What is Multiphase meter? The Multiphase meter Technology is the combination of the robust concept of Venturi and well known and unique measurement of Multi-Energy Gamma Ray to replace conventional well testing Arvand Azin Aryan

Measures fraction and velocity of oil fraction and velocity of water fraction and velocity of gas Outputs Oil rate Water rate Gas rate Arvand Azin Aryan

Gamma-rays detector Ba133 source Venturi Flow ΔPΔP Venturi  Total mass flow rate (Bernoulli) Source and detector  3 phases fractions (nuclear attenuatio) PVT model  Convert from line to standard conditions Output -> Oil, Gas, Water flowrates at standard conditions Arvand Azin Aryan

Q total mass = q total vol. *  mixture = v * A *  Mass Flow rate = (Volumetric Flow rate) (Mixture Density) = (Mixture Velocity ) (Venturi Throat Area) (Mixture) Density Arvand Azin Aryan

Venturi & Delta P Source & Detector Single- phase rates Multiphase* Technology – Calculations overview Arvand Azin Aryan

Technology Overview and advantages No phase separation, No moving parts No tuning factor, No flow calibration WLR is not phase distribution dependent Different sizes: 29, 52, 65, 88 (150 – 150,000 bpd) No Sensor in direct contact with the fluid Actual measurement at production conditions Low Differential Pressure Design No stabilization required Compact Solution Arvand Azin Aryan Sep. 2015

Features and Benefits Operation efficiency and safety  Compact, lightweight & small footprint  Limited pressure test lines  Simple equipment mobilization  Reduced crew  Short operation duration, saving rig time and reducing flaring  fast rig-up and rig down  clean-up optimization  no stabilization time required  On line, continuous production monitoring  No moving part (low failure probability) Data quality & Metrological performance  Improved accuracy vs. conventional testing  High repeatability  Independent of flow regimes  Exceptional dynamic response  Flow rate measurements during all clean- up  Early water detection  Not affected by slugs, foam and emulsion  Unique hardware for heavy oil, black oil, volatile oil, gas condensate, wet gas and dry gas well testing Reduce the Operation cost Arvand Azin Aryan
