Slimhole and coiled tubing standards phase 1. Weld technology (January 1996). Final report, September 1994-December 1995
The reliability and understanding of coiled tubing (CT) welds is an issue of concern in the oil and gas industry. Much work has been done to understand the fatigue characteristics of the base CT material. Until recently, little work had been done to understand the fatigue life of the CT welds, which are the weakest points in the CT string. A separate project funded by a joint industry group, recently performed a large number of fatigue tests on CT welds. This separate study showed significant room for improvement in the understanding of CT welds. The GRI-supported project attempts to improve the understanding of CT weld technology and methods by analyzing failed weld samples, reviewing and recommending new CT welding procedures and reviewing alternative welding techniques which could be use for CT welding.
