Abstract:
A treatment fluid comprising a peroxide source and a perovskite family catalyst is provided. The treatment fluid can be useful in process for breaking the gelled component of a gelled fluid used in downhole operations. In particular, the treatment fluid can be useful in fracturing operations where it can not only break the gelled component of the fracturing fluid but the gaseous oxygen generated by the peroxide source and perovskite family catalyst can be used to further fracture a subterranean formation.

Claim (Index 1):
A method of fracturing a subsurface formation having a well bore extending into the formation, the method comprising the steps of:\n (a) forming a fracturing fluid comprising:\n an aqueous fluid, \n a gelled component, and \n proppant particles; \n (b) introducing the fracturing fluid into a treatment zone of the well under sufficient pressure to generate fractures in the subterranean formation such that at least a portion of the proppant particles are introduced into the fractures; and (c) introducing a perovskite family catalyst and a peroxide source to the subsurface formation such that gaseous oxygen is released which breaks said gelled component.
