Diana 149 A #3 (API 42-461-36256) is a well in Upton County operated by Firebird Energy II LLC, completed April 12, 2009 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 22, 2009, permitted to 10,265 ft.
It was permitted by Cog Operating LLC and has since transferred to Firebird Energy II LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 116K barrels of oil and 509K mcf of gas since August 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 Feb 21, 2012. 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.
