Abstract
A resin composition is used for forming a surface layer coating at least a part of an outer surface of a particle. The particle is adapted to be packed into a fracture formed in a subterranean formation, and contains a thermosetting resin and a hydrophilic polymer. It is preferred that the resin composition further contains a surfactant. According to the present invention, it is possible to provide an effect of preventing pieces of core particles from being scattered due to the action of a thermo-setting resin and an effect of improving compatibility with respect to water (that is, fluid repellent with respect to hydrocarbon) due to the action of a hydrophilic polymer in a synergistic manner. This increases conductivity of packed spaces of a subterranean formation (that is, fractures of the subterranean formation) in which coated particles are packed.
