Abstract

Methods and apparatus for deploying a line in a borehole using coiled tubing are presented. Methods are applicable for use in deploying a line in a coiled tubing when the coiled tubing is spooled on a reel or deployed in a wellbore. A line reel provided in a pressure housing is used to supply a line for deployment using fluid flow in coiled tubing. The line reel assembly and deployments methods are suitable for use under well pressure. The line may comprise fiber optics. Subsequent to deployment of coiled tubing with a line dispose therein, the coiled tubing may be withdrawn, leaving the line in the wellbore.
