It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Its lease has reported 949K barrels of oil and 3.36M mcf of gas since December 2023, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
