Experiments were conducted in a linear sand pack to determine recoveries of a light oil and viscous oil by injection of carbon dioxide, hydrogen sulfide, and CO/sub 2/-H/sub 2/S mixtures. Experimental results indicated that the light oil was displaced miscibly when the injected fluid was in a liquid phase; miscible displacement apparently was achieved at lower pressures with hydrogen sulfide than with carbon dioxide. Miscibility was not obtained in tests conducted with the viscous oil, and recoveries of this oil prior to breakthrough were approximately equal for carbon dioxide and for hydrogen sulfide. However, hydrogen sulfide was substantially more effective than carbon dioxide in displacing the viscous oil after breakthrough of the injected fluid. 15 references.
