University Waddell Devonian Unit #5 (API 42-103-05379) is a well in Crane County operated by Formentera Operations LLC, completed January 24, 1962.
The RRC has issued one drilling permit (amended once), issued November 12, 2021, permitted to 9,410 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 Dune (Wolfcamp), Strawn, Devonian.
Its 2 leases have reported 2.19M barrels of oil and 3.89M mcf of gas since January 1993, last reporting in July 2026. The leases carry 42 wells, so these are lease totals, not this well alone.
