Multiphase Flow Metering: Current Trends and Future Developments

Abstract

Abstract Over the last decade the development, evaluation and use of MFM systems has been a major focus for the Oil & Gas industry worldwide. So far, many alternative metering systems have been developed, but none of them can be referred to as generally applicable or universally accurate. Both established and novel technologies suitable to measure the flow rates of gas, oil and water in a three-phase flow are reviewed and assessed within this framework. Those technologies already implemented in the various commercial meters are then evaluated in terms of operational and economical advantages or shortcomings from an operator point of view. The lessons learned about the practical reliability, accuracy and use of the available technology are discussed. As operators now realise, incorporation of MFM's is an essential step in exploiting marginal fields. A new approach to flow assurance, deep water developments, downhole/seabed separation systems and wet gas fields is foreseen. The paper suggests where the research to develop the next generation of MFM devices will be focused in order to meet the as yet unsolved problems.
