Wharton County · Magnet Withers (Miocene 4200) field · Temp Abandoned · Vertical
Cockburn H. C. #109 (API 42-481-31261) is a well in Wharton County operated by Orx Resources L.L.C., completed August 12, 1994 and listed as temp abandoned on the RRC schedule, shut in April 1, 2007.
The RRC has issued 3 drilling permits (amended once) between 1978 and 2006, permitted to 6,303 ft.
It was permitted by Kcs Resources, Inc. and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 4 formation tops, including Anahuac, Margulina, Top Of Marginulina, Frio.
Its 2 leases have reported 6.54M barrels of oil and 6.01M 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.
