  • 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 can alumina/polyacrylamide nanocomposite improve the viscosity of drilling fluid?
  • Alizadeh et al. (2015) improved the polyacrylamide by synthesising alumina/polyacrylamide nanocomposite through solution polymerisation. As a result, the viscosity of the drilling fluid was more than 300 cP for freshwater mud at 4 wt% and about 100 cP for saltwater mud at 2 wt%, respectively.
  • How does anionic polyacrylamide interact with shale?
  • The interaction of anionic polyacrylamide with the different shale samples was plotted as a function of anionic polyacrylamide 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).
