ABSTRACT:
A process for modifying the minimum miscibility pressure (MMP) of a drive fluid and hydrocarbonaceous fluid mixture by addition of alcohol to the drive fluid. Alcohols which can be utilized include methanol through octanol. The preferred drive fluid comprises carbon dioxide. Selection of the alcohol will depend on the water saturation in the reservoir and gravity of the crude oil. MMP modification results in an increased and more efficient recovery of reservoir oil.
