ABSTRACT:
A method is disclosed for installing and retaining a conductor between a surface terminal and a subsurface location in a drill string used to drill a well. One end of the conductor is lowered into the drill string and is anchored to the drill string of a subsurface location. The upper end of the conductor is taken in from the surface until the conductor is tensioned to a selected amount. The upper end of the conductor is then connected to the surface terminal. As each drill pipe section is added to the drill string to advance the depth of the well, the tension of the conductor is controlled to reduce fatigue failure of the conductor. In one embodiment of the invention, the tension of the conductor is controlled by connecting a conductor section of a selected length between the surface terminal and the upper end of the conductor.
