Formation Tops

No tops on file for this well. Formation tops come from W-2/G-1 completion filings — this well has none yet, which is normal for permits that were never drilled, dry holes plugged without a filing, or wells completed before digital records. Offset-well tops can't be shown either — this well has no surface coordinates on file yet.
