Upton Z Fee #3

Plugged

Upton County · Concho Bluff North (Queen) field · Vertical

Upton Z Fee #3 (API 42-461-33523) is a plugged well in Upton County, plugged January 16, 2018, last operated by Diamondback E&P LLC.

The RRC has issued one drilling permit, issued January 10, 1995, permitted to 4,700 ft.

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

Completion filings report one formation top, including Queen.

Its lease has reported 2.8M barrels of oil and 2.8K mcf of gas since November 1994, last reporting volume in April 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
