1. A proppant pack comprising:
a plurality of particles, each said particle, comprising a coating of an electrically-conductive metal having a thickness of at least about 270 nm formed on the outer surface of each said particle, wherein each particle has a specific gravity of less than 4 and a size of about 100 mesh to about 10 mesh, wherein the pack has an electrical conductivity, and wherein increasing a load on the pack by a factor of 5 increases the electrical conductivity of the pack by at least 50%. |
