DOI: 10.1002/app.45413
Abstract: Conformance control using preformed gels (PGs) is an effective method to reduce water cut in production oilwells. However, PGs are unable to thicken formation of water, and the improvement of water-oil mobility is limited. Compared… read more here.

DOI: 10.1016/j.petrol.2019.106556
Abstract: Abstract High molecular weight polyfluoroacrylate (PFA) is an amorphous, sticky, hydrophobic, oil-phobic, CO2-soluble homopolymer. 1 wt% PFA-in-CO2 solutions are four times as viscous as pure CO2. Although these solutions provided modest mobility control, unexpectedly large increases… read more here.

DOI: 10.1016/j.petrol.2020.108199
Abstract: ABSTRACT The existence of fractures in petroleum reservoirs can greatly reduce the sweep efficiency and subsequently limit the oil recovery during water flooding. Gel treatment is widely known as a cost-effective method for conformance control… read more here.

DOI: 10.1021/acsami.0c09958
Abstract: Conformance control during waterflooding in an oil reservoir is utilized to redistribute water and increase the sweep efficiency and hence oil production. Using preformed gel particles can effectively redirect the flow by blocking the high… read more here.
