Guided Interpretation #5 • B05 - 24/32
B05.6.3 • MPT processing
In the present case, the objective of the MPT processing is to calculate at every depth an
average value of water holdup from the discrete measurements. This is performed by matching
the probe measurements with a 2D model representing the distribution of holdup. The
matching can include external constraints. With the knowledge of the holdups everywhere at
each depth, an integration is made over the entire cross-section to get the desired average.
In the PL Interpretation panel, click on the MPT processing button. The MPT processing window
opens in which the following choices are done:
Set the Tool type: Dual DEFT.
For the 2Dmodel select: MapFlo Holdups.
Use for Input: Independent passes Down2 and Up2.
Check ‘Average of the outputs’.
Leave the other choices as per default.
Press OK.
A message indicates that the processing will generate more than 200 points. This limitation is
meant to avoid heavy processing on slow computers, but you can change or remove it by
visiting the control panel Settings Interpretation option (‘Maximum number of output depths’ in
the Misc tab).
Press OK.
The results of the MPT processing (reconstructed data, errors and averages) are stored within
the interpretation where the process was launched. They can be accessed via the browser and
are displayed in automatic views.
In the browser, below the interpretation node, the ‘Calculated Log Data’ node gathers the
results of each pass included in the MPT process, as shown in Fig B0.30.
