Welder E. H. -C- #165 (API 42-409-31856) is a well in San Patricio County operated by Mcgowan Working Partners Inc., completed May 4, 1995 and listed as shut in on the RRC schedule, shut in January 1, 1998.

The RRC has issued 3 drilling permits between 1983 and 1987, permitted to 7,212 ft.

It was permitted by Marathon Oil Company and has since transferred to Mcgowan Working Partners Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Miocene (undifferentiated), Anahuac, Frio.

Its lease has reported 763K barrels of oil and 1.16M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 51 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
