The work purpose - application of microseismic monitoring in the process of technological actions. They are directed to intensification of hydrocarbon production, by identifying fracturing zones to control the fracturing, identifying zones of emission activity in the reservoir when injecting liquid in injection wells. A feature of this technology is the possibility of determining fracture zones using surface observation antennas, without observation wells. This distinguishes it from traditional well monitoring technologies. Also, this significantly reduces the cost of work, since there is no need to stop the wells at the time of monitoring and additionally bear the costs of lowering special equipment. This technology, in addition, has a high resolution mapping.
