Abstract: The present invention relates to compositions for enhanced oil recovery, comprising: (A) internal ketones sulfonated alpha to the ketone group; and (B) unsulfonated internal ketones, with a molar ratio B/(A+B) greater than or equal to the limiting molar concentration of unsulfonated ketones from which a stabilization is observed in the reduction in mobility when the mixture of said ketones is injected into a porous medium.

Abstract: A compound of general formula (I) or (II), wherein Rn and Rm independently represent a C3-C27 aliphatic group, R1 to R4, which may be the same or different at each occurrence, represent hydrogen or a C1-C8 alkyl group, X1 and X2, which may be the same or different at each occurrence, represent a linear or branched divalent hydrocarbon radical with 1 to 24 carbon atoms which can be optionally substituted and/or interrupted by one or more heteroatoms or heteroatom containing groups, and R5 and R6, which may be the same or different at each occurrence, represent a group selected from —O−, -Alk-CH(OH)—CH2—SO3— and -Alk-CO2— wherein Alk represents an alkylene group.
