The RRC has issued one drilling permit, issued December 31, 1980, permitted to 9,500 ft.
It was permitted by Brown, H. L., JR. and has since transferred to Lario Oil & Gas Company on the wellbore schedule.
Its lease has reported 98.5K barrels of oil and 125K mcf of gas since January 1993, last reporting in May 2022. The lease carries 4 wells, so these are lease totals, not this well alone.
