Source: Ohio Department of Natural Resources well-header records aggregated by county.
Threshold: Counties with at least 10 wells on file are ranked (excludes counties with no oil-and-gas activity).
Why it matters: County-level drilling activity is the geographic foundation of mineral-rights valuation in Ohio. The hottest counties (Canadian, Kingfisher, Grady, Stephens) command premium pricing in the Utica/Point Pleasant; quieter eastern counties may still hold legacy production with steady royalty income.
Refresh cadence: Monthly. Data current as of 2026-07-27.
Whether you're in a top-tier Utica/Point Pleasant county or a steady-producing legacy county, get a free written offer based on your specific tract.
