Spherical pellets containing common clay particulate material useful as a proppant in hydraulic fracturing of oil and gas wells
Abstract:
A ceramic propping agent, in the form of a spherical pellet, and containing common mineral particulate. The desired propping agent is defined as a particulate ceramic made from raw materials which may be comprised of about: 10%-90% parts by weight of a naturally occurring mineral particulate, 30%-70% parts by weight aluminosilicate network modifier, 0.25-20% parts by weight strength enhancer, and at least one part, typically less than 10% by weight, binder. For use in oil and/or natural gas wells as a hydraulic fracturing proppant.
