Accounting Policies [Abstract]
Accounting Policies And Disclosures	CHAPTER 11 PROCEEDINGS AND ACCOUNTING POLICIES Chapter 11 Proceedings On March 17, 2015, the Company and our subsidiaries Barnett Shale Operating LLC, Cowtown Drilling, Inc., Cowtown Gas Processing L.P., Cowtown Pipeline Funding, Inc., Cowtown Pipeline L.P., Cowtown Pipeline Management, Inc., Makarios Resources International Holdings LLC, Makarios Resources International Inc., QPP Holdings LLC, QPP Parent LLC, Quicksilver Production Partners GP LLC, Quicksilver Production Partners LP, and Silver Stream Pipeline Company LLC each filed a voluntary petition under Chapter 11 in the Bankruptcy Court to restructure our obligations and capital structure. The Chapter 11 cases are being jointly administered for procedural purposes only by the Bankruptcy Court under the caption In re Quicksilver Resources Inc., et. al. , Case No. 15-10585 (LSS) (Jointly Administered). The U.S. Debtors are currently operating our business as debtors in possession in accordance with the applicable provisions of the Bankruptcy Code. Since the Chapter 11 filings, the Bankruptcy Court has entered the orders necessary to enable the U.S. Debtors to conduct normal business activities, including orders to, among other things and subject to applicable caps for pre-petition items, pay employee wages and benefits, pay certain lienholders and critical vendors, and forward funds belonging to third parties, including royalty holders and partners, as well as the approval of the U.S. Debtors’ use of their secured lenders’ cash collateral and collateral, and the provision of adequate protection related thereto. While the U.S. Debtors are subject to Chapter 11, all transactions outside the ordinary course of their business will require the prior approval of the Bankruptcy Court. On March 16 and June 15, 2015, we, along with QRCI, entered into the Forbearance Agreements with the administrative agents and certain of the lenders under the Combined Credit Agreements. As a result of the Chapter 11 filing, the obligations under the Combined Credit Agreements were automatically accelerated. However, pursuant to the Forbearance Agreements, the administrative agents and the lenders agreed to, among other things, (i) forbear from exercising their rights and remedies in connection with specified defaults under the Amended and Restated Canadian Credit Facility related to our Chapter 11 filing until the earlier of September 16, 2015 or certain other events specified in the Forbearance Agreements, including, among other things, the commencement by QRCI or certain specified Canadian subsidiary guarantors of insolvency proceedings and (ii) waive compliance with certain specified terms and conditions relating to the renewal of outstanding evergreen letters of credit under the Combined Credit Agreements, among other things. Appointment of Creditors Committee. On March 25, 2015, the United States Trustee for Delaware appointed the Creditors Committee. The Creditors Committee and its legal representatives have a right to be heard on all matters that come before the Bankruptcy Court with respect to the U.S. Debtors. There can be no assurance that the Creditors Committee will support the U.S. Debtors’ positions on matters presented to the Bankruptcy Court, including any plan of reorganization. Disagreements between the U.S. Debtors and the Creditors Committee could protract the Chapter 11 proceedings, negatively impact the U.S. Debtors’ ability to operate, and delay the U.S. Debtors’ emergence from the Chapter 11 proceedings. The U.S. Debtors’ Exclusivity Periods. On July 7, 2015, the Bankruptcy Court entered an order extending the U.S Debtors’ (i) Exclusive Filing Period through and including October 13, 2015 and (ii) Exclusive Solicitation Period through and including December 14, 2015. The U.S. Debtors requested and were granted a 90-day extension of the Exclusive Periods to afford them the opportunity to complete the critical tasks necessary to develop and negotiate a chapter 11 plan with their creditors. Rejection of Executory Contracts. Subject to certain exceptions, under the Bankruptcy Code, the U.S. Debtors may assume, assign, or reject certain executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions. The rejection of an executory contract or unexpired lease is generally treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the U.S. Debtors of performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach. Counterparties to such rejected contracts or leases may assert claims against the applicable U.S. Debtor's estate for such damages. The assumption of an executory contract or unexpired lease generally requires the U.S. Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance. Accordingly, any description of an executory contract or unexpired lease with the U.S. Debtors in this Quarterly Report, including where applicable a quantification of our obligations under any such executory contract or unexpired lease with the U.S. Debtors, is qualified by any overriding rejection rights we have under the Bankruptcy Code. Further, nothing herein is or shall be deemed an admission with respect to any claim amounts or calculations arising from the rejection of any executory contract or unexpired lease and the U.S. Debtors expressly preserve all of their rights with respect thereto. The U.S. Debtors’ financial statements include amounts classified as Liabilities Subject to Compromise that the U.S. Debtors believe the Bankruptcy Court will allow as claim amounts resulting from the U.S. Debtors’ rejection of various executory contracts and unexpired leases. Additional amounts may be included in Liabilities Subject to Compromise in future periods if additional executory contracts and unexpired leases are rejected. Conversely, the U.S. Debtors expect that the assumption of certain executory contracts and unexpired leases may convert certain liabilities shown in future financial statements as subject to compromise to post-petition liabilities. Due to the uncertain nature of many of the potential claims, the magnitude of such claims is not reasonably estimable at this time. Such claims may be material (see “Liabilities Subject to Compromise” below). Magnitude of Potential Claims. On June 9, 2015, the U.S. Debtors filed with the Bankruptcy Court Schedules and Statements setting forth, among other things, the assets and liabilities of the U.S. Debtors, subject to the assumptions filed in connection therewith. The Schedules and Statements may be subject to further amendment or modification. Certain holders of pre-petition claims were required to file proofs of claim by the Bar Date. As of July 31, 2015, approximately 489 claims totaling about $6.4 billion had been filed with the Bankruptcy Court against the U.S. Debtors, and we expect new and amended claims to be filed in the future, including claims amended to assign values to claims originally filed with no designated value. Through the claims resolution process we have identified, and we expect to continue to identify many claims that we believe should be disallowed by the Bankruptcy Court because they are duplicative, have been later amended or superseded, are without merit, are overstated or for other reasons. We will file objections with the Bankruptcy Court as necessary for claims we believe should be disallowed. Claims we believe are allowable are included in Liabilities Subject to Compromise. Through the claims resolution process, differences in amounts scheduled by the U.S. Debtors and claims filed by creditors will be investigated and resolved, including through the filing of objections with the Bankruptcy Court where appropriate. In light of the number and amount of claims filed, the claims resolution process may take considerable time to complete, and we expect that it will continue after our emergence from bankruptcy. Accordingly, the ultimate number and amount of allowed claims is not presently known, nor can the ultimate recovery with respect to allowed claims be presently ascertained. Costs of Reorganization. The U.S. Debtors have incurred and will continue to incur significant costs associated with the reorganization. The amount of these costs, which are being expensed as incurred, are expected to significantly affect our results of operations. For additional information, see “Reorganization Items, net” below. Effect of Filing on Creditors and Stockholders. Under the priority scheme established by the Bankruptcy Code, unless creditors agree otherwise, pre-petition liabilities and post-petition liabilities must be satisfied in full before the holders of our existing common stock are entitled to receive any distribution or retain any property under a plan of reorganization. The ultimate recovery to creditors and/or stockholders, if any, will not be determined until confirmation and implementation of a plan or plans of