Abstract
A cable is injected into a length of coiled tubing disposed on a reel by an apparatus and method which includes attaching a small diameter pipe to the end of the coiled tubing, feeding the cable into the opposite end of the pipe through a seal and pumping a liquid into the annular space defined by the cable and the pipe at sufficient pressure and flow rate so that fluid drag on the cable overcomes the frictional force of the cable passing through the seal to inject the cable through the entire length of the coiled tubing. This method avoids the prior expensive practice of deploying coiled tubing in a straight line, either horizontally or vertically in order to feed cable through the tubing.
