The RRC has issued one drilling permit, issued March 21, 2011, permitted to 10,990 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 475K barrels of oil and 1.02M mcf of gas since April 2001, last reporting volume in April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Dec 15, 2014. 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.
