Webb County · Vaquillas Ranch (Lobo Cons.) field · Producing · Vertical
Vergara G. B. #10 (API 42-479-35891) 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 1993 and 1997, permitted to 10,643 ft.
It was permitted by Conoco Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including Queen City, Carrizo, Wilcox, Lobo Unconformity.
Its 2 leases have reported 43.1K barrels of oil and 2.72M mcf of gas since October 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
