What you will learn
Participants will acquire a deep understanding of how the Gas Lift unloading sequence works. They will be able to connect all well parameters during the production phase. This is key knowledge to be able to troubleshoot any Gas Lift well. Students will also learn the concept of mandrel spacing design through an exercise and will be coached so that they can perform such a design themselves using a software (Prosper) to assist them. The topic of integrity in gas lift well will also be covered in detail.
Description
According to many industry experts, Gas Lift (GL) is the least understood artificial lift method, but the reason behind that is not due to its complexity. When you do things wrong on other artificial lift methods (e.g. ESP) your well will stop producing, a Gas Lift well will often keep on producing even with a bad design. Hence many operators often do not realize that their Gas Lift well is not producing at its full potential and don’t pay attention to it.
There is therefore a very significant potential for production increase by understanding the principles of Gas Lift and this is a huge career opportunity for any engineer willing to master this activation method.
This course is the 3rd of the series related to gas lift activation. It follows the courses “Forms of Gas Lift” and “Gas Lift Equipment”. It goes into detail about the Gas Lift unloading sequence (evolution of tubing and casing pressure profile, CHP, WHP and valves status during the Gas Lift well start up) with IPO and PPO valves. The problem of integrity in gas lift well will be explained as well as the existing solutions to mitigate the specific risks linked to Gas Lift. Students will be guided to make the mandrel spacing design of a well (selection of gas lift mandrels depth) so that they can understand the principles behind that choice and how to select their parameters properly (e.g. kick off pressure). The last part of the training explains how to make such a mandrel spacing design using the Prosper software. Students will be guided through the Gas Lift design new form in Prosper learning the meaning of each parameter to be filled and recommendations on the best options to select.
Curriculum
- Unloading the well basic principle
- Integrity in gas lift well
- Initial unloading following a drilling or a WO (how to empty your casing of the mud/brine without damaging your valves)
- Unloading sequence with IPO valves
- Unloading sequence with PPO valves
- Gas lift unloading principle explained by counting bubbles of gas
- Gas gradient formula and rule of thumb to quickly calculate your casing pressure at any depth
- Put it all together with an exercise (inflow/outflow/mandrel spacing design)
- Unloading sequence videos from suppliers
- Why installing a gas lift mandrel in a well portion where deviation is higher than 60°
- Gas lift system (fundamental principles, maximum rate estimation, equilibrium curve)
- Mandrel spacing design principles (where should you install your gas lift mandrels and how to do that manually)
- Temperature models
- How to choose your kick of pressure
- Guidelines to make a mandrel spacing design with Prosper (how to fill the “GL design new” form in Prosper).
Target Audience
- Production, Petroleum or Well Performance Engineers to understand how the Gas Lift unloading sequence works and how to make an SPM design
- Field Production Personnel to understand how their Gas Lift well work and respond better to the questions of their support teams in town
- Completion Engineers to understand fully the needs for mandrels in a Gas Lift well.

Very thorough gas lift course. Damien is passionate and knowledgeable.
Saurabh (verified owner) –
Extremely informative lectures. I haven’t seen such good explanation for many of the topics anywhere in the industry. Well done !
ipjuanvazquez (verified owner) –
This course was one of my favorites. It allows you to clearly know unloading sequence of a well, you will also be able to know the process to be able to design a well with GL. The step-by-step guide for Prosper is very practical and clear. The videos and PPT are really very clear and very easy to understand, it is definitely a course that you have to take.
