Description

• All components of a Wellhead and Xmas Tree, along with their installation sequence
• Investigation, mitigation and cure of SAP pressures
• Casing and tubing seals (monitoring and leak repairs)
• Different causes of SAP pressures.
• Hazards originated by faulty wellheads and their mitigation

Designed for you, if you are...

• A field services or operations foreman
• A petroleum or production engineer
• A drilling or completion engineer
• Oil field technical staff

How we build your confidence

• Visit the importance of Wellheads and Xmas Trees and analyse all the problems that may affect Wellhead and Xmas Tree integrity, as well as well integrity
• Investigate how critical good cementation is to avoid future Wellhead and well Integrity problems
• Focus on SAP pressures, their origin and their impact on safety and well life cycle

The benefits from attending

• Develop the knowledge relationship between surface (wellheads) and downhole
• Investigate leaks and identify the cause of leaks
• Determine tubing pressures (based on depth of perfs, density of fluid and BHFP)
• Investigate SAP pressures based on well pressure monitoring using 2 and 3 pen recorders
• Explain influence of corrosion models on MAASP pressures and on Well Life Cycle
