It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 18.3M barrels of oil and 12.3M mcf of gas since January 1993, last reporting in July 2026. The lease carries 622 wells, so these are lease totals, not this well alone.
