  • Are polymers thermally stable in the Middle East?
  • Most of Middle East fields presents harsh reservoir conditions (high temperature, high salinity, low permeability carbonates) for polymers used as mobility control agents in EOR. Traditional synthetic polymers such as partially hydrolyzed polyacrylamide (HPAM) are not thermally stable.
  • Do polyacrylamide-type polymers have good thermal stability?
  • Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.
  • What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?
  • Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.
  • How to predict long-term stability of polyacrylamide-type polymer under high temperature and salinity?
  • A facile model was developed by TGA method for long-term stability prediction of polyacrylamide-type polymer under high temperature and high salinity conditions. Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions.
