The RRC has issued 2 drilling permits between 1977 and 1978, permitted to 9,810 ft.
It was permitted by Shell Oil Company and has since transferred to Formentera Operations LLC on the wellbore schedule.
Its lease has reported 41.4K barrels of oil and 270K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
