Carroll-Biering Unit #1 (API 42-041-31473) is a horizontal well in Brazos County operated by Magnolia Oil & Gas Operating LLC, completed October 1, 1996 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended twice) between 1990 and 1995, permitted to 12,692 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Midway, Navarro, Pecan Gap, Austin Chalk.
Its 2 leases have reported 24.5K barrels of oil and 1.49M mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
