Volumes are lease totals as reported to RRC; a lease that spans county lines is listed in each county it reports in. Leases below our page threshold (100,000 BBL of liquids or 1,000,000 MCF of gas in 12 months) are in the RRC Production Data Query. Back to Gaines County.
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.
