Foaming compositions for enhanced oil recovery
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; andpolymers 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 les...

| description | 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; andpolymers 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; andthe 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. |
