Performance of low-salinity water flooding for enhanced oil recovery improved by SiO2 nanoparticles

Abstract Low-salinity water injection has been utilized as a promising method for oil recovery in recent years. Low-salinity water flooding changes the ion composition or brine salinity for improving oil recovery. Recently, the application of nanoparticles with low-salinity water flooding has shown...
