The RRC has issued one drilling permit, issued November 23, 1983, permitted to 5,150 ft.
It was permitted by MR Oil Company and has since transferred to M T M Oil on the wellbore schedule.

Its lease has reported 10.2K barrels of oil and 12.9K 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.
