• Understanding fluids and pressure

By the end of this CDGA training course, participants will be able to:

• Understand and apply Principles and Procedures (P&P)
• Apply theory regarding Completion Operations Well Control

• Understand practices and equipment surrounding Coiled Tubing
• Understand practices and equipment surrounding Hydraulic Workover (Snubbing).
• Understand practices and equipment surrounding Wireline Operations
• Understand the impact and consequences of a blowout
• Know the safety barrier principles
• Understand the behavior of a producing well
• Learn the various tool used during well interventions and work-overs
• Be aware of the methods used to control well pressure
• Learn procedures and equipment used in wireline, coiled tubing, snubbing, work-over

All personnel concerned with well intervention operations (wire-line, coiled tubing, snubbing, work-over) involved in operations linked to the detection of a kick: engineers, supervisors and operators who have to supervise or carry out well intervention operations
