Red Eye® 2G Water-Cut Meter
The Red Eye 2G water-cut meter uses patented optical sensor technology to accurately measure the full range of water cut (0 to 100 percent) in a commingled oil and water stream. Very high accuracy across all water-cut levels and easy installation and configuration make this unique meter suitable for numerous applications. The meter can be used in standalone mode to measure and report instantaneous water cut and with the Red Eye net oil computer (NOC) to perform timed production well tests, or as part of the Red Eye metering system (REMMS).
How Does the Red Eye 2G Water-Cut Meter Work?
The measurement is based on near-infrared absorption spectroscopy where oil and water are easily differentiated.
The water-cut meter achieves unmatched accuracy at high water-cut levels as well as lower water-cut measurements by simultaneously measuring multiple wavelengths that include water and oil absorption peaks.
Red Eye 2G Water-Cut Meter Highlights
- Unmatched accuracy in real-world situations
- Insensitive to entrained gas
- Ignores salinity and dissolved gas
- Easy installation, calibration and service
Red Eye 2G Water-Cut Meter Typical Applications
- Well testing - The water-cut meter is typically used downstream from a two-phase test separator in the liquid leg. The meter can be combined with a total liquid flowmeter and NOC for individual oil and water flow rates.
- Individual well monitoring - The Red Eye 2G water-cut meter can be used to monitor individual wells and provide continuous real-time, water-cut data. When streams contain free gas (up to 20 percent GVF), the meter provides unsurpassed performance in accurate determination of oil and water rates.
- Group production at centralized facilities - The water-cut meter can be used to monitor group production lines as well as individual test lines. The compact insertion-style design is very cost effective even for large line sizes.
- Dewatering monitoring systems for crude oil tanks - When a Red Eye 2G water-cut meter is installed on the discharge line from a tank, the operator can easily identify the rag layer (interface between the oil and water in the tank). The optical sensors of the meter sense very small amounts of oil in the rag layer as it passes through the pipe, enabling the operator to shut off the flow from the tank.
