  • 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.
  • 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.
  • Are bulk gels based on NPAM suitable for profile control technology?
  • However, no systematic study has been done for the gelation performance and microstructure of bulk gels under hydrated conditions and in porous media. So in this research, we focused on the gels based on NPAM for in-depth profile control technology.
  • What are the different types of polyacrylamide adsorption polarities?
  • Specifically, it can be divided into non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), and cationic polyacrylamide (CPAM). C 3 H 7 ON, C 3 H 6 O 2, and C 5 H 9 O 2 N + are the basic structural units of these PAM, resulting in different adsorption polarities [ 12, 13 ].
