METHOD OF DETERMINING HYDRAULIC FRACTURE PARAMETERS Russian patent published in 2018 - IPC E21B43/26 E21B47/06 G01V1/40 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil production and can be used in hydraulic fracturing of a formation while simultaneously monitoring geometric and hydrodynamic fracture parameters in real time. Method includes measuring distributed temperature and pressure in a well, and then calculating the geometrical parameters of the fracture based thereon. In addition, mechanical deformations of the well casing string are simultaneously measured with strain gauges placed on the outer surface of the well casing string in a predetermined order within the perforation interval, and seismic events are monitored by means of receivers placed above and below the perforation interval. Due to the real-time concurrent monitoring of the distributed physical parameters of the well and seismic events around it, the disclosed method enables to determine the azimuth, length, crack opening width, height (opening interval) of the crack in real time when applying a hydrodynamic action on a permeable reservoir, which, in combination with a geomechanical model of crack development, allows to optimally specify injection modes in order to achieve the target fracture parameters.

EFFECT: technical result consists in ensuring the possibility of determining with high accuracy geometric fracture parameters, specifically the azimuth, length, average opening width, height (opening interval) directly in the hydraulic fracturing process.
