  • 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.
  • 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 HPAM increase viscosity in partially hydrolyzed polyacrylamide solution?
  • From the average end-to-end distances of HPAM molecules in each partially hydrolyzed polyacrylamide solution system in Fig. 16, it can be seen that HPAM molecules maintain a relatively stretched state in the solution, and the hydrodynamic radius is large, which significantly increases the solution 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.
