Microseismic Monitoring of Multistage Hydraulic Fracturing in Horizontal Wells

The most reliable way to map systems of fractures formed as a result of hydraulic fracturing in the reservoir is microseismic monitoring. At first this is important for horizontal wells. Induced fractures often have a complex structure, this makes modeling a very difficult task, even with presence of high quality geological and hydrodynamic flow models. Simulation problems in turn leads to low efficiency of the fracturing with significant time and money losses. Presented the results of monitoring of the 7 fracturing stages in the Orenburg region in 2014, and showed the importance of a comprehensive study of the fractured space structure for a successful and effective development of the oilfield
