Abstract

In oil recovery technique using SiO2 nanoparticles, evaluating the transportability of the nanoparticles in various sandstones contributes to controls of fluid behaviour in petroleum reservoirs and improvement of oil recovery factor. In the core flooding test with high-content kaolinite sandstones, the maximum oil recovery of about 4.5% was obtained by injecting negatively surface charged nanoparticles without adsorption of a large amount of the SiO2 nanoparticles on the rocks and the pore channels plugging effect. The main mechanisms of the oil recovery were suggested wettability alteration changing to more water-wet on the rock surface and increase of disjoining pressure.
