The RRC has issued one drilling permit (amended once), issued March 8, 2014, permitted to 7,200 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 13.9M barrels of oil and 40.3M mcf of gas since January 1993, last reporting in July 2026. The lease carries 496 wells, so these are lease totals, not this well alone.
