Wally A1 #21H (API 42-475-37946) is a horizontal well in Ward County operated by Apache Corporation, completed February 23, 2020 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 26, 2019, permitted to 12,500 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 Rustler, Clear Fork, Delaware, Glorieta.
Its lease has reported 1.41M barrels of oil and 2.09M mcf of gas since February 2020, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
