Abstract
An enhanced oil recovery process in which carbon dioxide is injected into the oil-bearing formation under supercritical conditions to act as a solvent for the oil. Mobility of the carbon dioxide is controlled by the use of a dissolved polymer whose solubility is enhanced by the use of an entrainer comprising a polar organic compound such as an alcohol or a glycol.
