Coiled Tubing Operations & Design
Description
Coiled tubing allows work to be done in a live well with continuous pipe that can circulate fluid, carry tools and be run and pulled under pressure. It is used for clean-outs, milling, stimulation, nitrogen kick-offs, logging in horizontal wells, fishing and many other tasks, and it sits between wireline and a workover rig in both capability and cost.
This course covers the engineering and the operations. It starts with string properties, manufacture, fatigue life and derating, then covers force analysis, lock-up and buckling in deviated and horizontal wells, and hydraulics including friction pressure, nitrogen and foam. It then covers surface equipment, pressure control stacks and bottomhole assemblies, before moving to the main applications: clean-outs, milling, acidising, nitrogen lifting, logging, fishing and zonal isolation. The course closes with job design, execution, quality control and emergency and contingency procedures.
Coiled tubing is a slender pipe pushed into a well against friction. Whether it reaches the target depends on the balance between weight, friction and buckling. In a horizontal well the pipe eventually locks up, and no more force at surface moves it deeper. Predicting that limit before the job is the central design calculation, and it drives decisions on tubing size, lubricants, tractors and the use of downhole thrusters.
Fatigue is the second design issue. Every trip over the reel and gooseneck bends and straightens the pipe, and pressure inside it increases the damage. Fatigue life is tracked cycle by cycle, and a string that is not tracked correctly can fail downhole, which turns a routine job into a fishing operation with pipe in a live well.
Hydraulics limits what can be pumped. The small bore of coiled tubing produces high friction pressure, which restricts rate and sets limits on the fluids that can be used, particularly for acid placement and clean-outs where annular velocity has to carry solids to surface. Get any of these three wrong and the job either fails to reach depth, fails to clean out or damages the string. This course covers all three in the detail needed to design and supervise jobs.
By the end of this training, participants will be able to:
- Describe coiled tubing string manufacture, properties and specifications.
- Calculate and track fatigue life and apply derating for pressure and ovality.
- Perform force and buckling analysis and predict lock-up depth.
- Evaluate methods for extending reach in horizontal wells.
- Calculate circulating pressures and hydraulics, including nitrogen and foam.
- Specify surface equipment and pressure control stacks.
- Select bottomhole assemblies for the intended task.
- Design clean-out, milling, stimulation, nitrogen lift and logging jobs.
- Plan job execution, quality control and monitoring.
- Apply emergency and contingency procedures, including stuck pipe and pipe failure.
Organisations sending participants to this training will:
- Improve coiled tubing job success rates and reach in horizontal wells.
- Extend string life and avoid in-hole pipe failures.
- Improve job design quality and reduce non-productive time.
