Abstract
A method for mitigating gas override in an hydrocarbon reservoir by increasing sweep efficiency and consequently improving incremental oil recovery is provided with at least one injection well, at least one production well, and an hydrocarbon reservoir. The injection well and the production well are in fluid communication with the hydrocarbon reservoir. An injection blend produced by mixing a displacement fluid with an organic solvent is transferred into the hydrocarbon reservoir through the injection well. Preferably, the displacement fluid is supercritical carbon dioxide and the organic solvent is triethyl citrate. The higher density and the viscosity of the injection blend are vital in reducing gravity override and improving sweep efficiency. A resulting injection blend is extracted from the production well and the organic solvent is separated. Since the organic solvent can be reused, the method of mitigating gas override can be financially and operationally beneficial.
