The RRC has issued one drilling permit (amended twice), issued July 22, 2010, permitted to 11,880 ft.
It was permitted by Sem Operating Company LLC and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Austin Chalk, Sub-Clarksville, Woodbine, Buda.
Its 4 leases have reported 131K barrels of oil and 737K mcf of gas since August 2012, last reporting volume in April 2026. The leases carry 4 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Aug 24, 2015. 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.
