Abstract
In a CO.sub.2 miscible displacement enhanced oil recovery process, produced CO.sub.2 -hydrocarbon gas containing from more than the maximum CO.sub.2 content tolerable in a fuel gas up to about 70 volume percent CO.sub.2 is reinjected into a small portion of the well pattern volume and produced CO.sub.2 -hydrocarbon gas containing more than 70 volume percent CO.sub.2 is reinjected into a larger portion of the well pattern volume. The method provides a more effective utilization of CO.sub.2 in a CO.sub.2 miscible enhanced oil recovery process while maintaining most of the oil-containing formation under miscible conditions.
