1. A method, comprising:
- receiving position data characterizing a position of a plunger over time, the plunger forming part of a rod lift pump system, the position measured by a first sensor, the plunger being configured to travel between a first position and a second position within a barrel within a well, and a distance between the first position and the second position defining a stroke length;
receiving load data characterizing a load on a rod over time, the load measured by a second sensor, the rod coupled to the plunger;
receiving velocity data characterizing a velocity of the plunger while the rod lift pump system is operating under a condition of complete pump fillage, wherein a portion of the barrel between the first position and the second position is filled with liquid prior to a downstroke of the plunger;
correlating, using at least the received load data and position data, the load on the rod and the position of the plunger; and
displaying, on a graphical interface display space, a visualization of the velocity data simultaneously with a visualization of the correlated load and position.

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.
