A method for increasing the rate of shear rehealing of fluids made with cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a rheology enhancer package containing, for example a polyethylene glycol - polypropylene glycol block copolymer and a polynaphthalene sulfonate. The rheology enhancer package allows viscoelastic surfactant fluids to be used at lower viscoelastic surfactant concentrations in certain applications, for example certain oilfield treatments, for example fracturing and gravel packing. Preferred surfactants are betaines and quaternary amines.

L'invention concerne un procédé permettant d'augmenter la vitesse de régénération du cisaillement de liquides réalisée avec des systèmes fluides d'un tension-actif viscoélastique cationique, zwitterionique et amphotère par adjonction d'une dose efficace d'un activateur de rhéologie contenant, par exemple, un copolymère bloc glycol polyéthylène - glycol polypropylène et un sulfonate polynaphtalène. L'ensemble activateur de rhéologie permet d'utiliser des fluides de tensio-actifs viscoélastiques à de plus faibles concentrations dans certaines applications, par exemple dans les traitements de champs pétrolifères, notamment en matière de fracturation et de gravillonnage. Les bétaïnes et les amines quaternaires sont des tensio-actifs préférés.
