What we cover here

Each row names the grain a region’s production is held at. Where a source publishes at a coarser grain, the page says so.

DataGrainSinceBenchmark
Montana production well 1986-01 ~96–100% of EIA

Benchmark cells compare our series with the EIA’s published estimates.

About the EIA comparison

The two are produced differently: the EIA estimates from a survey of the largest operators and a model built to anticipate late filings, while the series compared here are rebuilt from the source’s own records as they arrive. Recent months can differ without either being wrong; the methodology page explains both methods.

Coverage rows for Blaine County, Montana are regenerated at every build from the same catalog of sources the data is built from.

What the data shows

  • Blaine County, Montana produced 250 Mbbl (thousand barrels) of oil and 2.2 Bcf of natural gas in 2025.
