Explanatory Statement

Under the full cost method of accounting, the Company’s U.S.-based exploration and production assets are considered a single asset. The 2007 fourth quarter divestiture of the Northeast Operations, therefore, represents a fractional divestiture of a single asset, which precludes recording the applicable portion of the Northeast Operations’ 2007 results of operations as discontinued operations within the consolidated financial statements.

Forward-Looking Information

Certain statements contained in this report and other materials we file with the SEC, or in other written or oral statements made or to be made by us, other than statements of historical fact, are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements give our current expectations or forecasts of future events. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements. They can be affected by assumptions used or by known or unknown risks or uncertainties. Consequently, no forward-looking statements can be guaranteed. Actual results may vary materially. You are cautioned not to place undue reliance on any forward-looking statements. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

•		the conditions to the completion of the Alliance Transaction, as set for in the purchase and sale agreements providing for the Alliance Transaction;

•		the availability and terms of the financing we intend to procure in order to fund a portion of the purchase price for the Alliance Transaction;

•		changes in general economic conditions;

•		fluctuations in natural gas, NGL and crude oil prices;

•		failure or delays in achieving expected production from exploration and development projects;

•		uncertainties inherent in estimates of natural gas, NGL and crude oil reserves and predicting natural gas, NGL and crude oil reservoir performance;

•		effects of hedging natural gas, NGL and crude oil prices;

•		competitive conditions in our industry;

•		actions taken by third parties, including operators, processors and transporters;

•		changes in the availability and cost of capital;

•		delays in obtaining oilfield equipment and increases in drilling and other service costs;

•		operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control;

•		the effects of existing and future laws and governmental regulations; and

•		the effects of existing or future litigation

This list of factors is not exhaustive, and new factors may emerge or changes to these factors may occur that would impact our business. Additional information regarding these and other factors may be contained in our filings with the SEC, especially on Forms 10-K, 10-Q and 8-K. All such risk factors are difficult to predict, and are subject to material uncertainties that may affect actual results and may be beyond our control.

All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements.

QUICKSILVER RESOURCES INC.
NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS
UNAUDITED

1. ACCOUNTING POLICIES AND DISCLOSURES

The accompanying condensed consolidated interim financial statements of Quicksilver Resources Inc. (“Quicksilver” or the “Company”) have not been audited. In the opinion of the Company’s management, the accompanying condensed consolidated interim financial statements contain all adjustments necessary to present fairly the financial position of the Company as of June 30, 2008 and its results of operations for the three- and six-month periods ended June 30, 2008 and 2007 and cash flows for the six-month periods ended June 30, 2008 and 2007. All such adjustments are of a normal recurring nature. The results for interim periods are not necessarily indicative of annual results.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during each reporting period. Management believes its estimates and assumptions are reasonable; however, actual results could differ from the Company’s estimates.

Certain disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. Accordingly, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2007 Annual Report on Form 10-K.

Certain reclassifications have been made to prior periods to conform to current period presentation.

Stock Split

On January 7, 2008, Quicksilver’s Board of Directors declared a two-for-one stock split of the outstanding common stock effected in the form of a stock dividend. The stock dividend was paid on January 31, 2008, to holders of record at the close of business on January 18, 2008, but had no effect on shares held in treasury. The capital accounts, all share data and earnings per share data included in these condensed consolidated financial statements for all periods presented reflect retrospective application of the January 2008 stock split.

Earnings per Common Share

Basic earnings per common share is computed by dividing the net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed using the treasury stock method, which considers the impact to net income and common shares from the potential issuance of common shares underlying stock options, stock warrants and outstanding convertible securities.

The following is a reconciliation of the weighted average common shares used in the basic and diluted earnings per common share calculations for the three- and six-month periods ended June 30, 2008 and 2007. Outstanding options to purchase 4,802 shares were excluded from the diluted net income per share calculation for the three- and six-month periods ended June 30, 2007 as those options were out-of-the-money and, therefore, considered to be antidilutive. No such antidilutive options were outstanding at June 30, 2008.

Recently Issued Accounting Standards

•		Pronouncements Implemented

		SFAS No. 157, Fair Value Measurements, was issued by the FASB in September 2006. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (“GAAP”) and expands disclosures about fair value measurements. The Statement applies under other accounting pronouncements that require or permit fair value measurement. No new requirements are included in SFAS No. 157, but application of the Statement has changed current practice. On February 12, 2008, the FASB issued FASB Staff Position 157-2 (“FSP 157-2”) which delayed the effective date of SFAS No. 157 for non-financial assets and liabilities. The delay allows companies additional time to consider the effect of various implementation issues that have arisen, or that may arise, from the application of SFAS No. 157. The Company adopted SFAS No. 157 on January 1, 2008 for new fair value measurements of financial instruments, including its derivative instruments, and recurring fair value measurements of non-financial assets and liabilities. All financial instruments are measured using inputs from three levels of fair value hierarchy. The three levels are as follows:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date.

Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

Level 3 inputs are unobservable inputs that reflect the Company’s assumptions about the assumptions that market participants would use in pricing an asset or liability.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. While SFAS No. 159 became effective on January 1, 2008, the Company did not elect the fair value measurement option for any of its financial assets or liabilities.

On April 30, 2007, the FASB issued FASB Staff Position (“FSP”) No. 39-1, Amendment of FASB Interpretation No. 39. The FSP amends paragraph 3 of FIN No. 39 to replace the terms “conditional contracts” and “exchange contracts” with the term

“derivative instruments” as defined in SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. It also amends paragraph 10 of Interpretation 39 to permit a reporting entity to offset fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement that have been offset in accordance with that paragraph. The Company adopted FSP No. 39-1 on January 1, 2008 without significant impact.

