Ector County · TXL (Tubb) field · Producing · Vertical
Txl North Unit #914 (API 42-135-38478) is a well in Ector County operated by Formentera Operations LLC, completed May 8, 2004 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 18, 2003, permitted to 6,435 ft.
It was permitted by Anadarko Petroleum Corp. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Clear Fork, Tubb.
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.
