| description | In accordance with the present invention, the rheology of an aqueous fluid is modified by a method which comprises adding to said aqueous fluid an amount of a viscoelastic composition sufficient to form a viscoelastic fluid. The viscoelastic composition of the invention comprises a combination of i) at least one alkyl amido quaternary amine, and ii) at least one coadditive that comprises a C8-24 linear alkyl and/or alpha-olefin sulfate and/or sulphonate.
Selon la présente invention, la rhéologie d'un fluide aqueux est modifiée par une méthode comprenant l'ajout audit fluide aqueux d'une quantité d'une préparation viscoélastique suffisante pour former un fluide viscoélastique. La préparation viscoélastique selon l'invention comprend une combinaison de i) au moins une alkylamidamine quaternaire, et ii) au moins un co-additif qui comprend un alkyle linéaire en C8-C24 et/ou un sulfate et/ou sulfonate d'alpha-oléfine. |
