    Enhanced oil recovery: Nanoparticles for wettability alteration and interfacial tension reduction

    Nanoparticles alone or integrated with conventional enhanced recovery processes have shown promising performance in improving oil recovery.

    Enhanced oil recovery: Why measure wettability at high pressures and temperatures?

    Studies show the influence of EOR agents on the reservoir rock wettability. Studies are not considering the reservoir conditions i.e. high pressure.

    Enhanced oil recovery: Comparison of oil reservoir wettability measurement techniques

    There are three commonly used wettability measurement techniques for oil reservoir characterization; Contact angle, Amott-Harvey, and USBM.

    Enhanced oil recovery - Smart water flooding

    Using so-called smart water flooding has increased interest in both sandstone and carbonate reservoirs due to its low cost and minimum impact on the environment.

    Enhanced oil recovery: How to measure the wettability of carbonate reservoir core?

    Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.

    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.