reorganization. No assurance can be given as to what values, if any, will be ascribed in the Chapter 11 proceedings to each of these constituencies or what types or amounts of distributions, if any, they would receive. A plan of reorganization could result in holders of U.S. Debtors’ liabilities and/or securities, including our common stock, receiving no distribution on account of their interests and cancellation of their holdings. We believe that it is highly likely that the shares of our existing common stock will be canceled in the Chapter 11 proceedings and will be entitled to a limited recovery, if any. As discussed below, if certain requirements of the Bankruptcy Code are met, a plan of reorganization can be confirmed notwithstanding its rejection by the holders of our common stock and notwithstanding the fact that such holders do not receive or retain any property on account of their equity interests under the plan. Because of such possibilities, the value of our securities, including our common stock, is highly speculative. We urge that appropriate caution be exercised with respect to existing and future investments in any of the securities of the U.S. Debtors. Subject to certain specific exceptions under the Bankruptcy Code, the Chapter 11 filings automatically enjoined, or stayed, the continuation of any judicial or administrative proceedings or other actions against the U.S. Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date. As a result, for example, most creditor actions to obtain possession of property from the U.S. Debtors, or to create, perfect or enforce any lien against the property of the U.S. Debtors, or to collect on or otherwise exercise rights or remedies with respect to a pre-petition claim are enjoined unless and until the Bankruptcy Court lifts the automatic stay. Notice and Hearing Procedures for Trading in Claims and Equity Securities. The Bankruptcy Court issued a final order pursuant to Sections 105(a), 362(a)(3) and 541 of the Bankruptcy Code to enable the U.S. Debtors to avoid limitations on the use of their tax net operating loss carryforwards and certain other tax attributes by imposing certain notice procedures and transfer restrictions on the trading of our equity securities. In general, the order applies to any person or entity that, directly or indirectly, beneficially owns (or would beneficially own as a result of a proposed transfer) at least 4.75% of our outstanding equity securities. Substantial Equityholders are required to file with the Bankruptcy Court and serve us with notice of such status. In addition, the order provides that a person or entity that would become a Substantial Equityholder by reason of a proposed acquisition of our equity securities is also required to comply with the notice and service provisions before effecting that transaction. The order gives the U.S. Debtors the right to seek an injunction from the Bankruptcy Court to prevent certain acquisitions or sales of our common stock if the acquisition or sale would pose a material risk of adversely affecting our ability to utilize such tax attributes. Under the order, prior to any proposed acquisition of equity securities that would result in an increase in the amount of our equity securities owned by a Substantial Equityholder, or that would result in a person or entity becoming a Substantial Equityholder, such person, entity or Substantial Equityholder is required to file with the Bankruptcy Court, and serve on the Company, a Notice of Intent to Purchase, Acquire or Otherwise Accumulate an Equity Security. In addition, prior to effecting any disposition of our equity securities that would result in a decrease in the amount of our equity securities beneficially owned by a Substantial Equityholder, such Substantial Equityholder is required to file with the Bankruptcy Court, and serve on the Company, a Notice of Intent to Sell, Trade or Otherwise Transfer Equity Securities. Any purchase, sale or other transfer of our equity securities in violation of the restrictions of the order would be null and void ab initio as an act in violation of such order and would therefore confer no rights on a proposed transferee. Process for Plan of Reorganization. In order to successfully exit bankruptcy, the U.S. Debtors will need to propose, and obtain confirmation by the Bankruptcy Court of, a plan (or plans) of reorganization that satisfies the requirements of the Bankruptcy Code. A plan of reorganization would, among other things, resolve the U.S. Debtors’ pre-petition obligations, set forth the revised capital structure of the newly reorganized entity and provide for corporate governance subsequent to exit from bankruptcy. The U.S. Debtors have the exclusive right for 120 days after the Petition Date to file a plan of reorganization and have been granted a 90 day extension to the Exclusive Periods. If we file a plan of reorganization, the U.S. Debtors have 60 additional days to obtain necessary acceptances of our plan. The periods may be further extended by the Bankruptcy Court for cause. If the U.S. Debtors’ Exclusive Filing Period lapses, any party in interest may file a plan of reorganization for any of the U.S. Debtors. As discussed above, the Bankruptcy Court has extended the U.S. Debtors’ Exclusive Filing Period through October 13, 2015 and the Exclusive Solicitation Period through December 14, 2015. In addition to being voted on by holders of impaired claims and equity interests, a plan of reorganization must satisfy certain requirements of the Bankruptcy Code and must be approved, or confirmed, by the Bankruptcy Court in order to become effective. A plan of reorganization would be accepted by holders of claims against and equity interests in the U.S. Debtors if (i) at least one-half in number and two-thirds in dollar amount of claims actually voting in each class of claims impaired by the plan have voted to accept the plan and (ii) at least two-thirds in amount of equity interests actually voting in each class of equity interests impaired by the plan has voted to accept the plan. A class of claims or equity interests that does not receive or retain any property under the plan on account of such claims or interests is deemed to have voted to reject the plan. Under certain circumstances set forth in Section 1129(b) of the Bankruptcy Code, the Bankruptcy Court may confirm a plan even if such plan has not been accepted by all impaired classes of claims and equity interests. The precise requirements and evidentiary showing for confirming a plan notwithstanding its rejection by one or more impaired classes of claims or equity interests depends upon a number of factors, including the status and seniority of the claims or equity interests in the rejecting class (i.e., secured claims or unsecured claims, subordinated or senior claims, preferred or common stock). Generally, with respect to common stock interests, a plan may be “crammed down” even if the shareowners receive no recovery if the proponent of the plan demonstrates that (1) no class junior to the common stock is receiving or retaining property under the plan and (2) no class of claims or interests senior to the common stock is being paid more than in full. The timing of filing a plan of reorganization by the U.S. Debtors will depend on the timing and outcome of numerous other ongoing matters in the Chapter 11 proceedings. Although the U.S. Debtors expect to file a plan of reorganization that provides for our emergence from bankruptcy as a going concern, there can be no assurance at this time that the U.S. Debtors will be able to successfully develop, confirm and consummate one or more plans of reorganization or other alternative restructuring transactions, including a sale of all or substantially all of the U.S. Debtors’ assets, that satisfies the conditions of the Bankruptcy Code and is confirmed by the Bankruptcy Court, or that any such plan will be implemented successfully. For the duration of our Chapter 11 proceedings, our operations and our ability to develop and execute our business plan are subject to the risks and uncertainties associated with the Chapter 11 process as described in our 2014 Annual Report on Form 10-K, Item 1A, “Risk Factors.” As a result of these risks and uncertainties, the number of our outstanding shares and our stockholders, assets, liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 proceedings, and the description of our operations, properties and capital plans included in this Quarterly Report may not accurately reflect our operations, properties and capital plans following the Chapter 11 process. Basis of Presentation The accompanying condensed consolidated interim financial statements have not been audited. In management’s opinion, the accompanying condensed consolidated interim financial statements contain all adjustments necessary to fairly present our financial position as of June 30, 2015 and our results of operations and cash flows for the periods presented. All such adjustments are of a normal recurring nature unless otherwise noted. The results for interim periods are not necessarily indicative of annual results. