Midland County · Spraberry (Trend Area) field · Shut IN  · Horizontal

Casselman10 #21AH (API 42-329-42532) is a horizontal well in Midland County operated by Apache Corporation, completed October 23, 2018 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued May 16, 2018, permitted to 9,855 ft.

It was permitted by Callon Petroleum Operating CO and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 2.57M barrels of oil and 7.83M mcf of gas since July 2008, last reporting in July 2026. The lease carries 26 wells, so these are lease totals, not this well alone.
