The RRC has issued one drilling permit (amended once), issued January 27, 2010, permitted to 11,120 ft.
It was permitted by High Sky Partners LLC and has since transferred to Cog Operating LLC on the wellbore schedule.

Its lease has reported 441K barrels of oil and 1.96M mcf of gas since April 2010, last reporting volume in April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Sep 27, 2010. 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.
