University Devonian A 37 #4 (API 42-103-35880) is a well in Crane County operated by Formentera Operations LLC, completed December 4, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended 3 times), issued August 10, 2011, permitted to 9,840 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Pennsylvanian, Woodford, Devonian.
Its 2 leases have reported 226K barrels of oil and 537K mcf of gas since November 2011, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
