Cockburn H.C. #161 (API 42-481-34968) is a well in Wharton County operated by Orx Resources L.L.C., completed April 15, 2014.
The RRC has issued 2 drilling permits between 2008 and 2014, permitted to 7,600 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 13 formation tops, including Marg, Marg 1, Marginulina, Frio.
Its 2 leases have reported 6.99M barrels of oil and 6.32M mcf of gas since January 1993, last reporting in July 2026. The leases carry 164 wells, so these are lease totals, not this well alone.
