Weatherford has redefined the water-cut meter market by addressing many of the difficulties in accurately measuring water cut in flowing lines. The revolutionary Red Eye 2G water-cut meter was the first device to work with varying salinity levels, a wide-range of water-cut levels and entrained gas. It ignores changes in salinity, provides accurate measurements from 0 to 100 percent water-cut levels and can handle up to 20 percent gas-volume fractions (GVF).

The Red Eye MP water-cut meter extends this unparalleled performance to a full range of GVF. Designed to work in full three-phase flow (oil, water and gas), the multiphase meter measures relative water and oil concentrations in streams with up to 99.5 percent GVF.

At GVF levels above 99.5 percent 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 MP water-cut meter can distinguish four components (gas, water, methanol and condensate) in three phases (gas, liquid hydrocarbon and aqueous).

Red Eye MP Water-Cut Meter Features

The Red Eye MP 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:

The meter offers both real-time water-cut measurement plus a liquid weighted average over a user-specified time period. This is especially useful when slug flow is occurring. 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.

Red Eye MP Water-Cut Meter Applications

The Red Eye MP water-cut meter is designed to work with vastly different types of flow. It works in continuous liquid and gas flow streams. These new design elements have been incorporated with the existing capabilities developed for our earlier water-cut meter, creating a tool that performs beyond the industry standards in a wide breadth of situations.
