Well intervention
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.
-
This study highlights the strategic implementation of coiled tubing to convey perforating guns in extended-reach wells, overcoming the lockup effect through the deployment of downhole tractors and real-time monitoring tools. -
This study emphasizes the vital need to evaluate well conditions and working-fluid compatibility with coiled tubing materials to prolong coiled tubing operational life.
-
This paper describes the application of an underbalanced coiled tubing technology in tight sandstones, using an integrative approach that incorporates petrophysical, geophysical, and reservoir engineering data.
-
This paper addresses the challenges of integrating huge amounts of data and developing model frameworks and systematic workflows to identify opportunities for production enhancement by choosing the best candidate wells.
-
The authors challenge the traditional planning and execution of interventions, both from an operational and commercial standpoint, and examine where room exists for significant improvement in the industry
-
This paper describes how near-real-time tracer data from the onsite tracer analysis enabled the operator of the Nova field to interactively optimize two well cleanups.

Chevron has some new ideas on how to get more oil for less cost out of shale wells in their early years.
-
The authors of this paper describe a coating designed for enhanced erosion resistance for standard wire-wrapped screens that consists of ceramic or hard metal applied by plasma spraying.
-
The authors of this paper describe a project in which retrofitted autonomous inflow control devices were deployed successfully in a field to minimize water production and maximize oil recovery.
