The RRC has issued one drilling permit, issued October 12, 2001, permitted to 2,300 ft.
It was permitted by Reilly, K. L. and has since transferred to KO Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Nacatoch, Pecan Gap, Wolf City.
Its lease has reported 20K barrels of oil since November 2001, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
