Formation data coverage

Formation summary: Stored source refresh: 2026-09-16. This formation/play summary uses recorded well and operator counts and permit dates in the preceding 24 months at summary refresh. Operator counts do not verify current operations. Summary counts and the separately refreshed permit and DUC lists may have different coverage. This is a capped directory of stored records, not a complete statewide count. Permit list: No stored records are available in this view; this does not establish zero activity. At most 50 displayed permit records match the formation name, ordered by permit date. This operator-linked list can differ from the summary permit count; a permit is not proof of drilling or production. This is a capped directory of stored records, not a complete statewide count. DUC list: No stored records are available in this view; this does not establish zero activity. At most 30 displayed records match the formation name, ordered by spud date. A spud date with no reported first production is a DUC proxy, not verified completion status. Elapsed days are computed at source refresh. This is a capped directory of stored records, not a complete statewide count.
