017, such holder would have received an early conversion cash payment in an amount equal to six months of interest payable on the applicable series of notes. Upon exercise of this option, the holder was also entitled to cash payment of all accrued and unpaid interest through the conversion date. The initial conversion rate for the 2018 Convertible Senior Subordinated Notes, the 2021 Convertible Senior Notes and the 2023 Convertible Senior Notes was 86.9565 common shares per $1,000 principal amount of the notes (representing an initial conversion price of $11.50 per share), and the initial conversion rate for the 2019 Convertible Senior Notes was 90.9091 common shares per $1,000 principal amount of the notes (representing an initial conversion price of $11.00 per share). Each initial conversion rate was subject to customary adjustments if certain share transactions were to be initiated by Whiting. The Company had the right to mandatorily convert the New Convertible Notes, in whole or in part, if the volume weighted average price (as defined in the applicable indentures governing the New Convertible Notes) of the Company’s common stock exceeded 89.13% of the applicable conversion price of the 2018 Convertible Senior Subordinated Notes, the 2021 Convertible Senior Notes and the 2023 Convertible Senior Notes and 93.18% of the applicable conversion price of the 2019 Convertible Senior Notes (each representing an initial mandatory conversion trigger price of $10.25 per share) for at least 20 trading days during a 30 consecutive trading day period. No early conversion or accrued and unpaid interest payments would have been made upon a mandatory conversion. Conversion of New Convertible Notes to Common Stock . During the second quarter of 2016, holders of the New Convertible Notes voluntarily converted all $ 477 million aggregate principal amount of the New Convertible Notes for approximately 41.8 million shares of the Company’s common stock. Upon conversion, the Company paid $46 million in cash consisting of early conversion payments to the holders of the notes, as well as all accrued and unpaid interest on such notes. As a result of the conversions , Whiting recognized a $188 million loss on extinguishment of debt, which consisted of a non-cash charge for the acceleration of unamortized debt issuance costs and debt discount on the n otes. As of June 30, 2016, no New Convertible Notes remained outstanding. Exchange of Senior Notes and Senior Subordinated Notes for Mandatory Convertible Notes. On July 1, 2016, the Company completed the exchange of $405 million aggregate principal amount of Whiting Senior Notes and 2018 Senior Subordinated Notes for the same aggregate principal amount of new mandatory convertible senior notes and mandatory convertible senior subordinated notes. Refer to the “Subsequent Events” footnote for more information on these exchange transactions and the terms of the new mandatory convertible notes. Kodiak Senior Notes. In conjunction with the acquisition of Kodiak Oil & Gas Corp. (the “Kodiak Acquisition”) in December 2014 , Whiting US Holding Company, a wholly-owned subsidiary of the Company, became a co-issuer of Kodiak’s $800 million of 8.125% Senior Notes due December 2019 (the “2019 Kodiak Notes”), $350 million of 5.5% Senior Notes due January 2021 (the “2021 Kodiak Notes”), and $400 million of 5.5% Senior Notes due February 2022 (the “2022 Kodiak Notes” and together with the 2019 Kodiak Notes and the 2021 Kodiak Notes, the “Kodiak Notes”). I n January 2015, Whiting offered to repurchase at 101% of par all $1,550 million principal amount of Kodiak Notes then outstanding. I n March 2015, Whiting paid $760 million to repurchase $2 million aggregate principal amount of the 2019 Kodiak Notes, $346 million aggregate principal amount of the 2021 Kodiak Notes and $399 million aggregate principal amount of the 2022 Kodiak Notes, which payment consisted of the 101% redemption price and all accrued and unpaid interest on such notes. I n May 2015, Whiting paid an additional $5 million to repurchase the remaining $4 million aggregate principal amount of the 2021 Kodiak Notes and $1 million aggregate principal amount of the 2022 Kodiak Notes, which payment consisted of the 101% redemption price and all accrued and unpaid interest on such notes. I n December 2015, Whiting paid $834 million to repurchase the remaining $798 million aggregate principal amount of the 2019 Kodiak Notes, which payment consisted of the 104.063% redemption price and all accrued and unpaid interest on such notes. As a result of the repurchases, Whiting recognized a n $18 million loss on extinguishment of debt, which consisted of a $40 million cash charge related to the redemption premium on the Kodiak Notes, partially offset by a $22 million non-cash credit related to the acceleration of unamortized debt premiums on such notes. As of December 31, 2015, no Kodiak Notes remained outstanding. 2020 Convertible Senior Notes —In March 2015, the Company issued at par $1,250 million of 1.25% Convertible Senior Notes due April 2020 (the “ 2020 Convertible Senior Notes” ) f or net proceeds of $1.2 billion, net of initial purchasers’ fees of $25 million. The notes will mature on April 1, 2020 unless earlier converted in accordance with their terms. On June 29, 2016, the Company exchanged $129 million aggregate principal amount of its 2020 Convertible Senior Notes for the same aggregate principal amount of new mandatory convertible senior notes, and on July 1, 2016, the Company exchanged $559 million aggregate principal amount of its 2020 Convertible Senior Notes for the same aggregate principal amount of new mandatory convertible senior notes. Refer to “Exchange of 2020 Convertible Senior Notes for Mandatory Convertible Senior Notes” below and the “Subsequent Events” footnote for more information on these exchange transactions and the terms of the new mandatory convertible notes. For the remaining $ 562 million aggregate principal amount of 2020 Convertible Senior Notes, t he Company has the option to settle conversions of these notes with cash, shares of common stock or a combination of cash and common stock at its election. The Company’s intent is to settle the principal amount of the 2020 Convertible Senior Notes in cash upon conversion. Prior to January 1, 2020, the 2020 Convertible Senior Notes will be convertible at the holder’s option only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2015 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the 2020 Convertible Senior Notes for each trading day of the measurement period is less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; or (iii) upon the occurrence of specified corporate events. On or after January 1, 2020, the 2020 Convertible Senior Notes will be convertible at any time until the second scheduled trading day immediately preceding the April 1, 2020 maturity date of the notes. The notes will be convertible at an initial conversion rate of 25.6410 shares of Whiting’s common stock per $1,000 principal amount of the notes, which is equivalent to an initial conversion price of approximately $39.00 . The conversion rate will be subject to adjustment in some events. In addition, following certain corporate events that occur prior to the maturity date, the Company will increase, in certain circumstances, the conversion rate for a holder who elects to convert its 2020 Convertible Senior Notes in connection with such corporate event. As of June 30, 2016 , none of the contingent conditions allowing holders of the 2020 Convertible Senior Notes to convert these notes had been met. Upon issuance, the Company separately accounted for the liability and equity components of the 2020 Convertible Senior Notes. The liability component was recorded at the estimated fair value of a similar debt instrument without the conversion feature. The difference between the principal amount of the 2020 Convertible Senior Notes and the estimated fair value of the liability component was recorded as a debt discount and is