Methods and compositions for fracturing subterranean formations

A method for fracturing a subterranean formation comprising:

• introducing a viscoelastic surfactant gelled fluid into a subterranean formation, where the viscoelastic surfactant gelled fracturing fluid composition comprises:
• water;
• at least one viscoelastic surfactant (VES) in an amount effective to increase the viscosity of the water;
• at least one internal breaker selected from the group consisting of bacteria, saponified fatty acids, mineral oils, hydrogenated polyalphaolefin oils, saturated fatty acids, unsaturated fatty acids, and combinations thereof;
• at least one fluid loss control agent selected from the group consisting of alkaline earth metal oxides, alkaline earth metal hydroxides, transition metal oxides, transition metal hydroxides, and mixtures thereof;
• and
• at least one viscosity enhancer selected from the group consisting of pyroelectric particles, piezoelectric particles, and mixtures thereof;
• where the viscosity enhancer has a particle size ranging between about 1 nanometer up to about 2 microns;
• pumping the fracturing fluid composition against the subterranean formation at sufficient rate and pressure to fracture the formation;
• and
• reducing the viscosity of the VES gelled fluid with the internal breaker.
