Armstrong #1 (API 42-003-35365) is a plugged well in Andrews County, plugged September 2, 2011, last operated by Apache Corporation.

The RRC has issued 2 drilling permits between 1985 and 1986, permitted to 9,500 ft.

It was permitted by V-F Petroleum Inc. and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, Grayburg, San Andres, Wolfcamp.

Its 4 leases have reported 9.39M barrels of oil and 8.35M mcf of gas since January 1993, last reporting in July 2026. The leases carry 100 wells, so these are lease totals, not this well alone.