being amortized to interest expense over the term of the notes using the effective interest method, with an effective interest rate of 5.6% per annum. The fair value of the 2020 Convertible Senior Notes as of the issuance date was estimated at $1.0 billion, resulting in a debt discount at inception of $238 million. The equity component, representing the value of the conversion option, was computed by deducting the fair value of the liability component from the initial proceeds of the 2020 Convertible Senior Notes issuance. This equity component was recorded, net of deferred taxes and issuance costs, in additional paid-in capital within shareholders’ equity, and will not be remeasured as long as it continues to meet the conditions for equity classification. Transaction costs related to the 2020 Convertible Senior Notes issuance were allocated to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component were recorded as a reduction to the carrying value of long-term debt on the consolidated balance sheet and are being amortized to expense over the term of the notes using the effective interest method. Issuance costs attributable to the equity component were recorded as a charge to additional paid-in capital within shareholders’ equity. The 2020 Convertible Senior Notes consist of the following at June 30, 2016 and December 31, 2015 (in thousands): June 30, December 31, 2016 2015 Liability component: Principal $ 1,121,465 $ 1,250,000 Less: unamortized note discount (164,941) (205,572) Less: unamortized debt issuance costs (13,731) (17,277) Net carrying value $ 942,793 $ 1,027,151 Equity component (1) $ 217,412 $ 237,500 (1) Recorded in additional paid-in capital, net of $5 million of issuance costs and $78 million of deferred taxes as of June 30, 2016 and $ 5 million of issuance costs and $88 million of deferred taxes as of December 31, 2015 . The following table presents the i nterest expense recognized on the 2020 Convertible Senior Notes related to the stated interest rate and amortization of the debt discount for the three and six months ended June 30, 2016 and 2015 (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Interest expense on 2020 Convertible Senior Notes $ 14,630 $ 14,250 $ 29,323 $ 14,881 Exchange of 2020 Convertible Senior Notes for Mandatory Convertible Senior Notes. On June 29, 2016, the Company completed the exchange of $129 million aggregate principal amount of its 2020 Convertible Senior Notes for the same aggregate principal amount of new mandatory convertible senior notes (the “2020 Mandatory Convertible Notes, Series 2” and together with the 2020 Convertible Senior Notes, the “Convertible Senior Notes”). The redemption provisions, covenants , interest payments and maturity terms of the 2020 Mandatory Convertible Notes , Series 2 are substantially identical to those applicable to the 2020 Convertible Senior Notes except that the 2020 Mandatory Convertible Notes, Series 2 will mature on June 5, 2020 unless earlier converted in accordance with their terms. This transaction was accounted for as an extinguishment of debt for the portion of the 2020 Convertible Senior Notes that were exchanged. As a result, Whiting recognized a $9 million gain on extinguishment of debt, which was net of a $21 million non-cash write-off of unamortized debt issuance costs and debt discount on the original notes. In addition, Whiting recorded a $10 million reduction to the equity component of the 2020 Convertible Senior Notes, which is net of deferred taxes. The 2020 Mandatory Convertible Notes , Series 2 were recorded at fair value upon issuance, with the difference between the principal amount of the notes and their fair value, totaling $10 million, recorded as a debt discount. Accrued transaction costs of $2 million attributable to this note issuance were recorded as a reduction to the carrying value of long-term debt on the consolidated balance sheet and are being amortized to interest expense over the term of the notes using the effective interest method. The 2020 Mandatory Convertible Notes, Series 2 contain a mandatory conversion feature whereby four percent of the aggregate principal amount of the 2020 Mandatory Convertible Notes , Series 2 will be converted into shares of the Company’s common stock for each day of the 25 trading day period that commenced on June 23, 20 16 (the “Observation Period”) if the daily volume weighted average price (the “Daily VWAP” ) ( as defined in the indentures governing the 2020 Mandatory Convertible Notes , Series 2 ) of the Company’s common stock on such day (rounded to four decimal places) is above $8.7500 (the “Threshold Price”) . If converted, the common stock issue price per share will be equal to the higher of (i) the Daily VWAP for the Company’s c ommon s tock for such trading day multiplied by one plus 8.0% or (ii) $9.45 (equivalent to 105.82 common shares per $1,000 principal amount of the notes) (the “Minimum Conversion Price”) . S ettlements for the 2020 Mandatory Convertible Notes, Series 2 that become convertible into common stock during the Observation Period will occur on the third business day following the Observation Period . If any 2020 Mand atory Convertible Notes , Series 2 remain after the Observation Period, the conversion price for such note s will be the Minimum Conversion Price. After the Observation Period, the Company has the right to mandatorily convert the 2020 Mandatory Convertible Notes , Series 2 if the Daily VWAP of the Company’s c ommon s tock (rounded to four decimal places) exceeds $8.7500 , for at least 20 trading days during a 30 consecutive trading day period after the Observation Period and holders have the right to convert the notes at any time. As of July 26, 2016, the Daily VWAP of the Company’s common stock was above the Threshold Price for 8 of the first 23 trading days during the Observation Period and $41 million aggregate principal amount of the 2020 Mandatory Convertible Notes, Series 2 will convert into approximately 4.0 million shares of the Company’s common stock upon settlement of those conversions. The Whiting Senior Notes and the Convertible Senior Notes a re unsecured obligations of Whiting Petroleum Corporation and these unsecured obligations are subordinated to all of the Company’s secured indebtedness, which consists of Whiting Oil and Gas’ credit agreement. The 2018 Senior Subordinated Notes are also unsecured obligations of Whiting Petroleum Corporation and are subordinated to all of the Company’s senior debt, which currently consists of the Whiting Senior Notes , the Convertible Senior Notes and borrowings under Whiting Oil and Gas’ credit agreement. The Company’s obligations under the Whiting Senior Notes, the Convertible Senior Notes and the 2018 Senior Subordinated Note s are guaranteed by the Company’s 100% -owned subsidiaries, Whiting Oil and Gas, Whiting US Holding Company, Whiting Canadian Holding Company ULC and Whiting Resources Corporation (the “Guarantors”). These guarantees are full and unconditional and joint and several among the Guarantors. Any subsidiaries other than these Guarantors are minor subsidiaries as defined by Rule 3-10(h)(6) of Regulation S ‑X of the SEC. Whiting Petroleum Corporation has no assets or operations independent of this debt and its investments in its consolidated subsidiaries. |

ASSET RETIREMENT OBLIGATIONS [Abstract] | |
