Four Corners Txl Fee #3316U (API 42-461-38374) is a well in Upton County operated by Diamondback E&P LLC, completed July 16, 2019 and listed as shut in on the RRC schedule, shut in August 1, 2018.
The RRC has issued one drilling permit, issued September 19, 2012, permitted to 11,169 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 7 formation tops, including Clear Fork, Sparberry, Spraberry, Dean.
Its lease has reported 2.87M barrels of oil and 10.4M mcf of gas since August 2011, last reporting volume in April 2026. The lease carries 90 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 17, 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.
