  • Publication number: 20150203744
    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.

  • Patent number: 9085666
    Abstract: The present invention is a method for decomposing a polymer material by chemically decomposing a polymer material containing a first monomer and a second monomer in a mixture of the polymer material with the first monomer or a derivative of the first monomer to produce a chemical raw material. A relationship between a proportion of number of molecules of the second monomer to number of molecules of the first monomer in a reaction system for decomposing the polymer material and the molecular weight of the chemical raw material produced in the reaction system is acquired in advance (S101). Subsequently, an addition mount of the derivative of the first monomer to be added to the polymer material is determined based on the above relationship (S102). The first monomer in the addition amount determined is then mixed with the polymer material (S103).
