Rock Unit #2 (API 42-329-35269) is a well in Midland County operated by Diamondback E&P LLC, completed August 12, 2005 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2005 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 7 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.

Its lease has reported 176K barrels of oil and 492K mcf of gas since February 2005, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
