Munn-B 1125 #4 (API 42-451-31414) is a well in Tom Green County operated by Hibernia Resources IV LLC, completed April 20, 2001.
The RRC has issued 3 drilling permits between 1984 and 2001, permitted to 6,750 ft.
It was permitted by Merit Energy Company and has since transferred to Hibernia Resources IV LLC on the wellbore schedule.
Completion filings report 11 formation tops, including San Angelo, Coleman Junction, Swastika, Swastika Sand.
Its 3 leases have reported 79.9K barrels of oil and 2.51M mcf of gas since January 1993, last reporting in July 2026. The leases carry 14 wells, so these are lease totals, not this well alone.
