Crane County · University Waddell (Devonian) field · Producing · Vertical
University Waddell Devonian Unit #319 (API 42-103-33758) is a well in Crane County operated by Formentera Operations LLC, completed June 5, 1989 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 16, 1986, permitted to 9,400 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Grayburg, Glorieta, Clear Fork.
Its lease has reported 2.18M barrels of oil and 3.88M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 41 wells, so these are lease totals, not this well alone.
