Welder J. F. #B 12 (API 42-409-03762) is a plugged well in San Patricio County, plugged February 17, 2022, last operated by Gtg Operating LLC.
The RRC has issued one drilling permit (amended once), issued December 14, 1995, permitted to 5,542 ft.
It was permitted by Smith Production Inc. and has since transferred to Gtg Operating LLC on the wellbore schedule.
Its 2 leases have reported 60.4K barrels of oil and 1.25M 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.
