This page is computed from public records: well-level records for Colorado in the US Department of the Interior Orphaned Wells Program Office data layer (filter the county column for Adams).

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.
