Novel wettability modifier for waterflooding in carbonate reservoirs
Problem statementThe efficiency of waterflooding depends significantly on the rock wettability in fractured carbonate reservoirs, which often are mixed- or oil-wet. The rock wettability is determined by the interactions among crude oil, brine, and rock minerals. The current technologies for wettability alteration in carbonate rocks, such as surfactant...
