Parks 4 #1 (API 42-329-35223) is a well in Midland County operated by Diamondback E&P LLC, completed March 1, 2005 and listed as shut in on the RRC schedule.
The RRC has issued 2 drilling permits between 2005 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 Clear Fork, Spraberry, 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.
