Nanoemulsions are kinetically stable homogeneous dispersions of immiscible liquids with
droplet sizes in the order of 500 nm. The nano-size droplets are advantageous in enhancing …

The relatively low density and viscosity of carbon dioxide (CO 2) in supercritical state create
several drawbacks, including gravity override, viscous fingering, water production/treatment …

Surfactant injection into a depleted hydrocarbon reservoir is one of the ways to reduce
residual oil saturation, thereby enhancing crude oil production. However, surfactants …

Surfactants are known as interfacial tension (IFT) reducer additives in enhanced oil recovery
(EOR) process. The use of chemical surfactants has always been a challenge due to the …

Abstract Among the Enhanced Oil Recovery (EOR) methods, gas-based EOR methods are
very popular all over the world. The gas injection has a high ability to increase microscopic …

Injecting surfactant by means of chemical enhanced oil recovery (cEOR) has acquired
predominant attention in improving oil recovery by changing either fluid/rock and/or …

Interfacial tension (IFT) reduction and wettability alteration (WA) are important enhanced oil
recovery (EOR) mechanisms that help displace residual oil from the reservoir. Many studies …

The design and development of chemical routes with fascinating physicochemical attributes
comprise a major field of research in enhanced oil recovery (EOR).'Dimerization'depicts a …

Gas channeling easily occurs in CO 2 flooding, leading to lower oil production efficiency. CO
2 oil-based foam can effectively control gas channeling, so it is particularly important to study …

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 …
