The RRC has issued one drilling permit, issued March 6, 1980, permitted to 6,660 ft.
It was permitted by Amoco Production Company and has since transferred to Unit Petroleum Company on the wellbore schedule.
Its lease has reported 2.69K barrels of oil and 37.4K mcf of gas since January 1993, last reporting in March 1996. The lease carries 3 wells, so these are lease totals, not this well alone.
