East Rankin Unit 58-3 #13 (API 42-461-38117) is a well in Upton County operated by Saxum Opco LLC, completed September 1, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued May 18, 2012, permitted to 11,500 ft.

It was permitted by Diamondback E&P LLC and has since transferred to Saxum Opco LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Clear Fork, Strawn, Atoka.

Its lease has reported 169K barrels of oil and 1.35M mcf of gas since September 2012, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
