Atascosa 601 Unit #1H (API 42-013-34431) is a horizontal well in Atascosa County operated by Texas American Resources Company, completed February 27, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued October 3, 2011, permitted to 8,598 ft.

It was permitted by Cinco Natural Resources Corp. and has since transferred to Texas American Resources Company on the wellbore schedule.

Completion filings report 3 formation tops, including Olmos, Austin Chalk, Eagle Ford.

Its lease has reported 405K barrels of oil and 352K mcf of gas since February 2012, last reporting in July 2026. The lease carries 3 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.
