Sealy-Smith Foundation -A- #20 (API 42-495-05277) is a well in Winkler County operated by Hilcorp Energy Company, completed May 6, 1992.
The RRC has issued 3 drilling permits between 1987 and 1999, permitted to 13,600 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 10 formation tops, including Queen, Glorieta, Clear Fork, U. Clearfork.
Its 3 leases have reported 2.64M barrels of oil and 17.2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 39 wells, so these are lease totals, not this well alone.
