Herrera Gregorio #11 (API 42-311-35932) is a well in Mcmullen County operated by Atlas Operating LLC, completed June 3, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 22, 2014, permitted to 6,150 ft.

It was permitted by Wynn-Crosby Operating, Ltd. and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Anacacho, Austin Chalk, Buda, Catahoula.

Its lease has reported 65.9K barrels of oil since February 2006, last reporting in July 2026. The lease carries 6 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.
