Resistivity Array Tool (RAT)
The cross-sectional water holdup profile is determined through a series of 12 micro resistance sensors mounted on bowsprings at 30° intervals, ensuring 360° borehole coverage. Oil, gas and water have different conductivities; water (brine) is conductive, while oil and gas are non-conductive. The RAT incorporates a relative bearing measurement to indicate the high side of the well.
APPLICATIONS
- Water Holdup in vertical, deviated, highly deviated & horizontal wells
- Cross-sectional water holdup profiling
- Phase segregation mapping along the wellbore
- Identification of water entry/production loss areas
- Changes in wellbore fluids with time/different production rates

Capacitance Array Tool (CAT)
The CAT tool is designed to solve the problem of accurate fluid phase identification in vertical, horizontal or highly deviated wells. The tool has an array of 12 specially developed miniature capacitance sensors mounted on the inside of a set of bow-springs. Each sensor of the array measures the capacitance of the surrounding fluid close to the well casing. Since the measurements are taken in a single plane across the diameter of the wellbore, rather than spaced along it, an accurate cross-sectional plot can be generated.
APPLICATIONS
- Phase identification in horizontal & highly deviated wells
- Calculation of phase percentage present
- Plotting of phase composition along the wellbore
- Identification of water entry/production loss areas
- Changes in wellbore fluids with time/different production rates

Spinner Array Tool (SAT)
Discreet local fluid velocities are obtained through a series of six (6) miniature flowmeters / spinners deployed on bowspring arms at 60° intervals ensuring 360° wellbore coverage. Traditional correlations have used the total fluid velocity and then estimated the individual phase velocities; lighter phases migrate to the high side of the well, the heavier phases to the low side. The SAT allows direct measurment of the individual fluid phase flow at their own unique velocities and directions incorporated with a relative bearing measurement to indicate high side of the well.
APPLICATIONS
- Phase velocity segregation in deviated, highly deviated & horizontal wells
- Direct measurement of individual phase velocities present
- Plotting of phase velocities across the wellbore
- Identification of water entry/production loss areas
- Changes in wellbore fluids with time/different production rates
