  • 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.
  • What is partially hydrolyzed polyacrylamide (PHPA) based high molecular weight drilling polymer?
  • Partially Hydrolyzed Polyacrylamide (PHPA) based high molecular weight drilling polymer for use in controlling of fluid loss and increasing drilling mud viscosity and removal of colloidal from deep drilling foundations such as diaphragm walls, piling concretes, etc.
  • Are PHPA drilling polymers eco-friendly?
  • Key Features and Benefits: Chemtex's PHPA Drilling Polymers when tested for its toxicity level, were found eco-friendly and when compared to its contemporaries such as Bentonites ( Al2H2O6Si). They may not be hazardous to soil but is highly toxic to aquatic life and hence do not find its use in sites beside water bodies.
  • 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.
