Abstract
The present invention provides systems and methods for injecting or retrieving tubewire into or out of coiled tubing. The system comprises an injector, coiled tubing coupled to the injector and a pumping mechanism. The injector is adapted to apply a force to inject or retrieve the tubewire into or out of the coiled tubing while the pump pumps fluid in the direction of the force to provide fluid drag on the tubewire. The tubewire may be bent or straightened, and may include a protuberance on its free end to assist in the injection and retrieval process. During injection, the coiled tubing may remain on a reel or may be stretched out along a surface.
