Wharton County · Magnet Withers field · Vertical
Cockburn H. C. #147 (API 42-481-34985) is a well in Wharton County operated by Orx Resources L.L.C., completed October 17, 2008.
The RRC has issued 3 drilling permits between 2008 and 2016, permitted to 8,000 ft.
It was permitted by White Oak Operating Company LLC and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 10 formation tops, including Miocene (undifferentiated), Frio, Anahuac, Boling Dome - Disposal.
Its 3 leases have reported 6.54M barrels of oil and 5.84M 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.
