An apparatus (2) and method is provided whereby a small diameter, single conductor wire-line (22) is combined with standard slick-line equipment to obtain "realtime" surface display of borehole logging data from well-logging tools attached to the end of wire-line (20). A helically-formed, insulated conductor (20), which coextends within the hollow space (19) of conductive tube (18) to form an annular space (21) between the insulation (23) ¢on stranded 20 gauge silver-plated copper conductor (22)! and inner wall of the tube (18) ¢1/8" outside diameter stainless steel tubing with about 0.022" wall thickness!, functionally replaces standard solid conductor wire of 1/8" diameter for lowering tools down into a wellbore and for transmitting tool-generated signals to a surface-located display unit.
