Every figure on this page is computed from public records you can inspect:

Well-level records for Oklahoma in the US Department of the Interior Orphaned Wells Program Office data layer (well identifier, county, type, reported cost, date).
Orphaned Wells Program maps and data, US Department of the Interior.

Costs are as reported by the grant recipient. See limitations.

Data through 2026-06-30. Sample sizes are the wells behind each figure. Grades come from held-out tests, not in-sample fit: A needs 200+ independent cost observations and a held-out error of 25% or less; B needs 60+ and 40% or less. Anything weaker is shown as Insufficient data. How grading works.

Some figures here are withheld because the data is too thin to grade. If you hold actual plugging costs, report a plugging cost. Reports are reviewed before any use.
