Mann50 #1 (API 42-461-35311) is a well in Upton County operated by Diamondback E&P LLC, completed June 28, 2007 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit, issued April 2, 2007, permitted to 10,275 ft.
It was permitted by Henry Petroleum LP and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including T. Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 91.6K barrels of oil and 327K mcf of gas since June 2007, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 27, 2010. Cased hole. 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.
