F-0938 A METHOD OF IMPROVED OIL RECOVERY BY SIMULTANEOUS INJECTION OF WATER WITH AN IN-SITU COMBUSTION PROCESS ABSTRACT In a method of recovering heavy oil from a subterranean, permeable, heavy oil-bearing reservoir, an oxygen-containing gas is injected into the lower portion of the reservoir to establish an in-situ combustion reaction therein and to form a combustion front near the injection well. Injection of the oxygen-containing gas is continued to advance the combustion front that heats the oil and generates gas to displace the oil through the reservoir towards a producing well. Water is injected into the upper portion of the reservoir during combustion to prevent gases from migrating into the upper portion of the reservoir, scavenge heat from the combustion-heated portion of the reservoir, and displace oil from the reservoir, particularly the lower region, towards the production well. The areal sweep efficiency of the injected water may be improved by the addition of thickening agents and water-soluble polymers.
