DNV GL has initiated a joint industry project (JIP) to promote the use of multi-phase ultrasonic flow meters for wet-gas applications. Seven industry partners have committed to the JIP, but it is open for more partners. Currently, multi-phase flow meters and wet-gas flow meters are used for both topside and subsea measurements, enabling operators to improve reservoir modeling and management, optimize production, and manage flow assurance. The output of wet-gas flow meters is also used to determine sales allocation between E&P companies and the royalties payable to the host government. The technology has been used for dry-gas metering over the last decades, and the first results under wet-gas conditions are promising. However, there is no systematic approach to its use for wet gas.
