Besides, PHPA can be applied in oilfield nowadays, especially in Daqing oilfield, where it is most superior with polymer flooding technique in China (Zhong et al., 2022). PHPA can develop long-chain molecules with their high molecular weight (Lam and Jefferis, 2014), which can overcome the contamination of bacteria and high mechanical force (Zhong et al., 2018).

Interestingly, the flocculants applied are the same PHPA polymers used in drilling fluids. Flocculation is readily achieved in mineral processing applications, but residual PHPA concentrations in these slurries are exceedingly low even after dosing; contrast this to drilling fluids, with PHPA concentrations at least five orders of magnitude higher.

Optimization Of Drilling Fluid Rheological And Fluid Loss Properties Utilizing PHPA Polymer | SPE Middle East Oil and Gas Show and ... - OnePetro

Abstract. Drilling fluids with bentonite can often cause major problems such as flocculation, loss of rheology control and excessive friction due to high clay concentration. Polymers can mitigate such problems, but all these come with much higher costs. Partially hydrolyzed polyacrylamide (PHPA) polymers are used as additives to bentonite water based fluids to stabilize shales and in HTHP
