METHOD FOR SEPARATING INDEPENDENT SIMULTANEOUS SOURCES

摘要

This is a method of separating simultaneous sources thatuses an inversion-type approach. Each source will preferably activated at arandom time with respect to the others. These random delays tend to makethe interference between sources incoherent while the reflections createcoherent events within a series of shots. The shot separation is performedvia a numerical inversion process that utilizes the sweeps for each shot,the start times of each shot, and the coherence of reflection eventsbetween nearby shots. This method will allow seismic surveys to be acquiredfaster and cheaper.
