Upton Z Fee #24 (API 42-461-38684) is a well in Upton County operated by Diamondback E&P LLC, completed September 26, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 17, 2013, permitted to 5,000 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Rustler, Tansill, Yates, Seven Rivers.
Its lease has reported 2.8M barrels of oil and 2.8K mcf of gas since November 1994, last reporting in July 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
