  • METHOD OF MULTI-STAGE FRACTURING OF SUBTERRANEAN FORMATION AND SLURRY FOR THAT METHOD
    Publication number: 20230257646
    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.

  • CONCRETE FORMULATION FOR SEALING AND PLUGGING OIL OR GAS WELLS FOR ABANDONMENT
    Publication number: 20230146738
    Abstract: An improved oil or gas well cement for penetrating, sealing and plugging wells to be abandoned. The cement fill includes (a) a cement component including a calcium sulfoaluminate cement and a Portland cement having a ratio by weight of Portland cement to calcium sulfoaluminate cement ranging from 1/19 to ? and (b) an aggregate component with gradation spanning 1,200 microns to 5 microns. Further an improved oil or gas well microcellular cement for penetrating sealing and completely filling wells to be abandoned that includes (a) a cement component including a calcium sulfoaluminate cement and a Portland cement having a ratio by weight of Portland cement to calcium sulfoaluminate cement ranging from 1/19 to ? and (b) an aggregate component with gradation spanning 200 microns to 5 microns and (c) a foaming agent.
