FIELD: oil and gas industry.
SUBSTANCE: invention is referred to oil and gas producing industry; it can be used during hydraulic fracturing of productive stratum in order to increase efficiency of hydrocarbons extraction. The proppant includes ceramic granules having open exposed porosity up to 2% and open exposed porosity within range of 2 - 20%, at that ration of the above granules with different exposed porosity in a slug during well operation is the following: wt % of granules with porosity up to 2% is 3-97, wt % of granules with porosity from 2 up to 20% is 3-97. The invention is substantiated in dependent claims.
EFFECT: improvement of proppant slug productivity and conservation during a long period notwithstanding a value of formation pressure.