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of certain assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during each reporting period. We believe our estimates and assumptions are reasonable; however, such estimates and assumptions are subject to a number of risks and uncertainties, which may cause actual results to differ materially from management’s estimates. Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these financial statements should be read in conjunction with our consolidated financial statements and notes thereto included in our 2014 Annual Report on Form 10-K. As a result of sustained losses and our Chapter 11 proceedings, the realization of assets and satisfaction of liabilities, without substantial adjustments and/or changes in ownership, are subject to uncertainty. Given the uncertainty surrounding our Chapter 11 proceedings, there is substantial doubt about our ability to continue as a going concern. The accompanying condensed consolidated interim financial statements do not purport to reflect or provide for the consequences of our Chapter 11 proceedings, other than as set forth under Liabilities Subject to Compromise and Reorganization Items, net on the accompanying condensed consolidated interim financial statements. In particular, the financial statements do not purport to show (i) as to assets, their realizable value on a liquidation basis or their availability to satisfy liabilities; (ii) as to pre-petition liabilities, the amounts that may be allowed for claims or contingencies, or the status and priority thereof; (iii) as to stockholders’ equity accounts, the effect of any changes that may be made in our capitalization; or (iv) as to operations, the effect of any changes that may be made to our business. In accordance with GAAP, we have applied ASC 852 “Reorganizations,” in preparing our condensed consolidated interim financial statements. ASC 852 requires that the financial statements, for periods subsequent to the Chapter 11 filing, distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses, realized gains and losses and provisions for losses that are realized or incurred in the bankruptcy proceedings are recorded in Reorganization Items, net in the accompanying condensed consolidated statements of income (loss) and comprehensive income (loss). In addition, pre-petition obligations that may be impacted by the bankruptcy reorganization process have been classified on our condensed consolidated balance sheets at June 30, 2015 in Liabilities Subject to Compromise. These liabilities are reported at the amounts expected to be allowed by the Bankruptcy Court, even if they may be settled for lesser amounts. While operating as debtors in possession under Chapter 11 of the Bankruptcy Code, the U.S. Debtors may sell or otherwise dispose of or liquidate assets or settle liabilities in amounts other than those reflected in our condensed consolidated interim financial statements, subject to the approval of the Bankruptcy Court or otherwise as permitted in the ordinary course of business. Further, a plan of reorganization could materially change the amounts and classifications in our historical condensed consolidated interim financial statements. Liabilities Subject to Compromise The following table summarizes the components of liabilities subject to compromise included on our Condensed Consolidated Balance Sheet as of June 30, 2015 : June 30, 2015 (in thousands) Accounts payable $ 1,016 Accrued liabilities 116,984 Debt 1,781,156 Liabilities subject to compromise $ 1,899,156 Liabilities Subject to Compromise refers to pre-petition obligations that may be impacted by the Chapter 11 reorganization process. The amounts represent our current estimate of known or potential obligations to be resolved in connection with our Chapter 11 proceedings. Accrued liabilities primarily includes previously accrued and unpaid interest that is associated with the debt that we believe may be impacted by the bankruptcy reorganization process. Differences between liabilities we have estimated and the claims filed, or to be filed, will be investigated and resolved in connection with the claims resolution process. We will continue to evaluate these liabilities throughout the Chapter 11 process and adjust amounts as necessary. Such adjustments may be material. Reorganization Items, net The following table summarizes the components included in Reorganization Items, net in our condensed consolidated statements of income (loss) and comprehensive income (loss) for the three and six months ended June 30, 2015 : For the Three Months Ended June 30, 2015 For the Six Months Ended June 30, 2015 (in thousands) Professional fees $ 12,502 $ 14,543 Deferred financing costs and unamortized discounts — 59,983 Deferred interest rate swap gains — (2,314 ) Terminated contracts 67,538 68,473 Reorganization items, net $ 80,040 $ 140,685 Professional fees included in Reorganization Items, net are for post-petition expenses. Deferred financing costs and unamortized discounts are included for the Second Lien Term Loan, Second Lien Notes, Senior Notes due 2019, Senior Notes due 2021 and Senior Subordinated Notes as we believe these debt instruments may be impacted by the bankruptcy reorganization process. Terminated contracts represent the estimated claims related to five GPT and one professional fee contracts that run through 2019 and were not previously included on the balance sheet as the liability was contingent or an executory contract included in commitments and contingencies. The amount is derived by using the undiscounted contractual rates multiplied by the remaining contractual volumes and will be adjusted through the claims reconciliation process as necessary. Recently Issued Accounting Standards In February 2015, the FASB issued accounting guidance, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” requiring reporting entities to evaluate whether they should consolidate certain legal entities. The standard is effective for us in the first quarter of 2016 with early adoption permitted. We are currently evaluating the new guidance and have not determined the impact this standard may have on our financial statements. In April 2015, the FASB issued accounting guidance, “Interest - Imputation of Interest” that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This update is effective for us in the first quarter of 2016. We are currently evaluating the timing of adoption and the impact that the adoption will have on our consolidated financial statements. In July 2015, the FASB voted to extend by one year the effective date to adopt the accounting guidance, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue that it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Reporting entities may elect to adopt the guidance at the original effective date or may delay one year. We intend to delay the adoption of this guidance until the first quarter of 2018. We have not yet selected a transition method and we are currently evaluating the effect, if any, that the updated standard will have on our consolidated financial statements and related disclosures. In July 2015, the FASB issued accounting guidance, “Simplifying the Measurement of Inventory,” that requires inventory to be measured at the lower of cost and net realizable value and options that currently exist for market value to be eliminated. The guidance defines net realizable value as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The guidance is effective on a prospective basis for reporting periods beginning after December 15, 2016 and interim periods within those fiscal years with early adoption permitted. We are evaluating the impact that the adoption will have on our consolidated financial statements. No other pronouncements materially affecting our financial statements have been issued since the filing of our 2014 Annual Report on Form 10-K.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	DIVESTITURES In May 2014, we completed the sale of our Niobrara Asset to Southwestern Energy Company. The purchase price was subject to customary purchase price adjustments, which resulted in Southwestern paying us $95.6 million , including a final adjustment of $2.1 million , which we received in the third quarter of 2014. We determined that the Southwestern Transaction did not represent a significant disposal of reserves under GAAP, therefore we reduced the balance of U.S. oil and gas properties by the amount of these proceeds and we did not recognize a gain or loss. Note 3 to the consolidated financial statements in our 2014 Annual Report on Form 10-K contains additional information on other divestitures.

