It was permitted by Ensign Natural Resources II LLC and has since transferred to Marathon Oil EF LLC on the wellbore schedule.

Its lease has reported 15M barrels of oil and 18.4M mcf of gas since November 2010, last reporting in July 2026. The lease carries 60 wells, so these are lease totals, not this well alone.
