Abstract
A process for the enhanced recovery of liquid hydrocarbons from a subterranean hydrocarbon-bearing formation wherein natural gas which is immiscible with the liquid hydrocarbons is injected into the formation via a well. The well is shut in for a period of time to permit the natural gas to render the liquid hydrocarbons mobile and thereafter the mobilized liquid hydrocarbons are produced from the well.
