Liberty-Dyer 38 #1 (API 42-317-34773) is a well in Martin County operated by Diamondback E&P LLC, completed October 5, 2007 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2006 and 2018, 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 6 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.

Its lease has reported 299K barrels of oil and 434K mcf of gas since October 2007, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
