Sellers -66- #4 (API 42-431-31539) is a well in Sterling County operated by Winn Operating LLC, completed March 6, 1985 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued October 2, 1984, permitted to 8,700 ft.

It was permitted by Ogr Operating CO, Inc. and has since transferred to Winn Operating LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Clear Fork, Wolfcamp, Canyon, Strawn.

Its lease has reported 77.4K barrels of oil and 186K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