Credit Risk Derivatives, at Fair Value, Net [Abstract]
Derivatives And Fair Value Measurements	DERIVATIVES AND FAIR VALUE MEASUREMENTS The following table categorizes our commodity derivative instruments based upon the level of the inputs used in estimating the fair value: Asset Derivatives Liability Derivatives June 30, 2015 December 31, 2014 June 30, 2015 December 31, 2014 (in thousands) (in thousands) Level 2 derivative instruments $ 4,572 $ 104,608 $ — $ — Level 3 derivative instruments — 44,959 — — Total $ 4,572 $ 149,567 $ — $ — The fair value of “Level 2” derivative instruments included in these disclosures was estimated using inputs quoted in active markets for the periods covered by the derivatives. The fair value of derivative instruments designated as “Level 3” at December 31, 2014, was estimated using prices quoted in markets where there is insufficient market activity for consideration as “Level 2” instruments. At December 31, 2014, only our natural gas derivatives with an original tenure of 10 years utilized “Level 3” inputs, primarily due to comparatively less market data available for the later portion of their term compared with our other shorter term derivatives. The fair value of both the “Level 2” and the “Level 3” assets and liabilities are determined using a discounted cash flow model using the terms of the derivative instrument, market prices for the periods covered by the derivatives, and the credit adjusted risk-free interest rates. The “Level 3” unobservable input at December 31, 2014 was the market prices for natural gas for the period from 2019 to 2021, as there is not an active market for that period of time. These unobservable inputs included within the fair value calculation range at December 31, 2014 from $2.88 to $4.60 and are based upon prices quoted in active markets for the period of time available. A decrease of these unobservable inputs would increase the fair value, while an increase would decrease the fair value. The following table identifies the changes in “Level 3” net asset derivative fair values for the periods indicated: For the Three Months Ended 2015 2014 (in thousands) Balance at beginning of period $ — $ 7,201 Total gains (losses) for the period: Unrealized gain (loss) on derivatives — (13,434 ) Settlements in net derivative gains (losses) — 700 Balance at end of period $ — $ (5,533 ) Total gains (losses) included in net derivative gains (losses) attributable to the change in unrealized gains (losses) related to assets still held at the reporting date $ — $ (11,385 ) For the Six Months Ended 2015 2014 (in thousands) Balance at beginning of period $ 44,959 $ 23,485 Total gains (losses) for the period: Unrealized gain (loss) on derivatives (109,240 ) (31,317 ) Settlements in net derivative gains (losses) 64,281 2,299 Balance at end of period $ — $ (5,533 ) Total gains (losses) included in net derivative gains (losses) attributable to the change in unrealized gains (losses) related to assets still held at the reporting date $ — $ (26,961 ) Commodity Price Derivatives Between January and March 2015, substantially all of our derivatives were restructured or terminated either by us or the counterparties to such derivatives in anticipation or as a result of our Chapter 11 filings. These restructured and terminated derivatives reduced our daily production volume of natural gas economically hedged to 20 MMcfd in 2015 and we no longer have any derivatives beyond 2015. The cash proceeds from derivatives terminated in 2015 were $135.7 million . Effective December 31, 2012, we discontinued the use of hedge accounting. Changes in value subsequent to this date are recognized in net derivative gains (losses) in the period in which they occur. The net deferred hedge gain that was included in AOCI as of December 31, 2012 is being released into revenue from natural gas, NGL and oil production over the original term of the hedging relationship (through 2021). Gains from the effective portion of derivative assets and liabilities held in AOCI expected to be reclassified into earnings during the following twelve months will result in production revenue of $15.9 million net of income taxes. Interest Rate Derivatives In 2010, we executed early settlements of our interest rate swaps that were designated as fair value hedges. Upon the early settlements, we recorded the resulting gain as a fair value adjustment to our debt and began to recognize the deferred gain as a reduction of interest expense over the lives of the respective notes. During the six months ended June 30, 2015 and 2014 , we recognized $0.5 million and $1.0 million , respectively, of those deferred gains as a reduction of interest expense. As a result of the Chapter 11 proceedings, the remainder of the deferred gains related to these interest rate swaps were included in Reorganization Items, net. Fair Value Disclosures The estimated fair value of our derivative instruments at June 30, 2015 and December 31, 2014 were as follows: Asset Derivatives Liability Derivatives June 30, 2015 December 31, 2014 June 30, 2015 December 31, 2014 (in thousands) (in thousands) Derivatives not designated as hedges: Commodity contracts reported in: Current derivative assets $ 4,572 $ 120,176 $ — $ — Noncurrent derivative assets — 81,187 — 51,796 Total derivatives not designated as hedges $ 4,572 $ 201,363 $ — $ 51,796 Derivative assets and liabilities shown in the table above are presented as gross assets and liabilities, without regard to master netting arrangements, which are considered in the presentation of derivative assets and liabilities in the accompanying condensed consolidated balance sheets. The change in carrying value of our commodity price derivatives since December 31, 2014 principally resulted from the termination of the majority of our derivatives. Financial instruments not carried at fair value Carrying values and fair values of financial instruments that are not carried at fair value in the consolidated balance sheets as of June 30, 2015 and December 31, 2014 are included in Note 5.

We computed the June 30, 2015 ceiling amounts for our Canadian oil and gas properties using AECO prices of $2.90 per MMBtu of natural gas, calculated as the unweighted average of the preceding 12-month first-day-of-the-month prices. The AECO natural gas prices used to compute the ceiling amount at June 30, 2015 was 31% lower than the comparable price used at December 31, 2014. Notes 2 and 7 to the consolidated financial statements in our 2014 Annual Report on Form 10-K contain additional information regarding our property, plant and equipment and our quarterly ceiling test analysis.

