Darling North A #1 (API 42-461-38032) is a well in Upton County operated by Diamondback E&P LLC, completed August 18, 2013 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended 3 times) between 2012 and 2014, permitted to 10,877 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Abo, Wolfcamp, Cisco.
Its 2 leases have reported 251K barrels of oil and 2.67M mcf of gas since August 2013, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
