How to alter wettability in carbonate reservoir?

Carbonate reservoirs are characterized as intermediate to oil- wet. Altering the wettability of the carbonates has been proposed as one of the main mechanisms for enhanced oil recovery.

3 examples of how to utilize high pressure tensiometer

Different enhanced oil recovery methods are used to alter the wettability of the reservoir rock. To study the wettability alteration at the reservoir conditions, an instrument where the measurements can be done at high pressures and temperatures are needed.

Effect of solid wettability on oil displacement and liberation from host rock in water

Unconventional oils, such as heavy oil, extra heavy oil, and bitumen, normally exist tightly on host solids such as rocks, sands and clay minerals. Successful liberation of unconventional oil from solids is essential for effective recovery.

Why is wettability important in enhanced oil recovery?

In enhanced oil recovery wettability plays an important role as that determines the interactions between the solid (rock) and the liquids in the reservoirs (crude oil, brine). Wettability has been recognized as one of the key parameters controlling the remaining oil-in-place.
