  • Does encapsulation of cutting particles based on PHPA polymers prevent flocculation?
  • Conclusions The effective encapsulation of cutting particles suspended in drilling fluids based on PHPA polymers severely limits (if not prevents) subsequent flocculation by dosing similar anionic flocculants.
  • Which polymer is used in water based drilling fluids?
  • In conventional water-based drilling fluids, bentonite, natural polymer, and synthetic polymer were discovered in the past. There are many drawbacks to the use of bentonite, natural polymer, and synthetic polymer. Consequently, polymer modification is required in drilling nowadays.
  • Do modified CMC and PHPA polymer drilling fluids affect rheological properties?
  • Kuma et al. investigated modified CMC and PHPA polymer drilling fluids with NaCl and KCl and haematite mineral where KCl and NaCl acted as great swelling inhibitors for drilling muds, while haematite just slightly increased the rheological properties on CMC–bentonite mud and did not have much effect on the PHPA–bentonite mud [ 26 ].
  • What is the pH range of modified polyacrylamide drilling fluid?
  • Besides, Shettigar et al. (2018) also developed a modified grafted polyacrylamide by maintaining the pH value of 9 by using sodium hydroxide. In short, the modified polyacrylamide drilling fluid must be maintained at a pH range of 7–10 to avoid an acidic environment that is harmful to the environment and society.
