Isenhower #1 (API 42-059-33752) is a plugged well in Callahan County, plugged February 18, 2011, last operated by Clausen A. G..

The RRC has issued one drilling permit, issued May 18, 1982, permitted to 500 ft.

It was permitted by A.E.N. Energy, Inc. and has since transferred to Clausen A. G. on the wellbore schedule.

Completion filings report one formation top, including Cook Sand.

Its lease has reported 9.76K barrels of oil and 59 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
