Copy’n Paste
When copying and pasting data between documents with different master depth axes the user has to choose the
right depth reference.
The depth values of the core porosity log from the example above will be converted
to Logger’s depth using the depth correspondence data stored in the Core Depth
log.
Impacts on data import and export
When selecting a single log and exporting it as a *.TXT or *.WA* file, the depth
values written into the file will correspond to the currently selected depth scale of
the Borehole Document. The same happens if multiple *.WA* files are exported. If
none or multiple logs have been selected and are exported as *.TXT file the dialog
that opens allows setting the depth reference explicitly. A other file formats use the
Borehole Document’s master depth by default.
When importing ASCII data using the Text File Import Wizard (see 1.4.2.2 TXT,
CSV and ASCII Import) the last step allows setting the depth reference of the
incoming data. E.g. if core analysis data recorded in Driller’s Depth is imported and
the Borehole Document contains a Logger’s Depth master axis and a Driller’s
Depth log you can select from a drop down list the correct depth reference. Please
note that it might be necessary to resample the incoming data in order to maintain a
constant sampling rate.
