  • Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
  • Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
  • Does high-salinity formation-water affect polyacrylamide viscosity?
  • Polyacrylamides, including partially hydrolyzed polyacrylamide (HPAM), are commonly used for polymer flooding. The soaring demand for polymer flooding has motivated a deeper investigation of the impact of high-salinity formation-water conditions on polyacrylamide’s viscosity.
  • Does nanosilica increase viscosity of polyacrylamide & xanthum gum?
  • Corredor-rojas et al. (2018) also investigated the modified polyacrylamide and xanthum gum with the nanosilica. The viscosity of the polymer was increased after the addition of nanosilica as a cross-linker between the polymer chains. Unmodified silica was unable to mitigate the viscosity reduction when temperature increased.
  • 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 ).
