The impact of the electrical behavior of oil-brine-rock interfaces on the ionic transport rate in a thin film, hydrodynamic pressure, and low salinity waterflooding effect
Wettability alteration is the principal low-salinity-effect (LSE) in many oil-brine-rock (OBR)
systems. Our recent experimental results have demonstrated that wettability alteration by low …
