WellCAD Basics - Advanced Logic Technology

Shift by:
Performs a constant depth shift of the entire data set.
Conversion to other log types:
APPENDIX A - 253
The Mud Log can be converted to Well Log, Comment Log, Stacking Pattern Log
and Depth Column Log. Select the log to convert and use one of the conversion
option from the Edit > Convert Log To menu.
Mud Log to Well Log:
The Mud Log can be converted to a Well Log. The following dialog box will open:
The Well Log requires a
constant sampling rate.
Choose whether an interpolation between data
points is performed or not.
As the Well Log data type requires a constant sampling rate you have to set a value
for the depth-sampling interval. In addition you can choose whether an interpolation
between data points is performed during re-sampling the data or not.
If Do not interpolate is selected data points from the Mud Log will be taken when
their depth matches the new depth of the Well Log determined by the sample rate.
The Tolerance parameter allows finding the nearest value in the Mud Log within
the range depth +/- Tolerance. If the closest Mud Log value is outside the tolerance
limits a NULL value will be set.
Use previous data repeats the last data while Interpolate performs a linear
interpolation between the nearest Mud Log data points.
