  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • Partially hydrolyzed polyacrylamide (PHPA) is the most frequently used polymer in this respect, owing to its low cost, viscosifying nature, and well-known physiochemical properties (Urbissinova et al. 2010 ). The molecule of this polymer is a flexible chain which remains in coil-like structure in the absence of a shearing effect.
  • What does partially hydrolyzed polyacrylamide mean?
  • What Does Partially Hydrolyzed Polyacrylamide Mean?
  • Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids.
  • How does PHPA affect fluid rheology?
  • The introduction of higher molecular weight synthetic polymers typified by partially hydrolysed polyacrylamide (PHPA) allowed the same effect on fluid rheology to be achieved at much lower additive concentrations, a major practical advantage.
  • What is a PHPA mud system?
  • The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. PHPA can be used in mud systems varying from low solids to weighted muds systems utilizing fresh or saltwater. PHPA is a white granular powder, anionic in nature having a specific gravity of 1.25 to 1.40 and a bulk density of 40 to 46 lb/ft 3.
