Cockburn H.C. #146
Wharton County · Magnet Withers (Frio Cons.) field · Vertical
Cockburn H.C. #146 (API 42-481-34839) is a well in Wharton County operated by Orx Resources L.L.C., completed July 8, 2014.
The RRC has issued 2 drilling permits between 2006 and 2021, permitted to 7,700 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 11 formation tops, including Miocene (undifferentiated), Het, Frio, Anahuac.
Its 3 leases have reported 6.99M barrels of oil and 6.59M mcf of gas since January 1993, last reporting in July 2026. The leases carry 165 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit; TexNet located 0 M2+ earthquakes within 10 km over the last two years.
