FIELD: oil and gas industry.
SUBSTANCE: invention relates to production of ceramic proppants intended for use as proppants when extracting oil or gas using hydraulic fracturing treatment, HFT. Use of dust wastes formed during serpentinite annealing, as reinforcing material for polymer coating applied on surface of proppant, wherein above dust wastes are added in amount 0.05-0.5 % of proppant weight. Invention is developed in depending points of the formula.
EFFECT: wider raw material base when producing proppant with reinforced coating.
