In a well an instrumentation line can be introduced down the well bore by a control line having at least a portion outside of intermediate casing and set in cement slurry between the intermediate casing and the surrounding rock and reaching to a zone of interest. A primary member accepts the distal end of the control line at the end of the intermediate casing. A secondary member has a terminal control line (sealed at its far end) attached on its outer surface. When in place, the secondary member extends into and through the zone of interest. When the secondary member is lowered through the primary member, its top end is lowered onto the bottom end of the primary member. Couplings engage and angularly orientate so that the top of the terminal control line couples to and seals with the distal end of the control line to form a conduit through which a fibre optic instrumentation line can be threaded.

The system of claim 1, wherein the base roller is coated with tungsten on a surface, the support roller is formed from aluminum oxide-containing silicon, and the retainer roller is formed of a chrome-plated metal.
