Ketchum MT. (Clear Fork) Unit #4813 (API 42-235-31788) is a well in Irion County operated by Apache Corporation, completed February 15, 1990 and listed as shut in on the RRC schedule, shut in March 1, 2025.
The RRC has issued 2 drilling permits between 1981 and 1989, permitted to 6,400 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Grayburg, San Andres, San Angelo, Clear Fork.
Its 2 leases have reported 2.45M barrels of oil and 1.52M mcf of gas since January 1993, last reporting in July 2026. The leases carry 98 wells, so these are lease totals, not this well alone.
