Ector County · TXL (Tubb) field · Injection · Vertical
Txl South Unit #7110 (API 42-135-38889) is a well in Ector County operated by Formentera Operations LLC, completed December 11, 2015 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 22, 2005, permitted to 6,554 ft.
It was permitted by Anadarko Petroleum Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Tubb, Wichita-Albany.
Its lease has reported 21.3M barrels of oil and 42.2M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 718 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 63.6K barrels injected in the 12 months reported through October 2025.

Well logs
1 log loaded from the RRC's log index, the latest received May 26, 2015. 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.
