Abstract:
This invention relates to a surfactant composition, production and use thereof in tertiary oil recovery. The present surfactant composition comprises a cationic-nonionic surfactant and an anionic surfactant, and exhibits significantly improved interfacial activity and stability as compared with the prior art. With the present surfactant composition, a flooding fluid composition for tertiary oil recovery with improved oil displacement efficiency and oil washing capability as compared with the prior art could be produced.
