SOR CORP Exempted Source Spool Piece Multiphase Flow Meter (SP MPFM)

The SOR CORP Exempted Source Spool Piece Multiphase Flow Meter (SP MPFM) represents a new generation of compact multiphase measurement technology designed specifically for oil and gas well monitoring and production testing. The system is engineered in a highly compact spool piece configuration, enabling installation in space constrained environments while maintaining high measurement performance across the full Gas Volume Fraction (GVF) range from 0 to 100 percent.

A key advantage of this system is the use of a very low activity Ba133 gamma source, which is classified as an exempted category by the International Atomic Energy Agency (IAEA). This classification eliminates the need for routine radioactive source licensing, handling, and regulatory management, significantly simplifying deployment and operation.

The SP MPFM integrates dual energy gamma measurement with venturi based flow technology to determine individual phase flow rates in three phase flow consisting of oil, gas, and water. The system analyzes gamma ray attenuation at two energy levels and applies a unity phase fraction assumption to compute real time phase fractions under actual production conditions.

By combining these phase fractions with total mass flow data from the venturi meter, along with inline pressure and temperature measurements, the system utilizes an embedded PVT model to calculate the flow rate of each phase under standard conditions with high reliability and accuracy.
