The course will prove valuable to production and completion engineers who are involved in artificial lift selection and the design and troubleshooting of gas lift completions. This comprehensive course will give an in-depth view of the gas-lift design, operation and troubleshooting.

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

• The fundamentals of the gas-lift completion and the lift process
• Understanding inflow and well outflow performance
• How gas-lift valves work and gas-lift valve mechanics
• How to design a gas lift completion (including a hands-on manual design exercise)
• Gaslight troubleshooting and surveillance
• Gaslight allocation to multiple wells
