The RRC has issued 2 drilling permits between 1991 and 2005, permitted to 11,500 ft.
It was permitted by Anadarko E&P Company LP and has since transferred to Chesapeake Operating L.L.C. on the wellbore schedule.

Its lease has reported 124K barrels of oil and 258K mcf of gas since January 1993, last reporting in October 2020. The lease carries 2 wells, so these are lease totals, not this well alone.
