The activity log (tab ‘messages’) located at the bottom of the screen, displays the details of
the calculation during the Traverse tests. To see less detailed messages, go to Settings,
Interpretation, Activity log, select the Amethyste stone and set the verbosity level to a lower

Displaying one correlation at a time, by using the Correlation drop down list in the plot toolbar,
it is possible to visually identify the correlation that best matches the entered data for each
production test.
Let’s select ‘Petalas & Aziz’ as the reference. For this, minimize the plot and go back to the VLP
dialog, ‘Input: Wellbore’ tab.
Check the reference box
in front of the
Petalas & Aziz
correlation. This defines the correlation that will be used in the well performance analysis.
