The RRC has issued one drilling permit, issued August 12, 2014, permitted to 8,824 ft.
It was permitted by Laredo Petroleum, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 292K barrels of oil and 1.47M mcf of gas since May 2015, last reporting volume in 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 Oct 26, 2017. Cement bond. 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.
