Tahoe-University -Bta- #1 (API 42-371-35528) is a plugged well in Pecos County, plugged August 14, 1997, last operated by Primal Energy Corporation.
The RRC has issued one drilling permit, issued May 13, 1985, permitted to 3,000 ft.
It was permitted by Tahoe Oil & Cattle CO. and has since transferred to Primal Energy Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Tansill, Yates.
Its 2 leases have reported 33 barrels of oil and 1.37K mcf of gas since January 1993, last reporting in September 1997. The leases carry 3 wells, so these are lease totals, not this well alone.
