Abstract:
A method for inserting coiled tubing into a subsea well extended to the surface by a riser comprising:unreeling on a surface facility a coaxially stored spoolable compliant guide and a length of coiled tubing from a storage reel; releasably attaching a tool to a first end of the coiled tubing; releasably connecting the spoolable compliant guide to the surface facility at a proximal end of the guide; releasably attaching a distal end of the spoolable compliant guide, with coiled tubing inside and tool attached, proximate an annular seal associated with a top of the riser, where a length of the guide is sufficient for the guide to achieve a compliant shape; and inserting the coiled tubing and associated tool into the well using an injector on the surface facility.