•		Pronouncements Not Yet Implemented

		SFAS No. 141 (revised 2007), Business Combinations, “SFAS No. 141(R)” was issued in December 2007. SFAS No. 141(R) replaces SFAS No. 141, Business Combinations, while retaining its fundamental requirements that the acquisition method of accounting be used for all business combinations and for an acquirer to be identified for each business combination. SFAS No. 141(R) defines the acquirer as the entity that obtains control in the business combination and it establishes the criteria to determine the acquisition date. The Statement also requires an acquirer to recognize the assets acquired and liabilities assumed measured at their fair values as of the acquisition date. In addition, acquisition costs are required to be recognized separately from the acquisition. The Statement will apply to any acquisition completed by the Company on or after January 1, 2009, but may not be applied to any acquisition completed prior to January 1, 2009.

		SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51 was issued in December 2007. The Statement amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary (previously referred to as “minority interest”) and for the deconsolidation of a subsidiary. SFAS No. 160 clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as a component of equity in the consolidated financial statements. The Statement also changes the way the consolidated income statement is presented by requiring consolidated net income to be reported at amounts that include the amounts attributable to both the parent and noncontrolling interest. Additionally, SFAS No. 160 establishes a single method for accounting for changes in a parent’s ownership interest in a subsidiary that do not result in deconsolidation. The Statement is effective for the Company beginning January 1, 2009. Management is determining the extent, if any, this adoption will have on the Company’s financial statements in addition to reclassifying the Company’s noncontrolling interests into equity.

		The FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, in March 2008. Under SFAS No. 161, the Company will be required to disclose the fair value of all derivative and hedging instruments and their gains or losses in tabular format and information about credit risk-related features in derivative agreements, counterparty credit risk, and its strategies and objectives for using derivative instruments. SFAS No. 161 is to be applied prospectively by the Company beginning January 1, 2009. The Company expects that application of SFAS No. 161 will affect the Company’s disclosures about its derivative and hedging instruments, but will not impact the Company’s accounting for them.

		In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles, which identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles (GAAP) in the United States of America (the GAAP hierarchy). This Statement is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles. We do not expect the adoption of SFAS 162 to have an impact on our financial statements or related disclosures.

		In May 2008, the FASB issued Staff Position (“FSP”) APB 14-1, “Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)” (“FSP APB 14-1”), which clarifies that convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) are not addressed by paragraph 12 of APB Opinion No. 14, “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants.” In addition, FSP APB 14-1 indicates that issuers of such instruments generally should separately account for the liability and equity components in a manner that will reflect the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. FSP APB 14-1 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. Early adoption is prohibited. We must adopt FSP APB 14-1 beginning in the first quarter of fiscal 2009 and will be required to retroactively present prior period information.

In accordance with the fair value hierarchy described in SFAS No. 157 above, the following table shows the fair value of the Company’s financial assets and liabilities that are required to be measured at fair value as of June 30, 2008.


	FairValue Measurements as of June 30, 2008
										Balance at
	Level 1		Level 2		Level 3		Other			June 30, 2008

Derivative assets	$	—	$	40,743	$	—	$	(40,743	)	$	—

Derivative liabilities	$	—	$	459,723	$	—	$	(40,743	)	$	418,980

The fair value of all derivative instruments included above was estimated using commodity prices quoted in active markets for the periods covered by the derivatives and the value confirmed by a counterparty. Estimates were determined by applying the net differential between the prices in each derivative and market prices for future periods, as adjusted for estimated basis differential, to the volumes stipulated in each contract to arrive at an estimated future value. This estimated future value was discounted on each contract at rates commensurate with federal treasury instruments with similar contractual lives.

The Company hedges a portion of its production revenue using various financial derivatives. All derivatives are evaluated using the hedge criteria established under U.S. accounting standards. If hedge criteria are met, the change in a derivative’s fair value (for a cash flow hedge) is deferred in stockholders’ equity as a component of accumulated other comprehensive loss to the extent the hedge is effective. These deferred gains and losses are recognized into income in the period in which the hedged transaction is recognized in revenues to the extent the hedge is effective. The changes in value of ineffective portions of hedges are recognized currently in earnings.

The Company’s derivative instruments at June 30, 2008 and December 31, 2007 include the Michigan Sales Contract that requires delivery of 25 MMcfd of natural gas at a floor of $2.49 Mcf through March 2009. In December 2007, the Company made a decision to no longer deliver a portion of our natural gas production to supply the contract and recognized a $63.5 million loss at that time. In January 2008, the Company entered into two fixed-price natural gas swaps covering all volumes for the remaining contract period, which served to effectively offset the net earnings exposure for the Company’s remaining obligation under the Michigan Sales Contract. During 2008, the Company has paid $17.8 million of net cash in settlement of obligations for the Michigan Sales Contract.

The change in carrying value of the Company’s derivatives and the contractual fixed-price sale commitments in the Company’s balance sheet since December 31, 2007 resulted from the increase in market prices for natural gas, NGL and oil. The change in fair value of the effective portion of all cash flow hedges was reflected in accumulated other comprehensive income, net of deferred tax effects. All derivative assets and liabilities represent the estimated fair value of contract settlements scheduled to occur over each contract period remaining based on commodity market prices as of the balance sheet date. These amounts are not realized until the monthly period in which the related underlying production is sold.

The estimated fair values of all financial derivatives and contractual fixed-price sale commitments of the Company as of June 30, 2008 and December 31, 2007 are provided below. The carrying values of these derivatives are equal to the estimated fair values for each period presented. The assets and liabilities recorded in the balance sheet are netted where derivatives with both gain and loss positions are held by a single counterparty.

