Abstract: Event-based telemetry for artificial lift in wells is described. An example downhole system can sense triggering events and anomalies in a well or electrical submersible pump (ESP) string, and send information about the triggering event with priority to a monitoring and control system. A telemetry manager can select specific sensors to address the triggering event, and then determine how frequently the selected sensors acquire or sample sensor data. The telemetry manager may then assemble a data stream that prioritizes the sensor data for transmission on limited bandwidth, thereby sending the most important data about the triggering event with the highest priority, even when there is limited transmission bandwidth available.
