ABSTRACT:
A seismic type electrical multiconductor cable. It is made up with a predetermined length of cable, and has a number of geophone takeout connectors spaced along that length of cable. These takeouts are electrically connected to individual geophone circuits. Half go to pig-tail connected plugs at each end, and there are program circuits that may be plugged into the pig-tail plugs.
By arranging the takeouts in pairs, physically on the same conductor but electrically isolated, only half the number of conductors are needed. There are additional conductors in the cable with multi-circuit connectors at each end. The cables are symmetrical and may be laid out end-to-end. A spread of cables would be made with connection to a recording station centrally of the spread.
