Merging logs
Merge an upper run with a lower run using the Merge Log Runs tool (
) on the Log Editor by importing
a log in either LAS or GeoSyn format. You can also use the Math tool or the Composite Log tool to merge runs; however, the Merge Log Runs tool is the simplest and quickest method.
To merge 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.
- Using the Log Editor toolbar, click
the Merge Log Runs tool ().
The Import Log Data dialog box opens.
- Select the log file to merge with the existing log, and then click Import. A warning dialog may appear warning of a mismatching kelly bushing depth between the two logs. Continue to import the log file and change the kelly bushing depth of the imported well using the Merge Log Runs dialog box that appears below.
The Merge Log Runs dialog box opens.
- Using the Host and Donor panes that appear in the bottom-left of the Merge Log Runs dialog box, select the log to merge with and the imported log to merge in either pane.
The display in the Unmerged Logs display pane updates to reflect the relationship of the two selected logs.
To set the area of interest, to the left of the Show label at the bottom of the Merge Log Runs dialog box, specify whether to show the entire depth of both log runs in the Unmerged Logs display pane, or just the depth where they overlap.
To clarify the display, enable or disable the Scales check box to specify whether horizontal and vertical scale lines appear in the Unmerged Logs display pane. Click the Zoom buttons to the right of the Unmerged logs display pane to change the zoom resolution.
To set the specific point at which to merge the logs, either drag the slider to the left of the Unmerged Logs pane (or drag the display pane), or type a specific depth in the box to the right of the Merge at button below the Unmerged Logs display pane and then click Update.
Specify whether to include tops from either (or both) the host or donor well.
- Click Merge at to perform the actual log splice.
The spliced log appears in the Merged Logs pane in the right portion of the Merge Log Runs dialog box with merge details in the table below the Merged Logs display pane.
- Either complete the above steps for additional logs to merge in the GeoSyn well,
OR
Click OK to return to the Log Editor.
