Abstract

A method of recovering petroleum fluids from an underground reservoir comprising the steps of: injecting into the reservoir a substantially water insoluble gas; generating and directing soundwaves into the reservoir to release petroleum fluids retained therein; and producing the released petroleum fluids through a well communicating with the reservoir. In an alternate embodiment of the invention, after sufficient water insoluble gas is injected forcing water in the reservoir downwardly and forming a water/oil/gas interface, water and/or oil soluble gas may be injected into the reservoir.
