Cheek Unit A 28-21 #1AH (API 42-227-38928) is a horizontal well in Howard County operated by Apache Corporation, completed March 14, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 30, 2016, permitted to 8,500 ft.
It was permitted by Callon Petroleum Operating CO and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 12 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 1.36M barrels of oil and 2.24M mcf of gas since March 2017, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
