WellCAD Basics - Advanced Logic Technology

To use an alias table during import of data
BOOK 1 - WELLCAD BASICS - 79
Log titles in WellCAD are unique identifiers of the data container (i.e. the log). They
allow templates to copy settings to the correct log or formulas to find the right data
source for computations. Also the automated upload of data to databases often
depends on consistent use of the log title.
When data files are imported the title of the new WellCAD log depends on the
mnemonics (channel names) of the imported file. This often leads to a mismatch of
imported and expected titles – expected titles would be the standardized names. As a
consequence the user would be required to check and eventually rename the log
titles each time a new data file was imported.
Since WellCAD v4.3 so called Alias Tables can be created by the user. Alias
Tables contain standard Names and for each of these standardized names a list of
possible Aliases can be defined. Whenever, during import of a data file, the
imported data channel name corresponds to one of the Aliases it will be renamed to
the standard name and set as the new log title.
The following screen shot shows a sample of an Alias Table:
Whenever a data channel with the mnemonic GR, GRDE or GAMMA] is imported
the resulting log title in WellCAD for this data will be set to Gamma Ray. A data
channel CADE will result in a log title Caliper.
A new entry mentioning the original mnemonic will be added to the log history,
whenever renaming occurs.
Enabling the use of an Alias Table:
The use of Alias Tables is optional. To enable the use of Alias Tables:
� Open the Tools > Options… dialog box.
� In the tree control click the Alias Table entry.
