Update History (3 records)
Each row below records one filing or status update. Only the fields that changed from the prior record are shown; unchanged values are inherited from the row below. The oldest row (first known record) shows the initial state.
Note on permit dates: for TX this column reflects the completion permit on file (W-2 / G-1), not the original drilling permit (W-1). A re-completion later in the well’s life creates a new permit_date entry, which is why a permit can date after the spud.
