Miscible CO2 flooding has been used as an EOR method for carbonate reservoirs which
hold around 60% of the world's oil reserves. However, natural fractures, unfavorable mobility …

Based on practical needs of oil fields, the viscosity, interfacial tension, static absorption,
phase behaviors, molecular clew dimension (D h), molecular configuration and flooding …

The ability of a novel nonionic CO 2-soluble surfactant to propagate foam in porous media
was compared with that of a conventional anionic surfactant (aqueous soluble only) through …

CO 2 enhanced oil recovery by using newly synthesized CO 2 philic surfactant as CO 2
mobility control agent is reported. Nonyl phenol ethoxylate sulphonate (NPES) was …

Abstract Supercritical CO 2 (ScCO 2) foam could benefit both industry revenue generation
through EOR and climate control with CO 2 storage/utilization. Relative to aqueous soluble …

Gas hydrate-based technology is a promising method for solidifying and sequestrating of
CO2 gas into stratum sediments to reduce anthropogenic CO2 emissions and realize the …

The ability of surfactants to interact with CO 2 is essential if the CO 2 foam is intended to
augment a water flooding process as a method to displace oil from a reservoir. Apart from …

Experimental studies have showed that CO 2 soluble surfactants were more effective than
aqueous soluble surfactant as supercritical CO 2 foaming agent in fractured carbonate …

The application of CO2 injection for mobilization of trapped oil in porous media is the most
frequently applied method for EOR projects. Despite of the fact that the CO2 injection can …

The foam plays an important role in EOR application, while crude oil properties significantly
affect foam behavior. In this study we compare the performance of foam generated by two …
