New coiled-tubing strings with consistent microstructure have twice the life of conventional strings

Over the past 15 months, Tenaris has deployed more than 100 strings of coiled tubing that were manufactured using a new process that gives the coiled tubing a consistent microstructure throughout the string. The company presented a technical paper outlining the development and field performance of the new coiled-tubing technology at the 2017 SPE/ICoTA Coiled Tubing and Well Intervention Conference in Houston. In this video from the conference on 21 March, Bruce Reichert, Chief Technology Officer for Tenaris Coiled Tubes and one of the paper’s co-authors, discusses the field performance of the new strings, which have been able to remain in use twice as long as conventional strings. He also outlines a new sour-service grade of coiled tubing developed by Tenaris.
