Andrews County · Fuhrman-Mascho field · Shut In · Vertical
Block 9 Fuhrman-Mascho Unit #151 (API 42-003-39315) is a well in Andrews County operated by Winn Operating LLC, completed October 15, 2004 and listed as shut in on the RRC schedule, shut in June 1, 2026.
The RRC has issued one drilling permit, issued August 26, 2004, permitted to 4,665 ft.
It was permitted by Thompson, J. Cleo and has since transferred to Winn Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 2.05M barrels of oil and 551K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 160 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Apr 29, 2008. 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.
