Casselman40 #9 (API 42-329-39482) is a well in Midland County operated by Apache Corporation, completed September 10, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 16, 2014, permitted to 11,760 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 Santa Rosa, Yates, Seven Rivers, Atoka.
Its lease has reported 3.1M barrels of oil and 10.4M mcf of gas since July 2008, last reporting volume in April 2026. The lease carries 31 wells, so these are lease totals, not this well alone.
