Sealy & Smith Unit #4 (API 42-495-04468) is a plugged well in Winkler County, plugged September 6, 1995, last operated by Basin Oil & Gas Operating LLC.

The RRC has issued one drilling permit, issued January 21, 1986, permitted to 5,500 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Queen, Glorieta, Clear Fork.

Its lease has reported 262K barrels of oil and 648K mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
