Development of Green Surfactants System for Wettability Alteration for Enhanced Oil Recovery (EOR) Application

The study of Chemical Enhanced Oil Recovery (EOR) has started since early 1980’s with the similar goal to improve the oil recovery. Recently, chemical injection has become attention in EOR process. The drawback of chemical surfactants technology in the EOR is the high cost and environmental issues. Since there are many gaps to be closed, the research to synthesis surfactants still going on until now. The difference of EOR from the previous recovery techniques is the injection of fluids must be able to reduce the Interfacial Tension (IFT) of the displacing oil and fluid, reducing capillary force and oil viscosity and many more criteria. The main focus of this project is to test Betaine development as green surfactants. The expected results are Betaine could help in reducing the contact angle, IFT value and has high solubility with carbon dioxide, which shows the wettability alteration in reservoir
