The RRC has issued one drilling permit, issued October 18, 1983, permitted to 2,600 ft.
It was permitted by Cox, Robert G. & Associates,Inc. and has since transferred to Clark Oil CO. on the wellbore schedule.

Its lease has reported 20.2K barrels of oil and 235 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.
