General tab

This option hides the Welcome screen which allows you to open the previously accessed project, open an existing project, or create a new project. Instead, Petra will display the main screen in the closed project state.  To open a project or create a project, use the menus or speed buttons.

By default, Petra plots a small label in the lower left corner of all printed graphics showing the date and time the output was produced. Use this option to enable or disable the date-time label.

This option determines whether or not to apply top aliases when converting a zone interval to depths.

With this option selected, Petra will remember the location of the last file imported or exported, and use that pathway when the import or export dialog reopens.

With this option set, the main well and location tabs will not show US state-county and location buttons.

This option keeps dialog screens stay in the previous location on the screen after moving them. This is particularly useful with dual monitors.

The "SymTrans.DEF" file is used to translate well symbol codes during data import.  For example, a PI symbol code of 2GAS will be translated to simply GAS in the data base. Use this option to disable such translation.

When this option is deselected, Petra removes all records in all database tables associated with the deleted well.  Slow well deletions free up unused space, but can take a long time to complete.  The Fast Well Deletions option, on the other hand,  removes the reference to the deleted well (so it appears to be deleted), but does not actually remove the records in the database so the database continues to use the same amount of space on a hard drive.

This option highlights the well selected in the main module on the Map Module. This feature works best with dual monitor setup where you have the main on one screen and the map on another.

- Check this option if you are creating DXF files from a map or cross-section and the application that will read the DXF file cannot handle DXF "blocks" generated for well symbols.

This option disables the caching or buffering of database table updates. Importing data can be slowing with this option enabled.

Zone data item aliases are enabled when this option is checked. Zone item aliases perform like formation top aliases, allowing multiple sources of equivalent zone items to be searched based on a prioritized listed.

Check this option to suppress writing logging messages to the project's log file. Examples of logging messages are when wells are deleted or when the map projection changes.

This option can be used to control the default folder used when saving/loading various template files. Either the Private or Public Parms folder will be used.

Check this option to suppress the prompt you receive when changing between wells or tabs after changing data. Changes are saved automatically.

With this option checked, the main screen will display the data "tabs" with a button style instead of the normal tabs. With buttons, it is sometimes easier to see which tab you're on.

By default, PetraLog.TXT stores a comprehensive log file of changes made in the project.  This list includes map projection changes, well and seismic line deletions, and loading or saving overlays.  This option disables this log.

With this option enabled, the Main Module will show LatLon and XY values with more more decimal places on the Location tab.

This option forces Petra to use the total depth (TD) as a substitute for missing zone base values.  This can have a significant effect on calculations that use zone boundaries, including isopach and log calculations.  

By default, the Main and Map Modules open with the same set of wells selected when the module was closed.   With this option selected, the Map Module and Main Module will start up with all wells in the project selected.

During imports, Petra normally attempts to match 10, 12, and 14 digit API numbers from the input file with a 10, 12, or 14 digit well currently stored in the database. This will deactivate they checking and require imported wells to match the UWI exactly.

This is a display feature for the Main module's Tops and Zones tab.

This option allows Petra to import data while a prospect is selected, rather than the full set of wells in the project.

When importing data, the Windows "open dialog" screen is used. Petra modifies this dialog to add "favorite" buttons that allow you to quickly access the Desktop folder, the last used import folder, the Petra project folder, and the project's PARMS folder. You should disable (Check this item) this feature if your PC configuration causes a "place0 error"
