On schedule

McMullen County · Eagleville (Eagle Ford-1) field · Producing · Horizontal

Rancho Tres Hijos B #1H (API 42-311-34581) is a horizontal well in Mcmullen County operated by Trinity Operating (Usg) LLC, completed April 8, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 23, 2011, permitted to 10,887 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 97.8K barrels of oil and 345K mcf of gas since January 2013, last reporting volume in August 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
