Sarah #4515 (API 42-461-35825) is a plugged well in Upton County, plugged May 13, 2025, last operated by SM Energy Company.
The RRC has issued one drilling permit (amended once), issued May 23, 2008, permitted to 12,000 ft.
It was permitted by Cog Operating LLC and has since transferred to SM Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including T.Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 671K barrels of oil and 2.52M mcf of gas since January 2008, last reporting volume in October 2025. The lease carries 16 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 29, 2013. Neutron. 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.
