Abstract:
A method of installing an expandable coiled tubing portion into a surrounding tubular body within a wellbore, the method comprising the steps of:running a string of coiled tubing into the wellbore to a desired depth adjacent a tubular body, the coiled tubing having an inner surface and an outer surface, and the surrounding tubular body having an inner surface and an outer surface; expanding the string of coiled tubing at a first depth so as to engage the outer surface of a first portion of the coiled tubing with the inner surface of the surrounding tubular body at the first depth; disconnecting the string of coiled tubing from the expanded first portion of coiled tubing, thereby forming a disconnected string of coiled tubing and a first expanded coiled tubing portion; and removing the disconnected string of coiled tubing from the wellbore.
