ABSTRACT:
This invention relates to an improved method for recovering oil from a subterranean formation comprising sequentially injecting into the formation through an injection well in communication therewith: (a) a slug of an aqueous solution containing a high concentration of a gas mobility control agent; (b) a slug of an aqueous solution containing a low concentration of said gas mobility control agent; and (c) gas as the primary oil displacing fluid selected from the group consisting of carbon dioxide, hydrocarbon gas, inert gas and steam whereby said gas and said slugs of aqueous solution containing the gas mobility control agent form a mixture in the formation that significantly reduces gas mobility in the more permeable regions of the formation.
