Patent

CA 2705618

The invention relates to a method for monitoring a subsoil zone, wherein a plurality of receivers are arranged on a surface of the soil or near said surface, straight above a geological zone to be monitored, comprising the following steps: - generating a set of reference seismic data - recording seismic data by means of said receivers, - correlating the seismic data recorded (52) with the reference seismic data, - comparing each trace of the correlated data, with correlated traces located in a vicinity of said trace, in order to evaluate a similarity of each correlated trace with the adjacent correlated traces. - detecting a microseismic event occurring in the subsoil zone by analysing said similarity. This method enables real-time monitoring.
