Abstract (en)
[origin: CA3105567A1] The present invention relates to compositions for assisted recovery of oil, comprising: (A) alpha-sulphonated internal ketones of the ketone group; and (B) non-sulphonated internal ketones, with a molar ratio B/(A+B) greater than or equal to the limit molar concentration of non-sulphonated ketones, from which a stabilisation of the reduction in mobility is observed when the mixture of said ketones is introduced into a porous medium.
