摘要：
Methods for reducing a viscosity of a viscosified fluid include reacting, such as by depolymerizing and/or decomposing, a polymeric material of the viscosified fluid with a breaking agent including one or more organic peroxide breakers having a structural feature selected from a cyclic peroxide segment and/or multiple linear peroxide moieties per molecule. The methods of treating the subterranean are provided that include reacting, such as by depolymerizing and/or decomposing, a polymeric material of a viscosified treatment fluid with one or more organic peroxide breakers having a structural feature selected from cyclic peroxide segment and/or multiple linear peroxide moieties per molecule to facilitate breaking of the viscosified treatment fluid after the fracturing or treatment is finished.
