Shafer C. W. Account 2 #27 (API 42-115-32735) is a well in Dawson County operated by JO Mill Oil Company LLC, completed December 8, 1992.

The RRC has issued one drilling permit, issued October 26, 1992, permitted to 7,720 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.

It holds an active disposal or injection permit, with 106K barrels injected in the 12 months reported through August 2025.
