  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 × 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012; Joshi & Abed, 2017 ).
  • Can hydrophobically modified polyacrylamide gel be used in high temperature drilling?
  • Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2025.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.
  • Which polymer is used in drilling?
  • Polymer utilisation in drilling mainly depends on its molecular weight and the charge of its molecules. For example, natural polymer (such as polyanionic cellulose, carboxymethyl cellulose xanthan gum, and guar gum) are used in water-based drilling fluid. It can lead to a decrease in fluid loss and an increase in viscosity ( Saboori et al., 2019 ).
  • 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.
