It was permitted by Indian Wells Oil Company and has since transferred to Breitburn Operating L.P. on the wellbore schedule.

Its lease has reported 13.7K barrels of oil and 479K mcf of gas since January 1993, last reporting in March 2015. The lease carries 7 wells, so these are lease totals, not this well alone.
