The RRC has issued one drilling permit (amended once), issued October 13, 2022, permitted to 8,500 ft.
It was permitted by Saddleback Exploration, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 801K barrels of oil and 1.31M mcf of gas since September 2018, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
