JO-Mill Unit #6412A (API 42-033-31563) is a well in Borden County operated by JO Mill Oil Company LLC, completed September 9, 2025 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued July 6, 1993, permitted to 7,440 ft.

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

Completion filings report 3 formation tops, including Yates, San Andres, Spraberry.

Its lease has reported 46.1M barrels of oil and 22.1M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 487 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 60.6K barrels injected in the 12 months reported through August 2025.
