  • Which crosslinker is used in polyacrylamide drilling fluid?
  • Hamza et al. (2021) utilised aluminium acetate as the crosslinker in polyacrylamide drilling fluid. Since the inorganic crosslinkers are pH sensitive and can readily form a gel at low pH, the acetate group is the optimum chemical group for enhancing gelation and retardation effect.
  • 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.
  • What is the temperature of cross-linked polyacrylamide gel?
  • Deng ( Deng et al., 2018) experimentally studied cross-linked polyacrylamide gel using the microencapsulated initiator to control the gelation time, yet temperature of this gel is limited to 90 °C for application.
  • How is cross-linked polyacrylamide gel prepared?
  • Preparation of polyacrylamide gel Cross-linked polyacrylamide gel was prepared by free radical polymerization of AM and MBA in aqueous solution with encapsulated initiator. 7% (w/v) AM, 0.5% (w/v) MBA and 5% (w/v) NaCl were dissolved in 300 mL distilled water at room temperature for 30 min until totally dissolved.
