  • Can cationic polyacrylamide be used to quantify polymer zeta potential?
  • However, both cationic and anionic polyacrylamides were used to quantify polymer–shale zeta potential. The anionic polyacrylamide concentration was 0.1–0.2 wt%, such that the concentration is well above C * (critical overlap concentration) and below C ** (critical entanglement concentration).
  • What is the concentration of anionic polyacrylamide?
  • The anionic polyacrylamide concentration was 0.1–0.2 wt%, such that the concentration is well above C * (critical overlap concentration) and below C ** (critical entanglement concentration). The concentration of shale was kept constant at 0.5 lb/bbl, and the concentration of anionic polyacrylamide was varied from 0.1 to 0.2 wt%.
  • 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).
  • 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.
