ABSTRACT:
A fiber optical or other cable is inserted through a pre-in-stalled guide conduit in a well by: installing an upper part of the guide conduit permanently in the well such that it is embedded in the annular cement body at the outer surface of a casing string between a wellhead and an outer component of a guide conduit connector which is located near a lower end of the casing string; installing a lower part of the guide conduit in the well such that it extends alongside the outer surface or is an integral part of a liner string down from an inner component of the guide conduit connector which is located near an upper end of the liner string; aligning the inner and outer components of the guide conduit connector with each other; and pumping the cable down through the thus interconnected upper and lower parts of the guide conduit.
