  • 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.
  • 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.
  • Can PHPA be used in laboratory mud?
  • However, we have used 1lbm/bbl [2.9-kg/m3] PHPA concentration in NaCI and KCl muds in mud weights> 18 Ibm/gal [>2160 kg/m3] successfully. Interestingly, laboratory muds prepared with 1.01bmlbbl [2.9 kg/m3] PHPA at 18lbm/gal [2160 kg/m3] are much too viscous to pump.
