The RRC has issued one drilling permit, issued August 6, 1984, permitted to 2,700 ft.
It was permitted by Luling Oil & Gas Company, Inc. and has since transferred to Luling Well Service on the wellbore schedule.

Its lease has reported 199K barrels of oil and 632K mcf of gas since January 1993, last reporting in July 2026. The lease carries 39 wells, so these are lease totals, not this well alone.
