摘要：
Sensor failure in an oil and gas production system is monitored and detected by checking the consistency of the measurements of the sensor in question using a computer-based process model with the measurements of the other sensors in the system. The present invention also generates a back-up value for a failing sensor with the process model by identifying the value that is most consistent with the measurements of the other sensors in the system.
