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

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.
