McLennan 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.
