Next-Generation Non-Radioactive Multiphase Flow Metering
Combining Low-Field Nuclear Magnetic Resonance (NMR) and Compressed Sensing to deliver unparalleled accuracy without radioactive isotopes or pipeline separation.
Why Now
The multiphase metering market is under structural pressure to move away from radioactive sources, just as Brazil's pre-salt enters its largest investment cycle in history.
Global MPFM Market
A multiphase flow metering market growing ~7%/year, today concentrated in five incumbents that control roughly 60% of share.
Petrobras E&P CAPEX 2026–30
With 14 new FPSOs planned through 2027 and most spend directed at pre-salt, every new field needs per-well allocation metering.
Hidden Cost of Nuclear Sources
Civil-liability insurance premiums for radioactive gamma meters can reach tens of thousands of dollars per unit each month — a direct driver for non-nuclear technology.
Cost Cited as Adoption Barrier
Four in ten operators cite the prohibitive cost of current MPFMs as the main obstacle to wider adoption — an opening for a leaner, safer architecture.
The Paradigm Shift
Compare the features of traditional multiphase meters against EchoFlow's safe, compact, and high-precision magnetic resonance spool.
State-of-the-Art Metrology
By merging low-field Nuclear Magnetic Resonance with advanced signal reconstruction, we solve the oil industry's hardest metrological challenge.
Low-Field NMR
Excites hydrogen nuclei in the flowing oil, water, and gas phases to measure phase velocities and hold-ups directly inside the spool — no probes, no radioactive sources, no separation.
Compressed Sensing
Compressed sensing accelerates acquisition by 4x to 8x versus conventional sampling, letting the system capture rapid flow transitions and transient gas slugs that legacy meters smear or miss.
Real-Time Reconstruction
Iterative reconstruction turns sparse measurements into real-time phase-flow profiles. In high-fidelity simulation, the method reaches a U95 gas uncertainty of 1.2% — the accuracy class targeted by API MPMS 20.3.
Dynamic Flow Regime Classification
Different flow regimes (stratified, annular, bubbly, or slug) alter signal attenuation. EchoFlow incorporates an intelligent classifier trained on the 3W Multiphase Flow dataset, dynamically identifying regimes to correct velocity and water-cut calculations in real-time.
Development stage: performance figures reflect high-fidelity simulation. Hardware validation is in progress (TRL 4). Metrology consulting services are available today.
Where It Delivers
Built for the hardest measurement environments in offshore oil & gas — from ultra-deepwater pre-salt to high water-cut mature fields.
Pre-Salt Allocation
Deepwater, high-CO₂, high-pressure pre-salt fields demand precise per-well allocation. A non-radioactive, compact spool fits where heavy nuclear meters cannot.
Mature High-Water-Cut Fields
In fields with water cut above 85%, accurate phase metering is critical for revitalization and water-injection optimization — a regime where microwave and gamma meters struggle.
Shared FPSO Allocation
FPSOs gathering multiple wells require per-well allocation for fiscal split and reservoir control. Compact spools enable metering on space- and weight-constrained decks.
Subsea Tie-Backs & Satellites
Long tie-backs and satellite fields need continuous flow monitoring to safeguard flow assurance and production accounting across the gathering network.
