The aging of the existing reservoirs makes the hydrocarbon extraction shift toward newer
reserves, and harsh conditioned carbonates, which possess high temperature and high …

Understanding polymer retention is a critical aspect in the field of chemical-enhanced oil
recovery (cEOR). This article presents a comprehensive review of polymer retention in …

Greater than 50% of the original oil in place turns into immobile or trapped oil because of
unfavored mobility and capillary forces problems. More efficient methods should be …

Polymer gels can be effectively applied to plug fractured reservoirs and carbonate cave
strata. Herein, polyvinyl alcohol (PVA), acrylamide, and 2-acrylamido-2-methyl-1 …

Polymer gels are widely used in the oil and gas industry, and high-molecular-weight
polymer gels have significant effects on reservoir water plugging operations. Based on …

In this research, the extracted mucilage from Chia seeds is introduced as a new natural
polymer for use in polymer injection into oil reservoirs. Chia seeds polymer (CSP) is …

Coupling polymer with low-salinity water (LSW) to promote enhanced oil recovery (EOR) in
carbonate reservoirs has attracted significant interest in the petroleum industry. However …

Natural polymers have been investigated as part of the endeavors of green chemistry
practice in the oil field. However, natural polymer studies are still preliminary. The current …

Polymer flooding in carbonate reservoirs is greatly affected by polymer retention, which is
mainly due to polymer-rock surface interactions. Consequently, this leads to a delay in …

Due to the challenges posed by high injection pressure and significant viscosity shear loss,
conventional polymer flooding methods are unable to effectively meet the urgent demand for …
