    摘要： 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. Oxidizing agents such as air, oxygen, persulfates, bromates, peroxides, and others are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger. In certain brines, for example bromide brines, certain zwitterionic viscoelastic fluid systems that can decarboxylate and that require an anion-containing co-surfactant undergo delayed degradation if oxygen is present, for example from fluid preparation or in a foam.

    摘要： A system includes a wellbore intersecting a subterranean formation and a treatment flowpath disposed in the wellbore including a fluid path from a surface location to the subterranean formation and returning to the surface location. The treatment flowpath has a delivery flowpath upstream of the subterranean formation and a pertinent flowpath at and downstream of the subterranean formation. The system further includes a gravel pack assembly having a first crossover port fluidly coupling the delivery flowpath to the pertinent flowpath, a screen, a washpipe, and a second crossover port fluidly coupling the washpipe to a return portion of the pertinent flowpath. The system further includes a friction reducing agent that is effective in at least part of the pertinent flowpath, but that is not a friction reducer in solution in the treatment fluid at the surface location.
