Four Corners Txl Fee C #2146U (API 42-461-39731) is a well in Upton County operated by Diamondback E&P LLC, completed May 7, 2015 and listed as shut in on the RRC schedule, shut in May 1, 2015.
The RRC has issued one drilling permit, issued April 8, 2015, permitted to 473 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 9 formation tops, including Devonian, Ellenburger, Fusselman, Grayburg.
Its lease has reported 2.33M barrels of oil and 8.95M mcf of gas since August 2013, last reporting volume in April 2026. The lease carries 48 wells, so these are lease totals, not this well alone.
