Accurate measurement of the output of wet gas fields is an important means of reducing the financial risks that Exploration & Production (E&P) companies face in sales gas allocation. Ultrasonic flow meter technology is proven for dry gas metering and E&P companies now hope to apply it to wet gas. DNV GL has therefore initiated a Joint Industry Project (JIP) to build a solid foundation to facilitate the wide acceptance of this technology for use in wet gas sales allocation. Seven industry partners have committed to the JIP, but it is open for more partners.
Currently, multiphase flow meters and wet gas flow meters are used for both topside and subsea measurements. They enable operators to improve reservoir modelling and management, optimise 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.
