Borden County · JO-Mill (Spraberry) field · Injection · Vertical
JO-Mill Unit #3422 (API 42-033-30417) is a well in Borden County operated by JO Mill Oil Company LLC, completed May 25, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 15, 1977, permitted to 7,320 ft.
It was permitted by Texaco Inc. and has since transferred to JO Mill Oil Company LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Redbed, Spraberry.
Its lease has reported 46.3M barrels of oil and 22.2M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 487 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 90.5K barrels injected in the 12 months reported through August 2026.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
