Source: West Virginia Department of Environmental Protection, Office of Oil and Gas (WVDEP OOG) well-header records, aggregated by primary play / interpreted formation / basin.
Threshold: Only formations with at least 50 wells are listed (excludes one-off wildcat plays).
Why it matters: Knowing which formation underlies your tract — and which operators are actively drilling that formation — is the foundation of mineral-rights valuation. Stacked-pay plays carry materially different upside than mature single-bench plays.
Refresh cadence: Monthly. Data current as of 2026-08-12.
