Midland County · Spraberry (Trend Area) field · Shut In · Horizontal
Casselman 8 Psa 1 #22MS (API 42-329-40387) is a horizontal well in Midland County operated by Apache Corporation, completed October 30, 2015 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued July 24, 2015, permitted to 8,670 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 483K barrels of oil and 1.45M mcf of gas since October 2015, last reporting volume in March 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Aug 28, 2018. Gamma ray. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
