Ector County · TXL (Tubb) field · Producing · Vertical
Txl North Unit #1009 (API 42-135-39556) is a well in Ector County operated by Formentera Operations LLC, completed November 5, 2009 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 8, 2008, permitted to 6,890 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 13.9M barrels of oil and 40.3M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 496 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Sep 26, 2011. Cased hole, Density, 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.
