This course covers the design, operation, diagnosis and optimisation of gas lift systems including a review of gas lift equipment, valve operation and the unloading process. You will gain an appreciation of the key concepts involved in the application of gas lift methods and a practical understanding of their operation and optimisation. 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 optimisation techniques.

About this course
The objectives of the course will be to enable participants to:
• Become familiar with gas lift methods, concepts of operation and equipment
• Perform gas lift design procedures for new or existing wells
• Recognise the correct data required for well analysis and troubleshooting
• Diagnose and troubleshoot gas lift well performance
• Optimise the gas lift system for production and long term reliability
This course is designed for you, if you are petroleum engineering or field staff involved in the selection, design, operation or troubleshooting of gas lift systems.
This course ensures that fundamental concepts of gas lift systems are well explained and clearly understood before progressing to more advanced topics such as design and optimisation. This technique means that participants have a solid foundation to build a deep understanding of gas lift systems and the confidence to apply the principles learned.
We look forward to hearing from you and endeavour to respond to your inquiry as quickly as possible!

Gas lift systems diagnosis, practical troubleshooting and optimisation
- Gas lift operations, monitoring and procedure for unloading a new well
- Gas lift diagnosis and troubleshooting; key concepts and procedure for analysis
- Flowing gradient survey interpretation and matching; determination of injection depth, orifice pressure drop, etc.

- Re-design of a gas lift valve setting for an existing well to address these problems
- Practical workshop session; gas lift well re-design using existing mandrels with field data
- Introduction to surface network modelling; well performance curves, interactions between wells and pipelines
- Shortage of gas supply; gas-lift allocation concepts & multi-well optimisation techniques
- Practical workshop session; building a wellhead platform model with field data
- Matching field performance and running gas lift gas allocation sensitivities
- Review, conclusions and evaluation form completion
Note:
Each day will include practical workshop sessions illustrating the application of theory to gas-lift well models. Participants are encouraged to bring field data and examples to interpret and analyse.
Workshop / In-House Presentations:
During the 4-day session the instructor would aim to use client’s well data throughout and participants should be able to build, validate and diagnose their own wells. So each day will include practical workshop exercises using commercial software (either Prosper from Petroleum Experts or WellFlo from Weatherford).
The course is designed to be highly interactive and the instructor is always open to answering questions as they arise.
