University Waddell Devonian Unit #92W (API 42-103-33420) is a plugged well in Crane County, plugged January 19, 2004, last operated by Formentera Operations LLC.

The RRC has issued 2 drilling permits between 1984 and 1991, permitted to 9,500 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 4 formation tops, including Grayburg, Clear Fork, Pennsylvanian, Devonian.

Its 2 leases have reported 3.48M barrels of oil and 4.53M mcf of gas since January 1993, last reporting in July 2026. The leases carry 114 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
