About Wyoming Oil & Gas and CoalBed Methane (CBM)

In 2002, Wyoming ranked second in the U.S. in proved reserves of natural gas and seventh in proved reserves of crude oil. Collectively over 26,000 wells produced 54.7 million barrels of oil and 1.75 trillion cubic feet of natural gas. Proved reserves of natural gas were at an all-time high of 18.4 trillion cubic feet, while proved reserves of crude oil were 489 million barrels.

Reserves of CBM in the Powder River Basin are estimated at 31.8 trillion cubic feet. Nearly 100 wells are being drilled each week, and the gas companies say the entire 8-million-acre basin could have 50,000 to 100,000 producing wells before they are finished. This is the largest onshore natural gas play in North America within the last ten years.
