State Armstrong 9-4 Unit #1WA (API 42-389-38077) is a horizontal well in Reeves County operated by Blue Arrow Operating LLC, completed June 6, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 20, 2019, permitted to 11,400 ft.

It was permitted by Diamondback E&P LLC and has since transferred to Blue Arrow Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Delaware, Bone Spring, Wolfcamp, Bell Canyon.

Its lease has reported 1.09M barrels of oil and 1.27M mcf of gas since June 2019, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
