Douglas #3601 (API 42-329-35255) is a well in Midland County operated by Diamondback E&P LLC, completed November 9, 2005 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued February 15, 2005, permitted to 10,600 ft.

It was permitted by Perenco LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, San Andres, Clear Fork, Spraberry.

Its lease has reported 108K barrels of oil and 278K mcf of gas since April 2005, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
