    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 particles.

    摘要： Methods and compositions using surface chemistry and internal porosity of proppant particulates to consolidate the proppant particulates are described herein. The methods can include a method of gravel packing a wellbore. The method can include mixing an activator, a thickener, a crosslinker and a plurality of resin-coated proppant particulates to provide a gravel pack fluid and introducing the gravel pack fluid into a gravel pack region of the wellbore. The method can also include consolidating at least a portion of the plurality of resin-coated proppant particulates to provide a consolidated gravel pack, wherein the consolidated gravel pack has a UCS of at least about 60 psi when formed under a pressure of about 0.01 psi to about 50 psi and a temperature of about 160° F. to about 250° F.

    摘要： Ceramic foundry media is provided. The ceramic foundry media have a size of about 80 mesh to about 10 mesh, an average largest pore size of less than about 20 microns, and a surface roughness of less than about 4 microns. The ceramic foundry media are formed by drip casting. A slurry of finely divided particles is flowed through nozzles and formed into droplets under the influence of vibration. Uniform sized, smooth surface, spherical green particles are formed. The green particles are dried and sintered to form the foundry media.
