Quinn 8 #1 (API 42-227-35040) is a plugged well in Howard County, plugged November 20, 2025, last operated by Diamondback E&P LLC.

The RRC has issued 3 drilling permits (amended once) between 1996 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 9 formation tops, including Clear Fork, Spraberry, Wichita-Albany, Dean.

Its 2 leases have reported 181K barrels of oil and 51.6K mcf of gas since September 1996, last reporting in July 2026. The leases carry 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.
