The RRC has issued one drilling permit, issued November 20, 2017, permitted to 5,102 ft.

It was permitted by Denbury Onshore, LLC and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Its lease has reported 26.7M barrels of oil and 61.4M mcf of gas since January 1993, last reporting in July 2026. The lease carries 664 wells, so these are lease totals, not this well alone.
