The RRC has issued one drilling permit, issued August 9, 1983, permitted to 5,100 ft.
It was permitted by Winchester Energy Company and has since transferred to D C Oil Company Inc. on the wellbore schedule.

Its lease has reported 868K barrels of oil and 821K mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
