Slim tube displacement tests on a Pembina Cardium stock-tank oil using carbon dioxide, sulfur dioxide, and four CO/sub 2//SO/sub 2/ mixtures as the flooding agents demonstrated that the mixtures have lower minimum miscibility pressures than both pure components. More oil was recovered from Berea sandstone cores when CO/sub 2/ and a CO/sub 2//SO/sub 2/ mixture were the flooding agents than when SO/sub 2/ was used. CO/sub 2/ and the CO/sub 2//SO/sub 2/ mixture recovered comparable quantities of oil from Indiana limestone, while a severe loss of permeability was observed in the corresponding SO/sub 2/ flood.
