What you will learn

Participants will acquire a deep understanding on how to troubleshoot a Gas Lift well. The Gas Lift Troubleshooting Method explained in this training has been developed by the author of the course himself and is therefore not available anywhere else in the industry.

Description

According to many industry experts Gas Lift is the least understood artificial lift method, but the reason behind that is not due to its complexity. While 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 artificial lift method.

This course is the 5th of the series related to gas lift activation. It follows the courses “Understanding the Forms of Gas Lift”, “Gas Lift Equipment”, “Gas Lift Unloading Sequence and Mandrel Spacing Design” and “Gas Lift Optimization and Design with Existing Mandrels”. It explains how to find wells that require troubleshooting. It then describes a method to properly identify the issue that the well suffers from, list the different diagnostics that can be performed to confirm the issue and proposes solutions to be implemented to solve the problem. Course then guides you across must know troubleshooting tools, methods and operations. Students will learn how nodal analysis (Quicklook function in Prosper) can help them in their diagnostic, the different methods that can be used to start a Gas Lift well, the effect of temperature on Gas Lift valve opening pressure… A large section of the training is dedicated to leaks, how to detect them (tubing casing communication tests), what survey can be done to precisely identify their depth (flowing pressure and temperature surveys, spinner, spectral noise logging tool…) and how to fix them. Several troubleshooting exercises will then be shown in order to get some practice using the presented Gas Lift Troubleshooting Method.

Pre-requisites:

Understanding of the well production mechanisms (inflow & outflow) is preferred
Knowledge of the existing forms of Gas Lift and Gas Lift equipment (especially Gas Lift valves and orifice)
Understanding of the Gas Lift unloading sequence and Gas Lift optimization
Basic knowledge on well architecture
Awareness on the oilfield terms.

Bonus:

A document from world Gas Lift expert that describes an alternative method to propose a Mandrel Spacing design (the so called 20-80 rule)
Links to an article that explains an alternative method for Mandrel Spacing design for unconventional wells
Links to a presentation of a coiled tubing Gas Lift example

    This is a very complete course, in wich you will learn how to troubleshoot GL wells. All the materials are very clear and is easy to understand it. Exercises and examples are a good tool that help you to understrand better. Definitly this is a course that you must take it. 100% recommendable

    Great Value, an excellent unification of theory and practice!

    Firstly, the course was detailed, effectively merging GL theory with practical techniques that can be immediately deployed in the field by engineers and technicians. Elements of the training that I found tremendously valuable, i) The troubleshooting chart & symptom table – systematic and easy to follow, ii) The many examples/exercises incorporated – aided in conveying the key concepts/procedures, ii) Detailing of the various tools available to assist in troubleshooting & the applicability of each Secondly, I highly advise future students to follow the guidelines given by Damien at the beginning of section 1 for completing the training. I admit, that I did not adhere to these recommendations and took very long to complete course. So, set aside a specific amount of time per week for the training, and stick to the schedule, if not I guarantee something else will demand your time. Great course – highly recommended!
