Long-Bristow 21-22 #1 (API 42-317-35042) is a plugged well in Martin County, plugged January 7, 2025, last operated by Diamondback E&P LLC.

The RRC has issued 2 drilling permits between 2007 and 2017, permitted to 12,000 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.

Its lease has reported 120K barrels of oil and 231K mcf of gas since April 2008, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
