ABSTRACT:
A cable system for wellbore telemetry includes a cable anchored at a subsurface location in a rotary drill string, guide assemblies for maintaining the cable in a looped configuration, and a cable gripping device for maintaining a portion of the cable in tension. Preferably the cable is provided with a novel releasable connector and latch assembly which (1) permits the cable to be electrically connected to a subsurface instrument and anchored to the drill string, (2) permits the cable to be maintained in tension, and (3) is releasable by manipulation of the cable at the surface.
