Abstract
The present disclosure relates to a micromesh proppant for use in hydraulic fracturing of oil and gas wells. In one embodiment, a process for forming proppant particles includes providing a slurry comprising a ceramic raw material containing alumina, atomizing the slurry into droplets, coating seeds comprising alumina with the droplets to form green pellets, sintering the green pellets to form sintered pellets, and breaking the sintered pellets to form proppant particles comprising a sintered ceramic material and having a size of from about 150 mesh to about 500 mesh and a crush strength at 7,500 psi of from about 1% to about 20%. In one embodiment, a proppant particle includes a sintered ceramic material and having a size of from about 150 mesh to about 500 mesh and a crush strength at 7,500 psi of from about 1% to about 20%.
