What is partially hydrolyzed polyacrylamide (PHPA)?

Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.

Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?

PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2022; Liu et al., 2016; Xiong et al., 2018).

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).

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 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.

Is HPAM a water soluble polymer?

HPAM is a water-soluble, commonly injected polymer into oil reservoirs to improve the water flooding process (Xue et al., 2022; Zhao et al., 2008).
