FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to stimulation of wells penetrating into underground beds, particularly, to well stimulation with the help of mica-type proppants at hydrofrac. Proposed method comprises the steps that follow. (a) Injection of thickened drill fluid. (b) Injection of thickened proppant suspension containing mineral plate-like particles. (c) Injection of deflecting material. (d) Reiteration of steps a-c at least three times. Note here that plate-like particles make 20-100 wt % of proppant while their depth makes 1-500 mcm.
EFFECT: efficient hydrofrac.
