It was permitted by O'Leary'S Oil & Gas Inc. and has since transferred to M & K Operating LLC on the wellbore schedule.

Its lease has reported 1.48K barrels of oil and 21.7K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
