Gas Lift Equipment

About this class

According to many industry experts, Gas Lift is the least understood artificial lift method, but its complexity is not the reason behind its misunderstanding. Instead, the challenge behind Gas Lift is that after implementing a lousy design, the well will often keep producing, unlike other artificial lift methods (e.g., ESP) that stop producing. Thus, operators fail to recognize design or operating errors that restrain production. Therefore, there is a significant potential to increase production by oil and gas professionals who understand the Gas Lift system and its fundamental and advanced principles.

This comprehensive industry-based Gas Lift Equipment training course consists of theoretical and practical knowledge regarding all related equipment involved in gas lift production.

Through this gas lift training, participants will come away with a complete overview of gas lift technologies critical to the efficient operation of the gas lift system.

Key components like gas lift mandrels, including conventional gas lift mandrels and side pocket mandrels, will be presented. All items related to gas lift design change-out operation will be shown, like kick-over tools, running tools, pulling tools, and latches. This is critical to master Gas Lift operations. Gas lift valve mechanics and the gas lift valve calibration procedure are explained in detail with practical tips to avoid common calibration errors leading to well operating issues.

A comprehensive review of many specific gas lift valves will be performed. It will allow participants to discover solutions to specific issues that they will face in their gas lift wells. This gas lift course will introduce delegates to many new technologies (like surface-controlled electric gas lift valves or the AVT), but also very old ones forgotten by the market (like balanced valves or flexible sleeve valves).

While it is impossible to be exhaustive in describing existing Gas Lift equipment, this course contains more information than you will find in any Gas Lift training available in the industry. It is there to help you maximize the oil recovery factor through more efficient gas lift systems.

This lesson is the 2nd of a series of 5, designed to help you reach an advanced level in Gas Lift oil production and operations. The series starts with ‘Forms of Gas Lift’, and resumes with ‘Gas Lift Unloading Sequence and Mandrel Spacing Design’, ‘Gas Lift Optimization and Design with Existing Mandrels’, and ‘Gas Lift Troubleshooting’.


Participants will acquire a deep knowledge of the available Gas Lift equipment. The subject will be discussed from a well intervention, completion, as well as from a production point of view. This will allow engineers to select the right equipment for their gas lift system design, increase production by performing more reasoned troubleshooting, and unlock complex well intervention situations.
