  • Publication number: 20160084054
    Abstract: The invention provides a system and process for providing a clean, non-contaminating process, for producing fracturing of shale, limestone, sands and other geological and mining formations to release natural gas, oil and minerals within a formation. A system used in the process produces on site the energy required to induce fracturing, removing natural gas and oil, and to recycle fluids used in fracturing for additional use. Removable storage provides the necessary materials to provide fracturing, removal and processing of the fracturing liquids for addition use at one or more sites, and to provide processing, storage and transportation of the resulting natural gas and oil.
