The RRC has issued one drilling permit, issued March 21, 2014, permitted to 3,200 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 Rustler, Yates, Seven Rivers, Grayburg.
Its lease has reported 153K barrels of oil and 695K mcf of gas since April 2013, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
