It was permitted by Eclipse Oil & Gas, Inc. and has since transferred to Simpson Operating Services LP on the wellbore schedule.

Its lease has reported 55.2K barrels of oil and 138K mcf of gas since January 1999, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
