Systems and Methods for Diagnosing Operational Conditions of a Well Pumping System

A monitoring system for diagnosing operational conditions of a well pumping system, the monitoring system comprising:

• a portable monitoring apparatus including electrical equipment housed therein and configured for receiving time-series telemetry signals from a plurality of sensors coupled to a well pumping system;
• a device processor in communication with the portable monitoring apparatus;
• and
• a non-transitory computer readable medium having instructions stored thereon that, when executed by the processor, perform the following steps of an automatic diagnostic process:
• processing the received telemetry signals to generate a set of derived operational parameters, wherein the derived operational parameters comprise computed representations of system behavior not directly observable in raw telemetry signals received by the electrical equipment;
• evaluating the derived operational parameters against a plurality of predefined multi-parameter conditions to classify the well pumping system into one or more discrete operational states, the operational states representing physically meaningful system conditions;
• upon classification of an operational state, selectively invoking one or more specialized diagnostic agents, each diagnostic agent being configured to evaluate a distinct subsystem of the well pumping system;
• independently evaluating, by each invoked diagnostic agent, the received operational parameters to determine whether subsystem-specific conditions indicative of system anomalies are present, wherein each agent produces a structured intermediate diagnostic output including a detected condition identifier and an associated confidence metric;
• aggregating the structured intermediate diagnostic outputs from the invoked diagnostic agents and performing cross-agent validation to determine whether each diagnostic output is corroborated or contradicted by one or more of the other diagnostic outputs;
• and
• producing an auto-diagnosis by generating a consolidated diagnostic determination based on the intermediate diagnostic outputs as validated.
