Surface multiphase flowmeter

Vx Spectra surface multiphase flowmeter for accurate flow rate measurement and improved production testing

Vx Spectra Surface Multiphase Flowmeter

Continuous multiphase flow metering in all well conditions

The Vx Spectra™ surface multiphase flowmeter (MPFM) is our flagship SLB MPFM based on rugged Vx™ multiphase well testing technology. The Vx Spectra flowmeter delivers continuous, accurate, and repeatable measurements in a wide range of production environments—all the way to high-rate oil and wet gas wells. Using advanced full-gamma spectroscopy, our surface multiphase flowmeter accurately captures multiphase flow dynamics, so you can determine flow rates without the need for separation and get full visibility on your well performance.

Increased accuracy in high-GVF, high-water-cut, and unconventional wells

The latest development in the Vx Spectra flowmeter portfolio features an innovative high-energy source design that can be retrofitted to any existing Vx Spectra flowmeter to significantly improve accuracy at high gas volume fraction (GVF). The introduction of this triple-energy source markedly improves the distinction between oil and water fractions, therefore reducing the error in water cut and consequently oil/water rates.

This modification enables a significant improvement in both liquid rates and water/liquid ratio at GVF greater than 95%, making it particularly appropriate for differentiating and measuring even the smallest amount of oil in unconventional wells and those with changing salinities, high water cut, and high GVF.
