  • Is polyacrylamide mud suitable for drilling water-sensitive shales?
  • Clark, R.K. et al. (1976) Polyacrylamide/potassium chloride mud for drilling water-sensitive shales. Journal of Petroleum Technology, June, 719; also in Transactions AIME, 261. Steiger, R.P. (1982) Fundamentals and use of potassium/polymer drilling fluids to minimize drilling and completion problems associated with hydratable clays.
  • Why is polyacrylamide used in water treatment and sludge dewatering?
  • Polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. The efficiency of flocculation is influenced by factors such as the type of flocculant used, its molecular weight, and its concentration in the water suspension.
  • Does water based mud affect shale hydration?
  • The expansibility and mechanical properties of shale are significantly influenced by water-based muds (WBMs); thus, it is necessary to mitigate this effect to avoid borehole instabilities in drilling operation. Potassium chloride (KCl) is usually used as inhibitor to reduce hydration of shales.
  • Can microblocked polyacrylamide improve municipal sludge dewaterability?
