Cutting logs

You are here:

Cutting logs

Cut a section from a log and then either lower the start depth or raise the stop depth so that either the tops below or above the cut maintain accurate depths.

If you change the shallowest or deepest depth in the entire depth page, also resize the model by either dragging the canvas borders or by changing the display range in the Display Parameters: Depth Model tab so that portions of the depth model that aren't occupied by any wells, but that would otherwise influence your time model, are removed.

You can also insert a constant value log section the same thickness as the section removed. For details, seeRelated Topics below.

To cut logs:

Open the log editor:

Edit > Log editing
Double click on a log in the model.
Right-click on a log and select Log editing.

Click the Cut tool () on the Log Editortoolbar.

The Cut dialog box opens.

Do one of the following:

Drag the cursor () on the Log Editor log display pane to select a range to cut.
Type more precise values in the Depth range pane for the start and stop depth and click Update.
Click either top or bottom to accept the absolute depth from the log.
Click Depths from tops to display the Depth Range from Tops dialog box and then select the formation tops that signify your zone of interest from the drop-down lists and click OK.

Click Apply.
