Borden County · JO-Mill (Spraberry) field · Shut In · Horizontal
JO-Mill Unit #1430H (API 42-033-31410) is a horizontal well in Borden County operated by JO Mill Oil Company LLC, completed October 28, 2011 and listed as shut in on the RRC schedule, shut in November 1, 2026.
The RRC has issued 2 drilling permits between 1989 and 2010, permitted to 7,455 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to JO Mill Oil Company LLC on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Clear Fork, 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.
