Abstract: A selection of a hydrocarbon well of a hydrocarbon production system is received at a safety logic solver (SLS) for proof testing. Test mode pressure sensors attached to a common header of the hydrocarbon production system are activated to monitor a live process condition status of the common header from all wells of the hydrocarbon production system. A simulated overpressure condition is induced in the operation pressure sensors. An indication of overpressure is received at the SLS from at least two operation pressure sensors. Final elements associated with the hydrocarbon well are signaled to close while leaving other wells in the hydrocarbon production system in operation. The operation pressure sensors are restored to a normal pressure condition, and the final elements associated with the selected hydrocarbon well are signaled to re-open the hydrocarbon well.

Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.
