Muir A #1H (API 42-123-32309) is a horizontal well in De Witt County operated by Devon Energy Production CO L.P., completed October 21, 2010 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 2010 and 2012, permitted to 12,567 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 2.59M barrels of oil and 8.41M mcf of gas since October 2010, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
