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

Its lease has reported 9.38M barrels of oil and 8.35M mcf of gas since July 1996, last reporting in July 2026. The lease carries 97 wells, so these are lease totals, not this well alone.
