The RRC has issued one drilling permit, issued January 30, 1981, permitted to 9,800 ft.
It was permitted by Saxon Oil Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Its lease has reported 196K barrels of oil and 252K mcf of gas since January 1993, last reporting in November 2021. The lease carries 6 wells, so these are lease totals, not this well alone.