Cash flow hedge derivative liabilities of $250.9 million have been classified as current at June 30, 2008 based on the maturity of the derivative instruments. The effective portion of the derivative liability held in accumulated other comprehensive income that is expected to be reclassified to earnings over the next twelve months is $162.6 million of after-tax net loss.

3. INVESTMENT IN BREITBURN ENERGY PARTNERS L.P.

The Company received common units of BBEP, a publicly traded limited partnership, as partial consideration for the divestiture of properties and assets to BreitBurn Operating, L.P. which closed on November 1, 2007. At March 31, 2008, the Company held approximately 32% of the BBEP common units outstanding. On June 17, 2008, BBEP announced that it had repurchased and retired 14.4 million units, which represented approximately 22% of the units previously outstanding. The resulting reduction in the number of BBEP common units outstanding increased the Company’s ownership to approximately 41% at June 30, 2008.

The Company accounts for its investment in BBEP units using the equity method, utilizing a one quarter lag from BBEP’s publicly-available information. BBEP is primarily engaged in natural gas, NGL and crude oil production in the United States. Quicksilver’s increased ownership of units resulting from the repurchase of outstanding units by BBEP will be reflected in Quicksilver’s results for the quarter ended September 30, 2008.

Summarized unaudited financial information for BBEP is as follows:


				For the Quarter
	As of			Ended
	March 31, 2008			March 31, 2008
	(In thousands)			(In thousands)

			Net loss available to common unitholders	$	(40,867	)

For the quarter ended June 30, 2008, the Company recognized a $10.3 million loss and $4.1 million loss that reflects its share of BBEP’s loss for the quarter and six months ended June 30, 2008, respectively. The Company’s share of BBEP’s loss for the quarter ended March 31, 2008 includes reductions of depletion and depreciation expense and intangible asset amortization. During 2008, the Company has received $20.3 million in distributions from BBEP, including $10.7 million during the second quarter. The Company expects to receive an additional $11.1 million in distributions in August 2008.

At June 30, 2008, the Company’s carrying value for its BBEP common units was $395.8 million inclusive of a $289.5 million gain deferred from the transaction. The market value of the Company’s BBEP units was $461.8 million, or $21.63 per common unit, at June 30, 2008. On July 31, 2008, BBEP units had reduced to a fair value of $17.23 per unit, which may result in the Company’s recognition of an impairment charge during the third quarter of 2008, in the event that the decrease in value is deemed to be other than temporary.

The terms and conditions of the Senior Notes due 2015 require the Company to comply with certain covenants, which limit, among other things, levels of indebtedness, restricted payments, payments of dividends, capital stock repurchases, investments, liens, restrictions on restricted subsidiaries to make distributions, affiliate transactions and mergers and consolidations. Net proceeds from the issuance were $457 million after discount and underwriting and professional service fees.

As of May 9, 2008, the Company’s borrowing base under its senior secured credit facility was increased to $1 billion from $750 million and is subject to a special redetermination on or about September 15, 2008.

6. ASSET RETIREMENT OBLIGATIONS

The Company recognizes the fair value of the liability for legal obligations associated with the retirement of tangible long-lived assets in the period in which it is legally or contractually incurred. When the liability is recognized, an asset retirement cost is capitalized. The liability is accreted to its settlement date fair value over the useful life of the asset, with the associated expense recognized in depletion or depreciation over the useful life of the asset.

The following table provides a reconciliation of the changes in the Company’s estimated asset retirement obligation for the six-month period ended June 30, 2008.

7. INCOME TAXES

During the quarter ended June 30, 2008, there were no changes to the Company’s unrecognized U.S. tax benefits, which totaled $10.0 million at December 31, 2007. If required, interest or penalties will be recognized as a component of interest expense. The Company does not anticipate total unrecognized tax benefits to significantly change due to the settlement of audits or the expiration of statute of limitations.

The Internal Revenue Service completed its audit of the Company’s 2004 Federal income tax return in April 2008. The Company remains subject to examination by the Internal Revenue Service for the years 2001 through 2007. The Company’s subsidiary, QRCI, because of its Canadian tax pool balances, remains subject to examination by the Canada Revenue Agency (“Revenue Canada”) for the years 1999 through 2007.

During the first quarter of 2008, the Company paid $47 million for income taxes for the 2007 tax year, which primarily resulted from the tax-basis gain from the BreitBurn Transaction.

The Company remains subject to a Texas franchise tax featuring a “taxable margin” component. The Company has not recognized any unrecognized tax benefits for the Texas “taxable margin” tax.

8. COMMITMENTS AND CONTINGENCIES

As previously reported in the Company’s 2007 Annual Report on Form 10-K, on October 13, 2006, the Company filed suit in the 342nd Judicial District Court in Tarrant County, Texas against Eagle Drilling, LLC and Eagle Domestic Drilling Operations, LLC (together “Eagle”) regarding three contracts for drilling rigs in which the Company alleges that the first rig furnished by Eagle exhibited operating deficiencies and safety defects and that the other rigs failed to conform to specifications set forth in the drilling contracts. Subsequently, on January 19, 2007, Eagle Domestic Drilling Operations, LLC (“EDDO”) and its parent, Blast Energy Services, Inc. filed for Chapter 11 bankruptcy in the United States Bankruptcy Court for the Southern District of Texas, Houston Division. The Company’s suit against Eagle in Tarrant County was ultimately transferred to the Bankruptcy Court in Houston and was consolidated with the EDDO/Blast bankruptcy. In that case, EDDO has asserted a counterclaim against the Company alleging the Company breached the aforementioned rig contracts and seeking an unspecified amount of actual damages or, alternatively, liquidated damages under the contracts. Based on an order entered on May 13, 2008, the case is now pending before the United States District Court for the Southern District of Texas, Houston Division. It is currently set for trial on September 15, 2008. Separately, on September 17, 2007, Eagle Drilling, LLC, and Rod and Richard Thornton, sued the Company and P. Jeff Cook, the Company’s Executive Vice President-Operations, in the District Court of Cleveland County, Oklahoma for approximately $29 million in damages and an unspecified amount of punitive damages resulting from the Company’s alleged repudiation of the rig contracts mentioned above. Based upon information currently available, the Company believes that the final resolution of these matters will not have a material effect on the Company’s financial condition, results of operations, or cash flows.

