Silver City Unit #4AH (API 42-227-39411) is a horizontal well in Howard County operated by Apache Corporation, completed November 17, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued December 20, 2017, permitted to 8,900 ft.
It was permitted by Callon Petroleum Operating CO and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Seven Rivers, San Andres, Glorieta.
Its lease has reported 1.85M barrels of oil and 3.53M mcf of gas since July 2016, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
