Utilizing the Effect of Nitrogen to Implement Light Oil Air Injection in Malaysian Oil Fields

Air injection has been used as one of the enhanced oil recovery (EOR) techniques especially to extract the heavy oil. Nevertheless, a number of applications of in-situ combustion (ISC) for light oil reservoirs have been also reported successful. In light oil reservoirs, the thermal method of EOR is...
