Schlumberger Introduces New Generation Surface Multiphase Flowmeter

Vx Spectra delivers accurate flow rate measurements for oil and gas production monitoring and allocation


Schlumberger announced today the release of the Vx Spectra* surface multiphase flowmeter, which is the latest generation of multiphase flowmeters for offshore and land applications. The new multiphase flowmeter enables operators to obtain flow rate measurements in production testing and permanent monitoring.

“A precise production allocation requires continuous and accurate flow rate measurements to better understand current and future reservoir productivity,” said Sameh Hanna, president, Schlumberger Testing Services. “The Vx Spectra technology delivers flow measurements in wider applications than conventional metering systems, enabling measurements in various flow conditions from heavy oil to wet gas.”

The new flowmeter uses full gamma spectroscopy to provide the highest accuracy in multiphase production measurement. The flowmeter introduces two new venturi throat sizes adapted to an extended range of flow rates. The Vx Spectra 19mm monitors low-rate producing wells down to 30 bbl/d, and the 40mm venturi version introduces a mid-range multiphase meter with high flexibility to match oil and gas production flow rates. Modular design configurations offer easy integration with operators’ production facilities.

To confirm the metrological performance of the Vx Spectra surface multiphase flowmeter, extensive testing was conducted, acquiring more than 400 test points at four industry reference flow loop metering facilities. Tests were conducted with various fluids and at different pressures and flow regimes.
