It was permitted by Silverbow Resources Oper, LLC and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 417K barrels of oil and 1.5M mcf of gas since January 2020, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
