Abstract:
A capsule comprising a center section and an outer shell section 2 covering the surface of this center section. The center section includes a viscosity-reducing material that reduces the viscosity of a fluid used for hydraulic fracturing. The outer shell section 2 includes a plurality of particulate matter 3 and a holding material that holds the plurality of particulate matter 3 and is capable of sustained release of the center section in the fluid. In the outer shell section 2, the plurality of particulate matter 3 is distributed such that the content amount has at least one maximum in directions away from the center section.
