The RRC has issued one drilling permit, issued March 17, 2005, permitted to 4,694 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 2 leases have reported 7.13M barrels of oil and 5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 249 wells, so these are lease totals, not this well alone.
