Silica nanofluids in polyacrylamide with and without surfactant: Viscosity, surface tension, and interfacial tension with liquid paraffin. Journal of Petroleum Science and Engineering 2017, 152, 575-585. DOI: 10.1016/j.petrol.2017.01.039.
Oil production from matured crude oil reservoirs is still associated with low recovery factors. Chemical enhanced oil recovery (EOR) is one of the techniques which can significantly improve the recovery factor of the trapped oil. This is mainly achieved by lowering the interfacial tension (IFT) of the crude oil–brine/aqueous chemical and increasing the viscosity of the injected fluid.
