South Lopez Unit #6-1
Webb County · Lopez field · Vertical
South Lopez Unit #6-1 (API 42-479-01017) is a plugged well in Webb County, plugged February 24, 1993, last operated by Mirando Resource L.L.C..
The RRC has issued one drilling permit, issued October 21, 1977, permitted to 2,236 ft.
It was permitted by Tesoro Petroleum Corporation and has since transferred to Mirando Resource L.L.C. on the wellbore schedule.
Completion filings report one formation top, including First Mirando.
Its lease has reported 162K barrels of oil and 39 mcf of gas since January 1993, last reporting in March 2008. The lease carries 69 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Tesoro Petroleum Corporation; the EWA schedule now lists a different operator.
