Abstract: The invention relates to a composition C which comprises, in an aqueous medium M: surfactants suitable for creating a foam in the presence of a gas; and polymers P based on acrylamide or acrylamido units, having a molecular mass of 1,000,000 to 20,000,000 g/mol; or: composition C has a viscosity of less than 6 mPa·s; and the content of polymer P is greater than the concentration limit beyond which the apparent viscosity of a foam obtained from composition C is greater by at least 10% than the apparent viscosity of a foam obtained from the same composition but deprived of polymers. The invention further relates to the use of these compositions as foaming compositions for EOR.

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: An aqueous formulation for enhanced oil recovery may include at least one surfactant and at least one associative polymer. The associative polymer may be obtained by micellar radical polymerization by bringing into contact, in an aqueous medium, hydrophilic monomer dissolved in the aqueous medium, hydrophobic monomers in the form of a micellar solution, at least one radical polymerization initiator, and preferably at least one radical polymerization control agent.
