Abstract
A treatment fluid comprising a peroxide source and a perovskite family catalyst is useful in processes 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.
