Business of Presentation [Abstract]	'
Basis of Presentation	'
	Note 1 — Basis of Presentation
	PostRock Energy Corporation is an independent oil and gas company engaged in the acquisition, exploration, development, production and gathering of crude oil and natural gas. Its primary production activity is focused in the Cherokee Basin, a 15-county region in southeastern Kansas and northeastern Oklahoma, and in Central Oklahoma. It also has minor oil and gas producing properties in the Appalachian Basin. Unless the context requires otherwise, references to “PostRock,” the “Company,” “we,” “us” and “our” refer to PostRock Energy Corporation and its consolidated subsidiaries.
	The unaudited interim condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the summary of significant accounting policies and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (the “2013 10-K”).
	The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year.

Derivative Financial Instruments [Abstract]	'
Derivative Financial Instruments	'
	Note 3 — Derivative Financial Instruments
	The Company is exposed to commodity price risk and management believes it prudent to periodically reduce exposure to cash-flow variability resulting from this volatility. Accordingly, the Company enters into certain derivative financial instruments in order to manage exposure to commodity price risk inherent in its oil and gas production. Derivative financial instruments are also used to manage commodity price risk inherent in customer pricing requirements and to fix margins on the future sale of oil and natural gas. Specifically, the Company may utilize futures, swaps and options.
	Derivative instruments expose the Company to counterparty credit risk. The Company’s commodity derivative instruments are currently with two counterparties. The Company generally executes commodity derivative instruments under master agreements which allow it, in the event of default, to elect early termination of all contracts with the defaulting counterparty. If the Company chooses to elect early termination, all asset and liability positions with the defaulting counterparty would be net cash settled at the time of election.
	The Company monitors the creditworthiness of its counterparties; however, it is not able to predict sudden changes in counterparties’ creditworthiness. In addition, even if such changes are not sudden, it may be limited in its ability to mitigate an increase in counterparty credit risk. Possible actions would be to transfer its position to another counterparty or request a voluntary termination of the derivative contracts resulting in a cash settlement. Should one of these counterparties not perform, the Company may not realize the benefit of some of its derivative instruments under lower commodity prices as well as incur a loss. The Company includes a measure of counterparty credit risk in its estimates of the fair values of derivative instruments in an asset position. At March 31, 2014, the Company was a net obligor with respect to outstanding derivative contracts with both of its counterparties and therefore utilized its own credit risk in estimating the fair value of those derivatives.
	The Company does not designate its derivative financial instruments as hedging instruments for financial accounting purposes and, as a result, it recognizes the change in the respective instruments’ fair value currently in earnings. The table below outlines the classification of derivative financial instruments on the condensed consolidated balance sheet and their financial impact on the condensed consolidated statements of operations at and for the periods indicated:

	Unrealized losses		-6,248			-2,608
	Total loss from derivative financial instruments	$	-7,121		$	-5,115
	The Company entered into an International Swap Dealers Association Master Agreement (ISDA) with each of its two counterparties for which it holds derivative contracts. The ISDA is a standard contract that governs all derivative contracts entered into between the Company and the respective counterparty. The ISDA allows for offsetting of amounts payable or receivable between the Company and the counterparty, at the election of both parties, for transactions that occur on the same date and in the same currency. The Company has multiple oil swap contracts that could be offset under these provisions but has elected not to offset the fair values of its derivative assets against the fair value of its derivative liabilities on its condensed consolidated balance sheets. The ISDA also includes a master netting arrangement in the event of early termination or default.
	The following table discloses and reconciles the gross amounts as presented in the condensed consolidated balance sheets to the net amounts allowed under a master netting arrangement.  Amounts not offset on the condensed consolidated balance sheets represent positions that do not meet all the conditions for "a right of offset" or positions for which the Company has elected not to offset.

