Allan Marburger #5H
Bastrop County · Giddings (Austin Chalk-3) field · Producing · Horizontal
Allan Marburger #5H (API 42-021-31607) is a horizontal well in Bastrop County operated by Magnolia Oil & Gas Operating LLC, completed December 16, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 8, 2008, permitted to 7,500 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 one formation top, including Austin Chalk.
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.
