When working in AccuX DB mode, you can use AccuMap system tops (those provided by data vendors), AccuMap user tops (system tops you've modified), or generic tops (tops specific to the current project or that you created in AccuX without associating an AccuMap mnemonic). Changes you make to AccuMap user tops are written back to the AccuMap database of user tops. Generic tops are only saved with the AccuX project (depending on whether you're working in DB mode or Project mode).
Tops in DB mode are denoted by a letter beside the name of the top in the cross section display so you know whether it's a System <S>, User <U>, or Generic <G> top. Any system top you move automatically becomes a user top.
When working in Project mode, all tops are generic tops because they pertain to only the current project. Changes you make to them aren't written to the AccuMap user tops database.
You can pick formation tops in wells, change their depths, and change their individual display properties.
When working in DB mode, tops for which you change the depth or that you place in a well are automatically saved to the AccuMap user tops database, but individual display properties aren't saved.
You can create your own tops to place between existing tops and using the Mineral Accessories and Lithology Pattern toolbars, fill areas between tops to replicate subsurface mineralogy and lithology.
When working in the Map Viewer in DB mode, you can export generic tops to Microsoft Excel. The export includes the Well UWI, followed by each generic top, and the KB elevation. You can then modify these tops and work with them in other applications. To import them into your AccuMap user tops database, you must associate them with an existing formation top during the import process.
You can import tops into AccuX from .xls, .csv, or .txt files. After importing tops, you must close and then launch the cross section again before they're visible in wells.
