Abstract

Well-known and original methods of spectral filtering of the seismic noise occurring in hydraulic fracturing have been studied and applied. They allow control of artificial noise and natural interference due to the nonlinear propagation of seismic signals and the resonance properties of the reservoir rock. Original spatial filtering is applied to eliminate the redundancy of location data. A threedimensional model for the reservoir fracture zone formed by hydraulic fracturing is proposed.
