The drive toward autonomous oil production imposes much stricter requirements on the collection, processing, and transmission of measurement data that characterize equipment condition and the progression of the technological process. A large amount of complex equipment fitted with diverse sensors is concentrated on well pads; therefore, a pressing scientific and practical task is to provide the automated process control system (APCS) with timely and reliable information. Solving this task is complicated by the fact that measuring instruments fairly often experience metrological failure, manifested as a gradual or abrupt degradation of metrological characteristics beyond permissible limits. The danger of such a failure lies in its detection only during metrological control procedures. The paper proposes performing online diagnostics of measurement channels in real time by employing a validated model that links the controlled output variable of the facility to the influencing input parameters. As an example, diagnostics is presented for the measurement channel of a controlled electric submersible pump (cESP) based on a direct (forward) model that relates liquid and gas flow rates to the dynamic fluid level in the well, the ESP active (real) power, and the ESP intake pressure. The predictive accuracy of the resulting model is no worse than 4 %, which confirms the feasibility of its use within the well-pad APCS for operational monitoring of cESP measurement channels.
