  • 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.
  • Why is HPAM a high viscosity polymer?
  • HPAM solution must maintain high viscosity to effectively mobilize oil. In reality however, polymer is very sensitive to salinity and hardness of base water and underground water. This phenomenon is studied in this paper. The two HPAM test samples have molecular weight of 10 million and 20 million Dalton.
  • 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.
  • What factors affect a polymer solution viscosity?
  • These correlations account for the individual as well as combined effects of four major parameters; namely, shear rate, concentration, molecular weight and degree of hydrolysis, on polymer solution viscosities. Viscosities of various polymers solutions have been measured.
