The RRC has issued 2 drilling permits between 1998 and 2002, permitted to 4,750 ft.
It was permitted by Pure Resources, L.P. and has since transferred to Aghorn Operating Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Ruslter, Rustler, Yates, Seven Rivers.
Its lease has reported 3.1M barrels of oil and 1.34M mcf of gas since January 1993, last reporting in July 2026. The lease carries 119 wells, so these are lease totals, not this well alone.
