Abstract
Cold Heavy Oil Production (CHOP) involves encouragement and maintenance of sand influx as a deliberate production enhancement method in heavy oil solution gas drive reservoirs with no bottom water drive. In site foamy oil generation and flow help maintain sand flux, giving continuons stimulation and permeability enhancement. Also, generation of a continuous gas phase in heavy oil is greatly retarded, compared to conventional oil, thus preserving reservoir energy.
