The RRC has issued one drilling permit, issued September 25, 1990, permitted to 5,402 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Texland Petroleum L.P. on the wellbore schedule.

Its lease has reported 888K barrels of oil and 139K mcf of gas since January 1993, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 175K barrels injected in the 12 months reported through November 2025.
