The RRC has issued one drilling permit (amended once), issued October 13, 2011, permitted to 11,700 ft.
It was permitted by Athlon Holdings LP and has since transferred to Ovintiv USA Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Strawn, Atoka.
Its lease has reported 17.1K barrels of oil and 36.4K mcf of gas since May 2010, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 31, 2014. Cased hole. 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.
