Carbon dioxide-enhanced oil recovery (CO 2-EOR) has gained widespread attention in light
of the declining conventional oil reserves. Moreover, CO 2-EOR contributes to the reduction …

Abstract In Chemical Enhanced Oil Recovery (CEOR), various chemicals such as polymer,
surfactant, alkaline, and nanoparticles are injected solely or in combination to mobilize the …

Anionic surfactants are very effective for application in enhanced oil recovery (EOR) in
sandstone reservoirs because of their promising surface-active properties. Considering the …

Foam generation technique has been practically applied to overcome gas mobility issue
during enhanced oil recovery (EOR) processes. Incorporated with the utilized gas, the …

Strong foam can be generated in porous media containing oil, resulting in incremental oil
recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam …

Gel systems are widely used as plugging materials in the oil and gas industry. Gas
channeling can be mitigated by reducing the heterogeneity of the formation and the mobility …

CO2-enhanced oil recovery (CO2-EOR) is a crucial method for CO2 utilization and
sequestration, representing an important zero-carbon or even negative-carbon emission …

Alkyl-carboxylate extended surfactants as foaming agents have been formulated to generate
stable nanoparticle-surfactant foam systems. Because of their unique characteristics, these …

The volumetric sweep efficiencies of CO 2 flooding for enhanced oil recovery (EOR) are
generally low due to problems of viscous fingering and gravity override. This paper attempts …

Study of foam stability in the presence of oil components is mainly devoted to the impacts of
aliphatic components like short-and long-chained alkanes. In this study, several …
