A method for inserting at least one conductor (36) into an elongated length of metal coiled tubing (34) includes the steps of placing the coiled tubing (34 ) in a substantially vertical passageway, inserting the conductor (36) into th e tubing (34), the leading end (116) of the conductor (36) including an elongated weight (118) connected to the conductor (36), which weight (118) i s heavy enough to straighten the conductor (36) enough to fall through the tubing (34), the weight (118) having essentially no stiffness so that it is flexible enough to move through bends or irregularities in the tubing (34), which has a sufficient helical pitch providing a hold-up force due to fricti on for preventing the conductor (36) from breaking, until the desired length of conductor (36) is inserted into the tubing (34), and removing the tubing (34 ) with the conductor (36) inside the tubing (34) from the passageway and windi ng the tubing (34) on a reel (60). |