ASSET RETIREMENT OBLIGATIONS | 5 . ASSET RETIREMENT OBLIGATIONS The Company’s asset retirement obligations represent the present value of estimated future costs associated with the plugging and abandonment of oil and gas wells, removal of equipment and facilities from leased acreage, and land restoration (including removal of certain onshore and offshore facilities in California) in accordance with applicable local, state and federal laws. The Company follows FASB ASC Topic 410, Asset Retirement and Environmental Obligations , to determine its asset retirement obligation amounts by calculating the present value of the estimated future cash outflows associated with its plug and abandonment obligations. The current portions at June 30, 2016 and December 31, 2015 were $8 million and $6 million, respectively, and have been included in accrued liabilities and other. Revisions to the liability typically occur due to changes in estimated abandonment costs or well economic lives, or if federal or state regulators enact new requirements regarding the abandonment of wells. The following table provides a reconciliation of the Company’s asset retirement obligations for the six months ended June 30, 2016 (in thousands): Asset retirement obligation at January 1, 2016 $ 161,908 Additional liability incurred 850 Revisions to estimated cash flows 5,441 Accretion expense 7,232 Obligations on sold properties (425) Liabilities settled (3,911) Asset retirement obligation at June 30, 2016 $ 171,095 |

DERIVATIVE FINANCIAL INSTRUMENTS [Abstract] | |
DERIVATIVE FINANCIAL INSTRUMENTS | 6 . DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risks relating to its ongoing business operations, and it uses derivative instruments to manage its commodity price risk. In addition, the Company had convertible notes that contained embedded conversion options which were required to be accounted for as derivatives. Whiting follows FASB ASC Topic 815, Derivatives and Hedging , to account for its derivative financial instruments. Commodity Derivative Contracts — Historically, prices received for crude oil and natural gas production have been volatile because of supply and demand factors, worldwide political factors, general economic conditions and seasonal weather patterns. Whiting enters into derivative contracts such as costless collars and crude oil sales and delivery contracts to achieve a more predictable cash flow by reducing its exposure to commodity price volatility. Commodity derivative contracts are thereby used to ensure adequate cash flow to fund the Company’s capital programs and to manage returns on drilling programs and acquisitions. The Company does not enter into derivative contracts for speculative or trading purposes. Crude Oil Costless Collars. Costless collars are designed to establish floor and ceiling prices on anticipated future oil or gas production. While the use of these derivative instruments limits the downside risk of adverse price movements, they may also limit future revenues from favorable price movements. The table below details the Company’s costless collar derivatives entered into to hedge forecasted crude oil production revenues as of July 1, 2016 . Whiting Petroleum Corporation Derivative Contracted Crude Weighted Average NYMEX Price Instrument Period Oil Volumes (Bbl) Collar Ranges for Crude Oil (per Bbl) Three-way collars (1) Jul - Dec 2016 8,400,000 $43.75 - $53.75 - $74.40 Jan - Dec 2017 6,000,000 $33.00 - $43.50 - $61.75 Collars Jul - Dec 2016 1,500,000 $51.00 - $63.48 Jan - Dec 2017 3,000,000 $53.00 - $70.44 Total 18,900,000 (1) A three-way collar is a combination of options: a sold call, a purchased put and a sold put. The sold call establishes a maximum price (ceiling) Whiting will receive for the volumes under contract. The purchased put establishes a minimum price (floor), unless the market price falls below the sold put (sub-floor), at which point the minimum price would be NYMEX plus the difference between the purchased put and the sold put strike price. Crude Oil Sales and Delivery Contract. The Company has a long-term crude oil sales and delivery contract for oil volumes produced from its Redtail field in Colorado. Under the terms of the agreement, Whiting has committed to deliver certain fixed volumes of crude oil through 2020. The Company determined that it was not probable that future oil production from its Redtail field would be sufficient to meet the minimum volume requirement s specified in this contract, and accordingly, that the Company would not settle this contract through physical delivery of crude oil volumes. As a result, Whiting determined that this contract would not qualify for the “normal purchase normal sale” exclusion and has therefore reflected the contract at fair value in the consolidated financial statements. As of June 30, 2016 , the estimated fair value of this derivative contract was a liability of $10 million. Embedded Derivative s — In March 2016, the Company issued convertible notes that contained debt holder conversion options which the Company determined were not clearly and closely related to the debt host contracts, and the Company therefore bifurcated these embedded features and reflected them at fair value in the consolidated financial statements. As of June 30 , 2016 , the entire aggregate principal amount of these notes had been converted into shares of the Company’s common stock, and t he fair value of these embedded derivatives was therefore zero . Derivative Instrument Reporting — All derivative instruments are recorded in the consolidated financial statements at fair value, other than derivative instruments that meet the “normal purchase normal sale” exclusion or other derivative scope exceptions . The following table s summarize the effects of derivative instruments on the consolidated statements of operations for the three and six months ended June 30, 2016 and 2015 (in thousands): (Gain) Loss Recognized in Income Not Designated as Statement of Operations Six Months Ended June 30, ASC 815 Hedges Classification 2016 2015 Commodity contracts Derivative (gain) loss, net $ 49,965 $ 92,568 Embedded derivatives Derivative (gain) loss, net (47,965) - Total $ 2,000 $ 92,568 (Gain) Loss Recognized in Income Not Designated as Statement of Operations Three Months Ended June 30, ASC 815 Hedges Classification 2016 2015 Commodity contracts Derivative (gain) loss, net $ 66,711 $ 102,419 Embedded derivatives Derivative (gain) loss, net (69,472) - Total $ (2,761) $ 102,419 Offsetting of Derivative Assets and Liabilities. The Company nets its financial derivative instrument fair value amounts executed with the same counterparty pursuant to ISDA master agreements, which pr ovide for net settlement over the term of the contract and in the event of default or termination of the contract. The following tables summarize the location and fair value amounts of all the Company’s derivative instruments in the consolidated balance sheets, as well as the gross recognized derivative assets, liabilities and amounts offset in the consolidated balance sheets (in thousands): June 30, 2016 (1) Net Gross Recognized Recognized Gross Fair Value Not Designated as Assets/ Amounts Assets/ ASC 815 Hedges Balance Sheet Classification Liabilities Offset Liabilities Derivative assets: Commodity contracts - current Derivative assets $ 74,320 $ (25,118) $ 49,202 Commodity contracts - non-current Other long-term assets 23,240 (17,744) 5,496 Total derivative assets $ 97,560 $ (42,862) $ 54,698 Derivative liabilities: Commodity contracts - current Accrued liabilities and other $ 28,014 $ (25,118) $ 2,896 Commodity contracts - non-current Other long-term liabilities 26,274 (17,744) 8,530 Total derivative liabilities $ 54,288 $ (42,862) $ 11,426 December 31, 2015 (1) Net Gross Recognized Recognized Gross Fair Value Not Designated as Assets/ Amounts Assets/ ASC 815 Hedges Balance Sheet Classification Liabilities Offset Liabilities Derivative assets: Commodity contracts - current Derivative assets $ 258,778 $ (100,049) $ 158,729 Commodity contracts - non-current Other long-term assets 31,415 (3,465) 27,950 Total derivative assets $ 290,193 $ (103,514) $ 186,679 Derivative liabilities: Commodity contracts - current Accrued liabilities and other $ 101,214 $ (100,049) $ 1,165 Commodity contracts - non-current Other long-term liabilities 6,327 (3,465) 2,862 Total derivative liabilities $ 107,541 $ (103,514) $ 4,027 (1) Because counterparties to the Company’s financial derivative contracts subject to master netting arrangements are lenders under Whiting Oil and Gas’ credit agreement, which eliminates its need to post or receive collateral associated with its derivative positions, columns for cash collateral pledged or received have not been presented in the se tables. Contingent Features in Financial Derivative Instruments . None of the Company’s derivative instruments contain credit-risk-related contingent features. Counterparties to the Company’s financial derivative contracts are high credit-quality financial institutions that are lenders under Whiting’s credit agreement. The Company uses only credit agreement participants to hedge with, since these institutions are secured equally with the holders of Whiting’s bank debt, which eliminates the potential need to post collateral when Whiting is in a derivative liability position. As a result, the Company is not required to post letters of credit or corporate guarantees for its derivative counterparties in order to secure contract performance obligations. |

