The RRC has issued one drilling permit, issued November 19, 1985, permitted to 2,650 ft.
It was permitted by Ensource Inc. and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Queen, Grayburg.
Its lease has reported 36.1K barrels of oil and 30.9K mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
