INVESTIGATION OF THE EFFECTS OF USING CHEMICALLY ENHANCED WATER DURING WATER ALTERNATING GAS INJECTION ON OIL RECOVERY

The field incremental recovery of immiscible water alternating gas (WAG) process is about 5-l 0% original oil in place (OOIP). A low recovery of the WAG process is associated with water blocking, gravity segregation, unfavorable mobility control, and decreased gas injectivity. To minimize the...

To minimize the aforementioned problems a new EOR technique, named as chemically enhanced water alternating gas (CW AG), which significantly improves the performance of the WAG process, is proposed. The CW AG process uses alkaline, surfactant, and polymer as a chemical slug which is injected during WAG process to reduce the interfacial tension (IFT) and improve the mobility ratio, simultaneously.
