Spraberry Deep Unit #408A (API 42-115-32023) is a plugged well in Dawson County, plugged April 8, 2002, last operated by JO Mill Oil Company LLC.

The RRC has issued one drilling permit, issued May 15, 1984, permitted to 6,800 ft.

It was permitted by Texaco Inc. and has since transferred to JO Mill Oil Company LLC on the wellbore schedule.

Completion filings report 3 formation tops, including San Andres, Spraberry, Zone "F".

Its lease has reported 1.25M barrels of oil and 342K mcf of gas since January 1993, last reporting in July 2026. The lease carries 54 wells, so these are lease totals, not this well alone.
