  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • 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. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.

  • 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.
  • Are aqueous solutions of partially hydrolyzed polyacrylamides used in deep foundations?
  • Since the early 1990s, aqueous solutions of partially hydrolyzed polyacrylamides (PHPA) also have been used for the construction of deep foundations in many different countries (e.g., Ata and O’Neill 1997; Lam and Jefferis 2014b). PHPA is a synthetic polymer comprising repeating units of acrylamides and acrylates.
