The efficiency of water and of nitrogen as CO/sub 2/ slug propellants during CO/sub 2/ flooding were studied at pressures just above the CO/sub 2/ - crude oil miscibility pressure of some oils. Two crude oils of 34/sup 0/ and 44/sup 0/ API gravity, a 2 in. X 2 in. 15 foot long and a 5 foot long horizontal consolidated sandstone cores were used for the investigation. Water was found to be more efficient than nitrogen as the CO/sub 2/ slug propellant in the range of miscibility pressures studied. The efficiency of nitrogen as a CO/sub 2/ slug propellant was found to be dependent on the flooding pressure, it increased with the flooding pressure.
