Andrews County · Fuhrman-Mascho field · Shut In · Vertical
South Fuhrman Mascho Unit #577 (API 42-003-40567) is a well in Andrews County operated by Crescent Energy Operating LLC, completed September 8, 2008 and listed as shut in on the RRC schedule, shut in June 1, 2026.
The RRC has issued one drilling permit, issued June 25, 2008, permitted to 4,751 ft.
It was permitted by OK Arena Operating Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Rustler, Yates, Grayburg, San Andres.
Its lease has reported 3.1M barrels of oil and 3.46M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 179 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Jan 23, 2009. Cased hole, Density, 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.
