The RRC has issued 2 drilling permits (amended twice) between 1989 and 1991, permitted to 7,450 ft.
It was permitted by Acock Engineering & Operating CO and has since transferred to Chesapeake Operating L.L.C. on the wellbore schedule.

Its lease has reported 25.7K barrels of oil and 22.6K mcf of gas since January 1993, last reporting in May 2018. The lease carries 2 wells, so these are lease totals, not this well alone.
