The Log Maintenance Tool creates, deletes, and renames log definitions. This tool can also change the default log scales and lock/unlock a curve for the entire database.
The Log Maintenance Tool
Delete... - This option deletes the log definition and all associated data for all wells in the database.
Rename... - This option changes the name and descriptive text for a log definition.
Scale... - This option sets the default scale for the log.
New... - This option creates a new log definition. Note that the new definition will have no log data (0 wells) associated with the new log definition.

Wells... - This option displays the "Select Wells" screen with the wells containing the highlighted log.
Lock/Unlock - This option globally locks or unlocks the selected log definition.
