Callahan County · Callahan County Regular field · Water Supply · Vertical
Isenhower #14 (API 42-059-36271) is a well in Callahan County operated by Clausen A. G., completed February 1, 2011 and listed as water supply on the RRC schedule.
The RRC has issued one drilling permit, issued February 1, 1993, 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.
Operator of record
Permitted by A.E.N. Energy, Inc.; the EWA schedule now lists a different operator.
