The Powder River Basin coalbed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up.

Gas content in the Powder River Basin is much lower than in the San Juan Basin (Table ), but the large production of gas in the Powder River Basin suggests that low gas content is compensated by large coal volumes. This also suggests that the Powder River Basin may feature a significant contribution of free (, not adsorbed) gas in its coal.
