  • Patent number: 5711373
    Abstract: The invention disclosed herein is a method for producing oil from a reservoir after predetermining its residual oil saturation, S.sub.orm. Such a method would displace a hydrocarbon fluid in a subterranean formation using a substantially non-aqueous displacement fluid after a waterflood. The non-aqueous displacement fluid can be introduced as a single bank, in alternating sequence with water, or by other means. The method predetermines S.sub.orm using the difference in the solubility parameters between the hydrocarbon liquid in the formation and the displacement fluid to be used for displacing the hydrocarbon fluid. The solubility parameter of the hydrocarbon liquid can be determined by a variety methods including, but not limited to, (1) using the hydrocarbon liquid's energy of vaporization, .DELTA.E.sub.