FAIR VALUE MEASUREMENTS [Abstract] | |
FAIR VALUE MEASUREMENTS | 7 . FAIR VALUE MEASUREMENTS The Company follows FASB ASC Topic 820, Fair Value Measurement and Disclosure , which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows: · Level 1: Quoted Prices in Active Markets for Identical Assets – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. · Level 2: Significant Other Observable Inputs – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. · Level 3: Significant Unobservable Inputs – inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s categorization within the valuation hierarchy is based upon 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 in its entirety requires judgment and considers factors specific to the asset or liability. 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. Cash and cash equivalents, accounts receivable and accounts payable are carried at cost, which approximates their fair value because of the short-term maturity of these instruments. The Company’s credit agreement has a recorded value that approximates its fair value since its variable interest rate is tied to current market rates. The Company’s senior n otes and senior subordinated n otes are recorded at cost , and the Company’s convertible senior notes are recorded at fair value at the date of issuance . The following table summarizes the fair values and carrying values of these instruments as of June 30, 2016 and December 31, 2015 (in thousands): June 30, 2016 December 31, 2015 Fair Carrying Fair Carrying Value Value Value Value 6.5% Senior Subordinated Notes due 2018 (1) $ 286,224 $ 299,051 $ 265,125 $ 346,876 5% Senior Notes due 2019 (1) 912,901 997,121 830,500 1,092,219 1.25% Convertible Senior Notes due 2020 (1) 885,957 942,793 850,000 1,027,151 1.25% Mandatory Convertible Senior Notes due 2020, Series 2 (2) 117,022 117,310 - - 5.75% Senior Notes due 2021 (1) 949,318 1,040,877 870,000 1,191,861 6.25% Senior Notes due 2023 (1) 511,276 563,769 543,750 739,597 Total $ 3,662,698 $ 3,960,921 $ 3,359,375 $ 4,397,704 (1) Fair values are based on quoted market prices for these debt securities, and such fair values are therefore designated as Level 1 within the valuation hierarchy. (2) Fair value is determined using a binomial lattice model which considers various inputs including (i) Whiting’s common stock price, (ii) risk-free rates based on U.S. Treasury rates, (iii) recovery rates in the event of default, (iv) default intensity, and (v) volatility of Whiting’s common stock. The expected volatility and default intensity used in the valuation are unobservable in the marketplace and significant to the valuation methodology, and such fair value is therefore designated as Level 3 within the valuation hierarchy. The Company’s derivative financial instruments are recorded at fair value and include a measure of the Company’s own nonperformance risk or that of its counterpart y , as appropriate. The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2016 and December 31, 2015 , and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair values (in thousands): Total Fair Value Level 1 Level 2 Level 3 June 30, 2016 Financial Assets Commodity derivatives – current $ - $ 49,202 $ - $ 49,202 Commodity derivatives – non-current - 5,496 - 5,496 Total financial assets $ - $ 54,698 $ - $ 54,698 Financial Liabilities Commodity derivatives – current $ - $ - $ 2,896 $ 2,896 Commodity derivatives – non-current - 1,542 6,988 8,530 Total financial liabilities $ - $ 1,542 $ 9,884 $ 11,426 Total Fair Value Level 1 Level 2 Level 3 December 31, 2015 Financial Assets Commodity derivatives – current $ - $ 158,729 $ - $ 158,729 Commodity derivatives – non-current - 27,950 - 27,950 Total financial assets $ - $ 186,679 $ - $ 186,679 Financial Liabilities Commodity derivatives – current $ - $ - $ 1,165 $ 1,165 Commodity derivatives – non-current - - 2,862 2,862 Total financial liabilities $ - $ - $ 4,027 $ 4,027 The following methods and assumptions were used to estimate the fair values of the Company’s financial assets and liabilities that are measured on a recurring basis: Commodity Derivatives . Commodity derivative instruments consist mainly of costless collars for crude oil. The Company’s costless collars are valued based on an income approach. T he option model consider s various assumptions, such as quoted forward prices for commodities, time value and volatility factors. These assumptions are observable in the marketplace throughout the full term of the contract, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace, and are therefore designated as Level 2 within the valuation hierarchy. The discount rates used in the fair values of these instruments include a measure of either the Company’s or the counterparty’s nonperformance risk, as appropriate. The Company utilizes its counterparties’ valuations to assess the reasonableness of its own valuations. In addition, the Company has a long-term crude oil sales and delivery contract, whereby it has committed to deliver certain fixed volumes of crude oil through 2020. Whiting has determined that the contract does not meet the “normal purchase normal sale” exclusion, and has therefore reflected this contract at fair value in its consolidated financial statements. This commodity derivative was valued based on an income approach which considers various assumptions, including quoted forward prices for commodities, market differentials for crude oil, U.S. Treasury rates and either the Company’s or the counterparty’s nonperformance risk, as appropriate. The assumptions used in the valuation of the crude oil sales and delivery contract include certain market differential metrics that were unobservable during the term of the contract. Such unobservable inputs were significant to the contract valuation methodology, and the contract’s fair value was therefore designated as Level 3 within the valuation hierarchy. Embedded Derivatives . The Company had em bedded derivatives related to its convertible notes that were issued in March 2016. The notes contained debt holder conversion options which the Company determined were not clearly and closely related to the debt host contracts and the Company therefore bifurcated these embedded features and reflected them at fair value in the consolidated financial statements . Prior to their settlements, the fair values of these embedded derivatives were determined using a binomial lattice model which considered various inputs including (i) Whiting’s common stock price, (ii) risk-free rates based on U.S. Treasury rates, (iii) recovery rates in the event of default, (iv) default intensity, and (v) volatility of Whiting’s common stock. The expected volatility and default intensity used in the valuation were unobservable in the marketplace and significant to the valuation methodology, and the embedded derivatives’ fair value was therefore designated as Level 3 in the valuation hierarchy. During the second quarter of 2016, the entire aggregate principal amount of these convertible notes was converted into shares of the Company’s common stock, and these embedded derivatives were thereby settled in their entirety as of June 30, 2016. Level 3 Fair Value Measurements — A third-party