• Coal is a source rock, seal, as

well as a reservoir rock

• Gas is adsorbed on the coal

surface with little free gas

• Gas is released by lowering the

pressure through dewatering

• Gas is delivered through a fracture

network known as the cleat system

• CBM projects typically have long

life > 3 years
