Parks 4 #4 (API 42-329-35779) is a plugged well in Midland County, plugged August 29, 2024, last operated by Diamondback E&P LLC.

The RRC has issued 2 drilling permits between 2007 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 240K barrels of oil and 249K mcf of gas since March 2005, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
