About the course
Coiled Tubing is one of the most common technologies used for well Intervention on a daily basis throughout the oil industry. Its advantages and versatility make the use of the technology possible during the drilling, completion, and production phases of oil and gas wells around the world.

This course provides a comprehensive overview of the surface and pressure control equipment, as well as bottomhole assembly components used in a wide variety of coiled tubing applications, progressing from basic to complex interventions. Pumping and mechanical operations are also covered in detail, as well as drilling operations using coiled tubing, and how to prevent and deal with the negative effects of corrosion. Participants will learn how to estimate the operating limits and life of a coiled tubing string, how to do proper string management, and how to prepare appropriate checklists for job planning, equipment mobilization and rig up.

A brief discussion about nitrogen use and how to calculate required volumes is included, as well as extensive coverage of emergency responses and contingencies to deal with a wide variety of situations and scenarios. A generous amount of time is spent in practical exercises throughout the session, and technical concepts introduced by the instructor are enhanced with pictures, videos and numerous real field cases and problems.

By the end of the course participants will have gained the knowledge to actively and efficiently participate in actual job intervention operations, while minimizing the associated operational risks and maximizing the benefits of the application of the technology and the economics of the project.
Designed For
Drilling and completion engineers, production engineers, surface/subsurface engineers, operations engineers and service company managers, field engineers, supervisors and operators and those professionals willing to expand their knowledge in coiled tubing and nitrogen interventions planning, design and/or execution.
