Swenson #1H (API 42-311-34308) is a horizontal well in Mcmullen County operated by Trinity Operating (Usg) LLC, completed April 9, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued November 18, 2010, permitted to 11,152 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 5 formation tops, including Anacacho, Austin Chalk, Buda, Eagle Ford.

Its lease has reported 1.32M barrels of oil and 2.82M mcf of gas since April 2011, last reporting volume in August 2026. The lease carries 8 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.
