Vanco #6
Duval County · Lopez North (Lopez) field · Shut IN · Vertical
Vanco #6 (API 42-131-39295) is a well in Duval County operated by Rattlesnake Operating CO LLC, completed August 14, 2012 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued June 11, 2012, permitted to 3,500 ft.
It was permitted by Sanchez Oil & Gas Corporation and has since transferred to Rattlesnake Operating CO LLC on the wellbore schedule.
Completion filings report one formation top, including Mirando.
Its lease has reported 27.5K barrels of oil since August 2012, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
