Annotation: In this research we investigated and applied some known and original methods of spectral filtering of seismic disturbances, which occur during hydraulic fracturing. They allow to control artificial interferences, which take place due to the seismic signal propagation non-linearity and resonant properties of reservoir rock.

Keywords: hydraulic fracturing, location of microseismic signals sources, frequency, frequency-time filtering
