Wettability Alteration of Carbonate Rock by Chelating Agents and Viscoelastic Surfactants: Synergetic Impact

Energy & Fuels, 2022
The two most important EOR mechanisms for oil-wet carbonate rock are IFT reduction and wettability alteration. By altering rock surface wettability, the resulting positive capillary pressure can help imbibe water and displace oil from the rock matrix ...

The effect of surfactant concentration on nanoparticles surface wettability during wettability alteration of oil-wet carbonate rock

Journal of Mechanical Engineering and Sciences, 2021
Previous studies reported that the presence of surfactant increases nanoparticles surface wettability by in-situ surface activation. On the other hand, the excess of surfactant concentration has an inverse effect on particle hydrophobicity by altering it
