1.7.1.2 Creating Anchor Points
Link lines connect the points
where depth will be matched.
Only the section up to the
horizontal link line will be
shifted

Anchor points are represented through link lines. To draw a single link line, point at
a feature on the reference log. Click and simultaneously drag the mouse to the
corresponding feature on the log to be depth matched. Release the mouse button. A
link or correlation line will be created.
Single link line drawn between features to depth match. After commencing the depth matching process the line
would appear horizontal.
The above example shows a single link line between a gamma ray peak and a clay
rich layer. After depth matching the gamma ray peak will still be at the same depth
position but all logs selected for processing will be shifted up to match the new
depth given through the link line (the link line will be horizontal). Note that the
entire log section will be shifted up. If you want to exclude a section from being
depth matched limit it by horizontal link lines as shown below. Horizontal link lines
can be created by holding down the ALT key when dragging the line.
Everything above the horizontal link line will not be shifted.
Deleting link lines
To delete a link line simply press the CTRL key and click the line you want to
remove. To remove all of them select the Remove all links option from the Edit
menu.
