It was permitted by Shell Western E&P Inc. and has since transferred to Apache Corporation on the wellbore schedule.

Its 3 leases have reported 41.7K barrels of oil and 244K mcf of gas since January 1993, last reporting in July 2026. The leases carry 14 wells, so these are lease totals, not this well alone.
