WellCAD Basics - Advanced Logic Technology

Select the depth reference that
corresponds to the incoming
data.
Data must be re-sampled if the
selected depth reference in the
Borehole Document is not
linear.
1.7.3 Using Time Based Data
BOOK 1 - WELLCAD BASICS - 195
Text File Import Wizard allows to select the correct depth reference if the information is available as Depth log
within the Borehole Document.
Besides managing different depth references in a single Borehole Document using
Depth logs it is possible to have a time axis as well. The date/time values can be
handled in the document’s master axis as well as in a separate Depth log. Switching
between depth and time reference is possible as long as the axis contains no
reversals – just right click on the log title and select the Use as depth scale option.
You could think about a Borehole Document reporting a drilling process. This log
chart would have a date/time axis next to a MD and TVD depth axis.
