Multiphase flow metering in deepwater production: the error budget nobody audits

Gas void fraction uncertainty cascades through every layer of a MPFM stack. How a 4% GVF measurement error in the test separator model became a 12% production allocation discrepancy at year-end.

• Measurement uncertainty budget and error propagation methodology
• Field readings compared against calibrated reference instruments
• Statistical analysis across multiple wells and flow conditions
• Practical corrections and guidance for allocation reporting
