2009-2-1 This storage mechanism occurs naturally and is well documented, suggesting that a gas, particularly CO 2 , can be reliably stored in coal seams. The opportunity looks even more attractive because of the possibility of simult aneous methane production.

The PCOR Partnership region has extensive reserves for both EOR and ECBM recovery. A substantial part o f the coal reserves are deep lignite seams concentrated mainly in the North Dakota portion of the Williston Basin.