Long-term Debt, Other Disclosures [Abstract]
Long-Term Debt	DEBT Debt consisted of the following: June 30, 2015 December 31, 2014 (in thousands) Combined Credit Agreements $ 164,288 $ 274,514 Second Lien Term Loan, net of unamortized discount (1) — 610,242 Second Lien Notes due 2019, net of unamortized discount (1) — 195,277 Senior notes due 2019, net of unamortized discount (1) — 293,919 Senior notes due 2021, net of unamortized discount (1) — 310,590 Senior subordinated notes due 2016 (1) — 350,000 Total debt 164,288 2,034,542 Unamortized deferred gain-terminated interest rate swaps — 2,763 Current portion of long-term debt (2) (164,288 ) (2,037,305 ) Long-term debt (2) $ — $ — (1) Classified as Liability Subject to Compromise as of June 30, 2015 (2) As a result of our Chapter 11 filings, we have classified all debt as current at June 30, 2015 On March 16 and June 15, 2015, we, along with QRCI, entered into the Forbearance Agreements with the administrative agents and certain of the lenders under the Combined Credit Agreements. As a result of the Chapter 11 filing, the obligations under the Combined Credit Agreements were automatically accelerated. However, pursuant to the Forbearance Agreements, the administrative agents and certain of the lenders agreed to, among other things, (i) forbear from exercising their rights and remedies in connection with specified defaults under the Amended and Restated Canadian Credit Facility related to our Chapter 11 filing until the earlier of September 16, 2015 or certain other events specified in the Forbearance Agreements, including, among other things, the commencement by QRCI or certain specified Canadian subsidiary guarantors of insolvency proceedings and (ii) waive compliance with certain specified terms and conditions relating to the renewal of outstanding evergreen letters of credit under the Combined Credit Agreements, among other things. In March 2015, a third-party service provider drew down the full face amount of a C$33 million letter of credit in connection with the termination of a Canadian gathering and processing contract. See additional discussion in Note 7. In April and May 2015, other third-party service providers in the U.S. drew down $2.1 million of outstanding letters of credit. As of June 30, 2015, $164.3 million in loans ( $81.8 million and $82.5 million in the U.S. and Canada, respectively) and $9.8 million ( $7.7 million and $2.1 million in the U.S. and Canada, respectively) in letters of credit were outstanding under our Combined Credit Agreements. Our Chapter 11 filings constituted an event of default under the Combined Credit Agreements and all borrowings and other fees under the Combined Credit Agreements became immediately due and payable. As a result, we no longer have any liquidity available to us under the Combined Credit Agreements. The ability of the lenders under the Combined Credit Agreements to seek remedies to enforce their rights under the agreements against the U.S. Debtors was automatically stayed as a result of the Chapter 11 filings, and the lenders’ rights of enforcement against the U.S. Debtors are subject to the applicable provisions of the Bankruptcy Code. Amounts outstanding under the Combined Credit Agreements have not been included in Liabilities Subject to Compromise because we believe the secured debt will not be impacted by the bankruptcy reorganization process. We continue to accrue and pay interest on the Combined Credit Agreements in accordance with the Forbearance Agreement and the Bankruptcy Court’s cash collateral order. Beginning on March 17, 2015, as part of the Forbearance Agreement, we agreed to pay interest monthly for the Amended and Restated U.S. Credit Facility at a specified rate of ABR plus the applicable margin and for the Amended and Restated Canadian Credit Facility at a specified rate of Canadian prime plus the default rate plus the applicable margin for Canadian dollar denominated borrowings, and U.S. prime plus the default rate plus the applicable margin, for U.S. dollar denominated borrowings. Subsequent to the Forbearance Agreement, we agreed in connection with the adequate protection package, which allowed for the use of cash collateral and collateral, to fix the applicable margin for loans under the Amended and Restated U.S. Credit Facility to 2.5% . We also agreed to set the applicable margin for loans under the Amended and Restated Canadian Credit Facility to 2.75% . At June 30, 2015, the weighted average interest rate for amounts outstanding under the Combined Credit Agreement was 6.72% . In April 2015, we repaid $88.0 million ( $46.5 million and $41.5 million in the U.S. and Canada, respectively) and in June 2015 we repaid an additional $11.1 million in the U.S., of outstanding amounts under our Combined Credit Agreements with proceeds from terminated derivative positions. Our Chapter 11 filings also constituted an event of default under the Second Lien Term Loan, the Second Lien Notes, the Senior Notes due 2019, the Senior Notes due 2021, and the Senior Subordinated Notes. All principal, interest and other amounts under each of these debt instruments became immediately due and payable. The ability of the lenders and noteholders to seek remedies to enforce their rights under the applicable debt instruments was automatically stayed as a result of the Chapter 11 filings, and the lenders’ and noteholders’ rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. Amounts outstanding under the Second Lien Term Loan, Second Lien Notes, Senior Notes due 2019, Senior Notes due 2021 and Senior Subordinated Notes have been reclassified as Liabilities Subject to Compromise. We discontinued the accrual of interest on the Second Lien Term Loan, Second Lien Notes, Senior Notes due 2019, Senior Notes due 2021 and Senior Subordinated Notes from and after the Petition Date. However, we are making adequate protection payments to the lenders under the Second Lien Term Loan and the holders of the Second Lien Notes, in each case in an amount equal to all accrued and unpaid post-petition interest (at a rate of 7.00% as of June 30, 2015), fees and costs due and payable on a monthly basis under the Second Lien Term Loan and the indenture for the Second Lien Notes, respectively, in accordance with the Bankruptcy Court’s cash collateral order. As the Bankruptcy Court will ultimately determine the treatment of all amounts subject to compromise and our Second Lien Term Loan and Second Lien Notes may be impacted by the bankruptcy reorganization process, the adequate protection payments are treated as a principal payment rather than as interest expense. The Bankruptcy Court could recharacterize these payments as diminution in value claims or interest payments or find that additional amounts are due, which in each case could require us to expense these payments. As of June 30, 2015 we have made aggregate payments of $16.8 million under the Bankruptcy Court’s cash collateral order. Summary of All Outstanding Debt Except where otherwise noted, the following table summarizes certain significant aspects of our long-term debt outstanding immediately prior to the Chapter 11 filings. Upon the Chapter 11 filings, all principal, interest and other amounts under each of the debt instruments governing the long-term debt set forth in the table below was accelerated and became immediately due and payable. The information in the table below is presented without regard to the effect of the Chapter 11 filings, except where otherwise noted, and therefore does not take into account the acceleration of the listed debt instruments and other impacts of the Chapter 11 filings.

