Top Import Spreadsheet Format:

If the "Create new formations in strat columns for missing formation names" option is active during import and there is no matching formationname for a formation in the referenced well's strat column then new formations will be created using the formation data from this sheet. To be valid, a row must contain a value for either the mdtvd or elevation columns

The column headers will specify which columns are Required, Recommended, and Suggested.

  • uwi (text): Unique Well Identifier (UWI) of the Well that the Tops data is related to. This can be the API or any text

  • formationname (text): The name of the Formation the pick represents. This should match the related formation in the associated Strat Column, case-sensitive

  • formationsymbol (text): The symbol of the Formation the pick represents, no character limit