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	Note 4 — Fair Value Measurements
	Certain assets and liabilities are measured at fair value on a recurring basis in the Company’s condensed consolidated balance sheets. The following methods and assumptions were used to estimate the fair values:
	Cash and Equivalents, Accounts Receivable and Accounts Payable — The carrying amounts approximate fair value due to the short-term nature or maturity of the instruments.
	Commodity Derivative Instruments — The Company’s oil and gas derivative instruments may consist of variable to fixed price swaps, collars and basis swaps. When possible, the Company estimates the fair values of these instruments based on published forward commodity price curves as of the date of the estimate. The discount rate used in the discounted cash flow projections is based on published LIBOR rates adjusted for counterparty credit risk. Counterparty credit risk is incorporated into derivative assets while the Company’s own credit risk is incorporated into derivative liabilities. Both are based on the current published credit default swap rates.
	Investment — The Company has an investment in Constellation Energy Partners LLC (“CEP”), which consisted of 5,503,956 Class B units at March 31, 2014 (see Note 5 —  Investment).  Fair value for the Class B units, which are publicly traded, is based on market price and classified as a Level 1 measurement under the fair value hierarchy. At March 31, 2014, the fair value used for the Class B units was  $2.60 per unit. At December 31, 2013, fair value for the Company’s Class A units was classified as a Level 2 measurement. As of March 31, 2014, the Company no longer held any Class A units (see Note 5 —  Investment).
	The Company classifies assets and liabilities within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement of each individual asset and liability taken as a whole. Measurement information for assets and liabilities that are measured at fair value on a recurring basis was as follows:
								Total Net Fair

	Total	$	14,310	$	-5,635	$	—	$	8,675
	The Company classifies assets and liabilities within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement of each individual asset and liability taken as a whole.
	There were no movements between Levels 1 and 2 during the three months ended March 31, 2014. The Company has not owned any Level 3 assets or liabilities since 2012.
	Additional Fair Value Disclosures — The Company has 7,250 outstanding shares of Series A Cumulative Redeemable Preferred Stock (“Series A Preferred Stock”) (see Note 8 — Redeemable Preferred Stock and Warrants) at March 31, 2014.  The obligation to redeem the preferred shares is reflected as debt (“mandatorily redeemable preferred stock”) and temporary equity (“Series A Cumulative Redeemable Preferred Stock”) in the condensed balance sheet (see Note 8 — Redeemable Preferred Stock and Warrants).  The fair value and the carrying value of these securities at December 31, 2013, were $30.9 million and $23.8 million, respectively, for the portion reflected as temporary equity and $71.9 million and $64.5 million, respectively, for the portion reflected in debt. The fair value and the carrying value of these securities at March 31, 2014, were $34.0 million and $26.1 million, respectively, for the portion reflected as temporary equity and $71.9 million and $64.9 million, respectively, for the portion reflected in debt. The fair value was determined by discounting the cash flows over the remaining life of the securities utilizing a LIBOR interest rate and a risk premium of approximately 12.9% and 13.2% at December 31, 2013, and March 31, 2014, respectively, which was based on companies with similar leverage ratios to PostRock. The Company has classified the valuation of these securities under Level 2 of the fair value hierarchy.
	The Company’s long-term debt consists entirely of floating-rate facilities. The carrying amount of floating-rate debt approximates fair value because the interest rates on such debt are generally set for periods of six months or shorter.

	Note 5 — Investment
	The Company elected the fair value option to account for its interest in CEP at inception. The fair value option was chosen as the Company determined that the market price of CEP’s publicly traded interests provided a more accurate fair value measure of the Company’s investment in CEP. The Company has not elected the fair value option for any of its other assets and liabilities. Although the Company no longer has the ability to exercise significant influence over CEP, it will continue to use the fair value option to account for such investment as that election is irrevocable. See further discussion below on the sale of CEP units.
	The following table presents the mark-to-market gains on our investment (recorded as a component of other income in the condensed consolidated statements of operations), our investment in CEP at gross fair value, and the valuation allowance on CEP investment, which includes certain proceeds received from the settlement agreement as described below (presented net in the consolidated balance sheets):

