Calfrac Announces Increase to 2010 Capital Program

CALGARY, June 7 /CNW/ - Calfrac Well Services Ltd. ("Calfrac") (TSX-CFW) is pleased to announce a $60 million increase to its 2010 capital program for a revised total of $176 million, including carryforward capital from 2009. The increase is largely focused on the construction of a large fracturing spread for Calfrac's U.S. operations, supported by a recently executed long-term minimum commitment contract with a large customer relating to the Marcellus Shale Basin. Delivery of the spread is expected late in the fourth quarter of 2010. The incremental capital will add an additional 55,000 horsepower to Calfrac's fracturing fleet, bringing its total horsepower capacity to approximately 585,000 HHP at the culmination of the 2010 capital program. The balance of the increase in capital is to further bolster Calfrac's infrastructure as it continues to gain a larger presence in the Marcellus shale play in the U.S. and the unconventional plays in northern Alberta and northeast British Columbia in Canada. It is expected that approximately $25 million of the 2010 capital program will be expended in 2011. The increased capital will be funded from cash flow and existing credit facilities.

Calfrac's common shares are publicly traded on the Toronto Stock Exchange under the trading symbol "CFW". Calfrac provides specialized oilfield services to exploration and production companies designed to increase the production of hydrocarbons from wells drilled throughout western Canada, the United States, Russia, Mexico and Argentina.
