It was permitted by Forest Oil Corporation and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 143K barrels of oil and 178K mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
