Shafer C. W. Account 2 #31 (API 42-115-32799) is a well in Dawson County operated by JO Mill Oil Company LLC, completed June 7, 2023 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued December 23, 1993, permitted to 7,770 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 1.98M barrels of oil and 933K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
