The RRC has issued one drilling permit, issued July 11, 1979, permitted to 8,600 ft.
It was permitted by Mwj Producing Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Its lease has reported 35.5K barrels of oil and 57.5K mcf of gas since January 1993, last reporting in March 2018. The lease carries 2 wells, so these are lease totals, not this well alone.
