  • 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 is PHPA mud?
  • PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. We have several grades to offer to meet our client’s need with variants.
  • Can KCl/PHPA shale inhibition system be used as drilling fluid?
  • The present KCl/PHPA shale inhibition system can advantageously be used as drilling fluids required for drilling in any shale formation, provided that the formulation of the mud must be optimized. Hydrophobically associating polyacrylamides and their partially hydrolyzed derivatives prepared by post-modification.
  • Can you drill cement with PHPA mud?
  • Do not drill cement with PHPA muds, unless the system will be replaced after drilling out, because PHPA muds are sensitive to high pH, especially in the presence of high calcium levels. If drilling cement with a PHPA system is unavoidable, pretreat the system with 0.251bmlbbl [0.7 kg/m3] sodium bicarbonate.