valuation specialist is utilized to determine the fair value of the Company’s derivative instruments designated as Level 3. The Company reviews these valuations , including the related model inputs and assumptions , and analyzes changes in fair value measurements between periods. The Company corroborates such inputs, calculations and fair value changes using various methodologies, and reviews unobservable inputs for reasonableness utilizing relevant information from other published sources. T he following table presents a reconciliation of changes in the fair value of financial assets or liabilities designated as Level 3 in the valuation hierarchy for the three and six months ended June 30, 2016 and 2015 (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Fair value asset (liability), beginning of period $ (118,627) $ 35,786 $ (4,027) $ 53,530 Recognition of embedded derivatives associated with convertible note issuances - - (89,884) - Unrealized losses on commodity derivative contracts included in earnings (1) (2,648) (43,327) (5,857) (61,071) Unrealized gains on embedded derivatives included in earnings (1) 69,472 - 47,965 - Settlement of embedded derivatives upon conversion of convertible notes 41,919 - 41,919 - Transfers into (out of) Level 3 - - - - Fair value liability, end of period $ (9,884) $ (7,541) $ (9,884) $ (7,541) (1) Included in derivative (gain) loss, net in the consolidated statements of operations. Quantitative Information About Level 3 Fair Value Measurements. The significant unobservable inputs used in the fair value measurement of the Company’s derivative instrument designated as Level 3 are as follows: Derivative Instrument Valuation Technique Unobservable Input Amount Commodity derivative contract Income approach Market differential for crude oil $4.91 per Bbl Sensitivity to Changes In Significant Unobservable Inputs. As presented above, the significant unobservable inputs used in the fair value measurement of Whiting’s commodity derivative contract are the market differentials for crude oil over the term of the contract. Significant increases or decreases in these unobservable inputs in isolation would result in a significantly higher or lower, respectively, fair value liability measurement. 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. These assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. The Company did not recognize any impairment write-downs with respect to its proved property during the 2016 or 2015 reporting periods presented. |

SHAREHOLDERS' EQUITY AND NONCONTROLLING INTEREST [Abstract] | |
SHAREHOLDERS' EQUITY AND NONCONTROLLING INTEREST | 8 . SHAREHOLDERS ’ EQUITY AND NONCONTROLLING INTEREST Common Stock — In May 2016, Whiting’s shareholders approved an amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 300,000,000 to 600,000,000 shares. Common Stock Offering . In March 2015, the Company completed a public offering of its common stock, selling 35,000,000 shares of common stock at a price of $30.00 per share and providing net proceeds of approximately $1.0 billion after underwriter’s fees. In addition, the Company granted the underwriter a 30 -day option to purchase up to an additional 5,250,000 shares of common stock. On April 1, 2015 , the underwriter exercised its right to purchase an additional 2,000,000 shares of common stock, providing additional net proceeds of $61 million. Equity Incentive Plan —At the Company’s 2013 Annual Meeting held on May 7, 2013, shareholders approved the Whiting Petroleum Corporation 2013 Equity Incentive Plan (the “2013 Equity Plan”), which replaced the Whiting Petroleum Corporation 2003 Equity Incentive Plan (the “2003 Equity Plan”) and include d the authority to issue 5,300,000 shares of the Company’s common stock. Upon shareholder approval of the 2013 Equity Plan, the 2003 Equity Plan was terminated. The 2003 Equity Plan continues to govern awards that were outstanding as of the date of its termination, which remain in effect pursuant to their terms. Any shares netted or forfeited after May 7, 2013 under the 2003 Equity Plan and any shares forfeited under the 2013 Equity Plan will be available for future issuance under the 2013 Equity Plan. However, shares netted for tax withholding under the 2013 Equity Plan will be cancelled and will not be available for future issuance. On December 8, 2014, the Company increased the number of shares issuable under the 2013 Equity Plan by 978,161 shares to accommodate for the conversion of Kodiak’s outstanding equity awards to Whiting equity awards upon closing of the Kodiak Acquisition. Any shares netted or forfeited under this increased availability will be cancelled and will not be available for future issuance under the 2013 Equity Plan. At the Company’s 2016 Annual Meeting held on May 17, 2016, shareholders approved an amendment and restatement of the 2013 Equity Plan which increased the total number of shares issuable under the plan by 5,500,000 and revised certain award limits for employees and non-employee directors. Under the amended 2013 Equity Plan , no employee or officer participant may be granted options for more than 900,000 shares of common stock, stock appreciation rights relating to more than 900,000 shares of common stock, or more than 600,000 shares of restricted stock during any calendar year. In addition, no non-employee director participant may be granted options for more than 100,000 shares of common stock, stock appreciation rights relating to more than 1 00,000 shares of common stock, or more than 1 00,000 shares of restricted stock during any calendar year. As of June 30, 2016 , 6,208,068 shares of common stock remained available for grant under the amended 2013 Equity Plan. Noncontrolling Interest —The Company’s noncontrolling interest represents an unrelated third party’s 25% ownership interest in Sustainable Water Resources, LLC. The table below summarizes the activity for the equity attributable to the noncontrolling interest (in thousands): Six Months Ended June 30, 2016 2015 Balance at beginning of period $ 7,984 $ 8,070 Net loss (15) (38) Balance at end of period $ 7,969 $ 8,032 |

INCOME TAXES [Abstract] | |
INCOME TAXES | 9 . INCOME TAXES Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items which are recorded in the interim period. The provision for income taxes for the three and six months ended June 30, 2016 and 2015 differs from the amount that would be provided by applying the statutory U.S. federal income tax rate of 35% to pre-tax income primarily because of state income taxes and estimated permanent differences. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is obtained, additional information becomes known or as the tax environment changes. |

In addition , the diluted earnings per share calculation for the three months ended June 30, 2016 excludes the dilutive effect of 1,452,753 common shares for stock options that were out-of-the-money and 641,636 shares of restricted stock that did not meet its market-based vesting criteria as of June 30 , 2016 . During the three months ended June 30, 2015, the Company had a net loss and therefore the diluted earnings per share calculation for that period excludes the anti-dilutive effect of 406,986 shares of restricted stock and 96,767 stock options. In addition, the diluted earnings per share calculation for the three months ended June 30, 2015 excludes (i) the anti-dilutive effect of 764,827 incremental shares of restricted stock that did not meet its market-based vesting criteria as of June 30, 2015 and (ii) the dilutive effect of 251,040 common shares for stock options that were out-of-the-money. During the six months ended June 30, 2016 , the Company had a net loss and therefore the diluted earnings per share calculation for that period excludes the anti-dilutive effect of (i) 955,774 shares of service-based restricted stock, (ii) 146,509 shares issuable upon conversion of the 2020 Mandatory Convertible Notes, Series 2, and (iii) 4,630 stock options. In addition, the diluted earnings per share calculation for