San Patricio County · Odem (6160) field · Vertical
Welder J.F. Unit #C 34 (API 42-409-30244) is a well in San Patricio County operated by Chevron U. S. A. Inc., completed January 23, 1974.
The RRC has issued 2 drilling permits between 1990 and 2001, permitted to 6,315 ft.
It was permitted by Energen Resources Corporation and has since transferred to Chevron U. S. A. Inc. on the wellbore schedule.
Its 4 leases have reported 616K barrels of oil and 7.42M mcf of gas since January 1993, last reporting in July 2026. The leases carry 36 wells, so these are lease totals, not this well alone.
