Cockburn H. C. #138
Wharton County · Magnet Withers field · Temp Abandoned · Vertical
Cockburn H. C. #138 (API 42-481-33134) is a well in Wharton County operated by Orx Resources L.L.C., completed March 5, 2010 and listed as temp abandoned on the RRC schedule, shut in November 1, 2017.
The RRC has issued one drilling permit, issued January 22, 1988, permitted to 6,100 ft.
It was permitted by Exxon Corp. and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 2 formation tops, including Marginulina 1, Marginulina 2.
Its 2 leases have reported 6.54M barrels of oil and 5.88M mcf of gas since January 1993, last reporting in July 2026. The leases carry 144 wells, so these are lease totals, not this well alone.
