McCoy, D R; Gipson, R M; Naylor, C G

A dicyclopentadiene derived ethoxysulfonate alone or combined with a petroleum sulfonate surfactant is dissolved in water to form an effective surfactant fluid that is stable in high salinity and/or high temperature environments. The surfactant fluid is injected into an underground petroleum-containing reservoir in an enhanced oil recovery process.
