The RRC has issued one drilling permit, issued March 9, 1979, permitted to 6,300 ft.
It was permitted by Lake Ronel Oil Company and has since transferred to Xto Energy Inc. on the wellbore schedule.

Its lease has reported 72.7K barrels of oil and 144 mcf of gas since January 1993, last reporting in April 2010. The lease carries 10 wells, so these are lease totals, not this well alone.
