De Witt County · Eagleville (Eagle Ford-2) field · Producing · Horizontal
Muir B #1H (API 42-123-32336) is a horizontal well in De Witt County operated by Devon Energy Production CO L.P., completed July 12, 2011 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2010 and 2012, permitted to 13,111 ft.
It was permitted by Geosouthern Energy Corporation and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.
Completion filings report 3 formation tops, including Pecan Gap, Austin Chalk, Eagle Ford.
Its 2 leases have reported 610K barrels of oil and 2.95M mcf of gas since December 2010, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
