Abstract
Coiled tubing with secured wireline and a method for manufacturing same. A slickline held by a retainer is introduced to the coiled tubing manufacturing process by attaching the retainer and slickline to a metal plate, prior to the metal plate being welded into a tubular. The slickline is unaffected by the welding and heat treatment process or processes. To install wireline into the coiled tubing, the coiled tubing is unrolled from the reel, the wireline is attached to and end of the slickline and the other end of the slickline pulled to fish the wireline through the coiled tubing, resulting in wireline held within the retainer inside the coiled tubing. Alternatively, heat resistant wireline may be secured within the coiled tubing by attachment to the coiled tubing or held by a retainer.
