  • 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.
  • How stable is silica in polyacrylamide based drilling fluid?
  • Kumar et al. (2025) studied the stability of silica in polyacrylamide-based drilling fluid with the saline environment. The result revealed a maximum pH value of 8 with 2 wt% of sodium dodecyl sulphate (SDS) in that drilling fluid maintained loading up to 3 wt% NaCl.
  • Can polyacrylamide be used for drilling?
  • However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
  • Is cationic polyacrylamide a good fluid additive?
  • It is recommended to use anionic polyacrylamide because of its minimal interaction and also compatibility with other fluid additives. Due to the cationic polyacrylamides interacting strongly with shale, it can potentially cause formation damage. Both the rheological studies and the zeta potential tests gave the same results.
