FORT WORTH, TX -- (Marketwire) -- 06/22/10 -- Quicksilver Resources Inc. (NYSE: KWK) today announced the following changes to its operating management team:

Stan Page, 53, has been named Senior Vice President, U.S. Operations. Page joined Quicksilver in October 2007 as Vice President, U.S. Operations, primarily responsible for development of the company's Fort Worth Basin Barnett Shale operations in north Texas. In his new role, Page will be responsible for all U.S. operations including the company's expanding activities in the Greater Green River Basin of northern Colorado and Wyoming and the Alberta Bakken Basin in western Montana.

Joe Farley, 50, has been named Vice President, Rocky Mountain and New Ventures Operations. In this newly created role, Farley will be responsible for exploration, development and exploitation of the company's growing opportunities in the Greater Green River and Alberta Bakken basins. Farley, who joined Quicksilver in 1996, previously served as Senior Vice President and Chief Operating Officer of Quicksilver Resources Canada Inc. and will relocate to the company's Fort Worth headquarters this fall.

Dave Rushford, 50, will join Quicksilver in August as Senior Vice President and Chief Operating Officer of Quicksilver Resources Canada Inc.

Rushford will be located in the company's Calgary headquarters for Canadian operations.

'We believe that these management changes will enable Quicksilver to more efficiently explore, develop and exploit our growing portfolio of unconventional resource plays in the U.S. and Canada, while preserving our low-cost structure,' said Glenn Darden, President and Chief Executive Officer of Quicksilver Resources. 'The company has a solid base of development and exploitation projects in the Fort Worth Basin and the coals of Horseshoe Canyon in Alberta, Canada. It is management's belief that these two existing producing areas can provide double-digit production growth for the company for the next several years and ultimately more than double our existing proven reserves of 2.5 trillion cubic feet of natural gas equivalents (Tcfe).'

'Through the successful efforts of our new ventures and operating groups, the company has also amassed very meaningful acreage positions in developing plays including the Horn River Basin of northeast British Columbia, the Greater Green River Basin and the Alberta Bakken Basin. Management further believes that these new areas offer the potential to expand the company's total resource potential to greater than 15 Tcfe.'
