Donnell B #1H (API 42-311-34584) is a horizontal well in Mcmullen County operated by Trinity Operating (Usg) LLC, completed June 4, 2023 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued June 24, 2011, permitted to 10,500 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 518K barrels of oil and 476K mcf of gas since April 2012, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
