Four Corners Txl Fee A #2515U (API 42-461-38894) is a well in Upton County operated by Diamondback E&P LLC, completed October 22, 2013 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit, issued July 26, 2013, permitted to 11,227 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 137K barrels of oil and 369K mcf of gas since October 2013, last reporting volume in December 2024. The lease carries 4 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, the latest received May 27, 2014. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