The Company had commitments outstanding of approximately $43 million to purchase components for our drilling program as of June 30, 2008. In addition, the Company has approximately $27 million of surety bonds outstanding to fulfill contractual, legal or regulatory requirements. All surety bonds have an annual renewal option.

KGS has entered into agreements with third parties providing for the construction of a natural gas processing plant and natural gas compression equipment for the plant. Progress payments are due to the third parties upon completion of established construction, manufacturing and delivery milestones. During the six months ended June 30, 2008, $38.8 million was paid to the third parties. KGS estimates additional payments of $61.2 million will be made upon completion of specified construction, manufacturing and delivery milestones, with a targeted in-service date during the first quarter of 2009.

The Company is subject to various possible contingencies, which arise primarily from interpretation of federal and state laws and regulations affecting the oil and natural gas industry and contracts to which the Company is a party or is bound. Such contingencies include differing interpretations as to the prices at which natural gas and crude oil sales may be made, the prices at which royalty owners may be paid for production from their leases, environmental issues and other matters. Although management believes it has complied with the various laws and regulations, administrative rulings and interpretations thereof, adjustments could be required as new interpretations and regulations are issued. In addition, production rates, marketing and environmental matters are subject to regulation by various federal and state agencies.

As of June 30, 2008, members of the Darden family, Mercury Exploration Company (“Mercury”) and Quicksilver Energy L.P., entities that are owned by members of the Darden family, beneficially owned approximately 33% of the Company’s outstanding common stock. Thomas F. Darden, Glenn Darden and Anne Darden Self are officers and directors of the Company.

Quicksilver and its associated entities paid $1.1 million in the first six months of both 2008 and 2007 for rent on buildings owned by Pennsylvania Avenue LP (“PALP”), a Mercury affiliate, and WFMG, L.P., a PALP affiliate. Rental rates have been determined based on comparable rates charged by third parties.

Payments received from Mercury for sublease rentals, employee insurance coverage and administrative services during the first six months of 2008 and 2007 totaled $0.1 million.

The Company paid $0.3 million and $0.2 million during the first six months of 2008 and 2007, respectively, for use of an airplane owned by Sevens Aviation, LLC, a company owned indirectly by members of the Darden family. Usage rates are determined based on comparable rates charged by third parties.

On May 20, 2008, the Audit Committee of Quicksilver approved a settlement agreement with Mercury in which Mercury agreed to make payment to the Company of approximately $0.4 million in connection with issues related to the ownership and operation of certain oil and gas properties acquired by the Company from Mercury in 2001, including audit claims received by the Company with respect to certain of the acquired properties and the administration of certain employee benefits by the Company ( the “Mercury Settlement”). The Committee members reviewed the terms of, and relevant facts and circumstances surrounding the Mercury Settlement, as well as the terms of the Company’s Related Party Transaction Policy in approving the settlement.

KGS has agreed to obtain additional easement rights for a total cost of $0.2 million from an affiliate of an entity that beneficially owns more than 5% of KGS’ outstanding units.

The following table summarizes the changes in the production revenues during the quarter ended June 30, 2008 compared with the comparable 2007 period:


	Natural
	Gas			NGL		Oil			Total
	(In thousands)
Revenue for the quarter ended June 30, 2007	$	102,308		$	22,277	$	9,374		$	133,959
Volume changes		(1,866	)		20,064		(1,857	)		16,341
Price changes		29,619			14,558		3,670			47,847


Revenue for the quarter ended June 30, 2008	$	130,061		$	56,899	$	11,187		$	198,147

Natural gas sales increased as a result of a $2.06 per Mcf increase in realized natural gas prices for the second quarter of 2008 as compared to the 2007 period. A small decrease in natural gas sales volumes was attributable to the absence of 6.0 Bcf of natural gas production from the Northeast Operations which were divested in November 2007. Offsetting this decrease was an additional 4.9 Bcf of natural gas sales volumes that were principally attributable to sizeable increases in production in the Barnett Shale in Texas, where a substantial portion of our capital expenditures were deployed. Production in our CBM projects in Canada also increased 0.8 Bcf as a result of the completion of more wells.

The increase in NGL sales was due to production increases of 495 MBbl and realized prices that were $13.93 per barrel higher in the second quarter of 2008 compared to the comparable prior year quarter. Production volumes in the Fort Worth Basin increased due to new wells placed into production subsequent to the second quarter of 2007 and improved NGL recovery. Partially offsetting the Fort Worth Basin and pricing increases was the absence of production from the Northeast Operations.

The increase in oil sales is attributable to higher realized prices partially offset by a net decrease in production. The absence of production from the Northeast Operations was only partially offset by a 62 MBbl increase in Fort Worth Basin oil production.

Other Revenue

Other revenue in the quarter ended June 30, 2008 decreased $2.7 million from the comparable 2007 quarter. The decrease was primarily due to partial ineffectiveness of the derivatives hedging our Canadian production which resulted in a charge of $4.4 million for 2008 second quarter as compared to additional revenue of $1.0 million for the 2007 second quarter. The change in the fair value of the ineffective portion of our Canadian hedges was due to changes in basis differentials during the quarter ended June 30, 2008. Additional KGS third-party processing and transportation revenue of $2.4 million partially offset the partial ineffectiveness charge.

