Welder J. F. Unit #C 38 (API 42-409-30260) is a well in San Patricio County operated by Energen Resources Corporation, completed September 20, 1979.
The RRC has issued 3 drilling permits between 1979 and 1989, permitted to 6,813 ft.
It was permitted by Texaco Inc. and has since transferred to Energen Resources Corporation on the wellbore schedule.
Its 2 leases have reported 23.4K barrels of oil and 690K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
