Pier 21-24 Unit 1 #132 (API 42-317-42245) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed January 7, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued May 1, 2019, 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 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 4.15M barrels of oil and 10.4M mcf of gas since December 2019, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
