Questions about Williamson County minerals
How do I look up my lease in Williamson County?
Find the RRC lease number on your check stub, then search it on our lease search or in the RRC Production Data Query using district and lease number. Without a number, open the RRC GIS viewer, go to Williamson County and click the well. Step by step: how to look up your lease on RRC.
Who are the top operators in Williamson County?
By oil-equivalent volume over the 12 months to Jul 2026: GENESIS WELL SERVICE (5,163 BBL oil, 0 MCF gas), P&F OPERATIONS, LLC (1,067 BBL oil, 0 MCF gas) and NORTH TEXAS ENERGY,INC. (310 BBL oil, 0 MCF gas). The full list is in the table above.
How are royalties calculated on Williamson County production?
A gross royalty is roughly (oil volume × oil price + gas volume × gas price) × your decimal interest. Your decimal is on your check stub or division order. County production in May 2026 was 478 BBL of oil; try your own lease in the royalty estimator. Severance tax and any deductions your lease allows reduce the check.
How do I sell mineral rights in Williamson County?
Start with the production history of your lease on its page here, then compare several offers on the same basis (price per net mineral acre or a multiple of monthly royalty). Recent permits in the county (0 so far this month) can matter to buyers. See how to sell mineral rights. We are not a buyer or broker.
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. RRC notes county-level figures are allocated estimates based on allowables and potentials.
