It was permitted by Dunigan Petroleum, Inc. and has since transferred to Pendragon Oil CO. on the wellbore schedule.

Its lease has reported 239K barrels of oil and 163K mcf of gas since January 1993, last reporting in July 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
