Abstract
Performance of CO2 and hydrocarbon (HC) gas injection into a heavy crude oil was investigated at high pressure/temperature condition, using high permeable well-sorted original reservoir sandstone. Complete series of PVT and slime tube tests were followed by vertical and horizontal gas floods to study the impact of injection rate, injectant type and reservoir pressure. Dimensional analysis was performed to study the involved mechanism and forces. Sometimes direct injection of CO2 may not be practically and economically possible. In addition, in plans for CO2 storage, CO2 as a free phase in a reservoir is coupled with a significant leakage risk that prevents the scenario of direct injection. Therefore, in the second part, the enhancement of heavy oil recovery was tested by the carbonated water injection.
