description A degradation agent for viscous fluids to be used in hydraulic fracturing methods is provided according to one aspect of the present invention, the degradation agent comprising a persulfate and an iron salt serving as an activator for the persulfate, wherein the persulfate and the iron salt have been coated and the ratio of the coating-film thickness (Y) in the iron salt to the coating-film thickness (X) in the persulfate, Y/X, is in the range of 0.35 to 1.0. The degradation agent for viscous fluids has properties suitable for use in hydraulic fracturing methods.
