Gas assisted plunger lift systems works much like an intermittent gas lift system, however, a conventional plunger is added to the system.
When using an intermittent gas lift system, typically less than desirable results are achieved do to the fluid fallback and the total fluid recovered per cycle. Fluid fallback in the tubing per cycle can be as much as 10% of the initial fluid slug per 1000’ of lift.
In a Gas Assisted Plunger Lift system we add a conventional plunger and fluid fallback can be significantly reduced by more of the fluid slug being delivered to surface by the plunger.
Gas Assisted Plunger Lift systems also help moderate paraffin and or scale buildup on the tubing wall by having the ability to drop the plunger periodically for cleanup runs.
