Coiled Tubing Applications
The coiled-tubing industry is adapting to the changing environment. The next 12 months could bring greater or lesser volatility but the coiled-tubing industry’s record last year indicates that it will still be moving forward.
Focus on Ancillary Equipment and Fatigue in Coiled-Tubing Deepwater Commissioning
The installation of flowlines in ever-deeper and -more-remote areas requires specific technologies for precommissioning. Coiled tubing can be a solution, but long durations may affect tubing stress and fatigue.
Core Drilling Using Coiled Tubing From a Riserless Light-Well-Intervention Vessel
This paper details the planning, design, and execution of a project involving the core drilling of three wellbores using coiled-tubing directional drilling along the future Rogfast tunnel route on the Norwegian coast.
Optimization of Single-Trip Milling Using Large-Diameter Coiled Tubing
Larger-diameter coiled tubing recently has been used to perform millouts because of its improved set-down force and increased annular velocities for cleanout purposes. Service companies and operators have reduced the number of wiper trips when using larger-diameter CT, to save time and money.
Biocide Treatment Program Reduces Premature Coiled Tubing Failures
A study done to find the root cause of coiled tubing string failures in Montney indicated microbial-induced corrosion, leading the CT service provider to create a biocide treatment program.
Miniaturized Coiled-Tubing System Reduces Costs During Pipeline Decommissioning
This paper presents the challenges and obstacles faced in the use of a new technology for the plugging and deoiling of sections of unpiggable flowlines before decommissioning.
