McMullen County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Rancho Tres Hijos B #4H (API 42-311-35512) is a horizontal well in Mcmullen County operated by Trinity Operating (Usg) LLC, completed February 25, 2014 and listed as producing on the RRC schedule, shut in May 1, 2026.
The RRC has issued one drilling permit (amended once), issued June 25, 2013, permitted to 10,904 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 6 formation tops, including Wilcox, Escondido, Olmos, Anacacho.
Its 2 leases have reported 147K barrels of oil and 554K mcf of gas since January 2013, last reporting volume in August 2026. The leases carry 6 wells, so these are lease totals, not this well alone.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
