Darling North A #4 (API 42-103-36368) is a well in Crane County operated by Diamondback E&P LLC, completed April 18, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended 3 times), issued August 13, 2014, permitted to 10,395 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 10 formation tops, including Rustler, Yates, Seven Rivers, San Andres.

Its lease has reported 140K barrels of oil and 1.2M mcf of gas since August 2013, last reporting in July 2026. The lease carries 3 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.
