ON-LINE COMPOSITIONAL ALLOCATION

摘要

A method and a system to provide allocation of mixed flows back to individual sources in an oil and/or gas production system. The method is independent of sub sea on-line measurements. Instead the method uses comparably inexpensive topside equipment for compositional allocation of the flows. The method comprises the use of an on-line allocation algorithm. The method is suitable where improved reliability of flow allocation back to wells and reservoirs is needed. The allocated flow may be used to calculate and estimate the remaining volumes in a reservoir.
