Abstract
A method for optimizing production from a rod-pumping system includes the steps of providing a well having a rod-pumping system for pumping a fluid from a downhole location of the well to a surface location of the well; providing a mathematical model for determining a dynagraph relationship for the well from power consumption of the rod pumping system; measuring power consumption per cycle of the rod pumping system; determining a downhole dynagraph relationship from the power consumption per cycle and the model; measuring real time values of wellhead pressure and preferably wellhead temperature; and determining an optimum operating condition for the rod-pumping system from the downhole dynagraph relationship and the real time values.
