Nowadays, Enhanced Oil Recovery (EOR), to recover more oil from existing oil reservoirs, is an important issue. A decrease in oil recovery is caused by interfacial phenomena between oil in the reservoir and fluid injected to the reservoir to displace the oil. In the present study, we try to create oil-water reactive rheological interface which enables dramatic EOR by using changes in interfacial tension and interfacial rheology induced by chemical reaction at immiscible interface between the oil and the injected aqueous solution.
