West JO-Mill Unit #614 (API 42-033-31710) is a well in Borden County operated by JO Mill Oil Company LLC, completed July 7, 1998 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 27, 1998, permitted to 7,700 ft.

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

Completion filings report 6 formation tops, including Base Clfk, Upr. Clfk, Lwr. Clfk, Zone 1.

Its lease has reported 7.68M barrels of oil and 2.74M mcf of gas since January 1993, last reporting in July 2026. The lease carries 103 wells, so these are lease totals, not this well alone.
