Editing correlations

You are here:

You access most correlation editing functionality by right-clicking a correlation on the depth page.

Right-click the correlation to modify and select from the following:

Edit correlation, to display the Edit Correlations/Nodes dialog box and specify the name and display style of the correlation and depth of nodes along it.
Delete to remove the entire correlation. To restore a deleted correlation recently after deleting it, select Edit > Undo > Delete a correlation.
Break to display the Break Old Correlation, Rename New Correlations dialog box and type names by which to identify the segments left and right of the break. The break occurs where you right-clicked the segment. Segments keep the names you type here even after they're attached to a different segment or reconnected.
If the correlation you break defines a zone, the zone is deleted.
Extend to change your cursor to a cross-hair () with which you click to define nodes. If neither end of the correlation are latched to a well or to the models vertical scale, a dialog prompts you whether to extend the left or right node.
You can continue to create nodes until your cursor crosses either an existing correlation or the vertical scale of the depth model. In both cases the correlation will latch and if possible, create a zone.
You can reconnect broken nodes by either selecting Extend or by simply dragging the node nearest the break over an existing correlation so it latches.
Add a node, to place a node on the location you right-clicked. Adding nodes enables you to increase precision when defining geological anomalies.
