Zusammenfassung: | A method for developing or maintaining a subterranean field includes: parameterizing seismic wave records for each identified seismic event to provide a parameter describing each seismic wave record used to identify each seismic event; generating a reference seismic event data base having the identified seismic events and the parameter; calculating a similarity value for new received seismic wave records with respect to each seismic event in the reference seismic event data base using the corresponding parameter to provide a plurality of similarity values; identifying a maximum similarity value from any of the similarity values in the plurality of similarity values that meets or exceeds a similarity threshold value; identifying a new seismic event at a location of the seismic event in the reference seismic event data base corresponding to the maximum similarity value; and modifying operation of subterranean field-related equipment in response to identifying the new seismic event. |
