1. A method performed by one or more processors for monitoring, diagnosing and optimizing operation of a gas lift (GL) system that comprises:

  • collecting measured data representative of a state of the GL system within a well, and further storing the measured data;

    comparing the measured data to calculated data generated by a well model;

    identifying, by the one or more processors, one or more likely conditions of the GL system based at least in part on mismatches between the measured data and the calculated data;

    selecting, by a user, corrections to the one or more likely conditions causing the mismatches;

    updating the well model to reflect the corrections to the one or more likely conditions;

    generating a plurality of GL system performance curves using the updated well model;

    selecting, by the user, a GL system operating point on at least one of the generated plurality of GL system performance curves using the updated well model;

    generating, by the one or more processors, one or more actions recommended to achieve a GL system performance consistent with the user selected GL system operating point;

    presenting to the user, via a display, the one or more actions recommended;

    accepting a user selection of one of the displayed one or more actions recommended to achieve the GL system performance consistent with the user selected GL system operating point; and

    triggering a system command that automatically changes a setting of a GL choke of the GL system in response to the accepting of the user selection of the one of the displayed one or more actions recommended.
