Koehler Frank #2 (API 42-055-31172) is a plugged well in Caldwell County, plugged May 3, 2018, last operated by Eagle Ford Oil CO. Inc..

The RRC has issued one drilling permit, issued July 30, 1979, permitted to 2,500 ft.

It was permitted by Burr Oil CO. and has since transferred to Eagle Ford Oil CO. Inc. on the wellbore schedule.

Its lease has reported 1.09K barrels of oil and 34 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.
