Welder J. F. Unit #20 (API 42-409-30089) is a well in San Patricio County operated by Energen Resources Corporation, completed March 11, 1970.

The RRC has issued one drilling permit, issued March 15, 1999, permitted to 6,800 ft.

It was permitted by Smith Production Inc. and has since transferred to Energen Resources Corporation on the wellbore schedule.

Completion filings report 2 formation tops, including 6700-A, 6700 Stringer.

Its 2 leases have reported 92.9K barrels of oil and 810K mcf of gas since January 1993, last reporting in July 2026. The leases carry 15 wells, so these are lease totals, not this well alone.
