Nixon 177 #13 (API 42-413-32856) is a well in Schleicher County operated by Upp Operating LLC, completed August 9, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 18, 2012, permitted to 4,300 ft.
It was permitted by Highmount Expl & Prod Texas LLC and has since transferred to Upp Operating LLC on the wellbore schedule.

Its lease has reported 8.5K barrels of oil and 61.2K mcf of gas since June 2012, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
