Abstract
Summary
Results of microseismic surveys from the surface are presented by the example of a 700 m long horizontal wellbore drilled in a top part of structure in carbonate deposits of Zavolzhskiy horizon. These results include microseismic monitoring of the active fractures network and multistage hydraulic fracturing monitoring. Results of microseismic monitoring of multistage hydraulic fracturing are supported by data of spectral noise logging and high-sensitivity thermometry of horizontal wellbore, conducted during well completion after multistage hydraulic fracturing.
