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.
