Abstract:The biggest challenges for E&P activities are the high viscosity of the oil, the geology of the formation, the high interfacial tensions (IFT) between fluids and the reservoir wetting conditions. Enhanced Oil Recovery (EOR) methods are applied to modify fluid-fluid and fluid-rock interactions in the reservoir, facilitating the oil displacement and, consequently, increasing the recovery factor. In this work, the use of silica nanofluids, with and without amphoteric surfactant, as EOR method to reduce the IFT an… Show more
