Abstract: The present invention relates to the use of an aminosulphonate compound corresponding to the following formula (I): R1R2N—CHR3—CHR4—CHR5—SO3− (I) where: R1 is a preferably C2 to C24 alkyl or alkylamido radical; R2 is an optionally hydroxylated alkyl radical; R3, R4 and R5 are, independently of one another, H or OH; it being understood that at least one of the R3, R4 and/or R5 groups is OH, for stabilizing a foam, in particular a foam used to extract hydrocarbons in an underground formation.

Abstract: The invention relates to a method for extracting a crude oil contained in a geological formation, which comprises a step of fracturing said geological formation, by injection of a specific aqueous extraction fluid under pressure, which contains at least one surfactant that reduces the interfacial tension between the extraction fluid and the crude oil to be extracted to below 0.1 mN/m; followed by a discharge step (“flowback”). The invention likewise relates to the original fracturing fluids used in this method, and the additives used in these fracturing fluids.

Abstract: The present invention relates to the preparation of polymers that are of use in particular as a rheology agent, and are suitable for use in very concentrated saline media, which comprises a step of micellar radical polymerization in which are brought into contact, in an aqueous medium: —hydrophilic monomers; —hydrophobic monomers in the form of a micellar solution, containing micelles comprising these hydrophobic monomers; —a radical polymerization initiator; and —preferably an agent for controlling radical polymerization, wherein said micelles comprise at least one surfactant of amphoteric nature. The polymers obtained according to the invention are in particular of use for enhanced oil recovery.
