Daniel SN 21-16 03 #203H (API 42-173-36978) is a horizontal well in Glasscock County operated by Diamondback E&P LLC, completed June 10, 2015 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 30, 2014, permitted to 8,407 ft.

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

Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 192K barrels of oil and 2.77M mcf of gas since June 2015, last reporting in July 2026. The lease carries 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.
