The RRC has issued one drilling permit (amended once), issued April 5, 1994, permitted to 10,250 ft.
It was permitted by Stephens, Autry C. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 390K barrels of oil and 803K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
