Compton reports 20% increase in reserves

CALGARY, March 11 /CNW/ - Compton Petroleum Corporation (TSX - CMT, NYSE - CMZ) is pleased to announce reserves for the year ended December 31, 2006.

During 2006 Compton achieved solid reserve additions, primarily through the drill bit, at highly competitive finding and development costs. The Company successfully completed its 342 well drilling program, replacing 348% of its 2006 production at an all-in Finding, Development, and Acquisition cost ("FD&A") of $8.84/boe, excluding change in future capital, and $13.56/boe, including change in future capital.

Ernie Sapieha, Compton's President and Chief Executive Officer, commented, "Our 2006 reserve additions of 42 MMboe, after production, represent an increase to 1.93 boe of reserves per common share outstanding from 1.65 boe per share in 2005. Over the last ten years, Compton has delivered a compound annual growth rate of 35% on our reserves at consistently low FD&A costs, without ever having had a material negative reserve revision. During this period, we've grown from a high risk, pure exploration company to a strong intermediate producer with low risk, high quality development assets ready for a large scale, accelerated drilling program."
