ABSTRACT:
The invention concerns an aqueous viscoelastic fluid for use in the recovery of hydrocarbons. According to the invention this fluid comprises a first viscoelastic surfactant and a second surfactant able to decompose under downhole conditions to release a compound itself able to reduce the viscosity of the aqueous viscoelastic fluid.
