Casselman4 #5 (API 42-329-35964) is a well in Midland County operated by Apache Corporation, completed May 5, 2009 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 18, 2008, permitted to 11,000 ft.
It was permitted by Henry Resources LLC and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 2.65M barrels of oil and 6.48M mcf of gas since February 2008, last reporting in July 2026. The lease carries 34 wells, so these are lease totals, not this well alone.
