  • 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.
  • 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.
  • Why are polyacrylamide-type polymers limited to high temperature and salinity?
  • However, many polyacrylamide-type polymers are limited for reservoirs with high temperature (above 90 ℃) and high salinity (above 50,000 ppm), as they are susceptible to losing viscosity due to chemical and thermal degradation in aqueous environment , , , .
  • Which polymers are good candidates for high temperature and high salinity conditions?
  • The evaluation results demonstrate that all the samples present good long-term stability with half-lives more than 90 days. This fact further proves our previous study that polymers with high values of T 15 or T 20 can be good candidates for high temperature and high salinity conditions.
