Thomas 11 #4 (API 42-115-32031) is a well in Dawson County operated by Bechtel Investments Inc., completed July 4, 1984.
The RRC has issued one drilling permit, issued May 25, 1984, permitted to 5,200 ft.
It was permitted by Mesa Petroleum CO. and has since transferred to Bechtel Investments Inc. on the wellbore schedule.

Its lease has reported 1.84M barrels of oil and 294K mcf of gas since January 1993, last reporting in July 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
