Txl S #1 (API 42-329-01084) is a well in Midland County operated by Cog Operating LLC, completed February 18, 1993 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 28, 1992, permitted to 13,180 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 6 formation tops, including San Andres, Spraberry, Wolfcamp, Pennsylvanian.

Its 3 leases have reported 4M barrels of oil and 36.3M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 91 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.
