The RRC has issued one drilling permit, issued August 5, 1986, permitted to 5,865 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Flint Oak Energy LLC on the wellbore schedule.

Its lease has reported 250K barrels of oil and 20.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 47 wells, so these are lease totals, not this well alone.
