AN X-RAY IMAGING AND NUMERICAL SIMULATION MODELLING OF DIFFERENT IMMISCIBLE WATER ALTERNATING GAS INJECTION SCHEMES FOR OPTIMUM DISPLACEMENT EFFICIENCY

Water Alternating Gas (WAG) injection is a well-known Enhanced Oil Recovery process to improve sweep and displacement efficiency by gas trapping and controlling the mobility of gas. The main aim of the WAG injection is to maximize the three�phase flow region in the reservoir and minimize non-swe...
