Multi-Phase Flow Meter (MPFM) Analysis

Challenge

Multi-phase flow meters are important for well surveillance and production allocation where there is multiple ownership. It is therefore important to track the accuracy of multi-phase flow meters, identify issues and ensure rapid corrective action.

Solution

The Seeq tools were used to analyze and monitor performance:

  • Totalize multi-phase flow meter data dynamically
  • Reconcile the total meter measurements with sales measurements
  • Build analytics to identify root causes when there is a significant discrepancy

Benefits

The benefits of the analytics are:

  • Faster detection of metering errors that would impact well surveillance and material accounting
  • Higher productivity for engineers and maintenance by more rapidly identifying causes of measurement discrepancies in near-real time

Data Sources

  • Ignition SCADA

Data Cleansing

  • Formulas used to correct flows for expansion due to pressure and temperature

Calculations and Capsules

  • Formula summed all multi-phase flow meter measurements
  • Value Search created capsules for large discrepancies between sum of multi-phase flows and main separator flow

Summarizing Results

  • Workbench Worksheets and Organizer topics are used to present analysis results
