Surfactants have ability to mobilize the residual oil trapped in porous medium and resulting
higher oil recovery by altering interfacial tension between residual oil and water. However …

Surfactants have ability to reduce the interfacial tension between residual oil and water and
give high recovery factor. Adsorption of surfactant onto the solid surface makes it less …

Around 40% of the current world conventional oil production comes from carbonate
reservoirs, dominantly mature and declining giant oilfields. Tertiary oil production methods …

The adsorption of surfactants on reservoir rock has been known from early studies on
surfactant flooding for this purpose, Adsorption mechanism of new nonionic surfactant on …

The adsorption behaviour of aqueous solutions of anionic surfactant and polymeric
surfactant derived from Jatropha oil onto sand surface was investigated in connection of …

Anionic surfactants are widely used as an effective chemical for enhanced oil recovery
because of their unique characteristics of reducing interfacial tension (IFT) between the …

Owing to the problems associated with clay swelling, the implementation of surfactant
flooding, a well-advised chemical enhanced oil recovery (EOR) technique for sandstone …

Surfactant flooding aims at lowering the interfacial tensions between the oil and water
phases to improve the displacement efficiency during oil recovery. However, surfactant …

Minimizing the loss of chemicals due to adsorption unto the rock materials during injection
into petroleum reservoirs is critical to improve the economics and environmental footprint of …

Surfactant flooding improves oil recovery by lowering the interfacial tension and/or altering
the reservoir rock's wettability. However, surfactant losses caused by adsorption on the …
