The RRC has issued one drilling permit, issued September 13, 2019, permitted to 18,000 ft.
It was permitted by 1776 Energy Operators, LLC and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Its lease has reported 531K barrels of oil and 890K mcf of gas since December 2010, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
