Wettability has a strong influence on multi-phase flow behavior through reservoir rock. Reservoir rocks tend to have spatially varying wettability. Prior contact with oil, are almost always naturally water-wet. As oil invades the pore-space over geologic time, initial water-wet state may be altered in certain locations due adhesion of substances within phase grains. Mechanisms wettability alter...

Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. Fractured reservoirs with high matrix porosity and low matrix permeability need a seconda...

Wettability alteration that occurs as a result of changing the brine composition or using chemicals lower interfacial tension can significantly alter mobility nonaqueous liquid (NAPL)/water phases. Here, we show including dynamic wettability alternation (moving from non-water-wet to water-wet) interpolating between two sets relative permeability curves may create an unstable displacement reside...

Wettability is a key parameter for optimizing the residual oil recovery from geological rock formations and it provides path improved geo-storage of energy. Thus, motive behind wettability alteration hydrophobic to hydrophilic enhance productivity. this work concentrates on Sui main limestone reservoir core samples’ (altering their surface wetting behavior an oil-wet water-wet state) enhanced r...
