A method for improving seismic acquisition utilizing an active ultralight seismic detection system

摘要

The present invention is a method for determining the optimal positioning of a source-gephone pair capable of acquiring seismic data, which has been the subject of previous seismic acquisition to obtain an image of its subsoil. A first step of identifying an area of interest (32); a second step of obtaining seismic data acquired during a previous earthquake acquisition of the area of interest during the time of interest; A third step of applying a partial or full demigration of seismic data to determine the location of each source-gephone pair (31, 34) involved in the image of the subsoil of the area of interest; A fourth step of obtaining a raw trace for the geophone pair position (31, 34), a fifth step of selecting at least one optimal raw trace from the raw traces, and the at least one optimal trace. Vibration source corresponding to the processing trace - said method comprising a sixth step of obtaining a geophone pair location (31, 34).
