The improved design, in addition to providing greater discrimination in higher water cuts, also minimizes the “watering out” effect. This effect results in tool output continuing to indicate water even though the surrounding fluid has been replaced by hydrocarbons.
The tool is essentially an annular capacitor with the central probe and external cage acting as the capacitor plates and the well fluid flowing between the plates as the dielectric. The difference in the dielectrics of water & oil are detected by the tool and output as a frequency change. Water hold-up is determined by reference to a hold-up / fractional response chart.
