ABSTRACT:
Apparatus for downhole storage of an electrical conductor within a drill string in a borehole. The conductor is stored as a coil in a flexible storage means. The apparatus is desirably used to eliminate the short lengths of cable and the associated connectors which are normally added with each new section of drill pipe added to the drill string. Because the device is flexible, it may be used in deviated drilling.
