The RRC has issued one drilling permit, issued September 6, 2011, permitted to 12,070 ft.

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

Its lease has reported 9.04M barrels of oil and 22.4M mcf of gas since February 2009, last reporting volume in April 2026. The lease carries 83 wells, so these are lease totals, not this well alone.

Well logs

1 log loaded from the RRC's log index, the latest received Apr 28, 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.
