It was permitted by Chesapeake Operating, Inc. and has since transferred to Exco Operating Company LP on the wellbore schedule.

Its lease has reported 343K barrels of oil and 851K mcf of gas since July 2011, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
