Gas Lift Equipment

In Oil Production

About this class

According to many industry experts
Gas Lift (GL) is the least understood artificial lift method, but the reason
behind that is not its complexity. While when you do things wrong on other
artificial lift methods (e.g. ESP) your well will stop producing, a GL well
will often keep on producing even with a bad design. Hence many operators often
do not realize that their GL 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 GL and this is a huge opportunity for any
engineer willing to master this activation method.



This class is the 2nd of
the series of courses related to gas lift activation. It follows the 1st
course “Forms of GL” and will present you the different equipment used for GL
activation. While it is not possible to be exhaustive in describing existing GL
equipment, this course does contain more information that you will find in most
of the GL trainings available in the industry.



Objectives:



Participants will acquire a deep knowledge
of the available GL equipment. 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 design, to increase
their production by performing more reasoned troubleshooting and to unlock
complex well intervention situations.
