FORT WORTH, TX–( EMWNews – April 7, 2008) – Quicksilver Resources Inc. (NYSE: KWK) today

announced that it has acquired 19 licenses covering approximately 127,000

net contiguous acres in the Horn River Basin in northeast British Columbia.

The company has identified more than 500 feet of gross thickness from the

Upper Devonian Muskwa and Klua shale formations at depths ranging from

7,800 to 9,000 feet on the licenses.

“Our new ventures team in Canada has done an excellent job of applying the

company’s extensive knowledge of unconventional gas reservoirs to identify

and acquire these licenses in one of the most exciting emerging basins in

North America,” said Glenn Darden, Quicksilver president and chief

executive officer. “The Muskwa and Klua shales have the right

characteristics which we believe can provide a significant resource

opportunity for Quicksilver.”

Quicksilver acquired the licenses during Crown lease sales held in November

2007 and March 2008 at a total average cost of approximately C$655 per

acre. The company plans to drill up to four wells on this acreage during

the upcoming 2008-2009 winter drilling season.

Quicksilver’s first-quarter 2008 production volumes are now expected to

average approximately 211 MMcfe per day. Increased expected revenues, due

to higher commodity prices for natural gas and related natural gas liquids,

are expected to be partially offset by increased price-related operating

costs. As a result, unit operating costs for the first quarter of 2008 for

production, gathering and processing and transportation are now projected

in the range of $1.80 to $1.90 per Mcfe.

In Quicksilver’s first-quarter 2008 earnings, the company will include

approximately $6.2 million of pre-tax earnings from an equity affiliate.

The earnings are attributable to the company’s approximate 32% ownership in

BreitBurn Energy Partners L.P.’s (BBEP) fourth-quarter 2007 results from

the date of acquisition of the BBEP units on November 1, 2007. Quicksilver

received approximately $9.7 million of cash distributions from the BBEP

units during the first quarter of 2008.
