More Information
Summary:The invention concerns a passive monitoring method to detect the presence of and characterize a micro-seismic event (3) occurring in the subsurface, by processing seismic data recorded by a plurality of seismic receivers (R1, Rn) arranged on the earth surface (4), said seismic data comprising acquisition noise and a wave field (6) generated by the micro-seismic event, said wave field being drowned in the noise, the method comprising the performing of waveform inversion directly on the seismic data recorded by the seismic receivers with no prior detection of the wave field generated by the micro-seismic event.
