  • 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.
  • 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 thermal conductivity of polyacrylamide based drilling fluid?
  • It showed thermal conductivity around 0.9 Wm −1 K −1 that have 84% improvement when compared to the bare polyacrylamide. Study of filtration and rheological properties in polyacrylamide-based drilling fluid using graphene oxide
  • What is the pH range of modified polyacrylamide drilling fluid?
  • Besides, Shettigar et al. (2018) also developed a modified grafted polyacrylamide by maintaining the pH value of 9 by using sodium hydroxide. In short, the modified polyacrylamide drilling fluid must be maintained at a pH range of 7–10 to avoid an acidic environment that is harmful to the environment and society.
