1. A method of real-time utilization of performance data by a processor, which is associated with a pump lifting well fluids of known physical properties above a liquid level in a casing of a subterranean well through a tube to a surface level, the pump having a chamber with a fluid inlet located below the liquid level that is gated by a stationary valve, and having a plunger slidably engaged with the chamber, the plunger having a known area and having a fluid outlet gated by a traveling valve that is coupled to deliver well fluids to the tube, the plunger reciprocated to vary the displacement of the chamber by a rod extending upward to a cyclical drive unit at the surface, the method comprising the steps of:

  • obtaining, in real time, a sequence of rod position data samples and rod load data samples corresponding to cyclical operation of said rod at the surface level;

    calculating, in real time, a sequence of plunger position data points and plunger load data points corresponding to cyclical operation of the rod at the plunger level, and calculated in accordance with a set of structural data for the subterranean well;

    determining a discharge pressure at the fluid outlet from the pump;

    calculating, in real-time, a sequence of pump chamber pressure data points according to said sequence of plunger load data points, anddisplaying, in real time, a portion of said sequence of plunger position data points, a portion of said sequence of plunger rod load data points, and a portion of said sequence of chamber pressure data points.
