  • Does high-salinity formation-water affect polyacrylamide viscosity?
  • Polyacrylamides, including partially hydrolyzed polyacrylamide (HPAM), are commonly used for polymer flooding. The soaring demand for polymer flooding has motivated a deeper investigation of the impact of high-salinity formation-water conditions on polyacrylamide’s viscosity.
  • Does polymer flooding affect viscosity in high-salinity formation-water?
  • According to the reports from oilfields in which polymer flooding has been applied, 5–4 it is a big challenge to maintain the polymer’s viscosity in high-salinity formation-water. Polyacrylamides, including partially hydrolyzed polyacrylamide (HPAM), are commonly used for polymer flooding.
  • Can hydrolyzed polyacrylamide be degraded?
  • For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.
  • Does calcium concentration affect molecular configuration and viscosity of polyacrylamide molecules?
  • Partially hydrolyzed polyacrylamide molecules in high-salinity formation-water solution are simulated using the molecular dynamics method to investigate the impact of calcium concentration on molecular configuration, network, and viscosity from microscopic dense to dilute phases. The key results are as follows:
