RETAINING COALBED METHANE WATER DISCHARGE PERMITS

摘要

In 2002 Northwestern Energy permitted the Brennan Street Project, a coalbed methane field in the Clear Creek drainage of the Powder River basin of Wyoming. The field is located in sections 11, 13, 14, and 15 of township 53N and range 80W. It is comprised of 44 wells in total. All wells were completed by perforating through casing. About half of the wells were completed in the Lower Cook seam ranging from 2,100 to 2,400 fbs and the other half in the Smith/Anderson seam ranging in depth from 850 to 1,200 fbs. In 2005, ownership of the field passed to Wolverine and then to Brennan.
