The RRC has issued 2 drilling permits (amended twice) between 1984 and 2010, permitted to 6,002 ft.
It was permitted by Newman Cubed, Inc. and has since transferred to Cambrian Management Ltd. on the wellbore schedule.

Its 3 leases have reported 4.46K barrels of oil and 61.3K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
