Welder E. H. -C- #136 (API 42-409-01590) is a well in San Patricio County operated by Mcgowan Working Partners Inc., completed March 16, 2020 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 1982 and 1983, permitted to 6,154 ft.

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

Completion filings report one formation top, including Heep.

Its lease has reported 763K barrels of oil and 1.16M mcf of gas since January 1993, last reporting in July 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.
