ABSTRACT:
A process for recovering oil from a subterranean hydrocarbon-bearing reservoir having a hydrocarbon and penetrated by a wellbore. The process comprises injecting through the wellbore and into the subterranean hydrocarbon-bearing reservoir an emulsifying composition containing an aqueous phase and a minor amount of an emulsifying agent such that the emulsifying composition contacts at least a portion of the hydrocarbon to form an oil-in-aqueous phase emulsion within the subterranean hydrocarbon-bearing reservoir.