	$	33,560	$	1.56	$	31,989	$	1.69

Production costs increased as a result of a $2.1 million increase in Canadian production costs partially offset by a small decrease in U.S. production costs for the second quarter of 2008.

The small decrease in oil and gas production costs for our U.S. properties was due to the absence of $12.5 million in production expense that resulted from the divestiture of the Northeast Operations in November 2007. That decrease was almost offset by higher production costs in the Fort Worth Basin resulting from the growth of our operations in the Fort Worth Basin where production increased over 120% as a result of additional wells placed into production over the past twelve months. Texas lease operating expenses per Mcfe for the second quarter of 2008 decreased as compared to the 2007 second quarter primarily due to cost containment initiatives and improving leverage of our fixed cost structure over a higher volume base.

Canadian oil and gas production costs increased, in part, because of a 16% increase in production volumes. Canadian expense was also higher in the second quarter of 2008 because of additional gas processing and transportation costs and production overhead expense compared to the second quarter of 2007. Gas processing and transportation costs for the second quarter of 2008 increased approximately $1.2 million. Canadian production overhead increased approximately $0.9 million due primarily to additional compensation and rent costs, and an additional $0.3 million increase that resulted from the currency effects of the stronger Canadian dollar in relation to the U.S. dollar between the two periods.

Total production and ad valorem taxes	$	2,208	$	0.10	$	4,212	$	0.22

Second quarter 2008 production and ad valorem taxes decreased due to the absence of production for the Northeast Operations partially offset by production increases for Texas, where many of our properties are exempt from or carry a lower rate of production tax because of the cost of drilling and completing wells.

Other Operating Costs

Other operating costs, which principally relate to the costs of processing and gathering third-party natural gas in Texas, were $0.7 million for the second quarter of 2008, an increase of $0.4 million from the comparable 2007 amount. The increase was due to higher KGS gathering and processing volumes from third parties for the second quarter of 2008 as compared to the 2007 second quarter.

Total depletion, depreciation and accretion	$	38,920	$	1.81	$	27,905	$	1.47

Higher depletion for the second quarter of 2008 resulted from a 27% increase in the depletion rate and a 13% increase in sales volumes. Our higher depletion rate for the second quarter of 2008 resulted from significant increases in estimated future capital expenditures and the costs of proved reserves added from our Canadian and Fort Worth Basin properties. The $1.3 million increase in depreciation for the second quarter of 2008 as compared to the 2007 second quarter was primarily associated with additions of Fort Worth Basin field compression, gas processing facilities and gathering system assets partially offset by the absence of $1.1 million of depreciation expense for divested Northeast Operations depreciable assets. On a unit cost basis, depreciation increased due to the impact of straight-line recognition of plant, pipeline and other surface equipment over higher total production.

Total general and administrative expense	$	15,382	$	0.72	$	10,298	$	0.54

General and administrative expense for the second quarter of 2008 increased over the 2007 period due, in part, to a $3.9 million increase in employee compensation and benefits that included $0.9 million of non-cash expense for vesting of stock-based compensation and $1.2 million in performance-based compensation to be paid in the fourth quarter of 2008 or first quarter of 2009. The remaining increase in employee compensation is related to additional headcount which was necessary to bring our infrastructure to a level needed to accommodate the current and anticipated future growth in our production. Expenses for legal, accounting and other professional services increased general and administrative expense by approximately $0.6 million for the 2008 second quarter as compared to the 2007 second quarter. Higher costs for the second quarter of 2008 were the result of business improvement initiatives, additional regulatory filing requirements, additional investor relations activity and KGS’ ongoing costs associated with activities and requirements for a publicly-traded partnership.

Interest Expense

Interest expense for the second quarter of 2008 was $14.5 million, net of capitalized interest of $1.9 million, which was a decrease of $3.7 million compared to the second quarter of 2007. Interest expense for the second quarter of 2008 was lower than the 2007 second quarter primarily because of an additional $1.7 million of capitalized interest and a decrease in the average interest rate on our debt balances outstanding.

Our provision for income taxes for the second quarter of 2008 increased from the prior year period due to a $13.0 million increase in federal income tax expense associated with higher pretax earnings. The remaining $2.8 million increase was due to Texas margin deferred income taxes and tax credits for research and development in Canada that we recognized in 2007.

The following table summarizes the changes in the production revenues during the six-month period ended June 30, 2008 compared with the comparable 2007 period:


	Natural
	Gas			NGL		Oil			Total
				(In thousands)
Revenue for the six months ended June 30, 2007	$	197,870		$	32,368	$	17,013		$	247,251

Price changes		46,124			27,248		6,710			80,082

Revenue for the six months ended June 30, 2008	$	234,547		$	101,953	$	20,003		$	356,503

Natural gas sales increased as a result of a $1.67 per Mcf increase in realized natural gas prices for the first half of 2008 as compared to the 2007 six-month period. When compared to the 2007 period, natural gas sales volumes decreased primarily as a result of the absence of 12.2 Bcf of natural gas production from the Northeast Operations which were divested in November 2007. Wells placed into production subsequent to June 30, 2007 resulted in additional production from the Fort Worth Basin of 9.3 Bcf and 1.4 Bcf from our CBM projects in Canada.

