COURSE OVERVIEW:

Well Intervention and Coiled Tubing Operations is a comprehensive program designed to provide engineers and supervisors with the technical expertise required to manage rigless well entries. As wells mature, interventions become necessary to maintain or restore production, manage solids, or repair downhole equipment. This course focuses on the most versatile intervention tool—Coiled Tubing (CT) and explores its application in cleaning, stimulating, and logging live wells.

The scope of this training includes the mechanical limits of the CT string, the physics of tubing forces (buckling and fatigue), and the operation of the surface injection system. Participants will learn how to design CT programs for various objectives, such as nitrogen lifting, scale removal, and localized acidizing. The curriculum emphasizes the critical importance of well control during intervention, covering the operation of the CT BOP, strippers, and riser systems.

Coverage also extends to the fluids and chemicals used during CT operations. Attendees will explore the rheology of clean-out fluids, the use of friction reducers, and the mechanics of "low-state" completions. By focusing on both the surface hardware and the downhole dynamics, this course ensures that participants can execute complex interventions safely, minimize the risk of stuck pipe, and maximize the return on investment for well maintenance projects.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the primary applications and limitations of Coiled Tubing (CT) in well intervention.
• Identify and explain the function of the CT surface equipment (Reel, Injector, Power Pack).
• Analyze CT mechanical limits including internal pressure, collapse, and cycle fatigue.
• Calculate tubing forces and identify the onset of helical and sinusoidal buckling.
• Design effective wellbore clean-out programs using specialized nozzles and fluids.
• Manage nitrogen lifting operations to revitalize "dead" wells.
• Execute chemical stimulation (acidizing) through CT for precision placement.
• Select appropriate Bottom Hole Assemblies (BHA) for milling and fishing.
• Operate CT well control equipment including BOPs and stripper elements.
• Troubleshoot common CT operational issues such as stuck pipe or tubing leaks.
• Perform "Life-of-Pipe" tracking and manage fatigue accumulation.
• Evaluate the benefits of CT-conveyed logging and perforating.
• Implement best practices for CT rig-up, testing, and rig-down.

TARGET AUDIENCE:

Well Intervention Engineers, Production Engineers, Field Supervisors, and Technical Specialists involved in rigless well operations.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
