SCHLUMBERGER has unveiled the next generation of multiphase flow meters for offshore and land applications.

The company said the Vx Spectra surface multiphase flow meter enabled operators to obtain flow rate measurements in production testing and permanent monitoring.

The device uses full-spectrum analysis to accurately quantify oil, gas, and water flow rates without phase separation.

Applications span continuous production monitoring, periodic production testing, fiscal allocation, well performance evaluation, and artificial lift system optimisation in both land and offshore operations.

“A precise production allocation requires continuous and accurate flow rate measurements to better understand current and future reservoir productivity,” Schlumberger testing services president Sameh Hanna said.

“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.”

Additionally, the flow meter uses full gamma spectroscopy to provide the highest accuracy in multiphase production measurement.

According to Schlumberger, the compact nature of the Vx Spectra flow meter saved space on onshore platforms compared with conventional equipment.

Its modular design and advanced electronic components increased reliability to minimise downtime and reduce running costs as well as offering easy integration with operators’ production facilities.

The flow meter 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 barrels per day, while the 40mm venturi version introduces a mid-range multiphase meter with high flexibility to match oil and gas production flow rates.

Extensive testing was conducted to confirm the metrological performance of the Vx Spectra surface multiphase flow meter. Tests were conducted with various fluids and at different pressures and flow regimes.

The study acquired more than 400 test points at four industry reference flow loop metering facilities.
