  • Hydraulic fracturing proppants Wikipedia

    A proppant is a solid material, typically sand, treated sand or manmade ceramic materials, designed to keep an induced hydraulic fracture open, during or following a fracturing treatment. It is added to a fracking fluid which may vary in composition depending on the type of fracturing used, and can be gel, foam or slickwater–based. In addition, there may be unconventional fracking fluids.
