FIELD: oil and gas industry.
SUBSTANCE: invention is related to proppants made from natural quartz sand and intended for use as proppants in the production of oil or gas by hydraulic fracturing. Silica proppant made from natural sand and containing 82-99% by weight of silicon dioxide, additionally contains 0.01-0.4% by weight of manganese oxide and 0.1-0.7% by weight of tungsten trioxide.
EFFECT: production of a siliceous proppant having an increased coefficient of recovery after impact.
