...° (intermediate wet) for PW-2. Wettability alteration was further supported by the Amott-Harvey index. At the oil-brine interface, equilibrium interfacial tension slightly increased from 8.35 mN/m 2 for PW-1 to 10.87 mN/m 2 for PW-2. However, the surface elasticity was calculated to increase from 43.3 mN/m 2...

...-water interface was destroyed due to the surface activity of silica NPs. During the core flooding experiments, NWAG injection could reduce the displacement pressure by 57.14% and increase oil recovery by 23.31% compared to WAG injection. By comparing produced-oil components after WAG and NWAG injection...

... at the liquid/liquid interface between soluble surfactant solution and crude oil, loss of surfactant to liquid/solid interfaces can create a negative effect for some of these applications in terms of performance and economics. This study; therefore, focuses on investigating the adsorption mechanism...

... stability can be attributed to the protonation of poly [2-(N, N-diethylamino) ethyl methacrylate] (PDEA) residues at low pH values. Accordingly the polymers intend to become more hydrophilic and depart from the oil-water interface, leading to an increased interfacial tension. Furthermore, it was found...
