  • METHOD OF VISCOSITY REDUCTION IN THE PRESENCE OF FULLY COORDINATED COMPOUNDS
    Publication number: 20150175880
    Abstract: 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 a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound. 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 a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound, to facilitate breaking of the viscosified treatment fluid after the fracturing or treatment is finished.
