POLYMERIC ADDITIVES FOR ENHANCEMENT OF TREATMENT FLUIDS COMPRISING VISCOELASTIC SURFACTANTS AND METHODS OF USE

摘要

Polymeric additives used with viscoelastic surfactants, fluids comprising such additives and viscoelastic surfactants, and associated methods of use, are provided. In one embodiment, the methods comprise: providing a treatment fluid that comprises an aqueous base fluid, a viscoelastic surfactant, and an amphiphilic polymer, the amphophilic polymer comprising a hydrophobic component, and a hydrophilic component comprising at least 15 monomer units; and introducing the treatment fluid into at least a portion of a subterranean formation.
