The RRC has issued one drilling permit (amended once), issued May 19, 2008, permitted to 11,756 ft.
It was permitted by Samson Lone Star, LLC and has since transferred to Tgnr East Texas II LLC on the wellbore schedule.

Its 2 leases have reported 7.14K barrels of oil and 742K mcf of gas since August 2008, last reporting volume in April 2026. The leases carry 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 Aug 2, 2011. Density, Neutron, Resistivity. 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.
