Polk 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 Aug 2026, so that month and the twelve-month totals will rise.

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.
