Abstract
Seismic acquisition apparatus comprising a plurality of detectors (s1, s2, etc.) each constituted by one or more seismic sensors, combiner means which generate at least one seismic trace corresponding to a group of detectors by combining the signals output thereby, and memory means for storing the seismic traces generated in this way, the apparatus being characterized in that it includes seismic preprocessor means (μP1, μP2, etc.) for re-phasing the signals output by the detectors prior to the signals being combined and/or prior to accidental noise on said signals being eliminated.
Claims7
Seismic acquisition apparatus comprising a plurality of detectors (s1, s2, . . . sn where n is a finite number) including at least one seismic sensor, and storage means for storing seismic traces,
- said apparatus further including preprocessor means which receive the signals output from the detectors and combine them to generate said seismic traces which are sent to the storage means, said preprocessor means performing at least one of a re-phasing of the signals output by the detectors and a space-time filtering of said signals.
