The RRC has issued one drilling permit, issued July 20, 2004, permitted to 7,825 ft.
It was permitted by Range Production Company and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Cisco, Canyon.
Its lease has reported 1M barrels of oil and 35.1M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 125 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 22, 2008. Density, Gamma ray, 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.
