Allan Marburger #4RE (API 42-021-31600) is a plugged horizontal well in Bastrop County, plugged April 13, 2018, last operated by Magnolia Oil & Gas Operating LLC.
The RRC has issued one drilling permit (amended twice), issued April 11, 2008, permitted to 7,400 ft.
It was permitted by Geosouthern Energy Corporation and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Austin Chalk, Buda.
Its lease has reported 194K barrels of oil and 115K mcf of gas since November 2007, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
