Welder J. F. Unit #B 8
San Patricio County · Odem (Massive Frio) field · Temp Abandoned · Vertical
Welder J. F. Unit #B 8 (API 42-409-03791) is a well in San Patricio County operated by Iron Jaw Operating LLC, completed December 1, 1999 and listed as temp abandoned on the RRC schedule, shut in October 1, 2016.
The RRC has issued 3 drilling permits (amended once) between 1979 and 1995, permitted to 6,818 ft.
It was permitted by Smith Production Inc. and has since transferred to Iron Jaw Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including 6700 -A-, 6700 Stringer, 6700 -B-.
Its 3 leases have reported 616K barrels of oil and 7.67M mcf of gas since January 1993, last reporting in July 2026. The leases carry 32 wells, so these are lease totals, not this well alone.
Operator of record
