surface at the granulation stage between the growth stage and the powdering stage a coating with the melting point below the sintering temperature of the main granule can be deposited on the semi finished granules this easy melting layer keeps tightly the roughness making particulate on the surface of the ready granules the same goal can be achieved by applying of powdering agent with the melting temperature below the melting temperature of the granule body in yet another respect the proppant manufacturing method includes additional stage between firing and fractional classification proppant particle are mixed with ceramic polymeric metallic glass cement materials and compositions thereof these materials may be in the form of powder granules fibers or combinations thereof or various agglomerates of ceramic polymeric metallic glass cement powders and or fibers and also their combinations these materials stick to the proppant and create at least one type of roughness and irregularities described by formulas 1 and 2 and depicted in the figure thereby the amount of material added at the intermediate stage is calculated on the basis of the average number of irregularities upon 1 mm 2 of proppant surface the average height of irregularities and proppant diameter for spheroids the produced proppant is used by the standard technology of hydraulic fracturing in particular the advantage of the developed proppant was tested at a well cluster i e under identical conditions 1 the hydrofracturing was carried out in the west siberia oilfields at the depth of 3700 m under typical conditions with the expected productivity of 80 140 m 3 per day the pumping of traditional spherical ceramic proppant smooth surface resulted in the well production rate 90 m 3 per day 2 under the same conditions and same proppant composition but with artificially rough surface.
