  • What is modified polyacrylamide?
  • There are many drawbacks to the use of bentonite, natural polymer, and synthetic polymer. Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity.
  • Can HPAM be used as a lubricant mud?
  • Furthermore, HPAM is traditionally used with KCl as a polymer, which acts by encapsulation of clay [ 22 ], at very high concentration, for the coating of the clays, improving the load capacity of the overburden and functioning as power lubricant mud.
  • What is modified polyacrylamide drilling fluid?
  • Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
  • 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.
