Armstrong-Munson Unit #1 (API 42-149-32595) is a horizontal well in Fayette County operated by Magnolia Oil & Gas Operating LLC, completed May 2, 1992 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 13, 1992, permitted to 10,022 ft.

It was permitted by Coastal Oil & Gas Corporation and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Midway, Navarro, Tyler, Pecan Gap.

Its 2 leases have reported 492K barrels of oil and 3.69M 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.

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