Oil and gas are the Railroad Commission's county figures from its Production Data Query, through Aug 2026: Texas files production by lease, and where a lease lies in more than one county the split is the RRC's. Nothing here is estimated by Petrora. Wells from the RRC wellbore file and the permit record. Drilling permits from the RRC OGA049M master and daily daf420 files, rebuilt nightly into per-county figures; windows are on the date issued. Disposal from UIC permits and H-10 reports at the last settled month; earthquakes from the TexNet catalog inside the county's located-permit footprint.
