Quicksilver Resources Increases 2007 Capital Budget

Increases Forecast for Texas Production

FORT WORTH, TEXAS (September 24, 2007)– Quicksilver Resources Inc. (NYSE: KWK) announced that its board of directors has unanimously approved a revised 2007 capital budget of $810 million, representing an increase of $200 million or approximately 33 percent from the initial budget of $610 million.  The company also announced that it expects reported daily production volumes for 2007 to still average nearly 210 million cubic feet of natural gas equivalents (MMcfe), despite the previously announced divestment of volumes from Michigan, Indiana and Kentucky with an assumed effective date of November 1, 2007, due to an increase in expected production volumes in Texas.

“Efficiency gains by our operating team in the Fort Worth Basin have enabled Quicksilver to expand the Barnett Shale drilling program to more than 200 wells this year without increasing our 14-rig utilization,” said Glenn Darden, Quicksilver president and chief executive officer.  “As a result of this increased drilling activity, we anticipate production volumes in Texas to increase at a greater rate than previously projected.”

The $200 million increase in the 2007 capital budget includes approximately $150 million for drilling, approximately $40 million for leasehold acquisitions, approximately $5 million for gathering and processing facilities and approximately $5 million for corporate expenditures.  Nearly all of the budget increase is expected for activities in the Fort Worth Basin.

Update on BreitBurn Transaction

Quicksilver has determined that the previously announced transaction to contribute all of its properties and facilities in Michigan, Indiana and Kentucky to BreitBurn Operating L.P. will be treated as continuing operations for financial reporting purposes.  The transaction will be effective at closing, which is expected to occur by November 1, 2007.

Production Guidance

As a result of the increased drilling activity coupled with the revised accounting treatment for the BreitBurn transaction, Quicksilver updated its expectations for reported production volumes for the remainder of 2007.  Third-quarter production volumes are projected to average in the range of 220 MMcfe to 230 MMcfe per day.  Fourth-quarter volumes are projected to average in the range of 195 MMcfe to 205 MMcfe per day, reflecting the divestment of approximately 75 MMcfe per day of volumes from Michigan, Indiana and Kentucky with an assumed effective date of November 1, 2007, partially offset by increasing volumes from the Fort Worth Basin.
