University O 25 #5 (API 42-103-33281) is a well in Crane County operated by Formentera Operations LLC, completed September 9, 2011.
The RRC has issued 2 drilling permits between 1983 and 2023, permitted to 9,200 ft.
It was permitted by Slant Operating, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Pennsylvanian, Barnett, Devonian.
Its 2 leases have reported 208K barrels of oil and 1.41M mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
