Apollo 38-1 Unit 2 #181 (API 42-317-45157) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed March 4, 2024 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 10, 2023, permitted to 9,140 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 2.36M barrels of oil and 8.42M mcf of gas since June 2023, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
