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 …

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 …

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 …

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 …

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 …

This work constructed transparent fracture models to visually track swollen preformed-
particle-gel (PPG) propagation through open fractures and water flow through PPG placed in …

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

Drilling fluid circulation loss is referred to as “the most severe problem in drilling of oil and
gas wells”, as a routine solution, loss circulation materials are added to fill any fractures and …
