ABSTRACT:
A seismic exploration system where a plurality of geophone locations are employed in one spread along a survey line. The recording procedure uses a roll-along switch for successively connecting a lesser number of recording channels to the geophone locations as separate records are taken without changing the spread. A signal is superimposed at one of the geophone locations. The signal is outside the useful range of seismic energy so that the particular geophone location may be identified on successive records without interfering with the recording of the seismic energy.
