| Summary: | Carbon dioxide (CO2) injection has been known as one of the most appealing approaches to enhance oil recovery particularly for light oil reservoirs in both secondary and tertiary recovery sequence. It is proposed that injected CO2 dissolves in to smaller adjacent droplets of oil, then swell and coalesce and extracting light hydrocarbons from the oil. The degree of swelling depends on the pressure, temperature and oil composition. CO2 can enhance oil production by reducing viscosity, reduction in interfacial tension and creating miscibility. Previous investigations regarding CO2 flooding demonstrate that, there is lack of study about the influences of low temperatures of CO2 injection (60-85 °F) on the total oil production, gas Oil ratio and oil production rate in light oil and high temperature reservoirs. Unidentified the change of total oil production with usage of liquid CO2, made us motivated to study this simulation through thermal Compositional modeling by using ECLIPSE300. |
