The Weatherford Red Eye subsea water-cut meter uses near-infrared light to provide water-onset detection, water-cut measurement, and water-to-hydrate interior ratio measurement. The meter operates in a full three-phase flow stream at any gas volume fraction, and is unaffected by changes in salinity, hydrogen sulfide, or carbon dioxide, thus eliminating the need for corrections related to those factors. It is capable of measuring water cut in a multiphase line and enabling the measurement of relative concentrations of water and hydrate inhibitor. A subsea flow measurement system typically measures the commingled production from multiple wells. The meter enables operators to track the water production of each individual well. It also offers the ability to track hydrate inhibitor concentrations to ensure that conditions are outside of the hydrate formation range.