	On March 31, 2014, PostRock Energy Corporation and its wholly owned subsidiary, Constellation Energy Partners Management, LLC (“CEPM”), entered into a settlement agreement, fully resolving all claims associated with the lawsuit filed August 30, 2013 against CEP, CEP’s Chief Executive Officer, members of CEP’s Board of Managers, Sanchez Oil & Gas Corporation and Sanchez Energy Partners I, LP (“SEPI”).
	Under the settlement agreement, CEPM is to recover a target amount of $21.6 million (the “Target Amount”).  In the initial phase of the settlement, CEPM transferred 484,505 Class A units of CEP, representing 100% of the Class A units it owned, to SEPI, and received the sum of $817,767 from SEPI and an initial payment in the sum of $6,516,103 from CEP.  The $6.5 million was recorded as a valuation allowance related to the CEP investment in accordance with the principles of cost recovery method. When the value of our net investment reaches zero we will start realizing gains/losses in net income.  In addition, CEPM transferred 414,938 CEP Class B units to SEPI in exchange for $1 million from SEPI. After our mark to market adjustment for the B units, a loss of $78,839 was recorded in the investment valuation allowance; however, as mentioned earlier, no realized gain/loss will be recorded until the value of our investment reaches zero.  As of April 1, 2014, CEPM owned 5,503,956 Class B units, which it intends to dispose of subject to minimum price, volume and other limitations set forth in the settlement agreement. The Class B units may be sold in open market sales and underwritten offerings permitted by and subject to the terms of the settlement agreement.  In certain circumstances, SEPI may require CEPM to sell up to one-half of the subject units to third parties identified by SEPI.
	If, following application of (i) the amounts received in the initial phase as noted above and (ii) proceeds from the sale of all of CEPM’s Class B units, the Target Amount has not been met, SEPI will pay CEPM the difference, up to a maximum of $5 million.  On the other hand, if the Target Amount has been exceeded, CEPM will pay SEPI 50% of the surplus, up to a maximum payment to SEPI of $5 million.
	The settlement agreement provides that until CEPM’s ownership of Class B units has been reduced to less than one million units, CEPM has the right to appoint one observer to the CEP board of managers. The settlement agreement also contains certain restrictions concerning CEPM’s voting on issues brought to a unit-holder vote and participating in proxy solicitations or contests.

	Note 8 — Redeemable Preferred Stock and Warrants
	Prior to December 31, 2014, the Company may accrue dividends on its Series A Preferred Stock rather than paying them in cash. Whenever dividends are accrued on a quarterly dividend payment date, the liquidation preference of the Series A Preferred Stock is increased by the amount of the accrued dividends and additional warrants to purchase shares of PostRock common stock are issued. The Company records the increase in liquidation preference and the issuance of additional warrants by allocating their relative fair values to the amount of accrued dividends. The allocation results in an increase to the Company’s temporary equity related to the Series A Preferred Stock and an increase to additional paid in capital related to the additional warrants issued. The increase to additional paid in capital related to additional warrants issued for dividends paid-in-kind was $1.2 million during the three months ended March 31, 2014.

Profit Sharing And Deferred Compensation Plan	'
	Note 11 — Profit sharing and deferred compensation plans
	401K plan — Substantially all of the Company’s employees are eligible to participate in a profit sharing plan under Section 401(k) of the Internal Revenue Code (the “401K plan”). Prior to 2013, employer matching contributions to the 401K plan were made in cash. Beginning in the second quarter of 2013, employer matching contributions to the 401K plan may be made in Company common stock. In general, the Company issues common stock to fund its matching contributions although, from time to time, purchases of common stock on the open market by the 401K plan trust may occur if funds are available as a result of forfeitures.  During the three months ended March 31, 2014,  106,131 shares of common stock were contributed to the 401K plan, of which 105,884 shares were issued by the Company, and the remaining 247 shares were funded with forfeited shares already in the plan.
	The following table presents the expense incurred by the Company related to the 401K plan which is reflected in the condensed consolidated statements of operations as a component of general and administrative expense:
		Three Months Ended March 31,

	401(k) profit sharing plan cost	$	199	$	149
	Deferred compensation plan — Effective January 1, 2013, the Company established a deferred compensation plan that permits selected employees and members of its board to defer part or all of their eligible compensation. The Company issues common stock into a rabbi trust created to hold the assets associated with the plan. A participant’s deferred compensation is credited with earnings, gains and losses based on the Company’s common stock, the only investment option currently available under the plan. The Company may also make discretionary employer credits in an amount it determines each plan year. Distributions to participants will be made in shares of the Company’s common stock. Company shares held in the rabbi trust are recorded as treasury stock in the condensed consolidated balance sheets. Changes in the fair value of the deferred compensation obligation, currently recorded as a component of additional paid-in-capital, are not recognized.
	The following table presents the number of shares and the related fair values of common stock contributed by the Company to the deferred compensation plan during the three months ended March 31, 2013 and 2014. The fair value of common stock is based on the market price of the stock on the preceding day that the stock is transferred and thus deemed to be a Level 1 measurement under the fair value hierarchy.
