DE Benavides Rosa V. -B- #50 W
Webb County · Cole West field · Vertical
De Benavides Rosa V. -B- #50 W (API 42-479-33559) is a plugged well in Webb County, plugged November 12, 1993, last operated by Killam Oil CO. Ltd..
The RRC has issued one drilling permit, issued February 22, 1983, permitted to 2,500 ft.
It was permitted by Petrorey Div. Killam & Hurd and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Completion filings report one formation top, including Mirando (Lopez) Sand.
Its lease has reported 3.21K barrels of oil and 20 mcf of gas since January 1993, last reporting in March 2008. The lease carries 15 wells, so these are lease totals, not this well alone.
