  • 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.
  • What is drilling mud?
  • Drilling muds consist of suspensions of montmorillonite particles in water or oil which is an inseparable part of the drilling process. Most drilling muds, which are currently used in oil fields, formulated in water 1, 2, 3. Shale hydration during drilling using water-based drilling fluids is a major problem 4.
  • How stable is silica in polyacrylamide based drilling fluid?
  • Kumar et al. (2020) studied the stability of silica in polyacrylamide-based drilling fluid with the saline environment. The result revealed a maximum pH value of 8 with 2 wt% of sodium dodecyl sulphate (SDS) in that drilling fluid maintained loading up to 3 wt% NaCl.
