  • Patent number: 8785356
    Abstract: The invention relates to oil and gas industry, i.e. techniques for making proppants designed to be used as propping agents in oil and gas recovery by the method of formation hydraulic fracturing. A method for the production of a lightweight magnesium silicate proppant, the method comprises heat processing of a magnesium-containing component—a source of magnesium oxide, its co-grinding with a silica-containing component, pelletizing of the batch prepared, sintering and sieving of the pellets prepared, wherein the batch comprises (in terms of calcined substance), in % by weight: SiO2-6 4-72, MgO-11-18, natural impurities—remainder, wherein the heat processing is carried out at temperature not more than 1080 degrees C. A lightweight magnesium silicate proppant is characterized in that the proppant is produced by said method. At least one of the group: serpentine, brucite, caustic magnesite, talc may be used said magnesium-containing component.