the six months ended June 30, 2016 excludes the dilutive effect of 2,024,354 common shares for stock options that were out-of-the-money and 561,313 shares of restricted stock that did not meet its market-based vesting criteria as of June 30 , 2016 . During the six months ended June 30, 2015, the Company had a net loss and therefore the diluted earnings per share calculation for that period excludes the anti-dilutive effect of 479,975 shares of restricted stock and 107,286 stock options. In addition, the diluted earnings per share calculation for the six months ended June 30, 2015 excludes (i) the anti-dilutive effect of 756,376 incremental shares of restricted stock that did not meet its market-based vesting criteria as of June 30, 2015 and (ii) the dilutive effect of 287,382 common shares for stock options that were out-of-the-money. As discussed in the “Long-Term Debt” footnote, the Company has the option to settle the 2020 Convertible Senior Notes with cash, shares of common stock or any combination thereof upon conversion. The Company’s intent is to settle the principal amount of the 2020 Convertible Senior Notes in cash upon conversion. As a result, only the amount by which the conversion value exceeds the aggregate principal amount of the notes (the “conversion spread”) is considered in the diluted earnings per share computation under the treasury stock method. As of June 30, 2016 , the conversion value did not exceed the principal amount of the notes, and accordingly, there was no impact to diluted earnings per share or the related disclosures for th ose period s . |

COMMITMENTS AND CONTINGENCIES | 11. COMMITMENTS AND CONTINGENCIES During the second quarter of 2016, the Company terminated two ship-or-pay agreements that expired in 2026, and incurred termination penalties totaling $1 million. Under the original agreements, the Company had committed to transport a minimum daily volume of crude oil or water, as the case may be, via certain pipelines or else pay for any deficiencies at prices stipulated in the contracts. The termination of these agreements reduced the Company’s future commitments under this agreement by approximately $67 million as of June 30, 2016. As discussed below in the “Subsequent Events” footnote, the Company sold its interest in the North Ward Estes field in Texas on July 27, 2016. In conjunction with this sale, the Company transferred to the buyer of the properties (i) a take-or-pay purchase agreement that expires in 2017 to buy certain volumes of CO 2 for use in the North Ward Estes EOR project, and (ii) a ship-or-pay agreement that expires in 2017 to transport a minimum daily volume of CO 2 via certain pipelines. The transfer of these agreements reduced the Company’s future commitments under these contracts by approximately $51 million as of June 30, 2016. |

ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS | 1 2 . ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Improvements To Employee Share-Based Payment Accounting (“ASU 2016-09”). The objective of this ASU is to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Portions of this ASU must be applied prospectively while other portions may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements of adopting ASU 201 6 ‑0 9 . In March 2016, the FASB issued Accounting Standards Update No. 2016-06, Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”). This ASU clarifies the requirements to assess whether an embedded put or call option is clearly and closely related to the debt host, solely in accordance with the four-step decision sequence in FASB ASC Topic 815, Derivatives and Hedging , as amended by ASU 2016-06. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 and should be applied using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 201 6 ‑0 6, however the standard is not expected to have a significant effect on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (“ASU 2016-02”). The objective of this ASU is to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 201 6 - 02 is effective for fiscal years , and interim periods within those fiscal years , beginning after December 15, 201 8 and should be applied using a modified retrospective approach . Early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements of adopting ASU 201 6 ‑0 2 . In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This ASU amends the guidance in U.S. GAAP on financial instruments specifically related to (i) the classification and measurement of investments in equity securities, (ii) the presentation of certain fair value changes for financial liabilities measured at fair value and (iii) certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted only for the provisions of this ASU related to FASB ASC 825, Financial Instruments . A cumulative-effect adjustment to beginning retained earnings is required as of the beginning of the fiscal year in which this ASU is adopted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). This ASU eliminates the requirement to retrospectively apply measurement-period adjustments made to provisional amounts recognized in a business combination. Under ASU 2015-16, the cumulative impact of a measurement-period adjustment (including the impact on prior periods) should instead be recognized in the reporting period in which the adjustment is identified. ASU 2015-16 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. This standard should be applied prospectively, and early adoption is permitted. The Company adopted ASU 2015-16 effective January 1, 2016, which did not have an impact on the Company’s financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). This ASU requires entities to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted. The adoption of this standard will not have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”). The objective of ASU 2014-15 is to provide guidance on management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for fiscal years ending after December 15, 2016 and annual and interim periods thereafter. This standard is not expected to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014 ‑09”). The objective of ASU 2014-09 is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The FASB subsequently issued ASU 2015-14, ASU 2016-08, ASU 2016-10 and ASU 2016-12, which deferred the effective date of ASU 2014-09 and provided additional implementation guidance. These ASUs are effective for fiscal years, and interim periods within those years, beginning after December 31, 2017. The standards permit retrospective application using either of the following methodologies: (i) restatement of each prior reporting period presented or (ii) recognition of a cumulative-effect adjustment as of the date of initial application. The Company is currently evaluating the imp act of adopting these standards on its consolidated financial statements , as well as the transition method to be applied . |

SUBSEQUENT EVENTS [Abstract] | |
