The RRC has issued one drilling permit (amended once), issued February 16, 1989, permitted to 4,800 ft.
It was permitted by Buffum & Baker, Inc. and has since transferred to Exlco Inc. on the wellbore schedule.

Its lease has reported 15.6K barrels of oil and 19.4K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
