Mcelroy Ranch #10 (API 42-461-02259) is a well in Upton County operated by Apache Corporation, completed August 14, 1995 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1988 and 1995, permitted to 12,498 ft.
It was permitted by Arco Permian and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Yates, San Andres, Spraberry, Pennsylvanian.
Its 2 leases have reported 54.2K barrels of oil and 6.07M mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
