It was permitted by Blackbrush O & G, LLC and has since transferred to Caturus Energy LLC on the wellbore schedule.

Its lease has reported 1.26M barrels of oil and 5.68M mcf of gas since May 2007, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
