  • 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 an anionic polymer withstand drilling fluid?
  • The fluid loss test on this drilling system found that anionic polymer can resist about 4.5 × 105 ppm of Cl −, 4 × 105 ppm of Ca 2+, and 1.5 × 104 ppm of Mg 2+ at low pH by adding the acidic gas together at 180 °C. Thus, it can withstand the temperature of drilling fluid up to 180 °C.
  • What is the role of polyacrylamide for drilling mud additives?
  • 1.Polyacrylamide for drilling mud additives. Drilling fluid in oil extraction works as drilling mud performance adjuster. PAM role is to adjust the rheology of drilling fluid, carrying cuttings, lubrication drill bit, favorable drilling.
  • 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.
