B02.4.2 13B• Spinner calibration and apparent velocity
 Select the ‘Survey’ panel.
The Up spinner passes need to be reverted, but the reversal is not for the entire pass. Note
that spinner reversal is for non-directional spinners only. The reversal could be defined
around the following depths: Up1=8640 ft , Up2=8580 ft , Up3=8560 ft.
The procedure for each pass is the same as applied for the shut-in:
 Make the pass active in the drop list of the top toolbar.
 Click on Spinner reversal.
 Click in the flowmeter plot around the indicated depth.
 Accept the defined depth and reversal direction (below).
 Reset the horizontal scale when done
Fig. B02.23 • Reversal defined
 Return to the ‘Interpretation’ panel.
 Click on ‘Calibrate’. The slopes and intercepts have been carried over from the shut-in, but
we will recompute them.
 In ‘Actions for all zones select to ‘Recompute all (no imposed threshold)’
 Make the top zone active, and click on the leftmost data point (blue) on the cross-plot with
the left mouse button.
A dialog appears indicating that this point is from Up3.
