WELL OPERATION STIMULATION Russian patent published in 2015 - IPC E21B43/267 

FIELD: oil and gas industry.

SUBSTANCE: in the method of well operation stimulation including test injection of breakdown fluid and package of breakdown fluid with proppant, correction of the breakdown project and performance of fracturing in low-permeable reservoirs having absolute permeability less than 1mD, hydraulic fracturing is made with injection of flush fluid on the basis of 1.0-3.0 m³ per 1 t of proppant using proppant fractions, which include only fine fraction with size less than 30/60 mesh with final concentration of proppant less than 300 kg/m³; at injection of the fluid flow rate of 3.5 m³/min and more and concentration of gel formation is set less than 2 kg/m³, with final underflush of the mixture in volume of 0.1-0.5 m³.

EFFECT: simulation of the well opening the low-permeable formation.