SUBSEQUENT EVENTS | 1 3 . SUBSEQUENT EVENTS Note Exchanges — O n July 1, 2016, the Company completed the exchange of $964 million aggregate principal amount of its senior notes, convertible senior notes and senior subordinated notes, consisting of (i) $26 million aggregate principal amount of its 2018 Senior Subordinated Notes, (ii) $42 million aggregate principal amount of its 2019 Senior Notes, (iii) $559 million aggregate principal amount of its 2020 Convertible Senior Notes, (iv) $174 million aggregate principal amount of its 2021 Senior Notes , and (v) $163 million aggregate principal amount of its 2023 Senior Notes , for (i) $26 million aggregate principal amount of new 6.5% Mandatory Convertible Senior Subordinated Notes due 2018 (the “2018 Mandatory Convertible Notes”), (ii) $42 million aggregate principal amount of new 5% Mandatory Convertible Senior Notes due 2019 (the “2019 Mandatory Convertible Note s”), (iii) $559 million aggregate principal amount of new 1.25% Mandatory Convertible Senior Notes due 2020, Series 1 (the “2020 Mandatory Convertible Notes, Series 1”), (iv) $174 million aggregate p rincipal amount of new 5.75% Mandatory Convertible Senior Notes due 2021 (the “202 1 Mandatory Convertible Notes”), and (v) $163 million aggregate principal amount of new 6.25% Mandatory Convertible Senior Notes due 2023 (the “2023 Mandatory Convertible Notes” and, together with the 2018 Mandatory Convertible Notes, the 2019 Mandatory Convertible Notes , the 2020 Mandatory Convertible Notes, Series 1 and the 2021 Mandatory Convertible Notes, the “ Mandatory Convertible Notes”). The redemption provisions, covenants, interest payments and maturity terms applicable to each series of Mandatory Convertible Notes are substantially identical to those applicable to the corresponding series of Whiting Senior Notes, 2020 Convertible Senior Notes and 2018 Senior Subordinated Notes except that the 2020 Mandatory Convertible Notes, Series 1 will mature on June 5, 2020 unless earlier converted in accordance with their terms. The Mandatory Convertible Notes contain mandatory conversion features whereby four percent of the aggregate principal amount of the Mandatory Convertible Notes will be converted into shares of the Company’s common stock for each day of the 25 trading day period that commenced on June 23, 20 16 (the “Observation Period”) if the daily volume weighted average price (the “Daily VWAP” ) ( as defined in the indentures governing the Mandatory Convertible Notes) of the Company’s common stock on such day , rounded to four decimal places for the 2020 Mandatory Convertible Notes, Series 1 and rounded to two decimal places for the 2018 Mandatory Convertible Notes, the 2019 Mandatory Convertible Notes, the 2021 Mandatory Convertible Notes and the 2023 Mandatory Convertible Notes, is above $8.75 (the “Threshold Price”) . If converted, the common stock issue price per share will be equal to the higher of (i) the Daily VWAP for the Company’s c ommon s tock for such trading day multiplied by one plus zero for the 2018 Mandatory Convertible Notes, one plus 0.5% for the 2019 Mandatory Convertible Notes, one plus 8.0% for the 2020 Mandatory Convertible Notes, Series 1, one plus 2.5% for the 2021 Mandatory Convertible Notes and one plus 3.5% for the 2023 Mandatory Convertible Notes or (ii) $8.75 for the 2018 Mandatory Convertible Notes (equivalent to 114.29 common shares per $1,000 principal amount of the notes), $8.79 for the 2019 Mandatory Convertible Notes (equivalent to 113.72 common shares per $1,000 principal amount of the notes), $9.45 for the 2020 Mandatory Convertible Notes, Series 1 (equivalent to 105.82 common shares per $1,000 principal amount of the notes), $8.97 for the 2021 Mandatory Convertible Notes (equivalent to 111.50 common shares per $1,000 principal amount of the notes) and $9.06 for the 2023 Mandatory Convertible Notes (equivalent to 110.42 common shares per $1,000 principal amount of the notes) (the “Minimum Conversion Price s ”) . S ettlements for the Mandatory Convertible Notes that are converted into common stock during the Observation Period will occur by the third business day following each applicable trading day. If any Mand atory Convertible Notes remain after the Observation Period, the conversion price will be the Minimum Conversion Price for each applicable series of Mandatory Convertible Notes . After the Observation Period, the Company has the right to mandatorily convert the Mandatory Convertible Notes if the Daily VWAP of the Company’s c ommon s tock exceeds the Threshold Price for the applicable series of Mandatory Convertible Notes for at least 20 trading days during a 30 consecutive trading day period after the Observation Period and holders have the right to convert the Mandatory Convertible Notes at any time. As of July 26, 2016, the Daily VWAP of the Company’s common stock was above the Threshold Price (i) for the 2018 Mandatory Convertible Notes, the 2019 Mandatory Convertible Notes, the 2021 Mandatory Convertible Notes and the 2023 Mandatory Convertible Notes, for 7 of the first 23 trading days during the Observation Period and (ii) for the 2020 Mandatory Convertible Notes, Series 1, for 8 of the first 23 trading days during the Observation Period. As a result, $292 million aggregate principal amount of the Mandatory Convertible Notes were converted into approximately 29.1 million shares of the Company’s common stock, and the Company paid $2 million in cash consisting of all accrued and unpaid interest on such notes. The July 1, 2016 note exchange transactions resulted in an ownership change under Section 382 of the Internal Revenue Code and will limit the Company’s usage of certain of its net operating losses in the future. Accordingly, the Company expects to record a material non-cash charge for the write-down of deferred tax assets in the third quarter of 2016, which the Company estimates will be in the range of $500 million to $600 million. Sale of North Ward Estes Properties — On July 27, 2016, the Company completed the sale of its interest in its enhanced oil recovery project in the North Ward Estes field in Ward and Winkler counties of Texas, including Whiting’s interest in certain CO 2 properties in the McElmo Dome field in Colorado, two contracts for the supply and delivery of CO 2 , and certain other related assets and liabilities (the “North Ward Estes Properties”) for a cash purchase price of $300 million (before closing adjustments). In addition to the cash purchase price, the buyer has agreed to pay Whiting $100,000 for every $0.01 that, as of June 28, 2018, the average NYMEX crude oil futures contract price for each month from August 2018 through July 2021 is above $50.00/Bbl up to a maximum amount of $100 million (the “Contingent Payment”). The Contingent Payment will be made at the option of the buyer either in cash on July 31, 2018 or in the form of a secured promissory note, accruing interest at 8% per annum with a maturity date of July 29, 2022. The effective date of the sale is July 1, 2016. The Company expects to record a pre-tax loss on sale for this transaction in the third quarter of 2016, which the Company estimates will be in the range of $ 170 million to $ 200 million. The Company used the net proceeds from the sale to repay a portion of the debt outstanding under its credit agreement. Upon closing of this sale transaction, the borrowing base under Whiting Oil and Gas’ credit agreement was reduced to $2.6 billion, with aggregate commitments of $2.5 billion. The Company determined that the North Ward Estes Properties did not meet the assets held for sale criteria as of June 30, 2016 because, among other factors, the Company’s Board of Directors, having the authority to approve the divestiture, had not done so as of the balance sheet date and (ii) certain contractual arrangements, lessor consents, and credit agreement stipulations were subject to negotiation, ratification and/or amendment such that the North Ward Estes Properties were not available for immediate sale in its present condition and it was not unlikely that significant changes to the divestiture plan would be made, or withdrawn all together, as of June 30, 2016. |

Consolidated Financial Statements | Consolidated Financial Statements —The unaudited consolidated financial statements include the accounts of Whiting Petroleum Corporation and its consolidated subsidiaries. Investments in entities which give Whiting significant influence, but not control, over the investee are accounted for using the equity method. Under the equity method, investments are stated at cost plus the Company’s equity in undistributed earnings and losses. All intercompany balances and transactions have been eliminated upon consolidation. These financial statements have been prepared in accordance with GAAP and the SEC rules and regulations for interim financial reporting. In the opinion of management, the accompanying financial statements include all adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly, in all material respects, the Company’s interim results. However, operating results for the periods presented are not necessarily indicative of the results that may be expected for the full year. The consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q should be read in conjunction with Whiting’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2015 . Except as disclosed herein, there have been no material changes to the information disclosed in the notes to consolidated financial statements included in the Company’s 2015 Annual Report on Form 10 ‑K. |
