Figures are Buckhead Energy analysis of public oil and gas data. A county's oil total counts only months in which at least 3 wells reported oil, and its gas total only months in which at least 3 wells reported gas, so totals are floors; "<3" marks a total withheld under that rule. Figures are for research and reference; they are not a valuation. Spotted an error? Tell us and we'll note it.
