Sealy & Smith Unit #11
Winkler County · Halley (Penn.) field · Vertical
Sealy & Smith Unit #11 (API 42-495-04472) is a well in Winkler County operated by Atlantic Richfield CO., completed June 1, 1961.
The RRC has issued one drilling permit, issued August 10, 1995, permitted to 5,171 ft.
It was permitted by Anadarko Petroleum Corp. and has since transferred to Atlantic Richfield CO. on the wellbore schedule.
Its 2 leases have reported 608K barrels of oil and 2.38M mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
