Water Drive
In a porous rock, as gas is withdrawn from the reservoir, water expands into the region formerly occupied by the gas as pressure is released. This often has the result of trapping volumes of gas so that they cannot be produced, thus reducing the recovery of gas. Not a problem with a Depletion Drive Reservoir. See Aquifer.
