Enter depth span to
entire data set shift up
or down
1.3.2.8 Merging Equal Items
Enter the depth span by which you want to shift the data set. As depth is counted
positive when going downwards, you will have to enter a positive value to shift your
data set down, a negative number to shift the data upwards.
A copy of the original log (data set) will be generated and added to the borehole
document containing the shifted data.
A constant depth shift has been
applied and a shifted copy of the
original log has been inserted
Note:
This process applies a constant shift only. In order to depth match a data set against
a given reference – and apply non-linear shifts – you have to use the Depth
Matcher tool (1.7.1 Depth Matching).
If log types dealing with interval data – Litho, Comment, CoreDesc and Interval
Logs – are used, data values of adjacent intervals might be equal. To merge all
intervals with equal data together, choose the Merge Log Items command from
the Edit menu.