(with respect to the Amended and Restated U.S. Credit Facility, on a ratable basis with borrowings under the Amended and Restated Canadian Credit Facility) and the majority of Quicksilver's domestic proved oil and gas properties and related assets, (the “Domestic Pledged Property”). Borrowings under the Amended and Restated Canadian Credit Facility are guaranteed by Quicksilver and certain of its domestic subsidiaries and are secured by the Domestic Pledged Equity, the Domestic Pledged Property, 100% of the equity interests of QRCI ( 65% of which is on a ratable basis with the borrowings under the Amended and Restated U.S. Credit Facility) and any Canadian restricted subsidiaries, under the Amended and Restated Canadian Credit Facility, and 65% of the equity interests of Quicksilver Production Partners Operating Ltd. (which is on a ratable basis with the borrowings under the Amended and Restated U.S. Credit Facility) and the majority of QRCI's oil and gas properties and related assets. The other debt presented is based upon structural seniority and priority of payment. (2) The principal amount included in the table for the Combined Credit Agreements represents the global borrowing base immediately prior to the Chapter 11 filings. (3) Immediately prior to acceleration as a result of the Chapter 11 filings, the Combined Credit Agreements were required to be repaid 91 days prior to the maturity of the Senior Subordinated Notes, the Second Lien Term Loan or the Second Lien Notes due 2019, if on the applicable date any amount of such debt remained outstanding. Immediately prior to acceleration as a result of the Chapter 11 filings, the Second Lien Term Loan and Second Lien Notes due 2019 were required to be repaid (1) 91 days prior to the maturity of the 2019 Senior Notes if more than $100 million of the 2019 Senior Notes remained outstanding and (2) 91 days prior to the maturity of the Senior Subordinated Notes if on the applicable date the amount remaining outstanding was greater than $100 million . Immediately prior to acceleration as a result of the Chapter 11 filings, as then structured and assuming no changes in the amounts outstanding, amounts outstanding under the Combined Credit Agreements would have been due on October 2, 2015 and the Second Lien Term Loan and Second Lien Notes would have been due on January 1, 2016. (4) Represents the weighted average borrowing rate payable to lenders on our Combined Credit Agreement as of June 30, 2015. (5) Immediately prior to the Chapter 11 filings, amounts outstanding under the Amended and Restated U.S. Credit Facility bore interest, at our election, at (i) adjusted LIBOR (as defined in the Amended and Restated U.S. Credit Facility) plus an applicable margin between 2.75% and 3.75% , or (ii) ABR (as defined in the Amended and Restated U.S. Credit Facility), which is the greatest of (a) the prime rate announced by JPMorgan, (b) the federal funds rate plus 0.50% and (c) adjusted LIBOR for an interest period of one month plus 1.00% , plus, in each case under scenario (ii), an applicable margin between 1.75% and 2.75% . We also pay a per annum fee on the LC Exposure (as defined in the Amended and Restated U.S. Credit Facility) of all letters of credit issued under the Amended and Restated U.S. Credit Facility equal to the applicable margin with respect to Eurodollar loans, and a commitment fee on the unused availability under the Amended and Restated U.S. Credit Facility of 0.50% . (6) Immediately prior to the Chapter 11 filings, amounts outstanding under the Amended and Restated Canadian Credit Facility bore interest, at our election, at (i) the CDOR Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 2.75% and 3.75% , (ii) the Canadian Prime Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 1.75% and 2.75% , (iii) the U.S. Prime Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 1.75% and 2.75% or (iv) adjusted LIBOR (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 2.75% and 3.75% .

(7) The financial covenants and significant restrictive covenants were applicable to the Combined Credit Agreements immediately prior to the Chapter 11 filings and remain applicable to the Amended and Restated Canadian Credit Facility. However, pursuant to the Forbearance Agreements, the administrative agent and certain lenders agreed to, among other things, forbear from exercising their rights and remedies in connection with specified defaults under the Amended and Restated Canadian Credit Facility, including events of default related to our Chapter 11 filings or the failure to comply with the financial covenants, until the earlier of September 16, 2015 or certain other events specified in the Forbearance Agreements. The following table sets forth the minimum EBITDAX covenant for the Amended and Restated U.S. Credit Facility immediately prior to the Chapter 11 filings and for the Amended and Restated Canadian Credit Facility: Minimum EBITDAX Covenant (in millions) Nine months ending June 30, 2015 87.25 Twelve months ending September 30, 2015 120.5 Twelve months ending December 31, 2015 122.0 Immediately prior to the Chapter 11 filings, the minimum required interest coverage ratio for the Amended and Restated U.S. Credit Facility for the first and second quarters of 2016 was 1.50 and 2.00 , respectively. The minimum required interest coverage ratio for the Amended and Restated Canadian Credit Facility for the first and second quarters of 2016 is 1.50 and 2.00 , respectively. (8) Immediately prior to acceleration as a result of our Chapter 11 filings, our indentures required us to reinvest or repay senior debt with net cash proceeds from certain asset sales within one year. (9) The information presented in this table is qualified in all respects by reference to the full text of the covenants, provisions and related definitions contained in the documents governing the various components of our debt. (10) The estimated fair value is determined using market quotations based on recent trade activity for fixed rate obligations (“Level 2” inputs). Our Second Lien Term Loan and Second Lien Notes feature variable interest rates and we estimate their fair value by using market quotations based on recent trade activity (“Level 3” input). We consider our Combined Credit Agreements, which have a variable interest rate, to have a fair value equal to their carrying value (“Level 1” input).

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Note 12 to the consolidated financial statements in our 2014 Annual Report on Form 10-K contains additional information about our income taxes. At June 30, 2015 , our U.S. and Canadian valuation allowances are $419.1 million and $95.5 million , respectively, which reduce our net deferred tax assets to a zero value as we continue to believe that it is not more likely than not that we will realize the deferred tax assets primarily related to our cumulative net operating losses. Income tax recognized for the six months ended June 30, 2015 is a result of hedge gains previously deferred in AOCI being realized during the periods. In June 2015, the Alberta government passed regulation to increase the provincial tax rate by 2% with an effective date of July 2015. We have adjusted our rates based on this change during the quarter ended June 30, 2015.

Loss Contingency [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES QRCI did not pay an uneconomic Canadian gathering and processing commitment, which included significant unused firm capacity, due in late February 2015. In early March 2015, the third-party service provider issued a demand letter regarding the missed payment and suspended service resulting in our Horn River Asset production being shut-in. Further, a termination notice was issued by the third-party service provider effective March 19, 2015. We continue to explore alternatives to gather and process our Horn River Asset production; however, we may not be able to find economic alternatives in the near-term, or at all, and production may remain shut-in. In connection with this Canadian gathering and processing contract, we had previously issued a letter of credit in the amount of C$33 million . Upon termination, the third party drew down the full face amount of the letter of credit. We do not believe the third party was legally entitled to draw down the entire amount of the letter of credit and we have reserved all of our rights, entitlements and remedies in that regard. The C$33 million draw is shown as a reduction to amounts outstanding under the contract for services provided prior to the termination and the remaining $21.5 million is recognized as Other Expense. At the present time, we cannot predict the ultimate outcome of this matter, including whether some or all of the C$33 million drawn on the letter of credit will be payable to us or whether any additional amounts will have to be paid related to the termination of the contract. We expect that we and the third party will disagree as to what are the remaining obligations under the relevant agreement and the length of the remaining term of the agreement and as to the remedies and defenses available to the parties. While we expect to vigorously dispute the amount, we expect that the third party will claim to be entitled to up to approximately C$126 million (including the proceeds of the letter of credit) as the aggregate of the monthly tolls for firm capacity for the alleged remainder of the term of the relevant agreement. Note 1 to this Quarterly Report contains a description of our claims reconciliation process associated with the bankruptcy proceedings. On April 15 and May 8, 2015, the Bankruptcy Court issued orders allowing us to reject certain executory contracts effective March 17 and April 1, 2015 and the total estimated allowable claim under these contracts has been included in Liabilities Subject to Compromise and Reorganization Items, net as appropriate. The reductions impacted our GPT contracts included in the contractual obligation table included in our 2014 Form 10-K and reduced our total payments due over the life of the contracts as of the date the contracts were rejected by approximately $39 million . We renegotiated an NGL GPT contract in our Barnett Shale Asset effective April 2015, which reduced our GPT contracts included in the contractual obligation table included in our 2014 Form 10-K over the life of the contract by approximately $100 million . Note 13 to the consolidated financial statements in our 2014 Annual Report on Form 10-K contains a more complete description of our contractual obligations, commitments and contingencies for which there are no other significant updates during the quarter ended June 30, 2015 .

