University -25- #3
Crane County · McElroy (Devonian Upper) field · Vertical
University -25- #3 (API 42-103-33320) is a well in Crane County operated by Mobil Producing TX. & N.M. Inc., completed February 6, 1985.
The RRC has issued 3 drilling permits (amended once) between 1983 and 2011, permitted to 12,400 ft.
It was permitted by Chaparral Energy, L.L.C. and has since transferred to Mobil Producing TX. & N.M. Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Wolfcamp, Strawn, Woodford, Devonian.
Its 2 leases have reported 314K barrels of oil and 1.45M mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
