BR currently operates four wells producing from the deepMadison formation, each capable of gross production in excess of 50MMcf/d. Current gross production is approximately 130 MMcf/d fromthe Madison formation, but production is constrained by processingcapacity at the Lost Cabin Gas Plant in Lysite, WY. The plant’sthird train, now under construction, is scheduled for completion inlate 2002, which will allow gross production to increase to a totalof 310 MMcf/d.

Apache Corp. announced a Canadian gas discovery that tested at31 MMcf/d British Columbia on acreage acquired from Shell Canadalate last year. “Proved reserves acquired in the Shell Canadatransaction were mainly oil, but the major upside lies in gasexploration on nearly 300,000 net acres and in the staff of highlymotivated technical people who joined Apache,” said ApachePresident G. Steven Farris. Apache holds a 37% working interest inthe Ladyfern area producer. Murphy Oil, the operator, holds 33% andBeau Canada Exploration has the remaining 30% working interest.”Pressure build-up tests are under way to help in determining theapproximate size of this discovery, but it’s safe to say it has thepotential to be a very large gas field,” Farris said. Apache andits partners have under lease more than 25,000 acres in theLadyfern area and are presently drilling two additional wildcatwells on separate structures. Apache and partners will build aneight-inch-diameter pipeline 15 miles to the Beau Canada pipelineto take Ladyfern gas to Apache’s Hamburg gas plant.
