Buckhead Energy computes every figure on this page from grouped records in public oil and gas data. The page shows counts, sums, percentiles and indexes only; it does not list individual wells, leases or permits.
Counts under 3 wells and percentiles under 5 wells are withheld; totals are floors.
Share is the formation’s permits as a percent of the state’s permits that year. Median lateral length is published only when at least 5 permits stand behind it.
Last computed: 2026-11-06. These figures are informational only and are not a valuation of any mineral or royalty interest.
