Abstract: A capsule comprising a center section 1 and an outer shell section 2 covering the surface of this center section 1. The center section 1 includes a viscosity-reducing material that reduces the viscosity of a fluid used for hydraulic fracturing. The outer shell section 2 includes a styrene-butadiene copolymer that is capable of controlled release of the center section in the fluid and has a glass transition temperature of -20-80°C.
