Complex fluid flow in porous media is ubiquitous in many natural and industrial processes.
Direct visualization of the fluid structure and flow dynamics is critical for understanding and …

Unwanted water production is a serious issue in oil-and gas-producing wells. It causes
corrosion, scale, and loss of productivity. One method of treating this problem is to …

Polymer gel systems as water management materials have been widely used in recent
years for enhanced oil recovery applications. However, most polymer gel systems are …

Hydrogels hold promise in agriculture as reservoirs of water in dry soil, potentially alleviating
the burden of irrigation. However, confinement in soil can markedly reduce the ability of …

Preformed particle gel (PPG) is a particled superabsorbent crossklinking polymer that can
swell up to 200 times its orginal size in brine. The use of PPG as a fluid-diverting agent to …

Gel treatment is one of the most efficient enhanced oil recovery techniques used for
conformance control. In recent years, preformed particle gels (PPG) have gained attention …

In recent years, polymer micro/nanogels which are re-crosslinked polymers with 3D
networks, have attracted a lot of interest in Enhanced Oil Recovery (EOR) field. In size of …

Branched-preformed particle gel (B-PPG) is a newly developed chemical agent for
enhanced oil recovery in heterogeneous reservoirs. In this paper, laboratory experiments …

As a promising method of carbon emission reduction, carbon capture, utilization and storage
(CCUS) is an important technology to achieve carbon neutrality. CO 2 geological storage is …

High water production is a common problem in mature oil reservoirs. Gel-based treatments
have been widely used as blocking agents to control water production in heterogeneous …
