摘要
This resin composition is used in order to form a surface layer which coats at least part of the outer surface of particles that are filled into fractures formed in a subterranean layer, and contains a thermosetting resin and a hydrophilic polymer. This resin composition ideally further contains a surfactant. In this invention, the effect of the thermosetting resin of acting to prevent dissipation of core particle debris and the effect of the hydrophilic polymer of acting to increase affinity for water (i.e. repellency of the fluid to hydrocarbons) work synergistically to increase the fluid penetration of the coated particles in the filling sites (subterranean fractures).
