Description

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

• The course will be presented using properly designed slides, some with animation and several videos on relevant issues
• Teaching methods include also calculations on related issues

The benefits from attending

• To revisit the importance of well heads and X-mas trees and to analyse all the problems that may affect well head and X-mas trees integrity and well integrity as a whole
• To understand how critical good cementations are to avoid future well heads and well integrity problems
• To understand SAP pressures, their origin and their impact on safety and well life cycle

• Develop the knowledge relationship between surface (well heads) and downhole
• Investigate leaks and identify cause of leak
• 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
