ABSTRACT:
Coiled tubing for weld purposes is provided with a conduit which can be connected to a power source at one end and to a power device intended to be lowered into the well at the other. The tubing is filled with a low viscosity composition which is then set to a high viscosity state to anchor the conduit to the inner wall of the tubing and thereby hold the conduit in place so that the coiled tubing will not suffer from the capstan effect.
