  • What is high molecular weight partial hydrolysis polyacrylamide (HPAM)?
  • High molecular weight partial hydrolysis polyacrylamide (HPAM) is widely used in the oil recovery, and however, these high molecular weight HPAM will experience a rapid degradation when Fe 2+ was existed in the system. Some studies have implied it was a radical assisted decomposition process.
  • Why is polyacrylamide a high molecular weight polymer?
  • As the representative material, high molecular weight partially hydrolyzed polyacrylamide, because of its extremely high molecular weight and the electrostatic repulsion between the negative carboxylate charges along the polymer chain [ 1, 2 ], it can directly increase the viscosity of the oil recovery water and pump out feasibly.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Which polyacrylamide is used in enhanced oil recovery (EOR)?
  • ABSTRACT High-molecular-weight partially hydrolyzed and sulfonated polyacrylamides are widely used in enhanced oil recovery (EOR). Nonionic polyacrylamide and polyacrylamide-based microgels are also used in water shut-off treatments for gas and oil wells.
