The RRC has issued one drilling permit (amended once), issued December 1, 2010, permitted to 6,587 ft.
It was permitted by Crimson Exploration Oper., Inc. and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.

Its lease has reported 162K barrels of oil and 871K mcf of gas since June 2011, last reporting volume in October 2024. The lease carries 2 wells, so these are lease totals, not this well alone.

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
2 logs loaded from the RRC's log index, the latest received Jan 13, 2015. 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.
