摘要
A process is provided for recovering liquid hydrocarbons from a subterranean hydrocarbon-bearing formation by sequential injection of a pair of immiscible gases of differing composition which displace the liquid hydrocarbons from the formation. The compositions of the displacement gases are selected such that one gas is characterized as a swelling gas and the other is characterized as a non-swelling gas with respect to the liquid hydrocarbons in place.
