Source: Oklahoma Corporation Commission 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 plays (SCOOP/STACK Woodford + Mississippian) carry materially different upside than single-bench mature plays.
Refresh cadence: Daily. Data current as of 2026-09-08.
