The RRC has issued one drilling permit, issued May 26, 1982, permitted to 3,255 ft.
It was permitted by Winn Exploration/Dulce Company and has since transferred to Mcday Energy Corp. on the wellbore schedule.

Its lease has reported 51.2K barrels of oil and 1.78K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
