Desert Willow F #8HA (API 42-227-40738) is a horizontal well in Howard County operated by Oxyrock Operating LLC, completed July 25, 2021 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued June 9, 2020, permitted to 8,300 ft.

It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Completion filings report 9 formation tops, including Rustler, Yates, San Andres, Glorieta.

Its lease has reported 1.09M barrels of oil and 2.44M mcf of gas since July 2021, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
