Abstract:
A seismic exploration system comprising:an array of seismic receivers, each seismic receiver producing a seismic trace with the array including at least one group of seismic receivers; each seismic receiver including a set of a plurality of seismic sensors, with each seismic sensor producing a seismic signal; a controlled element, coupled to each of the seismic sensors, for modifying the seismic signal produced by each seismic sensor; at least one combining element, each combining element being coupled to an output of each of a plurality of the controlled elements coupled to one of the plurality of sets of seismic sensors for combining the seismic signals to produce at least one seismic trace or to modify which seismic signals are combined to produce each seismic trace; and a control, coupled to each controlled element, for controlling the modifying or combining of the seismic signal produced by at least one set of a plurality of seismic sensors in response to commands received by control; and a station, coupled to the seismic receivers, for collecting and recording seismic traces produced by the seismic receivers and producing and transmitting the commands to the control.
