  • What is PHPA mud?
  • [Drilling Fluids] A class of water muds that use partially hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud. As a shale -control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration.
  • Is PHPA a shale control mud?
  • As a shale -control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration. KCl is used as a shale inhibitor in most PHPA mud designs.
  • What additives were used to prepare a drilling fluid?
  • Ferric chloride hexahydrate (97% extra pure), and ammonia solution (25%) were purchased. Deionized water was prepared using a laboratory water distillation apparatus. All the drilling fluid additives were supplied from Bangladesh Petroleum Exploration and Production Company Ltd. (BAPEX).
  • Can KCl be used as a shale inhibitor in PHPA mud?
  • KCl is used as a shale inhibitor in most PHPA mud designs. In low-solids muds, PHPA interacts with minimal concentrations of bentonite to link particles together and improve rheology without increased colloidal solids loading.
