Plunger lift in conjunction with gas lift can improve efficiency in delifiquification of unconventional gas wells. When implemented, the dual artificial lift methods can more aggressively reduce bottom-hole pressure, and increase production in wells.
Gas-Assisted Plunger Lift – Features and Benefits:
- Help maintain production on high GLR gas lift wells
- Reduce fluid fallback in both continuous and intermittent gas lift wells
- Improve efficiency of gas lift system by cutting back on required injection gas volumes
- Minimize paraffin, scale, and other deposits build up on the tubing walls
Continuous Flow Gas Lift System with a Continuous Flow (Bypass) 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.
