Well Control in Completion, Workover, and Intervention

05 – 09 Jan. 2026, Abu Dhabi26 – 30 Oct. 2026, Dubai

COURSE OVERVIEW:

Completion, workover, and intervention operations are frequently carried out on live or partially live wells, where the risk profile for well control incidents can be significantly higher than during drilling. Activities such as perforating, tubing change-out, stimulation, coiled tubing intervention, and wireline logging may all alter the barrier envelope and expose the well to uncontrolled flow if not rigorously planned and executed.

 

This course provides a structured and practical understanding of well control principles as applied specifically to completion, workover, and intervention operations. It explains how well barriers are established, verified, and maintained; how different intervention techniques impact pressure and flow regimes; and how to plan, monitor, and execute operations safely on live wells.

 

Participants will gain detailed insight into pressure fundamentals, well control equipment, barrier philosophy, risk assessment, and emergency response. Attention is given to completion and workover fluids, kill methods, coiled tubing and wireline well control, snubbing operations, and the integration of surface and subsurface equipment. Realistic examples and case studies are used to illustrate common failure modes, lessons learned, and best practices for safe, efficient, and compliant operations.

 

COURSE OBJECTIVES:

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

  • Explain the basic principles of well control and how they apply to completion, workover, and intervention operations.
  • Distinguish well control considerations in completion and intervention from those in drilling operations.
  • Describe the well barrier philosophy, including primary and secondary barriers, and their application in live-well activities.
  • Interpret pressure regimes, hydrostatic balance, and influx mechanisms during completion and workover.
  • Identify the main well control equipment used in completion and intervention (surface and subsurface) and describe their functions.
  • Evaluate the impact of completion, workover, and intervention fluids on hydrostatic pressure and well control margins.
  • Plan and verify barrier integrity before starting completion, workover, or intervention operations.
  • Apply standard operating procedures for maintaining well control during wireline, coiled tubing, and snubbing operations.
  • Perform basic well control and volumetric calculations relevant to completions and workovers.
  • Recognise early warning signs of loss of well control and define appropriate immediate actions.
  • Develop simple kill plans suitable for completion and workover scenarios, including bullheading and circulation methods.
  • Conduct risk assessments and implement control measures for well control hazards in completion and intervention programs.
  • Coordinate well control responsibilities and communication among rig site personnel, service companies, and onshore support.
  • Analyse well control incidents and case studies from completion and intervention operations to derive lessons learned and best practices.

    TARGET AUDIENCE:

    • Completion, workover, and well intervention engineers and supervisors.
  • Drilling and well engineers are responsible for planning and oversight of well operations.
  • Coiled tubing, wireline, and snubbing engineers and field specialists.
  • Production and reservoir engineers supporting live-well intervention programs.
  • Field, operations, and rig supervisors are involved in completion and workover activities.
  • HSE professionals and technical authorities concerned with well control and integrity.

    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 who complete at least 80% of the total attendance time requirement.
