Llano -8a- #1WD (API 42-173-37110) is a well in Glasscock County operated by Hannathon Petroleum II LLC, completed September 16, 2015.
The RRC has issued one drilling permit, issued January 29, 2015, permitted to 15,000 ft.
It was permitted by Energen Resources Corporation and has since transferred to Hannathon Petroleum II LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its 2 leases have reported 235K barrels of oil and 569K mcf of gas since December 2011, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 1.86M barrels injected in the 12 months reported through January 2026.
