Upton County · Spraberry (Trend Area) field · Vertical
Mann52 #2 (API 42-461-36047) is a plugged well in Upton County, plugged November 16, 2017, last operated by Cog Operating LLC.
The RRC has issued one drilling permit, issued August 20, 2008, permitted to 10,800 ft.
It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including T. Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 66.5K barrels of oil and 321K mcf of gas since December 2008, with no volume in the three years through 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 Nov 18, 2011. 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.
