1. Multiphase Metering
Principle of Operation
Multiphase Meters are used to determine in real time the volumes of oil, gas and water produced by an oil well, a group of wells (current flow), collection stations in production fields or offshore platforms, without any previous separation.
The scope of applications for the multiphase meter is:
- Exploration and production testing of wells.
- Monitoring of production at real time.
- Delivery or distribution measurement.
The solution consists of a Venturi tube, a Pressure Sensor, a temperature sensor, a Gravitational Densitometer and a Water Cut Meter.
2. Water Cut Meter
Principle of Operation
The Water Cut Meter measures the volume fraction of water in a liquid mixture using “microwave absorption technology”.
This technology takes advantage of the distinct difference in the microwave energy absorption between the oil and water.
A microwave signal with a precise frequency is send through the liquid mixture, the intensity of the transmitted signal decreases exponentially with increasing volume fraction of water in the liquid mixture based on the Beer-Lambert law.
A Data Analysis System (DAS) is used to acquire, amplify and process the transmitted microwave signal and sends a signal of 4-20 mA and a digital signal RS485 corresponding to the water cut in the liquid mixture.
