Guided Interpretation #9 • B09 - 6/22
Fig. B09.6 • Image view cross-section
On the right, the position of the probes is indicated for passes D2 and D3. On the left, markers
indicate probe raw measurements at their relative position projected on the vertical axis, and
honoring the pass colors (green for pass D2, blue for pass D3: for ease of probe identification,
a popup window displaying the probe number concatenated with the pass short name is
displayed when the mouse cursor points at one of the probe marker). The red line corresponds
to the model chosen, linear in this case. Note that, if a probe is not active, the corresponding
marker will not be shown on the left plot.
B09.2.2 • RAT Data Display
To differentiate between water and hydrocarbons, the RAT needs to be calibrated and typical
values are 0.5 for 100% water and 1 for 100% hydrocarbons.
¾
Go to Survey – ‘Tool info’, ‘Multiple probe’ tab and select RAT-Mean tool.
¾
Click on ‘Calibration’, check ‘Use normalization’ and ensure that ‘Fit normalized values to
defined interval’ is checked.
¾
Click OK twice to close both windows.
‘Fit normalized...’ forces fitting the values within the 100% hydrocarbon and 100% water
reading interval for each probe.
¾
From the display toolbar, call the template button
.
¾
Among the Sondex Templates, Full Layouts select ’RAT MEAN Probes’.
To compare the probe readings, the scale of all tracks should be the same. This can be set at
once.
¾
Right click on any track and select ‘Horizontal Scale…’.
¾
Enter the information as shown in the next window (do not forget to tick ‘Apply to all
water holdup data from the same MPT’) and click OK.
