Historical source disclosure
Montana Well-Permit Archive
OilPriceAPI retains this source for historical and reference use, but does not publish its record counts, trends, or operator rankings as current permitting activity.
Current activity not supported
The Montana well-inventory collector maps its Completed field to permit_date, so the stored frontier is not a permit-issuance frontier (verified 2026-08-05)
Last successful source check: August 12, 2026. A successful check is not evidence that this archive represents newly issued permits.
