Where is coal bed natural gas produced?
According to the Energy Information Agency, 13% of the land in the lower 48 United States has some coal under it, and some of this coal contains natural gas – either in the form we know as traditional natural gas or as CBNG. According to the United States Geological Survey, the Rocky Mountain Region has extensive coal deposits bearing an estimated 30-58 trillion cubic feet (TCF) of recoverable CBNG. While impressive, this represents only one third of the total 184 TCF of natural gas in the Rocky Mountain region (Decker, 2001). Within the Rocky Mountain Region, untapped sources of CBNG exist in the Powder River Basin of Wyoming and Montana, the Greater Green River Basin of Wyoming, Colorado, and Utah, the Uinta-Piceance Basin of Colorado and Utah, and the Raton and San Juan Basins of Colorado and New Mexico. An estimated 24 TCF of recoverable CBNG resources may lie below the Powder River basin of Montana and Wyoming (Decker, 2001).
