Abstract: A method for hydraulic fracturing of a subterranean formation includes injecting an oil-based fracturing fluid into the subterranean formation through a well. The method also includes injecting a second fracturing fluid, for example a water-based fracturing fluid, into the subterranean formation through the well after completion of the injection of the oil-based fracturing fluid.

Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Acidic internal breakers such as sulfuric acid and nitric acid are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger.
