Abstract:
A method for inserting at least one conductor into an elongated length of metal coiled tubing, comprising the steps of:(a) placing the coiled tubing in a substantially vertical passageway;(b) inserting said conductor into the tubing, the leading end of the conductor including an elongated weight connected to the conductor, which weight is heavy enough to straighten the conductor enough to fall through the tubing, the weight having essentially no stiffness so that it is flexible enough to move through bends or irregularities in the tubing;(c) allowing the conductor and weight to fall by gravity through the tubing, which has a sufficient helical pitch providing a hold-up force due to friction for preventing the conductor from breaking, until the desired length of conductor is inserted in the tubing; and(d) removing the tubing with the conductor inside the tubing from the passageway and winding the tubing on a reel.
