Brooks County · Ann Mag (8100 Frio) field · Vertical
Rupp #2 (API 42-047-31347) is a well in Brooks County operated by Atropos Exploration Company, completed May 14, 1987.
The RRC has issued 6 drilling permits (amended once) between 1984 and 1995, permitted to 8,900 ft.
It was permitted by Maguire Oil Company and has since transferred to Atropos Exploration Company on the wellbore schedule.
Completion filings report 7 formation tops, including 7150 D Marker, 7600 Frio, 7800, 7800 Frio.
Its 3 leases have reported 20.7K barrels of oil and 90.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
