Windham 128 #1 (API 42-461-36355) is a well in Upton County operated by TS Oil LLC, completed November 18, 2009 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 13, 2009, permitted to 10,300 ft.

It was permitted by Mewbourne Oil Company and has since transferred to TS Oil LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Glorieta, Spraberry, Wolfcamp.

Its lease has reported 82.7K barrels of oil and 721K mcf of gas since November 2009, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
