Nichols 15 #4 (API 42-227-37017) is a well in Howard County operated by Diamondback E&P LLC, completed November 21, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 4, 2012, permitted to 10,525 ft.

It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 242K barrels of oil and 1.26M mcf of gas since August 2008, 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.
