It was permitted by Patriot Resources, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Its lease has reported 17.1M barrels of oil and 28.5M mcf of gas since December 2006, last reporting volume in April 2026. The lease carries 154 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 18, 2011. 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.
