The RRC has issued one drilling permit, issued December 1, 2011, permitted to 11,420 ft.
It was permitted by Berry Oil Comp. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 7.71M barrels of oil and 31M mcf of gas since August 2008, last reporting volume in April 2026. The lease carries 51 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 9, 2015. 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.
