The RRC has issued one drilling permit (amended once), issued January 7, 2013, permitted to 13,118 ft.
It was permitted by Marathon Oil EF LLC and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Its 2 leases have reported 221K barrels of oil and 1.16M mcf of gas since April 2013, last reporting volume in August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Jan 17, 2017. 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.
