El Rey 28-16 #1DN (API 42-227-42565) is a horizontal well in Howard County operated by Diamondback E&P LLC, completed May 12, 2025 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 15, 2024, permitted to 11,000 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 10 formation tops, including Yates, Seven Rivers, San Andres, Glorieta.

Its lease has reported 875K barrels of oil and 511K mcf of gas since December 2024, last reporting in July 2026. The lease carries 5 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.
