Export ASCII tops file

File tab

The file tab contains the file name and export format options.

·Output File - Use the "Browse" button to select or enter the name of the text file for writing formation tops.

·Select Tops - Opens the Select Zone Item List.  Note that this list only includes tops in the FMTOPS zone.  To add tops to the file, select the relevant top on the Zone Item list.  

·Use Aliases - Uses formation top aliases.  If a well's value for a top is NULL, Petra will use the alias list to find a substitute "equivalent" top.

·Output Tops if "Null" - Normally, NULL valued tops are not written to the export file. This option writes the user-created null value to the top instead.

·"Null" Value Indicator - Sets the value that will be written to missing NULL tops.

·Format - Sets whether the exported file will have fixed columns or will be separated by columns.
