The RRC has issued one drilling permit, issued December 31, 2018, permitted to 8,840 ft.
It was permitted by Diamondback E&P LLC and has since transferred to Satanta Oil Company on the wellbore schedule.

Its 3 leases have reported 2.89M barrels of oil and 14.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
