Irion County · Ketchum Mt. (Clear Fork) field · Producing · Vertical
Ketchum MT. (Clear Fork) Unit #54 4 (API 42-235-31790) is a well in Irion County operated by Apache Corporation, completed August 10, 1981 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 3, 1981, permitted to 4,650 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Apache Corporation on the wellbore schedule.
Its lease has reported 2.45M barrels of oil and 1.52M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 98 wells, so these are lease totals, not this well alone.
