METHOD OF INTENSIFICATION OF OPERATION OF WELL Russian patent published in 2015 - IPC E21B43/267 

FIELD: mining.

SUBSTANCE: method comprises a test injection of fracturing fluid and a pack of fracturing fluid with proppant, correction of the fracturing project and carrying out the main fracturing process. At that in the high-permeability reservoirs having an absolute permeability of not less than 100 mD, the main process of hydraulic fracturing is carried out using standard working fluid flow rate of 2.2 m³/min to 4.0 m³/min. When pressing the proppant-gel mixture the stepwise reduction of flow rate is carried out with the reduction step in the range of 0.1 m³/min to 0.5 m³/min, but to the value of not less than 2.0 m³/min. The final concentration of proppant is set of not less than 800 kg/m³.

EFFECT: increase in efficiency of intensification of operation of the well by creating a wider and conducting crack in the bottom-hole area of the layer.
