Txl N 43-4 #5 (API 42-329-36078) is a well in Midland County operated by Diamondback E&P LLC, completed November 28, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 8, 2008, permitted to 10,261 ft.
It was permitted by Forest Oil Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Rustler, Yates, Grayburg, Clear Fork.
Its lease has reported 141K barrels of oil and 279K mcf of gas since December 1997, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 1, 2011. Resistivity. 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.
