The RRC has issued one drilling permit, issued March 16, 1988, permitted to 12,300 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 286K barrels of oil and 806K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
