| titleOfInvention | Recovery of oil using microemulsions |
| abstract | ABSTRACT OF THE DISCLOSURE Crude oil is a subterranean formation is recovered through the in-jection of at least one phase formed from a composition within the multi-phase region of an oil-water-surfactant ternary diagram. One embodiment includes the injection of two or more mutually immiscible phases which would be in phase equilibrium within the multiphase region in the ternary diagram of a microemulsion system, at least one of the phases being a microemulsion. Low interfacial tensions exist between the immiscible phases in equilibrium. Where one of the phases in equilibrium comprises predominantly oil or pre-dominantly water, in a further embodiment the microemulsion phase in equi-librium therewith can be injected alone to achieve efficient crude oil re-covery. Where there are three phases in equilibrium, one of which comprises predominantly oil and another comprises predominantly water, in a further embodiment the remaining microemulsion phase in equilibrium therewith can be injected alone to achieve efficient crude oil recovery. |
