An investigation into surfactant flooding and alkaline-surfactant-polymer flooding for enhancing oil recovery from carbonate reservoirs: Experimental study and simulation

ABSTRACT The main aim of the present work was to study history matching of surfactant flooding using CMG-STARS simulator and experimental results. In the experimental case, the critical micellar concentration of dodecyltrimethylammonium bromide solution is obtained, and the changes in the contact angle are investigated from 1 to 10% weight. Then, after water flooding, surfactant flooding is applied on the critical micellar concentration of dodecyltrimethylammonium bromide. In the simulation case, after history matching of production data, the performance of alkaline-surfactant-polymer flooding using sodium hydroxide, hydrolyzed polyacrylamide, and that surfactant was a prediction. The numerical simulation alkaline-surfactant-polymer flooding increased the oil recovery factor 26% more than surfactant flooding.
