Holden-Moore Unit #3HA (API 42-331-35006) is a horizontal well in Milam County operated by Magnolia Oil & Gas Operating LLC, completed August 1, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued January 18, 2018, permitted to 6,000 ft.

It was permitted by Treadstone Energy Prtnr OP, LLC and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Navarro, Pecan Gap, Giddings (Austin Chalk-3), Edwards.

Its lease has reported 1.56M barrels of oil and 1.29M mcf of gas since November 1997, last reporting in July 2026. The lease carries 3 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.
