EVALUATION OF ENVIRONMENTAL FRIENDLY ULTRA LOW IFT SURFACTANTS FOR CHEMICAL EOR APPLICATION

Throughout the century, Oil & Gas companies have continued to harvest the raw crude oil available readily in underground reservoirs. Various methods have been utilized in the process of effectively recovering crude oil from these reservoirs, such as Enhanced Oil Recovery (EOR). One of the method...
