University 50-12 West #1P (API 42-105-42084) is a well in Crockett County operated by Speartip Energy LLC, completed April 8, 2015.
The RRC has issued 2 drilling permits between 2014 and 2017, permitted to 9,000 ft.
It was permitted by Atropos Exploration Company and has since transferred to Speartip Energy LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Queen, San Andres, Leonard, Canyon.
Its 2 leases have reported 6.45K barrels of oil and 2.36K mcf of gas since July 2014, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
