Swenson C #1H (API 42-311-34996) is a horizontal well in Mcmullen County operated by Trinity Operating (Usg) LLC, completed November 7, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 26, 2012, permitted to 11,252 ft.

It was permitted by Comstock Oil & Gas, LP and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Olmos, Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 742K barrels of oil and 1.49M mcf of gas since September 2012, last reporting in July 2026. The lease carries 5 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.
