By decade, production averaged most in the 1980s (75 Mbbl/d); the 2020s so far average 62. The highest month in that year was September 2006 at 102 Mbbl/d. Its share of U.S. output peaked at 1.9% in 2006.

Monthly output swung between 69 (June 2026) and 85 (October 2025) over the past 12 months; the latest figure is 69 Mbbl/d for July 2026. Ohio ranks just above with 137 Mbbl/d (it moved ahead of Montana in 2022) and Louisiana just below with 74 (Montana moved ahead in 2025). EIA estimated Montana's proved crude oil reserves at 316 million barrels at the end of 2021, 11th among states; reserves are a separate measure from production.
