Parks 36a #1 (API 42-329-35661) is a plugged well in Midland County, plugged September 4, 2025, 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 124K barrels of oil and 173K mcf of gas since July 2007, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
