The increasing demand for fossil fuels and the depleting of light crude oil in the next years
generates the need to exploit heavy and unconventional crude oils. To face this challenge …

Undesirable gas channeling always occurs along the high-permeability layers in
heterogeneous oil reservoirs during water-alternating-CO 2 (WAG) flooding, and …

Chemical profile control agents are the key for conducting effective reservoir control to
enhance crude oil recovery. Self-growing hydrogel particles have emerged as highly …

This article explores challenges in gel treatments, including polymer dissolution, gelation
time, gel strength, stability, resistance to brine flow, and permeability damage in oil …

Excessive water production is a significant challenge during hydrocarbon production from oil
and gas reservoirs, and it is typically controlled by polymer gel placement. However, the …

Polymer gelants are a settled methods for closing off water in lower temperature
arrangements, however stretching out their application to hot reservoirs (> 80° C) presents …

The paper presents the results of laboratory and field experiments on a developed polymer
gel-forming composition “PSB” that enhances oil recovery. In this composition, two aqueous …

In this work, the issue of surfactant adsorption (SA) onto solid surfaces was attempted
through surfactant encapsulation via host–guest interactions using β-CD. Formulations of a …

During enhanced oil recovery (EOR), reservoir heterogeneities and fluids distributions
promote preferential flow channels formation. Therefore, different types of gels have been …

One kind of polymer gel P (AM‐AA‐AMPS) was prepared by radical aqueous
copolymerization, using acrylamide (AM), acrylic acid (AA) and 1‐acrylanmido‐2 …
