ABSTRACT:
A method for decimating seismic traces in an acquisition of 3D data, recording, for each trace, the corresponding source-receiver couple coordinates (Sa1, Ra1), positioning on a decimation grid (D), divided into cells, the source-receiver couple that corresponds to each trace, regrouping all source-receiver couples into iso-path trace collections, where each collection regroups the traces whose seismic paths are identical or similar, organizing the traces in each iso-path collection, and selecting the first trace in each iso-path collection.
