The RRC has issued one drilling permit (amended once), issued October 30, 2008, permitted to 8,804 ft.
It was permitted by Bta Oil Producers, LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, U Spraberry, L Spraberry, Dean.
Its lease has reported 66.7K barrels of oil and 619K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 29, 2019. Neutron. 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.
