The RRC has issued one drilling permit, issued November 2, 2017, permitted to 8,000 ft.
It was permitted by Blackbeard Operating, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, Yates, Queen, Colby-Queen.
Its lease has reported 264K barrels of oil and 109K mcf of gas since September 2015, last reporting in July 2026. The lease carries 76 wells, so these are lease totals, not this well alone.
