FORT WORTH, TX -- (MARKET WIRE) -- 05/02/06 -- Quicksilver Resources Inc. (NYSE: KWK) today reported net income for first quarter of 2006 of $27.5 million on revenues of $99.7 million, or $0.34 per diluted share. Net income increased 156 percent in comparison to the company's first quarter of 2005 net income of $10.8 million on revenues of $55.2 million, or $0.14 per diluted share. Net cash from operating activities for the first quarter of 2006 was $63.3 million, which represents a 186 percent increase in comparison to $22.2 million for the first quarter of 2005.

Production

Total average production rose to 154 million cubic feet equivalent per day (MMcfe/d), a 15 percent increase over the prior-year period of 134 MMcfe/d. Quicksilver Resources has now recorded 12 consecutive quarters of production growth.

President and CEO, Glenn Darden, commented, "The growth of Quicksilver's production over the last three years has come entirely from the extensive inventory of projects our team has developed. This growth rate should accelerate as we increase the number of drilling rigs in our Barnett play and should be reflected in all our financial measures."

Natural gas production for the first quarter of 2006 was 12.5 billion cubic feet (Bcf), or an average of 139 million cubic feet per day (MMcf/d), as compared to production of 11.1 Bcf, or an average of 123 MMcf/d, for the same period in 2005. The price realized for the company's natural gas production in the first quarter of 2006, after adjusting for the effects of hedging, averaged $6.95 per thousand cubic feet (Mcf). This represents an increase of 61 percent over the prior-year period amount of $4.32. Natural gas, including natural gas liquids (NGL), comprised 94 percent of the company's total production in the first quarter of 2006.

Oil and condensate production for the first quarter of 2006 was 143,000 barrels, or 1,590 barrels per day, as compared to 128,000 barrels of production in the first quarter of 2005. Oil and condensate prices realized for the first quarter of 2006 averaged $58.64 per barrel compared to $46.05 per barrel for the prior year first quarter.

Natural gas liquids production for the first quarter of 2006 was 85,000 barrels compared to 32,000 barrels in the first quarter of 2005, which is an increase of 164 percent over the prior-year first quarter. The company realized an average $39.91 per barrel for natural gas liquids in the first quarter of 2006, compared to the average of $32.93 per barrel realized in the first quarter of 2005.

Operations Update

In the Barnett Shale project in the Fort Worth Basin, current net production is approximately 35 MMcfe/d with 48 wells completed and tied into sales. The company has drilled a total of 71 gross operated wells since inception of the project in 2004 and has drilled 26 gross operated wells for the current year 2006. The company currently has six rigs drilling in the Barnett Shale play, and four more rigs have been contracted to begin drilling before the fourth quarter. The company's natural gas cryogenic plant is currently processing gas, and the company expects to see an increase in its natural gas liquids production in the second quarter of 2006. The plant processes Quicksilver's Barnett gas volumes along with royalty and third-party gas on a fee basis.

In Alberta, Canada, the company has drilled 120 gross (64 net) wells year to date and has tied 98 gross wells (54 net) into sales. Current production is approximately 50 MMcf/d. Spring break-up has halted the movement of heavy equipment in the field, suspending drilling, completions and the installation of pipelines. The company expects to resume drilling in Canada with four rigs once break-up ends, which is anticipated to occur in late May with a target of 270 net wells for the year.

In Michigan, the Antrim shale horizontal re-entry program is continuing to post good results. Production increases from the first 16 wells average 120 Mcf per day per well. An additional 16 wells are planned for the remainder of the year.

Earnings per Share Calculation

The diluted net income per common share is calculated assuming conversion of the entire $150 million principal amount of our outstanding convertible debentures. For purposes of this calculation, net income is increased by $731,000 of interest expense less an income tax benefit of $256,000 and then divided by the diluted weighted average shares outstanding.

The company's conference call to discuss operational and financial results for the first quarter 2006 is scheduled for Wednesday, May 3, 2006 at 10:00 a.m. central time.

Quicksilver invites interested persons to participate in the first quarter call by dialing (877) 313-7932, ID number 4075885 prior to 9:55 a.m. A digital replay of the conference call will be available at 1:00 p.m. central time the same day, and will remain available for one week.
