Enhanced Gas Recovery From

Kentucky Coal Beds

Kentucky coal adsorption ~ 2 CO2 : 1 CH4

Tasks -

Identification of CBM target beds.

Identification of areas with cumulative coal

thickness and lateral extent.

Identification of fault zones and mined out

areas.

Paucity of CBM data – no EGR data.
