Validate multiphase meters. Quantify every phase.
Software for validating oil, gas, and water measurement from multiphase flow meters — with GUM uncertainty propagation, integrated thermodynamic modeling, and audit-ready validation reports for production and custody transfer.
Built for production allocation, well testing, and fiscal metering where oil, gas, and water must be measured and validated together.
What We Do
Multiphase meter validation software
IMS validates multiphase flow meters across oil, gas, and water — then calculates uncertainty for each phase. One platform for performance verification, drift detection, and defensible measurement budgets.
Connect multiphase data
Pull oil, gas, and water flow rates, water cut, GVF, pressure, and temperature from SCADA, historians, or field tests.
Oil · Gas · Water · WLR · GVF
Validate meter performance
Structured validation against references, drift baselines, and phase-split checks — per API MPMS multiphase guidance.
FAT · In-situ · Drift detection
Quantify phase uncertainty
GUM uncertainty and thermodynamic modeling for each phase, plus combined budgets auditors and allocation teams accept.
uc(y) · Expanded U · Per-phase budgets
What you get
Validated phases with uncertainty on every stream
Replaces manual multiphase test sheets and spreadsheet uncertainty models.
Live validation
Multiphase meters validated as conditions change
When GVF shifts, water cut drifts, or line pressure changes, IMS re-validates performance and recalculates phase uncertainty — so allocation and fiscal teams always have current, defensible numbers.
- Per-phase uncertainty — oil, gas, and water cut
- Validation against reference and baseline profiles
- Drift alerts when phase split degrades
- API MPMS and GUM-compliant validation reports
Computational Engine
Where Uncertainty Rigor Meets
Multiphase Thermodynamics
Spreadsheet multiphase validation breaks down at scale — and uncertainty numbers mean little if they ignore the underlying fluid physics. IMS combines rigorous GUM uncertainty propagation with deep multiphase thermodynamic modeling, integrating commercial thermodynamic simulators so metrologists, engineers, and OEMs are all speaking the same language.
GUM Propagation
Traceable uncertainty propagation for every measurement equation. Sensitivity coefficients, combined standard uncertainty, and expanded uncertainty with documented coverage factors.
- • Type A & Type B error sources
- • Sensitivity-ranked budgets
- • JCGM 100:2008 compliant
IMS Integrated Engine
Uncertainty propagation and thermodynamic behavior resolved together into one defensible budget — not a statistical estimate bolted onto a meter it doesn't understand.
- • Uncertainty budget tracking and propagation
- • Real-time fleet monitoring
- • Production-ready in weeks
Thermodynamic Modeling
We integrate commercial thermodynamic simulators to model PVT behavior and phase envelopes — so uncertainty reflects real fluid physics, not a black-box statistic.
- • Commercial simulator integration
- • PVT & phase-behavior modeling
- • Statistical uncertainty combined with OEM limitations
How It Works
From multiphase data to validated uncertainty
IMS automates multiphase meter validation — oil, gas, and water measured, validated, and uncertainty-quantified continuously across your fleet.
Ingest Multiphase Data
Connect oil, gas, and water flow rates, water cut, GVF, pressure, and temperature from SCADA or field tests.
Validate Phase Split
Check meter performance against references — drift on water cut, GVF, and per-phase flow rates.
GUM Propagation
GUM propagation informed by thermodynamic modeling for non-linear, multi-variable multiphase systems.
Per-Phase Uncertainty
Combined and expanded uncertainty budgets for oil, gas, water cut, and GVF.
Validation Report
Pass/fail status, drift alerts, and API MPMS multiphase validation exports.
GUM Combined Uncertainty
uc(y) = √Σ cᵢ² u²(xᵢ)
Expanded uncertainty U = k · uc(y) · k = 2 for ~95% coverage
Why Software
Beyond Spreadsheet Analysis
Manual GUM calculations break down at scale. IMS replaces error-prone spreadsheets with continuous, fleet-wide uncertainty management.
Standards Supported
Regulatory Compliance
Audit-ready documentation for custody transfer, EPA reporting, and ISO accreditation.
Metrology-Grade Math
Calculations traceable to JCGM 100:2008 with full sensitivity analysis.
Enterprise Security
Role-based access, SSO integration, and on-premise deployment options.
SCADA Integration
Native connectors for OPC-UA, Modbus, PI Historian, and REST APIs.
