This paper summarized influencing factors to the sensor system reliability used in Oil and Gas. A management plan based on criticalities of influencing factors to the overall system is proposed. Prediction of sensor system reliability will be especially useful in the situation where sensor systems can degrade over time in service. A modeling approach has been carried out in this paper to combine the Bayesian network modeling and 'Analytical Redundancy relations' Methodology for assessing sensor reliability in a digital downhole application.