Equity Method Investments and Joint Ventures [Abstract]
Fortune Creek	FORTUNE CREEK Note 14 to the consolidated financial statements in our 2014 Annual Report on Form 10-K contains additional information on Fortune Creek. We do not expect to be able to satisfy the capital expenditure or equipment purchase requirements described in our 2014 Annual Report on Form 10-K with our cash on hand, committed financing or cash flow from operations and will need to obtain additional debt or equity financing or sell assets, which we may not be able to do on satisfactory terms, or at all. We committed gas production from our Horn River Asset for ten years beginning 2012. KKR contributed C$125 million cash in exchange for a 50% interest in Fortune Creek. Our Canadian subsidiary has responsibility for the day-to-day operations of Fortune Creek. The firm gathering agreement with Fortune Creek is guaranteed by us. If our subsidiary does not pay its minimum volume obligations under the gathering agreement or meet the capital expenditure requirements, KKR has the right to liquidate the partnership and consequently we have recorded the funds contributed by KKR as a liability in our consolidated financial statements. We recognize accretion expense to reflect the rate of return earned by KKR via its investment. Fortune Creek has made cash distributions to KKR, which are reported as cash used in financing activities. QRCI did not make an approximately C$1.6 million payment due at the end of June 2015 pursuant to the gathering agreement with Fortune Creek. As a result, among other things: (i) Fortune Creek may discontinue transporting QRCI's gas until all amounts owing are repaid (although, as previously disclosed, production was previously shut-in due to the termination of a third-party gathering and processing agreement in March 2015); (ii) if the non-payment continues for more than 90 days after a written demand therefor, subject to certain existing contracts for the sale of gas, Fortune Creek may enforce the lien granted by QRCI to Fortune Creek on the natural gas belonging to QRCI while it is in the Maxhamish Pipeline and in Fortune Creek's possession; (iii) Fortune Creek has certain set-off rights against QRCI; (iv) if the non-payment continues for 180 days (or 60 days following a written notice by the other partner), we will not be entitled to receive partnership distributions or vote with respect to partnership matters until the non‑payment is cured and Fortune Creek may be dissolved or our partnership interest in Fortune Creek may be purchased by the other partner; and (v) the operating agreement could be terminated by Fortune Creek. QRCI also did not make the approximately C$1.6 million payment due at the end of July 2015 and does not currently intend to make future payments. Past due amounts under the gathering agreement bear interest compounded monthly at prime plus 2% . We are in discussions with KKR in connection with the issues related to Fortune Creek; however, we may not reach a resolution in the near-term, or at all. Based on a quarterly analysis of the partners’ equity at risk, we have determined the partnership to be a VIE. Further, based on our ability to direct the activities surrounding the production of natural gas and our direct management of the operations of the Fortune Creek facilities, we have determined we are the primary beneficiary and, therefore, we consolidate Fortune Creek. We will continue to evaluate this assessment in light of our bankruptcy filings in the U.S., breach of contract due to non-payment and our liquidity constraints in Canada.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION We operate in two geographic areas, the U.S. and Canada, where we are engaged in the exploration and production segment of the oil and gas industry. Additionally, we operate a significantly smaller midstream segment in the U.S. and Canada, where we provide natural gas gathering and processing services, primarily to our U.S. and Canadian exploration and production segments. In Canada, our midstream operation is the Fortune Creek partnership. Revenue earned by Fortune Creek for the gathering and processing of our gas is eliminated on a consolidated basis as is the GPT recognized by our producing properties. Based on the immateriality of our midstream segment, we have combined our U.S. and Canadian midstream information. We evaluate performance based on operating income and property and equipment costs incurred.

Transactions With Related Parties	TRANSACTIONS AND OTHER MATTERS WITH RELATED PARTIES As of June 30, 2015 , members of the Darden family and entities controlled by them beneficially owned approximately 25% of our outstanding common stock. Glenn Darden and Anne Darden Self are officers and directors of Quicksilver. Payments received from Mercury, a company owned by members of the Darden family, for sublease rentals and administrative services were less than $0.1 million for the first six months of 2015 and 2014 . In May 2013, we entered into an agreement with Thomas F. Darden, brother of Glenn Darden and Anne Darden Self, with respect to Mr. Darden’s retirement and Mr. Darden’s provision of consulting services following his retirement. Mr. Darden retired as an employee on December 31, 2013, and resigned from the board of directors effective September 1, 2014. During the first six months of 2015 , consulting fee payments of $45,000 and office allowance payments of $12,500 were made to Mr. Darden. During the first six months of 2014, consulting fee payments of $272,000 , office allowance payments of $75,000 and COBRA payments of $39,000 were made to Mr. Darden. Additionally, in accordance with the agreement, and following the execution and non-revocation of a release agreement satisfactory to us, in March 2014, we paid Mr. Darden a cash bonus of $286,650 and an equity bonus in the form of 72,662 fully vested shares having a grant date fair value equal to $191,100 . We did not make consulting fee payments of $90,000 or office allowance payments of $25,000 for February or March 2015 and, on April 15, 2015, the Bankruptcy Court entered an order authorizing our rejection of the agreement effective as of March 17, 2015. The remaining amount owed under the agreement was $1.3 million . These amounts are included in Liabilities Subject to Compromise on the balance sheet as of June 30, 2015.

However, pursuant to the Forbearance Agreements, the administrative agent and certain lenders agreed to, among other things, forbear from exercising their rights and remedies in connection with specified defaults under the Amended and Restated Canadian Credit Facility, including events of default related to our Chapter 11 filings or the failure to comply with the financial covenants, until the earlier of September 16, 2015 or certain other events specified in the Forbearance Agreements. The following table sets forth the minimum EBITDAX covenant for the Amended and Restated U.S. Credit Facility immediately prior to the Chapter 11 filings and for the Amended and Restated Canadian Credit Facility: Minimum EBITDAX Covenant (in millions) Nine months ending June 30, 2015 87.25 Twelve months ending September 30, 2015 120.5 Twelve months ending December 31, 2015 122.0 Immediately prior to the Chapter 11 filings, the minimum required interest coverage ratio for the Amended and Restated U.S. Credit Facility for the first and second quarters of 2016 was 1.50 and 2.00 , respectively. The minimum required interest coverage ratio for the Amended and Restated Canadian Credit Facility for the first and second quarters of 2016 is 1.50 and 2.00 , respectively. (8) Immediately prior to acceleration as a result of our Chapter 11 filings, our indentures required us to reinvest or repay senior debt with net cash proceeds from certain asset sales within one year. (9) The information presented in this table is qualified in all respects by reference to the full text of the covenants, provisions and related definitions contained in the documents governing the various components of our debt. (10) The estimated fair value is determined using market quotations based on recent trade activity for fixed rate obligations (“Level 2” inputs). Our Second Lien Term Loan and Second Lien Notes feature variable interest rates and we estimate their fair value by using market quotations based on recent trade activity (“Level 3” input). We consider our Combined Credit Agreements, which have a variable interest rate, to have a fair value equal to their carrying value (“Level 1” input).

