The Depth section provides the option to limit the depth interval from which the
data will be exported. Additionally, if a Depth Column Log that can be used as
Depth Scale (see 1.7.2 Handling Different Depth Systems) is contained in the
Borehole Document, one can select this Depth Column Log from the System drop
down list to export the data using a different depth system. If the master depth axis
corresponds to Measured Depth (MD) and a Depth Column Log with True Vertical
Depth (TVD) information exists the user would have the choice to export the
selected data channels with reference to MD or TVD.
Two Export Modes are available. The user can export all data channels using the
same constant sampling rate or the values can be read and exported from distinct
depth locations, which are provided by a reference log. E.g. core permeability values
have been determined from plug samples. The values are stored in a Mud Log with
the depth values corresponding to the plug positions. Gamma Ray and Density
values are available from a wireline logging run. To create a file with Gamma Ray
and Density values at the plug positions the Permeability log can be used as
reference log providing the corresponding depth values. All logs handling point data
(Well- , Mud-, Percentage-, Analysis- and Depth Logs) can be used.
To summarize the different ASCII data export options we look at a Lithology Log.
Selecting the log and using the File > Export> Single File option will allow the
user to generate a TXT or WAL file of the following format:
Top Depth, Bottom Depth, Pattern Code, Hardness, Top
contact, Bottom contact
If the Lithology Log has not been selected and the File > Export> Single File
option is used the user can export a TXT file using a constant depth sampling rate.
The lithology would be exported in the following format:
Depth, Pattern Code
If a reference log is used to provide the depth positions the exported data will be of
the format Depth, Pattern Code as well.
Before printing you should ensure that an appropriate Windows Printer Driver is
installed on your computer and that the correct driver has been set up for your
printer.
Printer Setup options depend upon your operating system. In any case you should
be able to select your printer from a list and set printer specific properties. If you
