A new Depth log has been created containing all the shift marks created through
setting the anchor points.
The data can be compared against two depth axes now.
Two depth columns: The new reference (e.g. loggers depth) and the original reference for the shifted logs (e.g.
drillers depth) are shown in the log chart.
You will notice that only the document’s master depth axis is displayed linear – the
equidistant horizontal depth grid lines belong to the master depth axis. The created
Depth log might show stretched or squeezed sections.
Example of document’s master
depth axis and Depth log
showing the stretched and
squeezed sections caused by the
depth matching process.
