Well intervention
This paper presents a novel approach to overcoming extended-reach limitations in coiled tubing interventions by using a split-string system, demonstrating measurable improvements in reach and operational speed in laterals exceeding 3 miles.
This paper describes the successful deployment of flexible coiled tubing technology in an oil-producing well of the offshore Frade field in Brazil’s Campos Basin.
This paper details a trial involving the deployment of a transportable coiled tubing (CT) unit capable of holding 30,000 ft of high-strength 2⅞-in. CT.

Intervention and workover operations can significantly affect the structural integrity and fatigue life of subsea-wellhead systems. Methodologies for wellhead-fatigue analysis have improved, but have yet to account for thermal effects along the well. This study analyzes those thermal effects.
