METHOD OF CONDUCTING LOCAL DIRECTED HYDRO BREAK OF BED Russian patent published in 2008 - IPC E21B43/26 

FIELD: mining.

SUBSTANCE: method includes detection of strained zones in reservoir-bed of uncased hole by means of seismic sounding with method of scattered waves and boring of side parallel bore holes of smaller diameter along axis of main forces of compression of massif. At that the distance between the parallel horizontal bore holes is chosen on base of condition of facilitating their stability and possibility to conduct vertical hydro break along the length of horizontal bore holes when ruptures move towards each other, merge and are involved into development of oil pillars, of its blind end and dead zones in a bed with bottom water or in a bed with above or below bottom water.

EFFECT: upgraded efficiency of method due to possibility to facilitate uniform along the whole length vertical or horizontal rupture.
