Txl South Unit #3723 (API 42-135-37508) is a well in Ector County operated by Formentera Operations LLC, completed August 7, 1999.

The RRC has issued one drilling permit, issued June 25, 1997, permitted to 7,000 ft.

It was permitted by Anadarko Petroleum Corp. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 21.3M barrels of oil and 42.2M mcf of gas since January 1993, last reporting in July 2026. The lease carries 718 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 108K barrels injected in the 12 months reported through October 2025.

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