|Formation Details||The Powder River Basin is the fastest growing CBM play in the United States. The vast coal deposits of Wyoming contain massive quantities of methane gas and the Powder River Basin is one of the thickest accumulations of coal in the world.|
|Notes||Powder River Basin coal ranges from 200 to 2,500
feet below the surface, and most CBM drilling is at the
200–1,200 foot range. Wells typically take from three to six days to complete.Coals in the Powder River Basin are very permeable, shallow, and thick, and the low gas content and low pressure were initially seen as barriers to development.
