Just as there are two types of gas lift systems, there are two ways to combine gas lift and plunger lift for custom artificial lift solutions.
Continuous Flow Gas Lift System with a Continuous Flow Plunger
There are several reasons/scenarios why you should consider a continuous flow plunger introduced to a continuous flow gas lift system:
+ To lift fluids more efficiently than a standalone gas lift system
+ To mitigate or eliminate paraffin or scale build up in the tubing
+To reduce the required gas lift injection volumes on single well sites or field gas lift systems thereby saving on compression costs or possibly eliminating compression
Intermittent Gas Lift System with a Conventional Plunger Lift System
An intermittent gas lift system by itself can prove to produce less than desirable results in deeper wells, strictly due to the liquid fallback and the total liquid recovered per cycle. Liquid fallback in the tubing per cycle can be as much as 10% of the initial liquid slug per 1000’ of lift. With the addition of a conventional plunger, liquid fallback can be significantly reduced and more of the slug is delivered to the surface each cycle.
