The RRC has issued one drilling permit (amended once), issued March 16, 2012, permitted to 10,911 ft.
It was permitted by Chesapeake Operating, L.L.C. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 4.74M barrels of oil and 8.35M mcf of gas since December 2010, last reporting volume in April 2026. The lease carries 39 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Nov 6, 2018. Mud log. 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.
