Couse description

This five-day (5) training course covers conventional CT workover and completion application including CT drilling technology and coiled-tubing drilling hydraulics. It presents coiled tubing (CT) as a tool for workover, drilling, and completion services. It provides an overview of the properties of CT (mechanical performance of CT, including working limits, buckling, and fatigue), its manufacture, the surface equipment utilized for deployment, and subsurface tools for CT applications.

Coiled Tubing Operations

Coiled tubing is chosen over conventional straight tubing because conventional tubing has to be screwed together. Additionally, coiled tubing does not require a workover rig. Because coiled tubing is inserted into the well while production is ongoing, it is also a cost-effective choice and can be used on high-pressure wells.

There are a number of well intervention operations that can be achieved via coiled tubing. These include cleanout and perforating the wellbore, as well as retrieving and replacing damaged equipment. Additionally, coil tubing drilling is now implemented in niche-areas and in particular in association with underbalanced drilling.

Advances in coiled tubing allow for real-time downhole measurements that can be used in logging operations and wellbore treatments. Hydraulic and acid fracturing, can also be performed using coiled tubing. Furthermore, sand control and cementing operations can also be performed via coiled tubing.

course methodology

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
