synthetic polymers: a review of applications in drilling fluids

the main advantages of polymer drilling fluids that distinguish them from others are hydrophilicity and pseudoplasticity, providing them with the ability to change viscosity depending on the shear rate (davoodi et al., 2019; kariman moghaddam et al., 2022). the first deployment of polymer drilling fluid dates back to the 1950s (sun et al., 2021).

recent advances of modified polyacrylamide in drilling

lesser water content in drilling fluid can minimise the shale swelling. in contrary, high water content in drilling fluid may have drawbacks such as high shale, friction, and mud filtrate volume with low plastic viscosity. this leads to the wellbore instability issue (aftab et al., 2017). drilling fluid with low solid content may have high water.

what is flocculation in water treatment,flocculants are essential elements in water treatment processes, especially when it comes to removing suspended particles. my understanding of flocculation in water treatment is that it involves the use of chemicals that cause small suspended particles to clump together to form larger particles known as flocs.

How is polyacrylamide biodegraded?
Both single microbial species as well as mixed populations have been investigated for degradation. Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes.
Is polyacrylate more recalcitrant to biodegradation than amide?
The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties. There are nevertheless reports on microbial growth with polyacrylamide and polyacrylate as the carbon sources.
Can acrylamide be biodegraded?
Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown to utilize, not only acrylamide, but also PAM and its derivatives as the sole source of nitrogen and/or carbon under aerobic as well as anaerobic conditions.
