  • Seismic sensor units
    Patent number: 6353577
    Abstract: A seismic sensor unit (10) comprises a case (12) containing electronic circuits (18, 20) that serve to digitise and digitally process the output signals of a seismic sensor element (16) inside the case (12). A first digital filtering of acquired signals can be provided at sensor unit level before the data are further fed into a seismic network and further processed.

  • Land seismic data acquisition method and seismic cable and cable spool vehicle therefor
    Patent number: 6260656
    Abstract: A method for land seismic data acquisition is provided, together with a seismic cable and a cable spool vehicle for use in the method. In performing the method, the cable spool vehicle mechanically deploys seismic cable with attached sensors according to a desired geophysical spread and at a rate dependent upon the speed of movement of the vehicle substantially without tension in the cable. The cable spool vehicle also allows mechanical pick-up of the seismic cable together with the sensors after the seismic data acquisition.
