"ABSTRACT OF THE DISCLOSURE" An enhanced oil recovery process employing an aqueous alkyl polyethylene oxide sulfate solution and a carbon dioxide displacement fluid at injection pressures above about 1,500 p.s.i. and significantly above the miscible-displacement pressure. The aqueous solution of an alkyl polyethylene oxide sulfate having 8 or 9 carbon atoms in the alkyl group and between 1 and 5 ethoxy groups significantly improves the areal sweep and overall efficiencies of dense fluid carbon dioxide enhanced oil recovery processes, especially under high salinity and low pH conditions. The efficiency of the process is increased as the injection pressure is increased.
