  • 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.
  • When did hydrolysed polyacrylamide become available?
  • In the 1960s–1970s, hydrolysed polyacrylamide and its derivatives were launched to enhance the drilling operation ( Jiang et al., 2021 ). Partially hydrolysed polyacrylamide (PHPA) became accessible in the foundation industry in the early 1990s ( Lam and Jefferis, 2014 ).
