Abstract: Cutting elements for earth-boring applications may include a substrate and a polycrystalline diamond material secured to the substrate. A first region of the polycrystalline diamond material may exhibit a first volume percentage of nanoparticles bonded to diamond grains within the first region. A second region of the polycrystalline diamond material adjacent to the first region may exhibit a second, different volume percentage of nanoparticles bonded to diamond grains within the second region. Methods of making cutting elements for earth-boring applications may involve positioning a first mixture of particles having a first volume percentage of nanoparticles and a second mixture of particles having a second, different volume percentage of nanoparticles within a container. The first and second mixtures of particles may be sintered in the presence of a catalyst material to form a polycrystalline diamond material including intergranular bonds among diamond grains and nanoparticles of the polycrystalline diamond material.

Abstract: Fracturing slurries are prepared on the fly using a solids pump to feed the solid such as a gel into a liquid stream of normally water for pumping downhole with a large capacity triplex pump. The solids pump is preferably a Posimetric® style which delivers the solid into the fluid pipeline in a manner that keeps fluid from backing into the solids hopper above the solids pump. A separate fluid tank is connected to a fluid pump to pressurize a suction line to a boost pump before reaching the triplex pump and pumping into the subterranean formation. The solids pump can deliver between the fluid and boost pumps in which case the solids go through the triplex pump or alternatively the solids can be delivered into the higher pressure discharge line of the triplex pump.
