Abstract:
1. A method of monitoring a subsoil zone using a plurality of seismic receivers arranged on the surface or near said surface, comprising the following steps: generating a set of reference seismic data; recording seismic data using said receivers to provide recorded seismic data; correlating the recorded seismic data with the reference seismic data to provide a plurality of correlated traces; correlating a selected correlated trace corresponding to a selected seismic receiver of the plurality of seismic receivers with a sum of correlated traces corresponding to adjacent seismic receivers located in a vicinity of the selected seismic receiver, in order to evaluate a similarity of the selected correlated trace with the correlated traces corresponding to adjacent seismic receivers; and, detecting a microseismic event occurring in the subsoil zone by analyzing said similarity.
