Usher Unit #1
San Patricio County · Aransas Pass (6900) field · Vertical
Usher Unit #1 (API 42-409-02426) is a well in San Patricio County operated by Total Minatome Corporation, completed February 1, 1966.
The RRC has issued one drilling permit, issued February 25, 1982, permitted to 7,263 ft.
It was permitted by Brinkerhoff Oil Company and has since transferred to Total Minatome Corporation on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its lease has reported 211K barrels of oil and 1.31K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 957K barrels injected in the 12 months reported through January 2026.
