Alexander 4-45 #1H (API 42-389-34267) is a horizontal well in Reeves County operated by Diamondback E&P LLC, completed December 7, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 28, 2014, permitted to 10,424 ft.

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

Completion filings report 8 formation tops, including Delaware, Castile, Bell Canyon, Cherry Canyon.

Its lease has reported 758K barrels of oil and 4.88M mcf of gas since November 2014, 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.
