Abstract

A method is disclosed of displacing reservoir fluids through a subterranean retrograde or gas-condensate reservoir wherein a displacement fluid is introduced into the reservoir and it is displaced along with the reservoir fluids through the reservoir. The displacement fluid can be inherently miscible with the reservoir fluids at the temperture and pressure of the reservoir and comprises a nonoxidizing gas selected from a group consisting of carbon dioxide, flue gas, nitrogen, residue gas, and mixtures thereof in selected proportions.
