The RRC has issued one drilling permit, issued October 19, 2006, permitted to 7,000 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Judkins, San Angelo, Ellenburger.
Its lease has reported 687 barrels of oil and 535 mcf of gas since November 2005, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 2.54M barrels injected in the 12 months reported through June 2025.
