The course starts by presenting a review of gas lift equipment, valve operation and the unloading process.

Discussion is carried out on installation, commissioning, operation monitoring,

troubleshooting, and maintenance. Recent innovations in gas lift technology will also be

presented and discussed. After attending this course, participants will be able to identify,

diagnose, analyze, and solve gas lift problems ensuring the efficient operation of gas lift systems

and maximizing production. Well modelling software will be used to illustrate design and

troubleshooting applications while network modelling software will illustrate gas lift gas

allocation and field wide optimization techniques.

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

• Become familiar with gas lift methods, concepts of operation, and equipment
• Select the appropriate gas lift systems and equipment
• Design continuous-flow gas lift systems for new or existing wells
• Recognize the correct data required for well analysis and troubleshooting
• Analyze, diagnose, and troubleshoot the operating gas lift systems
• Increase production from their wells using gas lift technology and optimization
