A general dynamic plunger lift model is presented which can be used to predict optimum design of a plunger lift system for wells which are producing by any reservoir mechanism. The upstroke and downstroke plunger models are coupled to a generalized inflow performance relationship thereby matching the production capability of the reservoir to the plunger dynamics. By matching reservoir performance and plunger dynamics the optimum slug size and cycle time can be determined which will maximize the liquid production for a given well.
A discussion of the development of the dynamic plunger lift model is presented and performance comparisons are made with other models available in the literature.
Conclusions are stated and potential improvements addressed concerning future work in plunger lift technology.
