  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
  • Is partially hydrolyzed polyacrylamide biodegraded by bacterial strains isolated from Omani oil fields?
  • In present study the biodegradation of partially hydrolyzed polyacrylamide (HPAM) by bacterial strains isolated from Omani oil fields was analyzed. HPAMs are extensively used in oil fields for enhanced oil recovery operations.
  • Which polymer based enhanced oil recovery (EOR) process uses partially hydrolyzed polyacrylamides?
  • Worldwide partially hydrolyzed polyacrylamides (HPAM) are preferentially used for polymer-based enhanced oil recovery (EOR) processes, due to cost-competiveness.
  • What is partial hydrolyzed polyacrylamide (HPAM)?
  • Partially hydrolyzed polyacrylamide (HPAM) is a water-soluble polymer material used in oil fields [ 18, 19 ]. It usually has a linear structure with high molecular weight [ 20] and is obtained by partial hydrolysis of PAM or by copolymerization of sodium acrylate with acrylamide [ 21 ].
