Guided Interpretation #9 • B09 - 13/22
In independent mode, the readings of the selected passes are matched pass by pass at every
depth, fitting a new 2D model on each pass. In combined mode, the readings of the selected
passes are all matched simultaneously at each depth, using the same 2D model: this mode
behaves as if there was, for instance, a SAT tool with twice the number of probes when processing
a SAT in two passes in combined mode. This can be of great interest when some probes failed in
one pass but not in another. Bear in mind that this mode is valid only if the flow conditions have
not changed or are very similar between the passes.

Choose to generate ‘Error channels’, ‘Average of the outputs’ and ‘Phase rates’.
‘Error channels’ are the relative errors between the raw and the reconstructed data. ‘Average of
the outputs’ generates the MPT process averages for the interpretation input (e.g. the combined
process average or the lateral average of the selected passes in independent mode). ‘Phase rates’
will produce the reconstructed rates of the phases.

When OK is given Emeraude indicates that the process will generate more points than a maximum
defined in ‘Settings – Interpretation – Misc’. The interval will be changed automatically to honor
this condition. Accept with OK.
At the end of the process a number of new channels have been created under the ‘Calculated Log
Data’ folder in the browser. The next figure gives the details.
