The RRC has issued 2 drilling permits between 1997 and 2008, permitted to 11,700 ft.
It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 11 formation tops, including Rustler, T/Salt, B/Salt, T/Delaware.
Its lease has reported 313K barrels of oil and 596K mcf of gas since January 1998, last reporting volume in September 2025. The lease carries 2 wells, so these are lease totals, not this well alone.
