Txl South Unit #5723D (API 42-135-42718) is a well in Ector County operated by Formentera Operations LLC, completed February 18, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 3, 2013, permitted to 6,495 ft.

It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Canyon, Connell, Devonian, Fusselman.

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.

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