                Quicksilver Resources Provides Operations Update

FORT WORTH,  TEXAS (October 3, 2003) - Quicksilver  Resources Inc.  (NYSE:  KWK)
today is providing the following  operations update with production and earnings
guidance.

Canadian Coal Bed Methane

Quicksilver,  through its Canadian  subsidiary,  MGV Energy,  completed both its
Beiseker and Gayford gas plants in August and  September,  and the company is on
target to exceed its goal of 15 million  cubic  feet per day  (Mmcf/d)  year-end
2003 exit rate.  One  hundred  and  twenty-six  gross  wells  have been  drilled
year-to-date  with at least 50 more  wells to be drilled by the end of the year.
The company is continuing  exploration and  development  operations in six joint
venture areas. Quicksilver is now producing coal bed methane into sales lines as
far north as 120 miles from the Beiseker and Gayford development areas.

Indiana/Kentucky New Albany Shale

The  company's  Cardinal  Pipeline,  which  connects  Quicksilver's  Indiana and
Kentucky  New  Albany  shale  production  into an  interstate  pipeline,  is now
operational.  The company is on track to hit its year-end  2003 target exit rate
of 10 to 12 Mmcf/d. The completion of the Cardinal Pipeline,  with a capacity of
100 million  cubic feet per day,  opens the  southern  Indiana and  Northwestern
Kentucky area to an expanded gas market for  Quicksilver.  To date in 2003,  the
company has drilled 75 of a planned 85 wells in this area, with  completions and
tie-ins to continue for the remainder of the year.

Michigan Antrim Shale

In the Antrim shale,  the  company's  largest  producing  area,  Quicksilver  is
experiencing  third-party  gas plant  outages that began in August.  The current
estimate is that the previously  provided total company  production  guidance of
108 Mmcf/d for the third quarter will fall short by  approximately  2 Mmcf/d due
to these plant outages. In spite of the production  shortfall,  the company does
not  expect  its third  quarter  earnings  to be  significantly  different  from
previous estimates. The plant operator, CMS Gas Transmission, estimates that the
plants will be at full capacity by October 10, 2003.  Quicksilver has drilled 39
net wells in the Antrim shale in 2003 and plans to drill an  additional  13 to15
net wells by year-end.

Fourth Quarter Guidance

The company is updating guidance for the fourth quarter.  Total daily production
is expected to average between 121 to 123 Mmcf/d and the company's year-end exit
rate is anticipated to be in the range of 125 to 130 Mmcf/d.  All other guidance
factors remain unchanged at this time.
