FIELD: oil and gas industry.
SUBSTANCE: method involves process of formation hydraulic fracturing in well including recording of microseismic activity generated during hydraulic fracturing process. Also low-frequency waves of pressure (tube waves) are generated near well. Tube waves reflected from hydraulic fracturing are recorded on-line and location of microseismic events and reflection of tube waves from hydraulic fracturing is analysed.
EFFECT: increasing accuracy of determination of initial stage of splitting and accompanying phenomena during formation hydraulic fracturing.
