    摘要： Methods for manufacturing electrically-conductive proppant particles are disclosed. The methods can include preparing a slurry containing water, a binder, and a raw material having an alumina content, atomizing the slurry into droplets, and coating seeds containing alumina with the droplets to form a plurality of green pellets. The green pellets can be contacted with an activation solution containing at least one catalytically active material to provide activated green pellets including the at least one catalytically active material. The method can include sintering the activated green pellets to provide a plurality of proppant particles. The plurality of proppant particles can be contacted with a plating solution containing one or more electrically-conductive material to provide electrically-conductive proppant particle.

    摘要： Methods and systems for determining subterranean fracture closure are disclosed herein. The methods can include electrically energizing a casing of a wellbore that extends from a surface of the earth into a subterranean formation having a fracture that is at least partially filled with an electrically conductive proppant and measuring a first electric field response at the surface or in an adjacent wellbore at a first time interval to provide a first field measurement. The methods can also include measuring a second electric field response at the surface or in the adjacent wellbore at a second time interval to provide a second field measurement and determining an increase in closure pressure on the electrically conductive proppant from a difference between the first and second field measurements.

    摘要： Electrically-conductive sintered, substantially round and spherical particles and methods for producing such electrically-conductive sintered, substantially round and spherical particles from an alumina-containing raw material. Methods for using such electrically-conductive sintered, substantially round and spherical particles in hydraulic fracturing operations. A proppant pack comprising: a plurality of particles, each said particle, comprising a substantially uniform coating of an electrically-conductive metal having a thickness of at least 10 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 80 mesh to about 10 mesh, wherein the pack has an electrical conductivity of at least about 5 S/m, and wherein increasing a load on the pack by a factor of 2 increases the electrical conductivity of the pack by at least 50%.
