摘要：The invention relates to a process for two separate seismic crews to work inproximity to one another that would otherwise require expensive time sharing where onecrew is a conventional seismic acquisition system and the other is a phase encoded seismicacquisition system. Typically, each recording system would receive seismic energy fromthe other that neither data set would be very useful. The invention primarily envisionssome collaboration between the crews where each adjusts its sweeps to comprise adifferent time duration so that the energy the other crew's sources are distinguishable inthe data set and easily eliminated therefrom. Distinctions may be further enhanced whenthe two crews use construct their sweeps so that each crew has a distinctly different startfrequency and a distinctly different end frequency.
