ABSTRACT:
A method and apparatus for selectively controlling isolated distributed recorders in an Isolated Distributed Recording System. Selection and control of isolated distributed recording units comprising a seismic data gathering Isolated Distributed Recording System are effected by transmitting preselected encoded acoustic seismic signals to which the isolated distributed recorders have been preconditioned to respond by effecting a desired control action. The same encoded acoustic seismic signal may also provide the seismic data for the experiment. Each isolated distributed recorder is conditioned to respond to several encoded acoustic signals, to discriminate against noise, and/or to respond to one such encoded acoustic signal by effecting a plurality of control actions at the isolated distributed recorder. The method and apparatus of the invention, thus, provided a large number of combinations for seismic data acquisition and control to fit the requirements of seismic data gathering operations effected in accordance with common depth points methods or other seismic exploration methods.
