Well intervention
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.
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 introduces an agentic artificial-intelligence framework designed for offshore production surveillance and intervention. -
The objective of this study is to field test a non-nuclear multiphase flowmeter and assess its performance under challenging operating conditions.
-
A new tubing-conveyed tool combines wellbore cleanout with multi-tracer deployment for production diagnostics and reservoir monitoring.
-
A collaboration between a large independent and a technology developer used low-cost interventions to optimize production from unconventional wells.
-
The experience captured in this paper illustrates the potential of deepwater riserless wireline subsea intervention capability and the fact that it can be expanded beyond hydraulic-only, simple mechanical, and plugging-and-abandonment scopes.
-
This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.
-
This paper describes the first riserless coiled tubing services operation performed in a live subsea well and the associated improvements in efficiency, cost savings, and safety.
-
This paper describes a case history in the UAE in which the cleanout of scale contaminated with naturally occurring radioactive material was conducted successfully.
-
Some offshore operators invest tens of millions annually in well interventions, while others spend nothing. What drives the difference remains a mystery.
-
Plugging operations are scheduled to begin early 2026.
