Webb County · Vaquillas Ranch (Lobo Cons.) field · Vertical
Vaquillas Ranch-C #51 (API 42-479-33887) is a plugged well in Webb County, plugged July 1, 2008, last operated by Conocophillips Company.
The RRC has issued 2 drilling permits between 1984 and 1993, permitted to 12,900 ft.
It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 10 formation tops, including Carrizo, Wilcox, Bse Of Lower Wilcox, Walker Stray.
Its 2 leases have reported 154 barrels of oil and 79.6K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
