  • Is PHPA a water soluble polymer?
  • PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.
  • What is PHPA mud system?
  • SPE Drill Eng 7 (03): 191–199. Mud systems with partially hydrolyzed polyacrylamide polymer (PHPA) are used worldwide and have proved effective and versatile for inhibiting troublesome shale formations. We made significant changes in the generally recommended compositions for these systems and developed a systematic approach to applying them.
  • Is shale stabilized by PHPA?
  • This system has been used for many years as one of the most inhibitive water-based mud systems commercially available to the industry. Observations from both the laboratory and the field indicate that shale is stabilized by the presence of PHPA.
  • Can PHPA mud be used offshore?
  • In North Sea applications, PHPA muds are being used offshore The Netherlands successfully and routinely. However, poor results were obtained in offshore Norway and U.K. applications because of formation reactions, inadequate mixing and solids-control equipment, and general inexperience with water-based muds.
