FIELD: manufacturing technology.
SUBSTANCE: invention relates to propping fillers and methods of their production. Described are multiple ceramic proppants, where the fillers are monodispersed with the distribution, which is a distribution of 3-sigma or lower with the total distribution width of 5 % or less of the average particle size, as well as other versions of the said fillers, methods of making those proppants and methods of using the said proppants in extraction of hydrocarbons. Invention is developed in depending points of the formula.
EFFECT: higher degree of monodispersity of the propping agent, efficiency of its production, higher efficiency of hydraulic fracturing using the said fillers.
