Abstract
This invention is related to the oil and gas production industry and more particularly to a proppant that can be used to enhance oil and gas production in hydraulic fracturing. Most particularly, the invention is a composition and a manufacturing process for making ceramic proppant: a ceramic matrix composition formed from a precursor of the matrix and a reinforcing additive, in which the reinforcing additive is in the form of numerous elongated inorganic crystals; or one or more than one precursor may be pre-fired (pre-calcined).
