Txl #4 (API 42-135-06098) is a plugged well in Ector County, plugged June 16, 2009, last operated by Formentera Operations LLC.

The RRC has issued one drilling permit, issued May 8, 1991, permitted to 4,500 ft.

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

Completion filings report 3 formation tops, including Grayburg, San Andres, Holt.

Its 2 leases have reported 396K barrels of oil and 761K mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
