  • Does the viscosity of polyacrylamide aqueous solution change with age?
  • However, the properties of fresh polymer solutions are unsteady. It has been found that the viscosity of polyacrylamide aqueous solution significantly changes with age for a given initial solution [32, 33], and the trends are highly dependent on the solution's concentration and temperature .
  • 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 , , , .
  • Can thermogravimetric analysis predict long-term stability of polyacrylamide-type polymers?
  • This study aims to apply thermogravimetric analysis technology to develop a facile way for long-term stability prediction of polyacrylamide-type polymers at high temperature and high salinity reservoir conditions, to maintain sufficient viscosity in chemical flooding.
  • 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.
