Carbone dioxide flooding has been applied worldwide as a successful enhanced oil recovery. Carbone dioxide flooding may be applied as a continuous injection or as water alternating gas (WAG) process. Optimization of the injection mode of carbon dioxide is important for economical field application. This paper focuses on using a fully compositional simulation model for “AEB-3C” sandstone oil reservoir; in one of the Western Desert oil fields in Egypt; to predict the impact of CO2 miscible flooding on the reservoir oil recovery and net present value (NPV), to define the best mode of operation that is straight CO2 injection or water alternating gas (WAG) processes and to show the difference between pure and impure CO2. Moreover, several sensitivity runs were done on the oil price to show minimum profitable value of oil price when applying such a tertiary method in the subject field.
