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

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

Features and BenefitsOperation 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

Results
We can subtract H8 oil Q=1761.9-1580=181.9 STB/d, gas Q=163.54-142.03=21.51 MScf/d, water Q=590.86-382.01=208.85 STB/d.
BSW=590.86/(590.86+163.54)=78%
