Vaquillas Ranch A8 #59 (API 42-479-34571) is a well in Webb County operated by Hilcorp Energy Company, completed March 1, 1998 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1987 and 1997, permitted to 9,650 ft.
It was permitted by Conoco Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Carrizo, Wilcox, Base Of Lwr. Wilcox, Lobo Interval.
Its 2 leases have reported 165K barrels of oil and 7.52M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
