Red Eye® Multiphase Water-Cut Meter

The Red Eye multiphase water-cut meter extends the unparalleled performance of Weatherford’s original Red Eye 2G water-cut meter to a full range of gas volume fractions (GVF). Designed to work in full three-phase flow (oil, water and gas), our multiphase meter measures relative water and oil concentrations in streams with up to 99.5% GVF.
At GVF levels above 99.5% this meter can be used for water onset detection. Using strong water absorption wavelengths in the near infrared (NIR), the multiphase meter can clearly detect water at or below 0.25 BBL/MMSCF.
The meter also has the ability to differentiate methanol or similar alcohol based hydrate inhibitors. By measuring five key wavelengths in the NIR spectrum, the Red Eye multiphase water-cut meter can distinguish four components (gas, water, methanol and condensate) in three phases (gas, liquid hydrocarbon and aqueous).
Applications
TheRed Eye multiphase water-cut meter is designed to work with vastly different types of flow like continuous liquid and gas flow streams and can be used for the following applications:
- Individual well production monitoring
- Water onset detection
- Undersized test separators
- Optimized injection of hydrate inhibitors
Features
The Red Eye multiphase water-cut meter uses a simple design that promotes longevity and accurate measurements for the life of the unit. The wetted end consists of a flange mounted or threaded insertion style probe. The probe has permanently sealed high-strength sapphire windows to isolate the process stream. The optoelectronics are mounted directly on the measurement probe, limiting field wiring to power and output signal cables. Key features include:
- Easy installation and configuration
- Non nuclear
- Compact and robust
- Low power
- Independent of typical phase density changes
- Salinity independent
- Slug frequency calculation
The meter is available for line sizes from 2 to 24 in. and pressure ratings up to ANSI 1500#. It is also available in a hot tap configuration for ANSI 600# applications.
