  • 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.
  • Does a single hydrolysed polyacrylamide chain reduce viscosity in the presence of CQD?
  • To provide molecular insight into the reported unconventional viscosity reduction of HPAM in the presence of CQD, the conformational behaviour of a single hydrolysed polyacrylamide (HPAM) chain in the presence of a CQD representing a typical dilute solution, was investigated by atomistic molecular dynamics simulations.
  • Can polyacrylamide contribute to residual polymer formation?
  • Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
