It was permitted by Questa Oil & Gas CO. and has since transferred to Rhr Oil & Gas LLC on the wellbore schedule.

Its lease has reported 26.6K barrels of oil and 569 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
