Xmas Trees and Well Heads are essential components of any oil and gas well. They regulate the pressures within the casings and production tubing, control production rates, and serve as vital barriers in the event of leaks.
This 4-day intensive training course on Xmas Trees and Well Heads Operation and Testing will cover:
- The various components of a Well Head and Xmas Tree, along with the installation process
- Methods for investigating, mitigating, and resolving SAP pressures
- Monitoring and repairing casing and tubing seals (including leak management)
- Identifying the different causes of SAP pressures
- Understanding the hazards associated with faulty wellheads and how to mitigate them
The main objectives of this Energy training course are to: (1) emphasize the significance of Well Heads and Xmas Trees, and examine the potential issues that may compromise their integrity, as well as overall well integrity; (2) highlight the importance of proper cementing to prevent future issues with Well Heads and well integrity; and (3) gain a clear understanding of SAP pressures, their origins, and their impact on safety and the well life cycle.
By the end of this Xmas Trees and Well Heads Operation and Testing training course, participants will be able to:
- Establish the connection between surface equipment (Well Heads) and downhole operations
- Investigate leaks and identify their root causes
- Calculate tubing pressures based on factors such as perforation depth, fluid density, and bottom hole flow pressure (BHFP)
- Analyze SAP pressures using well pressure monitoring techniques with 2-pen and 3-pen recorders
- Explain how corrosion models affect MAASP pressures and influence the overall well life cycle
This Energy training course will be presented using properly designed slides, some with animation and several videos on relevant issues. A printed manual containing all the slides and/or electronic from in PDF will be delivered to each attendant. Teaching methods include also calculations on related issues.
