  • 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.
  • Why does polymer permeability decrease the viscosity of a polymer solution?
  • However, at the same time this property is a weakness in displacing the bypassed oil from the porous media. This is because when the polymer solution passes through the high permeability zone or flow at high rates, the mechanical degradation may occur, thereby decreasing the viscosity of polymer solution.
  • How does concentration affect the viscosity of a polymer?
  • With the increase in the concentration of polymer, the viscosity will be increased. Due to the increased number of polymer molecules in the solution, the interaction between the polymer chains will be more. The molecular weight of the polymer has a drastic effect on the polymer solution viscosity.
  • Why is polyacrylamide used in enhanced oil recovery?
  • The wide use of polyacrylamide (PAM) in enhanced oil recovery generates a large amount of polymer-bearing wastewater featuring high viscosity and difficult viscosity reduction, making the treatment of wastewater increasingly difficult.
