Abstract
Recovery of oil from an oil-containing formation is effected by injection of steam followed by a soak period, if desired, and then injecting a mixture of sodium bicarbonate and citric acid that react in the formation to form carbon dioxide in situ. A driving fluid, preferably hot water or low quality steam (less than 20%), is then injected to displace the carbon dioxide and oil toward a production well for recovery. The process may be operated under conditions wherein the carbon dioxide formed in situ is miscible with the formation oil at the pressure and temperature of the formation thereby effecting miscible displacement and enhancing oil recovery.
