Spherical Ceramic Proppant for Hydraulic Fracturing of Oil or Gas Wells, and a Process for Forming Cavities in the Surface of Spherical Ceramic Proppants

摘要

The present invention relates to improved spherical ceramic proppants for fracturing oil and/or gas wells, said proppants exhibiting spherical cavities on their surfaces. The novel proppants of the invention cause an increase in the turbulence of the oil and/or gas flow that passes through the facture where they are applied, with the consequent increase in the extraction productivity of oil or gas from these wells. The invention further relates to a process for forming cavities on the surface of spherical proppants.