[1]	Borrowings under the Amended and Restated U.S. Credit Facility, Second Lien Term Loan and Second Lien Notes due 2019 are guaranteed by certain of Quicksilver’s domestic subsidiaries and are secured (on a first priority basis with respect to the Amended and Restated U.S. Credit Facility and on a second priority basis with respect to the Second Lien Term Loan and the Second Lien Notes due 2019) by 100% of the equity interests of each of Cowtown Pipeline Management, Inc., Cowtown Pipeline Funding, Inc., Cowtown Gas Processing L.P., Cowtown Pipeline L.P., Barnett Shale Operating LLC, Silver Stream Pipeline Company LLC, QPP Parent LLC and QPP Holdings LLC (collectively, the “Domestic Pledged Equity”), 65% of the equity interests of QRCI and Quicksilver Production Partners Operating Ltd. (with respect to the Amended and Restated U.S. Credit Facility, on a ratable basis with borrowings under the Amended and Restated Canadian Credit Facility) and the majority of Quicksilver's domestic proved oil and gas properties and related assets, (the “Domestic Pledged Property”). Borrowings under the Amended and Restated Canadian Credit Facility are guaranteed by Quicksilver and certain of its domestic subsidiaries and are secured by the Domestic Pledged Equity, the Domestic Pledged Property, 100% of the equity interests of QRCI (65% of which is on a ratable basis with the borrowings under the Amended and Restated U.S. Credit Facility) and any Canadian restricted subsidiaries, under the Amended and Restated Canadian Credit Facility, and 65% of the equity interests of Quicksilver Production Partners Operating Ltd. (which is on a ratable basis with the borrowings under the Amended and Restated U.S. Credit Facility) and the majority of QRCI's oil and gas properties and related assets. The other debt presented is based upon structural seniority and priority of payment.
[2]	The principal amount included in the table for the Combined Credit Agreements represents the global borrowing base immediately prior to the Chapter 11 filings.
[3]	Immediately prior to acceleration as a result of the Chapter 11 filings, the Combined Credit Agreements were required to be repaid 91 days prior to the maturity of the Senior Subordinated Notes, the Second Lien Term Loan or the Second Lien Notes due 2019, if on the applicable date any amount of such debt remained outstanding. Immediately prior to acceleration as a result of the Chapter 11 filings, the Second Lien Term Loan and Second Lien Notes due 2019 were required to be repaid (1) 91 days prior to the maturity of the 2019 Senior Notes if more than $100 million of the 2019 Senior Notes remained outstanding and (2) 91 days prior to the maturity of the Senior Subordinated Notes if on the applicable date the amount remaining outstanding was greater than $100 million. Immediately prior to acceleration as a result of the Chapter 11 filings, as then structured and assuming no changes in the amounts outstanding, amounts outstanding under the Combined Credit Agreements would have been due on October 2, 2015 and the Second Lien Term Loan and Second Lien Notes would have been due on January 1, 2016.
[4]	Represents the weighted average borrowing rate payable to lenders on our Combined Credit Agreement as of June 30, 2015.
[5]	Immediately prior to the Chapter 11 filings, amounts outstanding under the Amended and Restated Canadian Credit Facility bore interest, at our election, at (i) the CDOR Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 2.75% and 3.75%, (ii) the Canadian Prime Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 1.75% and 2.75%, (iii) the U.S. Prime Rate (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 1.75% and 2.75% or (iv) adjusted LIBOR (as defined in the Amended and Restated Canadian Credit Facility) plus an applicable margin between 2.75% and 3.75%. We also pay a per annum fee on the LC Exposure (as defined in the Amended and Restated Canadian Credit Facility) of all letters of credit issued under the Amended and Restated Canadian Credit Facility equal to the applicable margin with respect to Eurodollar loans, and a commitment fee on the unused availability under the Amended and Restated Canadian Credit Facility of 0.50%.
[6]	Immediately prior to the Chapter 11 filings, amounts outstanding under the Amended and Restated U.S. Credit Facility bore interest, at our election, at (i) adjusted LIBOR (as defined in the Amended and Restated U.S. Credit Facility) plus an applicable margin between 2.75% and 3.75%, or (ii) ABR (as defined in the Amended and Restated U.S. Credit Facility), which is the greatest of (a) the prime rate announced by JPMorgan, (b) the federal funds rate plus 0.50% and (c) adjusted LIBOR for an interest period of one month plus 1.00%, plus, in each case under scenario (ii), an applicable margin between 1.75% and 2.75%. We also pay a per annum fee on the LC Exposure (as defined in the Amended and Restated U.S. Credit Facility) of all letters of credit issued under the Amended and Restated U.S. Credit Facility equal to the applicable margin with respect to Eurodollar loans, and a commitment fee on the unused availability under the Amended and Restated U.S. Credit Facility of 0.50%.
[7]	The financial covenants and significant restrictive covenants were applicable to the Combined Credit Agreements immediately prior to the Chapter 11 filings and remain applicable to the Amended and Restated Canadian Credit Facility. However, pursuant to the Forbearance Agreements, the administrative agent and certain lenders agreed to, among other things, forbear from exercising their rights and remedies in connection with specified defaults under the Amended and Restated Canadian Credit Facility, including events of default related to our Chapter 11 filings or the failure to comply with the financial covenants, until the earlier of September 16, 2015 or certain other events specified in the Forbearance Agreements.The following table sets forth the minimum EBITDAX covenant for the Amended and Restated U.S. Credit Facility immediately prior to the Chapter 11 filings and for the Amended and Restated Canadian Credit Facility: Minimum EBITDAX Covenant (in millions)Nine months ending June 30, 201587.25Twelve months ending September 30, 2015120.5Twelve months ending December 31, 2015122.0Immediately prior to the Chapter 11 filings, the minimum required interest coverage ratio for the Amended and Restated U.S. Credit Facility for the first and second quarters of 2016 was 1.50 and 2.00, respectively. The minimum required interest coverage ratio for the Amended and Restated Canadian Credit Facility for the first and second quarters of 2016 is 1.50 and 2.00, respectively.
[8]	The information presented in this table is qualified in all respects by reference to the full text of the covenants, provisions and related definitions contained in the documents governing the various components of our debt.
[9]	Immediately prior to acceleration as a result of our Chapter 11 filings, our indentures required us to reinvest or repay senior debt with net cash proceeds from certain asset sales within one year.
[10]	The estimated fair value is determined using market quotations based on recent trade activity for fixed rate obligations (“Level 2” inputs). Our Second Lien Term Loan and Second Lien Notes feature variable interest rates and we estimate their fair value by using market quotations based on recent trade activity (“Level 3” input). We consider our Combined Credit Agreements, which have a variable interest rate, to have a fair value equal to their carrying value (“Level 1” input).
