Cockburn H. C. #71 (API 42-481-03370) is a plugged well in Wharton County, plugged April 8, 2022, last operated by Orx Resources L.L.C..
The RRC has issued 3 drilling permits between 1981 and 2008, permitted to 6,312 ft.
It was permitted by Milagro Exploration, LLC and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Miocene (undifferentiated), Het, Frio.
Its 3 leases have reported 6.54M barrels of oil and 6.32M mcf of gas since January 1993, last reporting in July 2026. The leases carry 145 wells, so these are lease totals, not this well alone.
