Oil and gas well drilling using coiled tubing (CT), in general, is continually increasing. Because a significant portion of this drilling activity could involve critical sour environments, the industry and regulatory bodies have recognized a lack of adequate guidelines for under-balanced drilling of wells containing hydrogen sulfide. Drilling using coiled tubing (DUCT) in critical sour wells is currently not permitted pending the development of such guidelines. The background to the developments is presented, including a review of the materials problem, and the results from a new testing method and additional laboratory specimen testing that is required to address any deficiencies or lack in essential data.
