The RRC has issued one drilling permit, issued August 4, 2016, permitted to 9,000 ft.
It was permitted by SN Operating, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Midway, Escondido, Olmos, San Miguel.
Its lease has reported 368K barrels of oil and 157K mcf of gas since December 2016, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
