MITIGATING FLUID POUND EFFECTS UNDER INCOMPLETE PUMP FILLAGE CONDITIONS

Abstract:

The current subject matter provides a tool and user interface for estimating a velocity at which a plunger of a rod lift pump system will impact a fluid within a well when the rod lift pump system is altered to operate under various conditions of pump fillage. In some embodiments, the estimated impact velocity can be determined using a velocity pattern characterizing a velocity and position of a plunger of a rod lift pump system operating under a condition of complete pump fillage. The estimated impact velocity can provide a user with useful insight into potential operation of the rod lift pump system when operating under various conditions of pump fillage.
