Check these figures in the RRC Production Data Query (Specific Lease Query: district 01, lease 16012). Production is reported per lease, so a lease with several wells is not split by well.

Source: Texas Railroad Commission (data sets, Production Data Query). Data date: RRC Production Data Query dump, extract dated Sep 18, 2026; production through Jul 2026. Jun 2026 and Jul 2026 are provisional: operators file late and amend, so these months usually rise in later releases. Oil = crude oil + condensate (BBL); gas = gas-well gas + casinghead gas (MCF), as reported to RRC. Methodology.
