Abstract: There are many ways to measure hydrocarbons. Measurements may be performed on liquids, gases, or multiphase fluids. Measurement may be made utilizing orifice plates, ultrasonic meters, Coriolis meters, or a host of other meter types. After the actual meter, there is secondary instrumentation involved from transmitters to flow computers and SCADA systems. With so many components to a flow measurement system, determining the root cause of measurement discrepancies becomes a forensic exercise. In any forensic exercise, the more information the Detective has the more likely they are to find the culprit. This paper describes methodologies to determine the causes of measurement discrepancies. While this paper does draw a parallel between criminal forensics and measurement forensics, it should not be interpreted that measurement discrepancies are criminal. The world of measurement is becoming more automated, and monitor systems can detect and analyze discrepancies faster than before. However, a vast majority of measurement systems are not being monitored at the highest level, and by the time discrepancies are noted, it is all hands on deck to solve the crime.
