¾
Go to Survey – ‘Tool info’, ‘Multiple probe’ tab and select CAT-N tool.
¾
Ignore probes NCAP01, NCAP03, NCAP05 and NCAP06.
To obtain the holdups from the probe readings, the CAT needs to be calibrated on the basis of
pure gas/water/oil readings: for a normalized tool, these readings usually are: 0 in 100% gas,
1 in 100% water and ~ 0.2 in 100% oil.
¾
Click on ‘Calibration’, check ‘Use normalization’ and enter the values for oil as shown in
picture below and OK to close both windows.
‘Fit normalized...’ forces fitting the values within the 100% gas and water reading intervals.

what is happening in the well (and compare with what we have seen on the previous display).