Our NGL sales for the six months ended June 30, 2008 increased as a result of both higher production volumes and realized sales prices. The production volume increase was due to new wells placed into production subsequent to June 30, 2007 and improved NGL recovery from our newest processing facility in the Fort Worth Basin that began operations in March 2007. More favorable realized pricing during the 2008 period also impacted NGL sales. Partially offsetting the Fort Worth Basin and pricing increases was the absence of production from the Northeast Operations.

Oil sales for the period ended June 30, 2008 increased due to higher realized prices partially offset by a net decrease in production. The absence of production from the Northeast Operations was only partially offset by a 109 MBbl increase in Fort Worth Basin oil production.

Other Revenue

Other revenue in the six months ended June 30, 2008 decreased $6.8 million from the comparable 2007 period. The derivatives hedging our production were partially ineffective, due primarily to changes in basis differentials, and resulted in a charge of $9.9 million for the six months ended June 30, 2008 as compared to additional revenue of $1.0 million for the 2007 six-month period. Additional KGS third-party processing and transportation revenue of $3.5 million partially offset the partial ineffectiveness charge.

Oil and gas production costs increased for the first six months of 2008 from the comparable 2007 period due to increases in both the U.S. and Canada. In general, these increases are attributable to the aggregate 14% increase in production, which was achieved despite the absence of production attributable to the divested Northeast Operations.

Oil and gas production costs for the United States increased as a result of the growth of our Fort Worth Basin operations. The $25.9 million increase in Texas oil and gas production expense was primarily the result of a 147% increase in production volumes for the 2008 six-month period as compared to the 2007 six-month period. Texas oil and gas production expense per Mcfe for the first six months of 2008 decreased 4% when compared to the 2007 six-month unit cost primarily due to cost containment initiatives and improving cost leverage across our increased production. Partially offsetting the increase in U.S. oil and gas production costs was a $25.4 million decrease in production expense that resulted from the divestiture of the Northeast Operations in November 2007.

Canadian oil and gas production costs increased in the first six months of 2008 due, in part, to a 14% increase in production volumes. Canadian gas processing costs for the 2008 six-month period increased approximately $2.5 million from the comparable prior year period. Additionally, production overhead expense for the first half of 2008 increased $2.3 million as compared to the first half of 2007. The increase in production overhead was attributable to higher compensation and rent costs of approximately $1.1 million with the remaining $1.2 million increase resulting primarily from currency effects that reflected the strengthening of the Canadian dollar in relation to the U.S. dollar between the two periods.

Total production and ad valorem taxes	$	4,867	$	0.12	$	8,702	$	0.24

Production and ad valorem taxes for the 2008 period decreased due to the absence of production for the Northeast Operations partially offset by production and infrastructure increases for Texas, where many of our properties are exempt from or carry a lower rate of production tax because of the cost of drilling and completing wells.

Other Operating Costs

Other operating costs, which relate to the cost of processing and gathering third-party natural gas in Texas, were $1.9 million for the first six months of 2008. The $0.9 million increase from the 2007 six-month period was the result of higher KGS gathering and processing volumes from third parties for the 2008 six-month period.

Total depletion, depreciation and accretion	$	73,979	$	1.82	$	52,499	$	1.47

Depletion for the first six months of 2008 increased from the comparable 2007 period. Higher depletion resulted from a 27% increase in the depletion rate and a 14% increase in sales volumes. Our higher depletion rate for the first half of 2008 resulted from significant increases in estimated future capital expenditures and the costs of proved reserves added from our Canadian and Fort Worth Basin properties. The $2.6 million increase in depreciation for the 2008 period as compared to the 2007 six-month period was primarily associated with additions of Fort Worth Basin field compression, gas processing facilities and gathering system assets partially offset by the absence of $2.1 million of depreciation expense for Northeast Operations depreciable assets. Depreciation for 2008 on a unit cost basis increased due to the additional surface equipment, compression equipment and gathering networks placed into service since June 30, 2007.

General and Administrative Expense

	2008				2007
	(In thousands, except per unit amounts)

Total general and administrative expense	$	30,797	$	0.76	$	19,996	$	0.56

General and administrative expense increased $0.20 per Mcfe for the 2008 period from the comparable 2007 period. The most significant increase in general and administrative expense for the first half of 2008 was a $7.4 million increase in employee compensation and benefits, including $2.0 million of non-cash expense for vesting of stock-based compensation and $3.0 million in performance-based compensation to be paid in the fourth quarter of 2008 and first quarter of 2009. The remaining $2.4 million increase in employee compensation is related to additional headcount which was necessary to bring our infrastructure to a level needed to accommodate the current and anticipated growth in our production. Office rent and overhead costs also increased $0.7 million. Fees for legal, accounting and other professional services increased general and administrative expense by approximately $1.7 million for the 2008 period as compared to the 2007 period. Higher costs for the 2008 six-month period were the result of increasing investor relations activities, additional regulatory filing requirements, business improvement initiatives and KGS’ ongoing costs associated with activities and requirements for a publicly-traded partnership.

Interest Expense

Interest expense for the first six months of 2008 was $26.3 million, net of capitalized interest of $3.6 million, which was a decrease of $6.9 million compared to the first six months of 2007. Interest expense for the first half of 2008 was lower than the comparable 2007 period in part because of an additional $2.7 million of capitalized interest and a decrease in the average interest rate on our debt balances outstanding.

Income Tax Expense


	Six Months Ended

	2008			2007
Income tax (in thousands)	$	52,468		$	24,065
Effective tax rate		35.3	%		30.5	%

The provision for income taxes for the first six months of 2008 increased from the prior year period due largely to an increase in pretax income for the 2008 period. The increase in the effective tax rate for the 2008 period resulted from higher non-deductible expenses related to officers’ compensation and the absence of tax credits for research and development in Canada that were recognized in the first half of 2007. Income tax also increased by $2.2 million for Texas margin deferred income taxes.

