  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • Does glyoxal and polyacrylamide have a gel phase?
  • The mixture of polyacrylamide and glyoxal presents always as sol at low polymer concentration ( C<C ∗ ), irrespective of the glyoxal concentration is. A gel phase appears at a polymer concentration superior to C ∗.
  • How does polyacrylamide glyoxal gelation work?
  • As mentioned above, under appropriate conditions, the mixture of polyacrylamide and glyoxal undergoes a transition from a purely viscous liquid (sol) to a more structured viscoelastic fluid (gel). The gelation process can be followed by means of rheological measurements.
