  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • When did polyacrylamide (PHPA) become available?
  • Partially hydrolysed polyacrylamide (PHPA) became accessible in the foundation industry in the early 1990s ( Lam and Jefferis, 2014 ). 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., 2025 ).
  • 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.
  • 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.
