Koesler Mary #25 (API 42-097-33857) is a plugged well in Cooke County, plugged June 1, 2023, last operated by Nhrg Inc.

The RRC has issued one drilling permit, issued December 8, 2006, permitted to 2,000 ft.

It was permitted by Dsb Energy, LLC and has since transferred to Nhrg Inc on the wellbore schedule.

Its lease has reported 6.05K barrels of oil and 86 mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
