  • 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 is hydrolyzed polyacrylamide (HPAM)?
  • Materials Hydrolyzed polyacrylamide (HPAM) was provided by Shandong Polymer Biochemicals CO., Ltd. China. It has molecular weight of 24 million with 25% degree of hydrolysis.
  • Do modified CMC and PHPA polymer drilling fluids affect rheological properties?
  • Kuma et al. investigated modified CMC and PHPA polymer drilling fluids with NaCl and KCl and haematite mineral where KCl and NaCl acted as great swelling inhibitors for drilling muds, while haematite just slightly increased the rheological properties on CMC–bentonite mud and did not have much effect on the PHPA–bentonite mud [ 26 ].
