It was permitted by Damco Energy Corporation and has since transferred to J & J Services Company on the wellbore schedule.

Its lease has reported 4.2K barrels of oil and 7.14K mcf of gas since January 1993, last reporting in August 2003. The lease carries 2 wells, so these are lease totals, not this well alone.
