Cockburn H.C. #105 (API 42-481-31010) is a well in Wharton County operated by Orx Resources L.L.C., completed May 24, 2010.
The RRC has issued 4 drilling permits between 1981 and 2012, permitted to 7,407 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 2 formation tops, including Anahuac, Frio.
Its 4 leases have reported 7.04M barrels of oil and 6.36M mcf of gas since January 1993, last reporting in July 2026. The leases carry 166 wells, so these are lease totals, not this well alone.
