Webb County · Cole West field · Vertical
De Benavides Rosa V. #21 (API 42-479-31780) is a plugged well in Webb County, plugged July 27, 2007, last operated by Killam Oil CO. Ltd..
The RRC has issued one drilling permit, issued August 3, 1977, permitted to 2,400 ft.
It was permitted by Killam & Hurd, Ltd. and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Its lease has reported 45.1K barrels of oil and 21 mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 34 wells, so these are lease totals, not this well alone.
