Lee County · Giddings (Austin Chalk-3) field · Horizontal
Mildred #1RE (API 42-287-31072) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed January 14, 1982.
The RRC has issued 3 drilling permits between 1981 and 2005, permitted to 9,000 ft.
It was permitted by U. S. Operating, Inc. 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 30.2K barrels of oil and 733K 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.
