VISCOELASTIC SURFACTANT FLUIDS HAVING ENHANCED SHEAR RECOVERY, RHEOLOGY AND STABILITY PERFORMANCE

摘要

A method of treating a subterranean formation by injecting down a well an aqueous fluid containing a viscoelastic surfactant fluid comprising an enhanced shear recovery agent wherein shear recovery time of the viscoelastic surfactant fluid is reduced by the addition of the enhanced shear recovery agent, and a viscoelastic surfactant fluid composition thereof.
