Gantt Unit #1 A
Lee County · Giddings (Austin Chalk-3) field · Producing · Horizontal
Gantt Unit #1 A (API 42-287-31835) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed August 5, 2005 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1985 and 2004, permitted to 10,000 ft.
It was permitted by Wcs Oil And Gas Corporation and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Pecan Gap, Austin Chalk, Eagle Ford.
Its lease has reported 69.6K barrels of oil and 2.71M mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
