Abstract
A method of reducing the viscosity of a viscosified fluid in an underground drilling operation comprising, where the introduction of a chelated transition metal catalyzes the viscosity reduction of the viscosified fluid. The chelated transition metal may be ferric methylglycinediacetate. Additionally, an uninhibited oxidizing agent, such as a peroxygen compound, may also be present in combination with the chelated transition metal to catalyze the viscosity reduction of the viscosified fluid.
