The RRC has issued one drilling permit, issued September 11, 2002, permitted to 2,600 ft.
It was permitted by C. M. Oil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 25.7K barrels of oil and 110 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
