In this paper, CO2 injection for enhancing oil recovery assisted by gravity drainage using reservoir simulation (using CMG’s IMEX and GEM simulators) for a miscible and immiscible process is studied. The reservoir pressure declines with time and reaches a point where the fluids from the reservoir will not flow into the wellbore. Then the reservoir is assisted by additional pressure support under secondary recovery methods by gas injection or water flooding. For the conditions where the reservoir is having immobile oil due to relation of fluid and rock properties enhanced oil recovery techniques are adopted. CO2 is used under gas injection techniques is one of the most efficient and economic method to recover the oil. The gravity drainage process of CO2 when injected into the reservoir is observed in this paper. To understand and analyze the process of gravity drainage under miscible and immiscible CO2 injection a 50oAPI gravity oil was selected to study under simulation model of selected grid size. The analysis was made for seven different cases and their relations with time, production of water and GOR are represented.
