Txl North Unit #667W (API 42-135-01333) is a plugged well in Ector County, plugged December 26, 1991, last operated by Formentera Operations LLC.

The RRC has issued one drilling permit, issued June 26, 1991, permitted to 6,300 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 13.9M barrels of oil and 40.3M mcf of gas since January 1993, last reporting in July 2026. The lease carries 496 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
