What is claimed is:
1. An electrically conductive proppant particle, comprising:
a sintered, substantially round and spherical particle having less than about 30% crush at 4,000 psi and a specific gravity of about 3.8 g/cm3 or less; and
a plurality of conductive particles,
wherein the sintered, substantially round and spherical particle has one or more pores and at least one of the plurality of conductive particles is disposed within at least one of the one or more pores,
wherein the at least one of the plurality of conductive particles is mixed with an activator to provide an activator mixture that is infused into the one or more pores, and
wherein the activator mixture elutes from the one or more pores so that the at least one conductive particle is located at a surface of the electrically conductive proppant particle after the electrically conductive proppant particle has been introduced to a subterranean fracture.
●形容詞 substantially round and sphericalはほぼ球状という意味です。
substantially（実質的に）が付いていることで形状の範囲が真球より広げられています。
●3種類のparticleが出てきますね。