LIQUIDITY, CAPITAL RESOURCES AND FINANCIAL POSITION


	For the Six Months Ended

	(In thousands)
Net cash provided by operating activities	$	136,611		$	154,548

Net cash provided by financing activities		466,571			283,883
Effect of exchange rate changes in cash		447			1,884

Net cash provided by operations decreased compared to the same period in 2007 primarily due to a $47 million payment for 2007 U.S. federal income tax as compared to no such payments in the 2007 period. Net income of $94.6 million for the first six months

of 2008 was $40.0 million higher than net income for the first six months of 2007. Operating cash flow was also adversely impacted by increases in working capital.

Our principal sources of cash are revenues generated by our production. Price collars and swaps covered approximately 68% of our total production for the six months ended June 30, 2008. As of July 31, 2008, we had price collars or fixed price swaps hedging our anticipated natural gas, oil and NGL production of approximately 178 MMcfd, 1,000 Bbld and 3,000 Bbld, respectively, for the remainder of 2008. We have hedged approximately 190 MMcfd and 160 MMcfd of our anticipated 2009 and 2010 natural gas sales, respectively, using price collars and fixed-price swaps.

During the first six months of 2007, the Northeast Operations generated cash of approximately $45.5 million. Distributions on our BBEP units were $20.3 million during the comparable 2008 period and have been reported as investing cash flows.

During the first six months of 2008, we paid $650.4 million for property and equipment, an increase of approximately $208 million from the comparable 2007 period. Property and equipment acquired (payments for property and equipment plus noncash changes in working capital associated with property and equipment) for the 2008 period totaled $649.2 million, which consisted primarily of $531.0 million expended for exploration and development activities and $106.8 million expended for our Fort Worth basin gas processing and gathering operations. Of the $531.0 million incurred for exploration and development, $19.7 million and $53.8 million was spent for acquisition of non-producing leasehold in the United States and Canada, respectively, inclusive of our acquisitions of acreage in the Horn River Basin in northeast British Columbia.

Net cash provided by financing activities for the six months ended June 30, 2008 totaled $466.6 million. On June 27, 2008, we issued $475 million in Senior Notes due in 2015 which generated net proceeds of $457 million after discount and underwriting and professional fees. The Senior Notes due 2015 bear interest at an annual rate of 8.25% payable semiannually on February 1 and August 1 of each year. All net proceeds from the transaction were used to reduce existing borrowings outstanding under our senior credit facility. The loan agreements for the senior credit facility prohibit the declaration or payment of dividends by us and contain certain financial covenants, which, among other things, require the maintenance of a minimum current ratio and a minimum earnings (before interest, taxes, depreciation, depletion, amortization, non-cash income and expense and exploration costs) to interest ratio. As of May 9, 2008, the borrowing base under our senior secured credit facility was increased to $1 billion from $750 million and is subject to a special redetermination on or about September 15, 2008. At June 30, 2008, approximately $730 million was available for borrowing under our senior secured credit facility, and we were in compliance with all of our covenants.

KGS’ $150 million senior secured credit facility had $55.3 million of borrowings outstanding at June 30, 2008, and KGS was in compliance with all of its covenants. Approximately $84.3 million was available for borrowing under the KGS senior secured credit facility at June 30, 2008.

As of June 30, 2008 and December 31, 2007, we had the following total capitalization:

After funding estimated remaining 2008 capital expenditures of approximately $450 million, a part of the cash portion of the purchase price payable in the Alliance Transaction (see below), net operating costs and interest expense, we expect the borrowings outstanding under our senior secured credit facility and the KGS credit facility to increase by approximately $450 million to $500 million during the second half of 2008.

Financial Position

The following impacted our balance sheet as of June 30, 2008, as compared to our balance sheet as of December 31, 2007:

	•		An increase of over $560.3 million in our net property, plant and equipment assets, which includes approximately $649.2 million in capital costs incurred principally for development, exploitation and exploration of our oil and gas properties as well as additional natural gas processing and gathering system assets.

	•		We incurred additional long-term debt of $475 million, primarily as a result of our capital expenditure program and partially offset by cash flow from operations. Borrowings were drawn from our senior secured credit facility and the KGS credit facility. A portion of the borrowings under our senior secured credit facility were repaid with the proceeds from the issuance of our Senior Notes due 2015.

	•		Our current and non-current derivative liabilities have increased $233.0 million and $105.6 million, respectively. Our current derivative liabilities include $45.6 million for the estimated fair value of the Michigan Sales Contract, net of the swap valuation of $38.7 million for the fixed-price swaps entered into in January 2008 to offset our net earnings exposure for the remaining contract period under the Michigan Sales Contract. All other changes in derivative assets and liabilities reflect changes in the estimated fair value of our cash-flow hedges. The changes are the result of higher pricing of natural gas, crude oil and NGLs compared to our derivative contracts at June 30, 2008 as market prices have generally trended upward. Additionally, our current deferred tax asset increased $79.0 million as a result of the increase in estimated fair value of our natural gas, crude oil and NGL financial derivatives.

Alliance Transaction

On July 7, 2008, we announced that we had entered into agreements to acquire leasehold, royalty and midstream assets, associated with the Barnett Shale in northern Tarrant and southern Denton counties of Texas, for consideration of $1 billion in cash and $307 million in Quicksilver Resources common stock, subject to customary closing adjustments. We expect to fund the cash portion of the transaction through a combination of cash on hand, borrowings under both a proposed $700 million five-year second-lien term loan facility and our existing credit facility. We expect that the proposed second-lien term loan will be issued at 98% of face value and have an initial interest rate of LIBOR plus 4.5% per annum, with an increase of 0.25% every 3 months after the second anniversary date of the note. The common stock issued in the transaction will be valued based on the volume weighted-average price for the 15 consecutive trading days immediately prior to the third trading day prior to closing the transaction which is scheduled to occur on August 8, 2008. We expect that the number of shares to be issued pursuant to the transaction will be approximately 10.7 million.

