COURSE OVERVIEW

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops.
Coiled Tubing is the process of running a reel continuous tubing into a well that is still under pressure. Coiled Tubing equipment is portable and modular although modern reels are reaching high transport weights and offers quick rig-up times. The maximum working depth of Coiled Tubing is usually determined by the amount of tubing that can be spooled onto a reel rather than the TVD. Highly deviated wells can cause problems with Coiled Tubing as, like wireline, gravity is required to keep the tubing moving down the well-bore. This can now be overcome to a certain extent with the use of downhole “tractors” which pull the coiled tubing from the bottom. Coiled Tubing can be used for a very wide range of jobs such as, Nitrogen lifting wells, clean-up operations, spotting acid at the perforations, fishing operations, spotting cement and PLT.
This course is designed to provide participants with a detailed and up-to-date overview of Coiled Tubing Operations. It covers the coiled tubing reel and well control equipment; the power packs and hydraulic systems; the transport and rig-up procedures for coiled tubing units including applications and clean-up operations and procedures; the processes and safety considerations of nitrogen lifting wells; and the methods of spotting acid at perforations.
During this interactive course, participants will learn the fishing operations, coiled tubing job design, acidizing and stimulation techniques; the coiled tubing interventions planning and the role of downhole “tractors”; the cementing and zonal isolation techniques; the PLT (production logging tool) and properties and handling of downhole fluids; the most commonly used downhole tools for specific operations; the overall operational performance; the real-time monitoring and data interpretation; the common issues of performance troubleshooting; working safely with liquid nitrogen; the general safety protocols in coiled tubing operations; the prevention and management of kick situations; and the selection and usage of appropriate personal protective equipment (PPE).