Earnings Per Share | Earnings Per Share —Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period. Diluted earnings per common share is calculated by dividing adjusted net income available to common shareholders by the weighted average number of diluted common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for the diluted earnings per share calculations consist of (i) convertible debt to be settled in shares only , using the if-converted method and (ii) unvested restricted stock awards, outstanding stock options and contingently issuable shares of convertible debt to be settled in cash, all using the treasury stock method. When a loss from continuing operations exists, all dilutive securities and potentially dilutive securities are anti-dilutive and are therefore excluded from the computation of diluted earnings per share. |

FAIR VALUE MEASUREMENTS [Abstract] | |
Fair Value of Financial Instruments | The Company follows FASB ASC Topic 820, Fair Value Measurement and Disclosure , which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows: · Level 1: Quoted Prices in Active Markets for Identical Assets – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. · Level 2: Significant Other Observable Inputs – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. · Level 3: Significant Unobservable Inputs – inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s categorization within the valuation hierarchy is based upon 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 in its entirety requires judgment and considers factors specific to the asset or liability. 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. Cash and cash equivalents, accounts receivable and accounts payable are carried at cost, which approximates their fair value because of the short-term maturity of these instruments. The Company’s credit agreement has a recorded value that approximates its fair value since its variable interest rate is tied to current market rates. |

ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS [Abstract] | |
Adopted and Recently Issued Accounting Pronouncements | In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Improvements To Employee Share-Based Payment Accounting (“ASU 2016-09”). The objective of this ASU is to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Portions of this ASU must be applied prospectively while other portions may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements of adopting ASU 201 6 ‑0 9 . In March 2016, the FASB issued Accounting Standards Update No. 2016-06, Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”). This ASU clarifies the requirements to assess whether an embedded put or call option is clearly and closely related to the debt host, solely in accordance with the four-step decision sequence in FASB ASC Topic 815, Derivatives and Hedging , as amended by ASU 2016-06. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 and should be applied using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 201 6 ‑0 6, however the standard is not expected to have a significant effect on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (“ASU 2016-02”). The objective of this ASU is to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 201 6 - 02 is effective for fiscal years , and interim periods within those fiscal years , beginning after December 15, 201 8 and should be applied using a modified retrospective approach . Early adoption is permitted. The Company is currently evaluating the impact on its consolidated financial statements of adopting ASU 201 6 ‑0 2 . In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This ASU amends the guidance in U.S. GAAP on financial instruments specifically related to (i) the classification and measurement of investments in equity securities, (ii) the presentation of certain fair value changes for financial liabilities measured at fair value and (iii) certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted only for the provisions of this ASU related to FASB ASC 825, Financial Instruments . A cumulative-effect adjustment to beginning retained earnings is required as of the beginning of the fiscal year in which this ASU is adopted. The adoption of this standard is not expected to have a significant impact on the Company’s consolidated financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). This ASU eliminates the requirement to retrospectively apply measurement-period adjustments made to provisional amounts recognized in a business combination. Under ASU 2015-16, the cumulative impact of a measurement-period adjustment (including the impact on prior periods) should instead be recognized in the reporting period in which the adjustment is identified. ASU 2015-16 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. This standard should be applied prospectively, and early adoption is permitted. The Company adopted ASU 2015-16 effective January 1, 2016, which did not have an impact on the Company’s financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). This ASU requires entities to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted. The adoption of this standard will not have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”). The objective of ASU 2014-15 is to provide guidance on management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for fiscal years ending after December 15, 2016 and annual and interim periods thereafter. This standard is not expected to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014 ‑09”). The objective of ASU 2014-09 is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The FASB subsequently issued ASU 2015-14, ASU 2016-08, ASU 2016-10 and ASU 2016-12, which deferred the effective date of ASU 2014-09 and provided additional implementation guidance. These ASUs are effective for fiscal years, and interim periods within those years, beginning after December 31, 2017. The standards permit retrospective application using either of the following methodologies: (i) restatement of each prior reporting period presented or (ii) recognition of a cumulative-effect adjustment as of the date of initial application. The Company is currently evaluating the imp act of adopting these standards on its consolidated financial statements , as well as the transition method to be applied . |

(2) Fair value is determined using a binomial lattice model which considers various inputs including (i) Whiting’s common stock price, (ii) risk-free rates based on U.S. Treasury rates, (iii) recovery rates in the event of default, (iv) default intensity, and (v) volatility of Whiting’s common stock. The expected volatility and default intensity used in the valuation are unobservable in the marketplace and significant to the valuation methodology, and such fair value is therefore designated as Level 3 within the valuation hierarchy. |

[1] | Fair values are based on quoted market prices for these debt securities, and such fair values are therefore designated as Level 1 within the valuation hierarchy. | ||||||||
[2] | Fair value is determined using a binomial lattice model which considers various inputs including (i) Whiting's common stock price, (ii) risk-free rates based on U.S. Treasury rates, (iii) recovery rates in the event of default, (iv) default intensity, and (v) volatility of Whiting's common stock. The expected volatility and default intensity used in the valuation are unobservable in the marketplace and significant to the valuation methodology, and such fair value is therefore designated as Level 3 within the valuation hierarchy. |
