Abstract
Systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining an operational state of one or more solenoids of well equipment are disclosed. A characterization and diagnosis apparatus can determine characterization measurements for a solenoid. The characterization measurements can be obtained during a characterization mode of the solenoid based on drive voltages and temperatures. The characterization and diagnosis apparatus can determine sampled measurements for the solenoid during an operational diagnosis mode of the well equipment. The characterization and diagnosis apparatus can compare the characterization measurements to the sampled measurements to diagnose the operational state of the solenoid.
