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.
