Oil production from matured crude oil reservoirs is still associated with low recovery factors. Chemical enhanced oil recovery (EOR) is one of the techniques which can significantly improve the recovery factor of the trapped oil. This is mainly achieved by lowering the interfacial tension (IFT) of the crude oil–brine/aqueous chemical and increasing the viscosity of the injected fluid ...

Which polymers are used in oil fields?

Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

Can modified polyacrylamide be used in drilling technology?

Recent advances of modified polyacrylamide in drilling technology. J. Pet. Sci. Eng. 215, 110566 (2022). Hripko, R., Vajihinejad, V., LopesMotta, F. & Soares, J. B. P. Enhanced flocculation of oil sands mature fine tailings using hydrophobically modified polyacrylamide copolymers. Glob. Chall. 2, 1700135 (2018).

Can polyacrylamide improve hydrocarbon production efficiency?

npj Materials Sustainability 2, Article number: 15 (2024) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.

Can polyacrylamide contribute to residual polymer formation?

Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.

What is hydrolyzed polyacrylamide (HPAM)?

Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.

Are polyacrylamide-degrading bacterial strains isolated from soil?

Two polyacrylamide-degrading bacterial strains were isolated from soil, Bacillus sphaericus and Acinetobacter sp., utilizing 16–19% polyacrylamide after 14 days of cultivation (Matsuoka et al., 2002).
