Trona workers and hunters from the USWA Union Locals 13214 and 15320 conducted over-flights of coalbed methane fields in the Powder River Basin in northeast Wyoming and met with residents and ranchers impacted by CBM development. The Powder River Basin contains about 14,000 CBM wells and federal estimates show that figure could rise to 50,000 CBM wells or more by the year 2010. Pennie Vance of the Powder River Resource Basin Council noted the coalbed methane boom in northeast Wyoming is expected to bring over 17,000 miles of new roads, 20,000 miles of new pipelines and the disposal of over 1.4 trillion gallons of water. "It is tremendously heartening to see the level of concern citizens have ... however, if what's happening in the Powder River Basin today is a preview of things to come in southwestern Wyoming, citizens should be very, very concerned," Vance said. Southwest Wyoming, including the Upper Green River Valley and the Red Desert, contains coalbed methane reserves that have been estimated at 314 trillion cubic feet. Alliance members said the region's CBM reserves contains an estimated 12 times as much as the Powder River Basin's reserves. Dru Bower, vice president of the Petroleum Association of Wyoming, said the coalbed methane boom, if it comes to southwest Wyoming, will be different than the CBM boom in northeast Wyoming. She said in southwest Wyoming, CBM development is expected to be much slower,much deeper and very different than the Powder River Basin. One big difference will be the method of water disposal. Coalbed methane is produced when water is pumped out of a coal seam, releasing the gas that is trapped inside. Unlike northeast Wyoming -- where water discharge is dumped on the surface -- companies is southwest Wyoming most likely would be required to inject the water into the ground or use other discharge methods. "Companies are working on new technologies for treatment of water ... so it can be discharged for beneficial uses," she said. Previous Next
