NOV develops 140-ksi, sour gas-resistant coiled tubing

screen-shot-2017-03-28-at-11-07-43-am

National Oilwell Varco (NOV) recently developed 140-ksi specified minimum yield strength (SMYS) coiled tubing, or CT140. Because the target market for high-strength tubing is high-pressure well intervention and completions, sour gas compatibility testing was performed. The testing program verified that while using chemical inhibitors, the tubing/inhibitor system was not susceptible to sulfide stress cracking. In this video from the 2017 SPE/ICoTA Coiled Tubing and Well Intervention Conference in Houston on 21 March, Kevin Elliot, NOV Product Engineering Manager, discusses the development process that was undertaken, as well as the resulting mechanical properties and fatigue life of CT140. For more information about this project, please see SPE 184806, “Development and Compatibility Testing of Coiled Tubing With 140-ksi Specified Minimum Yield Strength.”

First oil flows from the Flyndre field

first-oil-flyndre

Production has begun from the Maersk Oil-operated Flyndre field in the UK and Norwegian North Sea. First oil began to flow on 26 March, traveling 25 km via pipeline to the Repsol Sinopec-operated Clyde platform. Production from the Flyndre field is expected to peak at 10,000 barrels of oil per day, with the field expected to produce until at least 2023. As well as today’s new production, Maersk Oil continues to focus on the North Sea region, where it is delivering value from a substantial producing asset base and major new developments such as the Maersk Oil-operated Culzean field on the UK Continental Shelf and the company’s stake in Norway’s Statoil-operated Johan Sverdrup field. Gretchen Watkins, Maersk Oil CEO, said, ...
