Webb County · Vaquillas Ranch (Lobo Cons.) field · Producing · Vertical
Vaquillas Ranch CO. Ltd #45 (API 42-479-35529) is a well in Webb County operated by Hilcorp Energy Company, completed July 24, 1996 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1992 and 1996, permitted to 10,009 ft.
It was permitted by Conoco Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including Queen City, Wilcox, Lobo Unconformity, Wills Point.
Its 2 leases have reported 15.2K barrels of oil and 999K 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.