Upon completion, the Alliance Transaction will result in our acquisition of interests entitling us to an average net revenue interest of approximately 90% in production from approximately 13,000 acres in northern Tarrant and southern Denton counties. Based upon information provided to us by the sellers and our own internal estimates, we believe that the acquisition will add natural gas

production of 40 MMcfd, 350 Bcf of proved natural gas reserves and a significant amount of additional resource potential to our existing base assets. The transaction will also increase the absolute value of operating expenses and severance taxes, although the impact of such costs on a unit basis is still to be determined. Furthermore, the transaction will likely cause our consolidated depletion, depreciation and amortization rate to increase from $1.82 per Mcfe for the first half of 2008 to a rate of $2.15 per Mcfe to $2.20 per Mcfe for the second half of 2008.

Contractual Obligations and Commercial Commitments

Significant changes to our contractual obligations and commercial commitments not otherwise disclosed as of June 30, 2008 include the following:

	•		We have commitments of approximately $43 million outstanding to purchase components for our drilling program; and,

	•		We have issued additional surety bonds to fulfill contractual, legal or regulatory requirements bringing the total of surety bonds outstanding to approximately $27 million.

Accounting Developments

The information regarding recent accounting pronouncements is included in Note 1 to our condensed consolidated interim financial statements included in Item 1 of this quarterly report.

Critical Accounting Estimates

Management’s discussion and analysis of financial condition and results of operations are based on our condensed consolidated financial statements and related footnotes contained within this quarterly report. Our more critical accounting estimates used in the preparation of the consolidated financial statements were discussed in our 2007 Annual Report on Form 10-K. These critical estimates, for which no significant changes have occurred in the six months ended June 30, 2008, include estimates and assumptions for:

	•		Oil and gas properties, including underlying reserves and cost capitalization limitations;

	•		Derivative instruments;

	•		Asset retirement obligations;

	•		Stock-based compensation;

	•		Income taxes;

	•		Equity earnings from BreitBurn Energy Partners; and,

	•		Revenue.

The process of preparing financial statements in conformity with GAAP requires the use of estimates and assumptions to determine certain of the assets, liabilities, revenues and expenses. These estimates and assumptions are based upon what we believe is the best information available at the time of the estimates or assumptions. The estimates and assumptions could change materially as conditions within and beyond our control change. Accordingly, actual results could differ materially from those estimates.


ITEM 3.		Quantitative and Qualitative Disclosures About Market Risk

We have established policies and procedures for managing risk within our organization, including internal controls. The level of risk assumed by us is based on our objectives and capacity to manage risk.

Our primary risk exposure is related to fluctuations in natural gas, oil and NGL commodity prices. We have mitigated the risk of adverse price movements through the use of swaps and collars; however, we have also limited future gains from favorable movements.

Commodity Price Risk

We enter into financial derivative contracts to mitigate our exposure to commodity price risk associated with anticipated future natural gas, NGL and crude oil production. As of July 31, 2008, approximately 118 MMcfd and 60 MMcfd of natural gas price collars and swaps, respectively, have been put in place to hedge a portion of our anticipated production for the remainder of 2008. Additionally, we have used fixed-price swaps and swaps to hedge 3,000 Bbld of NGL and 1,000 Bbld of oil, respectively, of our anticipated production for the remainder of 2008. Anticipated 2009 and 2010 natural gas production of approximately 190 MMcfd and 160 MMcfd, respectively, has been hedged using price collars and swaps, respectively. We believe we will have more predictability of our natural gas, oil and NGL revenues as a result of these financial derivative contracts.

Utilization of our hedging program may result in natural gas, NGL and crude oil realized prices varying from market prices that we receive from the sale of natural gas, NGL and crude oil. Our revenue from natural gas, NGL and crude oil production was $34.6 million lower and $21.4 million higher as a result of our hedging programs for the first six months of 2008 and 2007, respectively. Other revenue was $9.9 million lower and $1.0 million higher as a result of hedging ineffectiveness for the six-month periods ending June 30, 2008 and 2007, respectively.

The following table summarizes our open derivative positions as of June 30, 2008 related to our future natural gas, NGL and crude oil production.

				Total		$	(372,840	)

At June 30, 2008, we had nine months remaining on our obligation to deliver 25 MMcfd of natural gas under the Michigan Sales Contract. In December 2007, we determined we would no longer deliver a portion of our natural gas production to supply the

contractual volumes under the Michigan Sales Contract. At that time, we recognized a loss of $63.5 million for the fair value of the Michigan Sales Contract through the end of its term in March 2009. In January 2008, we entered into two fixed-price natural gas swaps covering all volumes for the remaining contract period, which served to effectively offset the net earnings exposure of our remaining obligation under the Michigan Sales Contract. During 2008, we have made $17.8 million of net cash payments for settlement of obligations for the Michigan Sales Contract. The following table summarizes these open positions as of June 30, 2008.

Credit Risk

During the six months ended June 30, 2008, we had NGL sales of $96.2 million to two parties. These sales represent 27% of our consolidated production revenue during the six months then ended. In accordance with our established credit policy, we review each counterparty for credit worthiness prior to the extension of credit and regularly monitor our exposure to all counterparties by reviewing credit ratings, financial statements and credit service reports. We maintain credit limits for each of our customers and parental guarantees and collateral are used to manage our exposure to counterparties according to our established policy.
