Brine-resistant sulfonate surfactants for enhanced oil recovery

Conference · · Soc. Pet. Eng. AIME, Pap.; (United States)
OSTI ID:6032941
One of the most severe limitations of surfactant waterflooding is the instability of the commonly employed surfactants in the usual ionic environments of oil reservoirs. A specific modification to the usual structure of sulfonate surfactants not only makes them immune to high concentrations of monovalent and divalent cations, but also enables them to act as stabilizer of the common surfactants and to displace tertiary oil in brines of high salinity and divalent ion content.
