The RRC has issued one drilling permit, issued October 5, 1983, permitted to 7,650 ft.
It was permitted by Exxon Corp. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.

Its lease has reported 278K barrels of oil and 487K mcf of gas since January 1993, last reporting in July 2026. The lease carries 35 wells, so these are lease totals, not this well alone.
