Txl 41 #8 (API 42-135-42640) is a well in Ector County operated by Formentera Operations LLC, completed December 9, 2013.
The RRC has issued 2 drilling permits between 2013 and 2023, permitted to 7,500 ft.
It was permitted by Slant Operating, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 7 formation tops, including San Andres, Glorieta, Tubb, Clear Fork.
Its 2 leases have reported 21.4M barrels of oil and 42.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 726 wells, so these are lease totals, not this well alone.
