Wolf Unit #3HA
Milam County · Giddings (Austin Chalk-3) field · Producing · Horizontal
Wolf Unit #3HA (API 42-331-35051) is a horizontal well in Milam County operated by Magnolia Oil & Gas Operating LLC, completed April 19, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued November 5, 2018, permitted to 7,000 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 5 formation tops, including Midway, Navarro, Pecan Gap, Gidding (Austin Chalk-3).
Its lease has reported 1.09M barrels of oil and 1.55M mcf of gas since February 1998, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
