1. A method for monitoring, diagnosing and optimizing operation of an electric submersible pump (ESP) that comprises:

  • collecting measured data representative of a state of an ESP within a well or of well conditions, and further storing the measured data;

    matching a nodal analysis model of the well to the well by matching one or more modeled values to corresponding measured data;

    identifying one or more likely conditions of the ESP based at least in part on data generated by a matched nodal analysis model;

    updating the matched nodal analysis model to reflect a selected correction of one of the one or more likely conditions identified;

    generating a plurality of ESP performance curves using the updated matched nodal analysis model; and

    presenting to a user an action recommended to achieve an ESP performance consistent with an ESP operating point selected from one of the plurality of ESP performance curves.
