Experimental and numerical simulation studies of the zwitterionic polymers for enhanced oil recovery.

ABSTRACT: In this study, three zwitterionic copolymers, zPAM 1, zPAM 2, and zPAM 3, were synthesized by copolymerizing acrylamide with sulfobetaine-based monomers to investigate their suitability for polymer flooding in high salinity environment. These polymers were selected due to their strong hydration capability, high glass transition temperature and enhanced salinity and thermal tolerance compared to other polymers. The aim of this study was to enhance the thermal and salinity tolerance of polymers while improving their mobility control, with the ultimate goal of increasing oil displacement efficiency. The successful synthesis of the polymers was confirmed by FTIR spectroscopy, which identified characteristic zwitterionic functional group peaks, and 1 H NMR spectroscopy, which provided detailed
