  • Denaturing Polyacrylamide/Urea Gel Electrophoresis

    2020-5-4 · The application of polymer-based relative permeability modifiers (RPM) in low-permeability sandstone reservoirs has long intrigued production engineers. We hypothesize that lowering salinity may expand the application of the cationic polyacrylamide (CPAM) in low-permeability sandstone gas reservoirs, because of the favorable polymer–polymer physiochemical interaction at pore surfaces. To ...

    2011-1-20 · The hydrophobically associating cationic fluorinated polyacrylamide (CFPAM), modified with fluorinated acrylate, 2-(perfluorooctyl)ethyl acrylate (FEA), has been newly synthesized, by free radical micellar copolymerization in aqueous solution. The solution properties of these polymers were investigated in details in this study. In addition, the flocculation of CFPAM was also evaluated.
