The RRC has issued one drilling permit, issued August 21, 1986, permitted to 1,200 ft.
It was permitted by Enduro Oil Company Inc. and has since transferred to Texas Secondary Oil Corporation on the wellbore schedule.
Completion filings report one formation top, including Pettus.
Its lease has reported 415K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
