  • Method of multi-stage fracturing of subterranean formation and slurry for that method
    Patent number: 12227698
    Abstract: A method of hydraulic fracturing of a subterranean formation having a well bore includes steps of sequentially injecting different slurries with nano, micro and then macro sized proppants generated from coal ash into the well bore in order to enhance oil and gas production from fracking. A slurry useful in the method includes (a) water, (b) coal combustion fly ash particles that have a mean particle size (d50) of about 6 microns and (c) a surfactant.
