Simulation Study for Potential Identification of Light Oil Air Injection in Malaysian Reservoirs

Malaysian forecast of oil production is expected to decline from 2007 and projections of domestic consumption indicate that the country might become a net oil importer by the end of this decade. Nevertheless, some of the existing reservoirs still contain large volumes of oil, which has not been ef...
