Diller Mildred A #20 (API 42-417-37471) is a plugged well in Shackelford County, plugged January 22, 2014, last operated by Quantum Investments.
The RRC has issued one drilling permit, issued January 29, 1991, permitted to 1,000 ft.
It was permitted by G-3 Oil and has since transferred to Quantum Investments on the wellbore schedule.
Completion filings report one formation top, including Frye.
Its lease has reported 16.1K barrels of oil and 56 mcf of gas since January 1993, last reporting in July 2026. The lease carries 27 wells, so these are lease totals, not this well alone.
Operator of record
