The RRC has issued one drilling permit (amended once), issued February 25, 1992, permitted to 7,575 ft.
It was permitted by Oryx Energy Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.

Its lease has reported 634K barrels of oil and 1.22M mcf of gas since January 1993, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
