Tahoe-University B #2 (API 42-371-34477) is a well in Pecos County operated by Xhorizons Energy LLC, completed August 10, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 12, 1983, permitted to 3,000 ft.
It was permitted by Tahoe Oil & Cattle CO. and has since transferred to Xhorizons Energy LLC on the wellbore schedule.
Its lease has reported 47.5K barrels of oil and 37.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
