RRC COUNTY FIGURES · NO. 119 IN OIL AND NO. 29 IN GAS OF 219 PRODUCING TEXAS COUNTIES

Leon County oil and gas production

RRC COUNTY FIGURES · THROUGH AUG 2026

Texas operators report production by lease, and the Railroad Commission totals it by county. Where a lease lies in more than one county, the split between them is the RRC's. Oil includes condensate; gas includes casinghead gas. Leases are still filing for Jul 2026 and Aug 2026, so those months and the twelve-month totals will rise.

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.
